Opis:
Short white rice grains produced locally from Mahaica, Guyana were collected from the rice farm and analyzed for ten trace elements by flame atomic absorption spectrometer. The concentrations of the trace elements investigated are as follows: - Ca (76.81), Mg (54.30), Fe (28.2), Cu (4.90), Zn (71.16) and Mn (14.33) mg/Kg. There had been controversial reports about the toxic elements normally present in the rice produced in different areas and conditions. The other four toxic elements As, Co, Pb and Al were also analyzed but not detected. With reference to the literature on the maximum daily intakes for human consumption, the concentration levels were all below the literature except for zinc and manganese

Opis:
Because of waterlogged conditions in rice cultivation, much of the surface-broadcasted urea dissolves in paddy water and is unreachable to the rice crop for this reason. A field experiment was conducted to estimate the influence of urea fertilisation on yield and yield components of hybrid rice ‘Bahar 1’. Three doses (N0, N10, N20 kg N ha-1) of nitrogen from urea sources were foliar-sprayed once at active tillering and booting stages. Grain yield, the number of panicles per unit area, and the number of grains per panicle in the tillering stage of rice were significantly (p < 0.01) increased in a linear fashion when N rates increased from 0 to 20 kg ha-1. The rate of panicle fertility was negatively/positively influenced with increasing N rates in the tillering and booting stages, respectively, indicating the creation of more number of non/partial productive tillers per hill in the vegetative stage than in the reproductive stage. In line with panicle fertility (%), the grain yield was also significantly affected by N treatments with urea fertilisation in the booting stage. Maximum grain yield was obtained with the application of 20 kg N ha-1 at both the tillering and booting stages. Foliar spraying of urea at tillering (20 kg N ha-1) and booting (10 kg N ha-1) stages had a pronounced effect on achieving higher yields as compared to other combinations. The study suggests that foliar application of urea for hybrid rice cultivation might have a potential role in improving nitrogen use efficiency.
Ze względu na podmokłe warunki upraw ryżu, większość powierzchniowej transmisji mocznika rozpuszcza się w wodzie gruntowej i z tego powodu nie jest osiągalna dla uprawy ryżu. Przeprowadzono doświadczenie polowe w celu oszacowania wpływu nawożenia mocznikiem na wydajność i składniki plonu mieszańca ryżu Oryza sativa L. ‘Bahar 1’. Trzy dawki azotu (N0, N10, N20 kg N ha-1), pochodzące z zasobów mocznika, były rozpryskiwane na liście ryżu jednorazowo, przed stadiami krzewienia i tworzenia liścia flagowego. Plon ziarna, liczba wiech na jednostkę powierzchni i liczba ziaren przypadających na wiechę w fazie krzewienia ryżu wzrastały istotnie (p < 0,01) w sposób liniowy, gdy dawki azotu (N) wzrastały od 0 do 20 kg ha-1. Poziom płodności wiechy był odpowiednio uzależniony od wzrostu dawek azotu (N) w stadiach krzewienia i two-rzenia liścia agowego; wskazując na utworzenie większej liczby częściowo nieproduktywnych na wierzchołku źdźbeł w stadium wegetatywnym niż w stadium generatywnym. Z kolei, z płodnością wiech (%), plon ziarna był także istotnie uzależniony od azotu (N) poprzez traktowanie mocznikiem w stadium tworzenia liścia flagowego. Maksymalna wydajność plonu ziarna uzyskano przy aplikacji 20 kg N ha-1 w obydwu stadiach: krzewienia i tworzenia liścia flagowego. Opryskiwanie liści mocznikiem w fazach krzewienia (20 kg N ha-1) i tworzenia liścia flagowego (10 kg N ha-1) miało wyraźny wpływ na uzyskiwanie wyższych plo-nów, w porównaniu z innymi kombinacjami. Badania wskazują, że dolistne zastosowanie mocznika w uprawie mieszańców ryżu może odgrywać potencjalną rolę w poprawie efektywności wykorzystania azotu.

Opis:
This study was carried out in Harrabot village of Tarkughat VDC, Paundi and Majuwa village of Sundarbazar Municipality of Lamjung district during 2015/2016. Thirty households (10 HH from each village) who were involved in seed production were purposively selected for survey. The respondents’ knowledge was gathered through focus group discussions and household surveys, using a pretested semi-structured questionnaire. Seed routine test was carried out in the Agronomy lab of Lamjung Campus. Results revealed that the dominant features of farming in the study areas were small land holdings, fragmented and sloping land with rainfall-dependent farming. Land distribution pattern was 12.93% marginal land, 16.35% upland and 70.72% irrigated lowland. Farmers grew rice, maize, mustard and pulses as major crops and fruits, vegetables, potato and flowers as minor crops. Major cropping pattern were Rice-Mustard-Maize, Maize-Rice-Fallow, Rice-Fallow-Rice etc. Nutrient-poor soils, low pH, farmers' poor access to inorganic fertilizers, soil-depleting cropping patterns, lack of technical knowledge on crop management, soil erosion and degradation are major challenges. Insects, diseases and weeds were major biotic constraints, while lack of irrigation, drought and lack of technical support were major abiotic constraints of rice production. Sukhadhan-2, Sukhadhan-3, Sukhadhan-4, Sukhadhan-5 and Sukhadhan-6 were planted in rain-fed lowland, whereas Ramdhan, Sunaulo sugandha, Loktantra, Sabitri and Makwanpur-1 were grown in irrigated lowland. Seed producers used 39.07% of the land for seed production with 4.78 tons ha-1 of seed productivity. Most of their produced seed was send to Sundar Seed Coop Ltd., Paudibazar, while some seed were stored in their home by using local containers such as earthen pots, plastic drums, metal bins, Dali, Kotho, Bhakari etc. The tested seed quality parameter in the lab showed that the average moisture, purity and germination percentage of the seed samples were 13.87%, 94.13% and 96.72%, respectively.

