pepper is one of the nutrition demanding vegetable. in order to compare n fertilizer uptake and plant numbers per area unit, an experiment was conducted with replications. in which fertilizer was the main factor and included ammonium nitrate in 7 levels (0, 80, 160, 240 kg /ha-1) and 40+40, 80+80, 120+120 kg/ha-1 (in 2 stages i.e. half of these amounts appliedpre planting and the other half of ...

abstract the quantative and qualitative yield comparison of three cucumber f1 cultivars including' sina, amyral, and negin was evaluated using 3×3×3 factorial experimental design with six replication. three types of pruning treatments were applied; cutting down all branches on main stem (b1), leaving one node and the leaf next to it on all branches (b2), leaving two node and the leaf next to th...

this study was conducted to evaluate the effect of fertilizers on the yield and essential oils of basil. this experiment was carried out in completely randomized block design with three replications in jiroft area. the treatments included three levels of barvar 2 (10, 20 and 25 g/ha), cow manure at three levels (5, 10 and 15 ton/ha), ammonium phosphate and superphosphate triple each at three le...

Nitrogen use efficiency is important for the development of sustainable agriculture. Plants have different transporters to facilitate nitrogen uptake and internal distribution. This study demonstrates that the peptide transporter OsNPF7.3 enhances nitrogen allocation and increases grain yield in rice. OsNPF7.3 is a member of the nitrate transporter 1/peptide transporter family (NPF) and is loca...

to study the including rhizobium treatment (strain numbers of 133, 116 & combination of them) along with 100% nitrogen fertilizer application and a check (no inoculation & no fertilizer) on certain agronomical and physiological traits of three common bean cultivars (viz. bahman, darkhshan & sayiad) a field experiment was performed at research station of university of tehran (karaj-iran) in 2010...

twenty-two bread wheat cultivars along with susceptible (sholeh) and resistant (azadi) control cultivars were evaluated for resistance to russian wheat aphid of two growth stages including seedling and stem elongation in greenhouse. five adult aphids per plant were used for infestation. leaf chlorosis at seedling and stem elongation stages and leaf rolling at seedling stage were measured. other...
