Opis:
In this research, estimation potential of Aquacrop model under deficit irrigation and salinity conditions were evaluated for winter wheat grown under arid and semi-arid climates. Five different irrigation strategies and irrigation water salinity levels (0.5, 5, 7.5, 10, 15 dS m-1 ) were taken with the model to estimate deficit irrigation and salinity scenarios. Wheat grain yield, biomass production and canopy cover were simulated under deficit and salinity stresses. According to estimation of the model; the deficit irrigation with water reduction of more than 75 % of full irrigation was applied at growth stages of wheat, revealed the significant reduction in grain yield, biomass and canopy cover as compared with full irrigation practice. The increase in irrigation water salinity caused a significant decrease in grain yield and biomass value. It was compared to the 0.5 dS m-1 salinity level, a low value of 3% was obtained for the 5 dS m-1 salinity level. Yield loss of 7.5, 10 and 15 dS m-1 salinity levels were found to be 18.97%, 42.5% and 85.6% respectively. Also, increasing irrigation water depth in saline treatments resulted in increased grain and biomass yield. For sustainable water management in agriculture area, using simulation model such as Aquacrop is useful tolls to estimate effect of applied water depth and quality of irrigation water on crop yield.

Opis:
The variety of technological conditions and raw materials from which biochar is produced is the reason why its soil application may have different effects on soil properties and plant growth. The aim of this study was to evaluate the effect of the addition of wheat straw and Miscanthus giganteus straw (5 t DM ha-1) and biochar obtained from this materials in doses of 2.25 and 5 t DM ha-1 on soil enzymatic activity, soil ecotoxicity, and plant yield (perennial grass mixture with red clover). The research was carried out under field conditions on soil with the granulometric composition of loamy sand. No significant effect of biochar amendment on soil enzymatic activity was observed. The biochar-amended soil was toxic to Vibrio fischeri and exhibited low toxicity to Heterocypris incongruens. Application of wheat straw biochar and M. giganteus straw biochar in a dose of 5 t DM ha-1 contributed to an increase in plant biomass production by 2 and 14%, respectively, compared to the soil with mineral fertilisation. Biochars had a more adverse effect on soil enzymatic activity and soil ecotoxicity to H. incongruens and V. fischeri than non-converted wheat straw and M. giganteus straw, but significantly increased the grass crop yield.

Opis:
The aim of this paper was to review 100 years of Polish studies on sulphur fertilisation and its effects on the growth and development of plants, the chemical composition and impact of sulphur compounds on the health of plants, and its fungicidal activity. In the reviewed studies sulphur deficiency generally delayed vegetative growth, caused the dying out of the growth cone, yellow discolouration of the generative and vegetative organs and delayed maturation. Observations of plants have demonstrated that sulphur is essential for normal photosynthetic functions. Plants suffering from a lack or shortage of sulphur had pale green or yellowish, narrow, short and small leaves, and a smaller than normal root system, which was associated with reduced chlorophyll synthesis. The availability of sulphur was found to enatil an improved uptake of nitrogen by plants, thus affecting their quality and optimising the N:S ratio. Fertilisation with sulphur increased the total content of sulphur and sulphates in plants. Findings from studies on the effect of sulphur on the content of macroelements in tested plants are inconclusive. Sulphur used in excess disturbed the ionic balance in plants and indirectly affected the intensity and level of uptake of other nutrients. The results of studies investigating the impact of sulphur on changes in the content of heavy metals were ambiguous and demonstrated either synergistic or antagonistic interactions. Generally, sulphur fertilisation increased the content of glucosinolates in plants and improved their nutritional value. Most studies also showed that sulphur fertilisation improved the disease resistance of plants. Some studies have also demonstrated an increased content of glucosinolates in plants fertilised with sulphur, which stimulated natural resistance to fungal infections.

Opis:
The COVID-19 outbreak has seriously affected the global food security at a time when it was significantly compromised by the effects of climate change and armed conflicts. The impact of the pandemic and quarantine restrictions imposed in response to the deadly virus brought humanity face-to-face with a new threat – that of food insecurity – which contributed to a high social demand for state-of-the-art methods of improving the cereal production efficiency. The aim of the study is to develop and implement a methodological approach to enhancing the cereal production efficiency. The methodology of the study relies on time series that made it possible to determine the main trends in regional cereal production and make projections. Application of the suggested approach in the Kostanay region revealed that this region was among the key cereal producers in the country. In 2019, the region was affected by extreme weather, which caused a sharp decline in cereal production. The present study, however, projects large opportunities for cereal production growth in the region and a significant increase in cereal production in the future. In addition, the paper suggests the following action plan to improve efficiency of the cereal production sector in the Kostanay region: streamlining of state support arrangements for cereal producers; development of affordable crop insurance products; systemic steps to increase cereal yields; development of logistic infrastructure; comprehensive monitoring of cereal production to develop a system of rapid response to changes in the external environment.