Opis:
Chromium is a heavy metal; this element is considered as an environmental hazard. Toxicity effects of chromium on growth and development of plants including inhibition of germination process decrease of growth and biomass of plant. The aim of this research is to study accumulation of Chromium along with nutrients and its effect on the growth of Paddy plant (Oryza sativa L). Thus, paddy seedlings grown in petriplates lined with filter paper undergoing, different treatments of Cr (0, 2.5, 5, 10, 25, 50, 75, 100 and 200 mg/L). After one week seedlings were removed and morpho physiological parameters like root length, shoot length and dry weight of plants and Biochemicals ,accumulation of nutrients along with Cr in roots and shoots were determined. The results indicated that the concentrations more than 100 mg/L chromium cause the reduction of morphophysiology parameters in the treatment plants rather than control plant and Cr addition in the cultures caused enhancement of chromium content in roots and shoots of plant seedlings. Similarly the biochemicals and nutrient accumulation also affected by increasing concentrations of chromium. It was also noted that accumulation of chromium in the roots was much higher than the shoots of the seedlings under treatment.

Opis:
Pullulanase (EC 3.2.1.41) in non-germinating seeds was compared with that in germinating seeds. Moreover, pullulanase from the endosperm of rice (Oryza sativa L., cv. Hinohikari) seeds was isolated and its properties investigated. The pI value of pullulanase from seeds after 8 days of germination was almost equal to that from non-germinating seeds, which shows that these two enzymes are the same protein. Therefore, the same pullulanase may play roles in both starch synthesis during ripening and starch degradation during germination in rice seeds. The enzyme was isolated by a procedure that included ammonium sulfate fractionation, DEAE-cellulofine column chromatography, preparative isoelectric focusing, and preparative disc gel electrophoresis. The enzyme was homogeneous by SDS/PAGE. The molecular weight of the enzyme was estimated to be 100 000 based on its mobility on SDS/PAGE and 105 000 based on gel filtration with TSKgel super SW 3000, which showed that it was composed of a single unit. The isoelectric point of the enzyme was 4.7. The enzyme was strongly inhibited by β-cyclodextrin. The enzyme was not activated by thiol reagents such as dithiothreitol, 2-mercaptoethanol or glutathione. The enzyme most preferably hydrolyzed pullulan and liberated only maltotriose. The pullulan hydrolysis was strongly inhibited by the substrate at a concentration higher than 0.1%. The degree of inhibition increased with an increase in the concentration of pullulan. However, the enzyme hydrolyzed amylopectin, soluble starch and β-limit dextrin more rapidly as their concentrations increased. The enzyme exhibited α-glucosyltransfer activity and produced an α-1,6-linked compound of two maltotriose molecules from pullulan.

Opis:
A field experiment was carried out with two varieties of rice (BR 11 and BRRI dhan 31) during Transplanted Aman season of 2018 in K. bearing deep grey terrace soil of Madhupur tract (AEZ 28) under Bangladesh Rice Research Institute (BRRI), Joydebpur. Gazipur. The objective of the study was to know the effect of NPKSZn on the growth and yield of BR 11 and BRRI dhan 31. There were ten treatment combinations with three replications. The treatments were complete (+NPKSZn), reverse complete (-NPKSZn), +N (+PKSZn), -N (+PKSZn), +P (+NKSZn), -P (+NKSZn), +K (+NPSZn) and -K (+NPSZn). The parameters under study were dry matter production, contents and uptake of N, P, K, S and Zn at active and maximum tillering stages, panicle number m’ and grain yield in both the varieties. All the parameters were positively influenced by the treatments under study. Growth and yield of both the varieties were largely affected by the missing nutrient treatment. The highest performance was found with the complete and reverse control treatments whereas the lowest was found with missing element treatments and of course, with control. BR 11 was found to be a better variety than BRRI dhan 31 in respect of yield and yield contributing characters under the treatments. It was also observed that recently fertilized reverse control plot behaved statistically the same as the long term fertilized complete treatment plot. Yield of rice was positively related to K uptake in both the varieties.

