Opis:: Epidemiological studies reported an inverse association between the consumption of legumes and the incidence of age-related diseases. This trend could be attributed to the presence of antioxidant compounds, especially phenolic and flavonoid compounds. In this paper, five pea (Pisum sativum L.) and twelve chickpea (Cicer arietinum L.) accessions, having different characteristics and geographical origin, were characterised in terms of antioxidant activity, as well as macro- and micro-nutrient composition. The antioxidant activity has been evaluated using both DPPH (2,2-diphenyl-1-picrylhydrazyl) and ABTS (2,2’-azino-bis (3-ethylbenzthiazoline-6-sulfonic acid) radical scavenging capacity assays. Chickpea and pea accessions showed a different behaviour in the presence of these different radicals. Chickpea accessions were characterised by significantly higher DPPH• scavenging activity, while peas showed a significantly higher value of antioxidant activity evaluated using the ABTS assay. Pea accessions had the highest content of total phenolic compounds, Zn, and Cu. A positive correlation was found between some minerals, such as Zn, Cu and P, and the ABTS•+ scavenging activity. Black and brown chickpea accessions showed significantly higher contents of anthocyanins, Mn, Mg, and Ca, which were positively correlated with the antioxidant activity assessed with the DPPH assay. Despite the dataset investigated in our study included a limited number of accessions, it was possible to highlight the influence of the chemical composition on the antioxidant activity due to the high phenotypic diversity found between the accessions, emphasising the importance of selecting the antioxidant activity assay according to the matrix to be evaluated.

Opis:: Coccinia abyssinica (Lam.) Cogn. (local name anchote) is a tuber crop that belongs to the family Cucurbitaceae and it is cultivated for food and medicinal uses. It has relatively high quality of nutrient composition compared to other tuber crops, and is considered as the leading proteinous root crop with a high calcium content. Therefore, cooked anchote tubers are highly recommended for patients with broken or fractured bones. Anchote also contains alkaloids, phenols, tannins, flavonoids, and saponins. Although anchote is principally cultivated for its tubers, farmers prefer propagation by seeds as they are easy to store. Farmers select high-quality fruits for future seeds, based on the size of fruits and tubers. Since diseases and pests rarely affect the tubers, protection is not common. However, the fruit fly can damage the fruits, which predisposes them to decay. Although anchote has very high potential as a food security crop, it is neglected and underutilized and has received very limited research attention. Research published so far covers its ethnobotany, nutritional and anti-nutritional composition, traditional methods of reproduction, in vitro reproduction, somatic embryogenesis, anther breeding, and morphological and molecular genetic diversity. This article includes an analysis of previous and current research achievements, presents findings in a comprehensive way, and suggests future direction in crop improvement using biotechnological tools.

Opis:: Weed competition in southern Brazil is one of the main limiting factors for Oryza sativa L. (flooded rice) yield. Echinochloa spp. (barnyardgrass) occurs at a high frequency. Although the potential for weed interference in this cereal is well known, there is little information available about the impact of nutrient competition on rice. Thus, this study aimed to evalu- ate the relationship between the increase of the barnyardgrass population and the develop- ment and nutrition of flooded rice plants at different stages of development. The treatments consisted of growing populations of barnyardgrass competing with the crop from stage V4, which were: 0, 1, 6, 13, 100 and 200 plants · m−2 . The experimental design was random- ized blocks with two replications, and the experimental units were plots 1.53 m wide by 5 m long. Plant biomass, nutrient uptake and loss of productivity were determined with three replications. An increase in the barnyardgrass population reduced the dry mass of rice leaves and stems, regardless of the evaluation period and the vegetative or reproduc- tive period. Barnyardgrass plants had a significant impact on the reduced grain yield of a flooded rice crop, mainly due to high nutrient competitiveness, especially N in the veg- etative period and K in the reproductive period. Barnyardgrass caused a loss of yield by unit · m−2 of 1.13%. The competition for N between rice and barnyardgrass plants was higher in the vegetative period, while for K, Ca and Mg the highest competition occurred in the reproductive period.

