effect of planting date on dry matter and yield components in four soybean cultivars

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...

Effect of Planting Date on Population Densities of Hoplolaimus columbus and Yield of Soybean.

During the 1991 and 1992 soybean growing seasons, field plots were established in South Carolina to study the effect of planting date on at-planting nematode densities and subsequent yield losses caused by Hoplolaimus columbus. The susceptible and intolerant soybean cv. Braxton was planted on five dates from to May to 28 June in 1991 and from 12 May to 28 June in 1992. Nematodes were recovered ...

Effect of sowing date on seed yield and yield components of canola (Brassica napus L.) cultivars in north Khuzestan conditions

Determination of optimum sowing date plays an important role in crop management and achieving the higher yield. To study the effectof sowing date on seed yield of canola cultivars, a filed experiment was carried out as strip split plot block arrangement in randomized completed block design with three replications in 2017-18 and 2018-19 cropping seasons at Safiabad Agricultural and Natural Resou...

investigation of leaf area index, dry matter and crop growth rate on the yield and yield components of soybean cultivars

yield in most crops is resulted from a number of physiological processes which occurred during plant growth and development. these processes are realized at morphological, pheonological and physiological levels and often are controllded by many genes. in order to determine the effective of physiological traits onseed yield of soybean (glycine max l.) cultivars and their relationship with yield ...
