To survey the effects of flooding during the reproductive growth stages of aerenchyma formation and ethylene production in soybean cultivar DPX experiment  the completely randomized factorial was in 2012 in Gorgan University of Agricultural Sciences and Natural Resources. Factors examined include nutrition levels in three levels (1 - inoculated with bacteria JaponicumBradyRhizobium 2 - non-inoc...

abstract in order to investigate the effects of nitrogen fertilizer levels on the yield and quality of potato, (solanum tuberosum l.) a field experiment was conducted based on randomized complete blocks design with 3 replications in the research field of the college of agriculture, ferdowsi university of mashhad. nitrogen topdress fertilizer was applied in two levels of 100 and 150 kgn.ha-1 and...

A nematicide, dibromochloropropane; the fungicides benomyl and maneb; an insecticide, oxydisulfoton; the herbicides trifluralin, linuron, and dinoseb; and fertilizers were applied to Heterodera glycines-infested soil. A resistant soybean cultivar alone produced the highest yield in one test, and its yield was not affected by application of pesticides or fertilizer. In two tests the cultivar tha...

a factorial experiment based on a randomized complete block design with three replications was carried out in order to study the effects of tuber size, nitrogen fertilizer and harvest date on yield and yield components of potato. this experiment was conducted in a grower’s farm in uraki village located in chabahar city, in 2011. in this experiment, the treatments were two levels of tuber size (...

The present study was carried out on one year -old two olive cultivars, Coronaiki as oil cultivar and Manzanillo as double purpose (table and oil) cv. in a private farm located at western desert along Cairo, Alexandria Road (50 km from Cairo), Egypt and planted at 5 x 6 meter apart in sandy soil and irrigated with drip irrigation system trees were similar in growth vigour and received the commo...

individual grain weight of wheat kernels differs with their positions on a spike. cultivation practices (such as fertilizer nitrogen and plant growth regulators application) can be used to improve weight of basal and distal kernels. for this purpose, two experiments based on randomized complete block design were carried out with three replications. the aim of this research was to study the mech...