Opis:: Limited information on the mineral elements constituent of ackee Blighia sapida K.D. Koenig and Cola millenii K. Schum are responsible for the underutilization of parts of this tree for health benefit purposes in West Africa. This study comparatively investigated the mineral nutrient content of both B. sapida and C. millenii pods. The results of the mineral element composition revealed that ackee (B. sapida) pod is high in Na 1.325%, Ca 0.032%, Mg 0.033%, P 0.017% and K 0.077%, compared to C. millenii with Na 0.663%, Ca 0.019%, Mg 0.013%, P 0.004% and K 0.013%, respectively. We also noted that the pods of B. sapida are rich in Fe 0.135%, when compared to 0.045% of Fe present in C. millenii pods. In contrast, C. milleni pods are rich in Cu 0.086% when compared to B. sapida pods at 0.054%. Also C. milleni pods contain Mn 0.001%, Zn 0.006%, Pd 0.006%, Cr 0.0002% and Cd 0.00002% while B. sapida contains Mn 0.003%, Zn 0.005%, Pd 0.004%, Cr 0.003% and Cd 0.00008%, respectively. These results indicate that ackee pods are good sources of Sodium and Iron, when compared with C. millenii. The results also reveal that the levels of Lead, Chromium and cadmium are very low in both samples, making them safe for human consumption.

Opis:: The aim of the three-year pot experiment was to determine the effect of standard mineral fertilization enriched with sulfur and iron on the content of nitrogen and sulfur in plants and on nutrient utilization by plants. Abundance of sulfates in soil after sulfur fertilization was also assessed. The direct effect of fertilization was assessed during the first and second year of the pot experiment, and the after-effect was analyzed during the third year. Rape (first year) and maize (second and third year) were the test plants. Solid mineral fertilizers (A: a mixture of ammonium nitrate and dolomite; B: a mixture of ammonium nitrate and sulfate) enriched with iron sulfate were used. Nitrogen content in the plants varied depending on applied fertilization as well on plant species and part. Sulfur application increased sulfur content in the aboveground parts of plants by 25-457% and in roots by 95-708%. Iron application ambiguously influenced nitrogen and sulfur content in the plants. Hovewer, simultaneous application of iron and sulfur (as fertilizer B enriched with iron) resulted in the highest coefficient of nitrogen (84%) and sulfur (39%) utilization. Sulfur fertilization caused a 5-20 fold increase in sulfate sulfur content in the soil.

Opis:: The research objective was to determine and compare dry matter, crude protein, mineral elements (total), dietary fiber, easily hydrolysable sugars, vitamin C, and minerals (K, Na, Mg, Cu) as well as the content of epicatechin and phenolic acids (homovanillic, chlorogenic, caffeic, coumaric, and ferulic) in the flesh and peel of ‘Šampion’ cv. apples grafted on 4 different rootstocks types: M.26, P2, M.9, and P22 in 2014–2015. The apples from trees grafted on the P22 rootstock had the highest content of dry matter, crude protein, fiber, easily hydrolysable sugars, and vitamin C. The highest mineral compound concentration was exhibited by apples from trees growing on rootstocks P22, P2, and M.9. The highest concentration of phenolic acids was determined in the peel of fruits from trees growing on P22 and M.9. The observations confirm that rootstocks characterized by the lowest growth rate (P22, M.9) ensure the highest accumulation of nutrients in ‘Šampion’ fruits.

Opis:: Carissa carandas are important medicinal plants in Tamil Nadu. The entire plant has medicinal values. Carissa carandas plants are used to cure various diseases such as asthma, skin disease, cough, cold and tuberculosis. They usually are prepared as fresh juices rather than boiling water and decoction leaves and flowers of Carissa carandas. The juice from the leaves play an important role in this matter. Usually about 30 ml of the juice is taken thrice a day with honey, acting as relieving agent for irritable cough due to its soothing action on the nerve and by liquefying the sputum, which makes expectoration easier. Carissa carandas are important traditional remedies in Tamil Nadu.

