Effect of Slag Based Gypsum on Nutrient Uptake and Yield of Rice (Oryza sativa L.) in an Alkaline Soil

effect of seed priming and irrigation regimes on yield,yield components and quality of safflowers cultivars

این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...

Integrated nutrient management and LCC based nitrogen management on soil fertility and yield of rice (Oryza Sativa L.)

The experiment was conducted at lowland series of wet lands, International Rice Research Institute (IRRI) Farm, Los Banos, Laguna, Philippines. The rice variety PSBRc 82 was raised during wet season (June – October), and the experiment was laid out in randomized block design with four replications. There were eleven treatments viz., control, recommended NPK fertilizer, -N, -P, -K, LCC 3, LCC 4,...

The Role of Selenium in Soil: Effect on the uptake and Translocation of Arsenic in Rice (Oryza sativa L.)

The contamination of paddy soils by arsenic (As) is a serious problem in rice production areas across the world. This study investigates the effect selenium (Se) has on the formation of iron plaques on the outside of rice roots and the accumulation of As in rice plants. A soil combined sand pot experiment having four concentrations of Se (0, 1, 5 and 10 mg kg -1 ) and two concentrations of As (...

Iron Bioavailability and Arsenic Uptake in Rice (Oryza sativa L.)

EFFECT OF TIDAL SUBMERGENCE ON POTASSIUM NUTRITION AND YIELD OF RICE (Oryza sativa L.) M.A. HAQUE

Field experiments were conducted at Patuakhali Science and Technology University research farm during 2009 T. Aman season to investigate the effect of tidal submergence on potassium nutrition and yield of rice. The experiment included two levels of irrigation water sourcei) tidal water and ii) ground water, and three levels of fertilizersi) absolute control (no fertilizer), ii) NP (K omission),...
