Increasing Lemongrass Herb Yield and Quality Through Nitrogen Addition

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...

Sugarbeet Yield and Quality as Affected by Nitrogen Level

Thii study was conducted, under several climatic and soil conditions, to determine the effect of N level on beet yield and quality and to further develop and me both soil and tissue test methods for predicting N fertilizer needs for efficient refined sucrose production. Previous studies indicate that N fertilizer needs for =Wm= sucrose production may be predicted by con. sidering yieldpotential...

Nitrogen Nutrition in Relation to Yield and Quality of Grapefruit.

Investigations at this and other stations have shown generally that nitrogenous fertilizers exert considerable influence in increasing the yields of grapefruit and other citrus fruits. The factors affecting quality of grapefruit and the relation of nitrogen nutrition to quality have not yet been fully studied with the result that orchard management practices, particularly in Arizona, cannot be ...

Influences of irrigation interval,nitrogen fertilization and plant spacing on tomato fruit yield and quality

Nitrogen Addition Regulates Soil Nematode Community Composition through Ammonium Suppression

Nitrogen (N) enrichment resulting from anthropogenic activities has greatly changed the composition and functioning of soil communities. Nematodes are one of the most abundant and diverse groups of soil organisms, and they occupy key trophic positions in the soil detritus food web. Nematodes have therefore been proposed as useful indicators for shifts in soil ecosystem functioning under N enric...