Opis:
Lowland sawah farmers often puddle to improve soil hydrophysical conditions for rice, but the puddling intensity beyond which no extra yield increases occur is unknown. Agro- nomic effects of six mechanical puddling intensities were assessed in three Nigerian inland-valley bottoms. All puddled plots, irrespec- tive of intensity, produced similar effects at all three locations. At 10 days after transplanting, soil bulk density of all puddled plots re- presented mean decreases relative to control plots of about 22.4, 15.8, and 31.7% at Akaeze, Adani, and Ejeti, respectively. Soil bulk density and moisture content upon saturation were similar during 40-120 days after transplanting. All puddled plots consistently showed taller plants and greater tillering than control plots only at Ejeti. Grain yields were similar among treatments in Akaeze and Adani (mean, 3.71 and 6.42 Mg ha -1 , respectively), but one-pass puddling yielded numerically highest in both locations. At Ejeti, grain yields followed the trend for plant growth, with mean values of 4.36 and 1.81 Mg ha -1 for puddled and control plots, respecti- vely. One-pass puddling may be sufficient for sawah rice grown late particularly in less humid environments.

Opis:
A study was conducted at the Department of Horticulture, KNUST, Kumasi from June to November, 2015 with the objectives to (i) determine the rate of ATONIK plant growth regulator (PGR) suitable for high yield of two varieties of hybrid rice (ii) determine the combined effects of PGR rates and varieties on the growth and yield performance of hybrid rice. A 2 x 5 factorial arrangement in randomized complete block design with three replications was used. The factors were varieties at two levels: Agra Rice and Jasmine 85 and PGR at five levels: ATONIK at 450 ml/ha, ATONIK at 500 ml/ha, ATONIK at 550 ml/ha, ATONIK at 0 ml/ha and GA3 at 60 ml/ha. Comparing the ATONIK rates with the GA3, ATONIK at 450 ml/ha resulted in a 14.3 % increase in the number of rice panicles. Application of ATONIK at 450 ml/ha, 500 ml/ha and 550 ml/ha resulted in 14.4%, 10.7% and 4.4% higher percentage of productive tillers, respectively, than that produced by GA3 at 60 ml/ha. ATONIK at 450 ml/ha application led to a 17.8 % increase in grain yield. For the harvest index, application of ATONIK at 450 ml/ha resulted in the highest harvest index of 45 %, significantly greater than the other PGR treatments. In conclusion, the study clearly demonstrated that ATONIK PGR was superior to GA3 in the vegetative and productive performance of rice. The most suitable rate of ATONIK for increased rice productivity was 450 ml/ha.

Opis:
A pot culture was carried out with Oryza sativa L. vari-Co-39, to investigate the effects of supplementary calcium chloride on plants grown at NaCl (50mM) concentration. Treatments were: (1) Control: nutrient solution alone (C); (2) nutrient solution plus 50mM sodium chloride (NaCl); (3) nutrient solution plus 10mM calcium chloride (CaCl2); (4) nutrient solution plus 15mM calcium chloride (CaCl2); (5) nutrient solution and 50 mM NaCl plus supplementary 10 mM CaCl2 (NaCl + CaCl2); and (6) 50 mM NaCl plus additional mixture of 15 mM CaCl2 in nutrient solution (NaCl + CaCl2). The plants grown under salt stress produced low dry weight and relative water content than those grown in standard nutrient solution and in CaCl2 alone. Supplemental calcium chloride added to nutrient solution containing salt significantly improved growth and relative water content. Membrane permeability increased with high NaCl application and these increases in root membrane permeability were decreased with supplementary Ca. The concentration of chloride (Cl) increases highly for all treatments. Sodium (Na) concentration in plant tissues increased in both shoots and roots at high NaCl treatment. Application of supplementary Ca lowered Na concentration. Concentrations of Ca. K and N were at deficient ranges in the plants grown at high NaCl levels and these deficiencies were corrected by supplementary Ca. The ameliorating effect of Ca on growth and physiological variables could reduce the negative effect of salinity of Oryza sativa L., plants.

The use of plant growth promoting rhizobacteria is increasing in agriculture and gives an appealing manner to replace chemical fertilizers, pesticides, and dietary supplements. Th e objective of our research was to access the plant growth promotion traits of Pseudomonas aeruginosa, P. fl uorescens and Bacillus subtilis isolated from the maize (Zea mays L.) rhizosphere. In vitro studies showed that isolates have the potential to produce indole acetic acid (IAA), hydrogen cyanide, phosphate solubilisation, and siderophore. RNA analysis revealed that two isolates were 97% identical to P. aeruginosa strain DSM 50071 and P. aeruginosa strain NBRC 12689 (AK20 and AK31), while two others were 98% identical to P. fl uorescens strain ATCC 13525, P. fl uorescens strain IAM 12022 (AK18 and AK45) and one other was 99% identical to B. subtilis strain NCDO 1769 (AK38). Our gnotobiotic study showed signifi cant diff erences in plant growth variables under control and inoculated conditions. In the present research, it was observed that the isolated strains had good plant growth promoting eff ects on rice.
