simulation of rice water productivity via cropsyst model under low irrigation and nitrogen fertilizer
introduction water consumption improvement in agriculture is very important compare with other sections. because of existing complexity in production and exploitation processes and optimized application of irrigation water and nitrogen especially in dry and semi-dry areas facing with water constraint is an important goal in this field. yield gap analysis can help to identify how much yield incr...
متن کاملYield and nitrogen leaching in maize field under different nitrogen rates and partial root drying irrigation
Irrigation water is limiting for crop production in arid and semi-arid areas. Furthermore, excess nitrogen (N) application is a source of groundwater contamination. Partial root drying irrigation (PRD) can be used as water saving technique and a controlling measure of groundwater N contamination. The objectives of this investigation were to evaluate the effect of ordinary furrow irrigation (OFI...
متن کاملeffect 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...
Safflower model for simulation of growth and yield under various irrigation strategies, planting methods and nitrogen fertilization
Development and use of crop growth models is an effective tool for agricultural planningand decision making in agricultural industry. Besides, the drought and limited supplies of waterin many areas of the world has increased attention to favourable strategies in farm managementsuch as efficient irrigation and planting methods. The objective of this study was to develop acrop model for safflower...
متن کاملAssessment of the AquaCrop Model for simulating Canola under different irrigation managements in a semiarid area
Field experiments were conducted in 2005-2006 and 2007-2008 and the data were used tocalibrate and validate yield and biomass of AquaCrop Model for canola (Brassica napus l.). Themodel was calibrated with the first year and then was validated with the second year data. Fivewater stress treatments at different growth stages were performed including fully irrigatedduring whole growing period (I1)...