Opis:: Background. The sorghum (C4) species has a high potential for accumulation of photosynthetic radiation. It is possible to obtain a high biomass yield after meeting the fertilization needs of plants, especially as regards nitrogen. Material and methods. In 2013–2015 at the Experimental Station Pawłowice, which belongs to the Department of Crop Production, a field experiment was conducted that aimed to assess the usefulness of the fertilizer YaraRega to fertilize sweet sorghum. Two methods of using the fertilizer were used: broadcasting application and fertigation, using two rates (40 and 80 kg N per ha), and were compared with the control (without fertilization). The fertilizer in the foliar form was applied in two solutions: 0.20 and 0.40%, respectively, for rates of 40 and 80 kg N per ha. The study estimated the effect of fertilization on the productivity of fresh and dry matter and the effectiveness of these treatments. Results. The statistically significant increase in the fresh matter yield obtained under the influence of nitrogen rates was about 25% (after fertilization with 40 kg N per ha) and 32% (after the application of 80 kg N per ha). Taking into account also the dry matter yield, only fertilization with 40 kg N per ha caused a significant increase in the yield compared with the control. Fertilization with a rate of 40 kg N per ha caused an increase in the fresh matter yield of about 300 and 334 kg per 1 kg of nitrogen used after of broadcasting and fertigation application methods respectively. Agronomic efficiency expressed in dry matter yield amounted to 75 and 76 kg per 1 kg of nitrogen used. Conclusion. YaraRega is recommended to be applied to sorghum with the fertigation method. No toxic effect on sorghum plants was observed after an application of the 0.4% solution.
W latach 2013–2015 przeprowadzono badania mające na celu ocenę wpływu nawozu YaraRega na plon, cechy morfologiczne i właściwości chemiczne sorga cukrowego. YaraRega jest nową formulacją nawozów zalecaną do stosowania łącznie z nawadnianiem. Nawóz stosowano dwiema metodami, w tym samym terminie, w dwóch dawkach: poprzez aplikację powierzchniową oraz fertygację, w dawce $90$ i $180 kg⋅ha^(-1)$ masy nawozowej (co odpowiadało $40$ i $80 kg⋅ha^(-1)$ N) w porównaniu z kontrolą (bez nawożenia). Nawóz w formie roztworu zastosowano w dwóch stężeniach 0.20 i 0.40% (odpowiednio dla dawki $90$ i $180 kg⋅ha^(-1)$ masy nawozowej). Określono wpływ nawożenia na wielkość plonu świeżej i suchej masy oraz efektywność tego zabiegu. Pod wpływem nawożenia uzyskano statystycznie istotny większy plonu świeżej masy o 25% (po nawożeniu $90 kg⋅ha^(-1)$) i o 32% (po zastosowaniu $180 kg⋅ha^(-1)$ masy nawozowej). Nawożenie dawką $40 kg⋅ha^(-1)$ N spowodowało istotny wzrost plonu suchej masy o 300 kg (powierzchniowe nawożenie) i o 334 kg (fertygacja) na kg zastosowanego azotu. Efektywność agronomiczna wyrażona w kg suchej masy na kg azotu wynosiła odpowiednio dla obiektów nawożonych powierzchniowo i poprzez fertygację $75$ i $76 kg⋅kg^(-1)$ N.

Opis:: Despite the importance of calcium in many fruit species and the effects of calcium application, there is little or no reliable information on the effect of CaCl2 spray at different fruit development stages on the fruit mineral nutrient content during the growing season and at harvest. Therefore, this study has been conducted to evaluate the effect of calcium chloride (CaCl2, 15 g L-1) spray at different fruit development stages on the accumulation Ca and other macronutrients in cv. Hayward kiwifruit grown at two locations. In order to find the absorbality of Ca at different spraying times, fruits were harvested 7 days after a Ca treatment. Additionally, the mineral composition of kwifruit was determined at the stage of harvest ripeness. The results showed that the absorbality of Ca by kiwifruit from Ca spray decreased significantly with the progressing fruit development. The highest fruit Ca content was found when the fruit plants were sprayed at 35+80 DAFB and 35+80+120 DAFB, irrespectively of the location of an orchard. At a later Ca spraying application, the N content in kiwifruit significantly decreased, but the K and Mg content slightly increased. In contrast, the K/Ca, N/Ca, Mg/Ca and (K+Mg)/Ca ratios of CaCl2 sprayed fruits was lower than in the control and the ratio values were more balanced in the Ca treated fruit than in the control. Overall, three CaCl2 (15 g L-1) sprays could effectively improve the fruit quality by balancing the Ca ratio to other macronutrients. Therefore, Ca spray treatments could be a recommended treatment in growing cv. Hayward kiwifruit.

