The present study aimed at investigating the effect of different levels of nitrogen on yield and yield components of bread and durum wheat. To this end the experiment was conducted in 2010-2011 in south west of Iran as split plots based on randomized complete block design with three replications. Main plot included four levels of nitrogen 60, 120, 180, 240 kg.ha-1 and the sub plot included four...

Wheat starch development is a complex process and is markedly difference by changes in spikelet spatial position. The present study deals with endosperm starch granule distribution and spatial position during filling development. The study was conducted with pure starch isolated from wheat (Triticum aestivum L.), Jimai20 and Shannong1391, at 7-35 days after anthesis (DAA). The results showed th...

Mycorrhizal fungi can be integrated in soil management to achieve low-cost sustainable agricultural systems. Hence, the effects of non-using (M1) and using (M2) of mycorrhizal fungi on reduction of phosphate fertilizer consumption, growth and yield of maize under different levels of phosphate fertilizer (P1: zero, P2: 20, P3: 40, P4: 60, P5: 80 and P6: 100% recommended) were investigated in a f...

Objective: In order to study the effect of solopotasse fertilizer on yield and essential oil of cumin medicinal plant. Methods: A experiment in randomized complete block design with three replications conducted in kermam city, Iran, in 2013. solopotasse fertilizer in four levels (0, 50, 100 and 150 kg/h) investigated. Plant height, number of umbrella per plant, number of seed per umbrella, 1000...

     To estimate heritability and association between traits traits, 148 recombinant inbred lines and their parents (Yecora Rojo and No. 49) were evaluated in Alfa lattice design with two replications under normal and water deficit conditions during two cropping season (2013-15). Results showed that there were significant differences between genotypes for all studied traits. The estimated herit...