Cassava peel has shown the potential of been efficient as a carrier material for biofertilizer production. Cassava peels are in large quantity and practically of no economic value in many developing nations, thus, satisfy criteria for its adoption as a biofertilizer-carrier material. The study evaluated the potential of cassava peel as a biofertilizer nutrient carrier and its effect on maize growth. Cassava peel has been found to have low moisture content and bulk density, high porosity and good water absorption capacity which aids inoculant organism survival as indicated in the significant (p< 0.05) increased in plant growth parameters, which stands higher (p < 0.05) over the control, with highest plant height and number of leaves produced at an application rate of 12t ha-1 biofertilizer.

Opis:
In Morocco, agriculture is an important sector that contributes to the country’s economy and food security. Accurately predicting crop yields is crucial for farmers, policy makers, and other stakeholders to make informed decisions regarding resource allocation and food security. This paper investigates the potential of Machine Learning algorithms for improving the accuracy of crop yield predictions in Morocco. The study examines various factors that affect crop yields, including weather patterns, soil moisture levels, and rainfall, and how these factors can be incorporated into Machine Learning models. The performance of different algorithms, including Decision Trees, Random Forests, and Neural Networks, is evaluated and compared to traditional statistical models used for crop prediction. The study demonstrated that the Machine Learning algorithms outperformed the Statistical models in predicting crop yields. Specifically, the Machine Learning algorithms achieved mean squared error values between 0.10 and 0.23 and coefficient of determination values ranging from 0.78 to 0.90, while the Statistical models had mean squared error values ranging from 0.16 to 0.24 and coefficient of determination values ranging from 0.76 to 0.84. The Feed Forward Artificial Neural Network algorithm had the lowest mean squared error value (0.10) and the highest R² value (0.90), indicating that it performed the best among the three Machine Learning algorithms. These results suggest that Machine Learning algorithms can significantly improve the accuracy of crop yield predictions in Morocco, potentially leading to improved food security and optimized resource allocation for farmers.

Opis:
The paper presents results of studies on the influence of liming and mineral fertilization on the yields and boron content of potato tubers and green matter of fodder sunflower grown in four and three rotations, respectively, on soil developed from loess. The experiment was set up on a field submitted to long-term fertilization and located in the village Krasne near Rzeszow, lying in the Rzeszów Foothills (Poland). Boron was determined colorimetrically with diantrimide after digestion of dried plant material at 550°C and dissolution of the residue in hydrochloric acid solution. Average yields of potato tubers and green matter of fodder sunflower were higher after liming, but statistical significance was confirmed only for fodder sunflower. Mineral NPK fertilization, regardless of liming, significantly enhanced the yield of green matter of fodder sunflower and, in most fertilization treatments, raised potato tuber yields. Potato tubers accumulated much smaller amounts of boron (2.2-7.5 mg kg-1 DM) than aerial parts of fodder sunflower (20- 60 mg kg-1 DM). The boron content was significantly lower in potato tubers from the limed variant than in plants from the non-limed field. The response of sunflower to soil liming was opposite. The mineral fertilization applied, regardless of liming, had no significant effect on the boron content of potato tubers. Mineral nutrition reduced the boron content in the sunflower biomass under the influence of increasing doses of nitrogen and against the background of constant phosphorus-potassium fertilization.

In order to evaluate the ability of the crop water stress index to estimate grain yield and water productivity of maize and black gram in the climatic conditions of Urmia (Iran), research was conducted under the conditions of single-row drip irrigation. This study was conducted in a randomized complete block design with four irrigation levels including 50 (I1), 75 (I2), 100 (I3) and 125 (I4) percent of the water requirements of the plants with three replications. The mean crop water stress index values for the I1, I2 and I3 treatments were 0.53, 0.44, and 0.28, respectively during the growth period of maize, and 0.37, 0.23, and 0.15 for black gram, respectively. In the present study, the correlation between the crop water stress index and the grain yield and also the water productivity of maize and black gram was high. According to the results, the highest grain yield for maize and black gram was obtained at crop water stress index values of 0.28 and 0.15, respectively. Therefore, these values are recommended for the irrigation scheduling of the plants. It should be noted that the maximum water productivity index for maize and black gram was obtained at crop water stress index values of 0.44 (I2) and 0.37 (I1), respectively, which are the values recommended for irrigation scheduling under restricted access to water.