Opis:: During 2012 and 2013 we investigated impact of quinces MA and BA.29 rootstocks on leaf macro- and micronutrients amount at 60 days after full bloom (DAFB) and deviation from optimum percentage (DOP and ΣDOP indexes) of three pear cultivars grown at Cacak region on heavy and acidic soil. Results showed that rootstocks significantly influenced leaf P, Ca and B levels, whereas impact on other leaf nutrients is minor. Quince MA increased leaf P and Ca contents, while BA.29 induced higher leaf B level. Stronger effect than rootstock on leaf nutrients had cultivar, although differences among them for leaf N, Mg and Fe were not significant. Leaf of ‘Abbé Fetel’ on BA.29 had the highest K, Ca, Cu and B amounts, whereas on MA this cultivar had the highest Mn concentration. Also, ‘Abbé Fetel’ alongside with ‘Conference’ on MA had the highest and similar leaf Ca, Cu and Zn amounts. ‘Starking Delicious’ on BA.29 had the highest leaf P content. The DOP index showed high deficiency of K and Mn on both rootstock and Ca on BA.29. Other leaf nutrients tended to have a DOP values close to the optimum level in general. According to ΣDOP index, BA.29 induced better balanced leaf nutritional values as compared to MA for all nutrients. Among cultivars, ‘Abbé Fetel’ on both rootstocks and ‘Conference’ on BA.29 showed the best balanced nutritional values, whereas ‘Starking Delicious’ exhibited a wider imbalance in nutritional values for all nutrients.
W latach 2012 i 2013 badano wpływ podkładek pigwy MA i BA.29 na ilość makro- i mikroelementów 60 dni po pełnym kwitnieniu (DAFB) oraz odchylenie od optymalnego wskaźnika procentowego (DOP i ΣDOP) trzech odmian gruszy w rejonie Cacak na ciężkiej kwaśnej glebie. Na podstawie wyników wnioskuje się, że zastosowane podkładek istotnie wpłynęło na poziom P, Ca i B natomiast ich wpływ na inne składniki liści był niewielki. Zastosowanie podkładki pigwy MA zwiększyło zawartość P i Ca, natomiast podkładki BA.29 powodowało wyższy poziom B. Odmiana miała większy wpływ na składniki liścia, chociaż różnice dotyczące N, Mg i Fe nie były istotne. Liść ‘Abbé Fetel’ na podkładce BA.29 miał największą zawartość K, Ca, Cu i B, a na MA odmiana ta wykazywała największą zawartość Mn. ‘Abbé Fetel’ i ‘Conference’ na podkładce MA miały największą i podobną zawartość Ca, Cu i Zn w liściu. ‘Starking Delicious’ na podkładce BA.29 miał największą zawartość P w liściu. Wskaźnik DOP ujawniał wysoki niedobór K i Mn na obu podkładkach, a w przypadku do K – na BA.29. Inne składniki liścia miały wartości DOP zbliżone to poziomu optymalnego. Według indeksu ΣDOP, zastosowanie podkładki BA.29 sprawiało, że wartości odżywcze liścia były bardziej zrównoważone w porównaniu z podkładką MA w odniesieniu do wszystkich elementów. ‘Abbé Fetel’ na obydwu podkładkach, a ‘Conference’ na BA.29, wykazywały najlepiej zbalansowane wartości odżywcze, natomiast ‘Starking Delicious’ wykazywał większy brak równowagi w wartościach odżywczych dla wszystkich elementów.

Opis:: The yield increase of vegetables, including common onion (Alium cepa L.), is of great interest to growers. However, higher yield often leads to what is known as genetic dilution of mineral density. A technology of onion fertilization based on elemental sulfur (S0) fertilizers seems to be a simple agronomic measure preventing a decrease in the nutrient concentration in onion bulbs. To verify this hypothesis, field studies were conducted in the 2009 and 2010 seasons. A two-factorial trial consisted of five sulfur fertilizers: Sw (crude form of S0), Sm (micronized S0), SmCu (Sm enriched with copper 0.25%), SmZn (Sm enriched with zinc 0.5%), and AS (ammonium sulfate); and, as the second factor, of two doses of S: 30 and 60 kg ha-1. The NPK plot, included as an independent experimental variant, was used as the control. Yield of onion increased by 13% in response to 30 kg S ha-1, and by 44% when fertilized with 60 kg S ha-1. The yield of bulbs was significantly affected by increasing magnesium and negatively by sodium concentration. The increase in both bulb yields and dry matter content resulted in a simultaneous decrease in nutrient density, except sulfur. The strongest dilution effect was observed for sodium (-33%), iron (-19%), magnesium (-17%) and phosphorus (-16%). Such a negative development can be prevented by applying sulfur fertilizers in an appropriate form. The concentrations of N, P, K, N, and Cu responded most demonstrably to the added ammonium sulfate. The concentrations of S, Zn, Cu, Mn, and Fe were affected by the micronized form of S0 enriched with zinc. The magnesium concentration was the highest in plants fertilized with the crude form of S0.