W pracy przedstawiono syntetyczną analizę wyników badań lizymetrycznych plonowania i ewapotranspiracji użytków zielonych w naturalnych warunkach dostatku wody w glebie oraz w warunkach zróżnicowanego potencjału wody w glebach torfowo-murszowych i murszowatych w okresach suszy meteorologicznej umiarkowanej, silnej i ekstremalnej na Polesiu Lubelskim. Stwierdzono, że optymalna wilgotność gleby na użytkach zielonych zapewnia maksymalne plony siana. Plony te w dekadach i okresach IV–V, VI–VII, VIII–IX są uzależnione od czynników meteorologicznych i ewapotranspiracji maksymalnej. W pracy oszacowano aktualne i końcowe maksymalne plony siana w dekadach i okresach IV–V, VI–VII, VIII–IX w zależności od prognozowanych średnich dobowych wartości ewapotranspiracji maksymalnej. Określono wpływ wilgotności gleby na aktualne i końcowe rzeczywiste plony siana za pomocą współczynników glebowo-wodnych ks2 dla dekad i okresów IV– V, VI–VII, VIII–IX w zależności od prognozowanych bezwzględnych wartości potencjału wody glebowej. Oszacowano aktualne i końcowe rzeczywiste plony siana w dekadach i okresach IV–V, VI– VII, VIII–IX na podstawie zmniejszania plonów maksymalnych, wyrażonego wartością współczynników glebowo-wodnych ks2. Oszacowane aktualne i końcowe rzeczywiste plony siana odnoszone do plonów maksymalnych ilustrują wpływ potencjału wody w glebie na dynamikę przyrostu plonu aktualnego i końcowego. Dowodzą one, jak istotne znaczenie dla optymalnego plonowania użytków zielonych ma utrzymywanie optymalnego uwilgotnienia gleby.
The paper presents a synthetic analysis of the results of lysimeter investigations on grassland yield and evapotranspiration under natural sol water supply and different soil water potential in peatmoorsh and moorsh soils, in periods of moderate, severe and extreme meteorological droughts, led in Polesie Lubelskie. It has been proved that the optimum soil moisture ensures the maximum hay field from grassland. Yields are dependent on meteorological factors and the maximum evapotranspiration. In the study current and final maximum hay yields are estimated in dependence on predicted maximum mean in 10-day and periods IV–V, VI–VII, VIII–IX evapotranspiration. Effect of soil moisture on current and final actual hay yield is quantified using soil-water coefficients ks2 for decades and periods IV–V, VI–VII, VIII–IX depending on soil water potential. Current and final actual hay yield is estimated by reduction of maximum yield by soil-water coefficients ks2. These yields related to maximum yield show the effect of soil water potential on the actual and final growth dynamics. They prove as important for optimal yield of grassland is maintaining high soil moisture.

Six experiments were conducted for the enhancement in seed cotton yield by increasing water use efficiency and water savings in case of different planting methods of cotton (Gossypium hirsutum L.) crop during the years 2014 & 2015, at three different locations in cotton zone of Punjab (Pakistan) province. The planting methods were, flat planting and no earthing up, flat planting and earthing up after 1st irrigation, flat planting and alternate row earthing after 1st irrigation, flat planting in 112.5/37.5 cm apart paired rows and earthing up after 1st irrigation, ridge planting and bed planting. Cotton crop obtained a maximum benefit from the available water at all three locations in case of flat planting with alternate row earthing up (P3) by predicting a maximum water use efficiency up to 6.79 kg ha-1 mm-1and maximum seed cotton yield of 3432.50 kg ha-1. Maximum water savings of 25.60% was recorded in the same method (P3) during the year 2014, while minimum (-0.17%) was observed in ridge planting (P5) at location number 1 in the same year.

The objective of this study is to recover sludge from the Dar Gueddari sewage treatment plant and use it in the cultivation of corn in the open field on clay soil. To do this, four doses were tested against two types of controls: a control without addition of sludge and another with the addition of nitrogen-based fertilisers (200 kg N, 100 kg P and 100 kg K). The short-term effects indicated that the application of the sludge had a beneficial effect on the fertilising qualities of the soil and therefore on the crop yield. The monitoring of the agronomic parameters of the maize plant showed that the growths and the yields varied according to doses of the sludge. In grain yield, the difference between plot E4 and E0 was around 3.3 Mg∙ha-1. In addition, the plots treated with large sludge doses experienced improvements in total nitrogen and organic matter. During the second season, the results obtained showed decrease in nutrients (nitrogen and phosphorus). It emerged from the C:N ratio which was <8. This indicated a good mineralisation of the organic matter (OM) which was average of 2.48 ±0.04% and 2.5 ±0.01%, respectively in the E4 and E5 treatments. In addition, the amounts of N, P and Ca in dry matter (DM) increased with increasing the dose of sludge. During the 2017 season, the highest values were detected in plot E5 with averages of 1.6% in N and 0.53% in P.
