in order to determine the optimum planting date under deficit output area, this research was carried-out in 2010-11 and 2011-12 cropping seasons, in split-plot arrangement, using complete randomized block design with three replications in khuzestan agriculture and natural resource research center. main and sub plots were consisted of four planting dates (oct. 27 with 10 days interval) and four ...

in order to study yield and yield components in intercropping bean (phaseolus vulgaris l.) and sweet basil (ocimum basilicum l.) and evaluating effect of intercropping on weed control, a field experiment was conducted at the agricultural research station, ferdowsi university of mashhad during growing season of 2008. treatments: included 1- sole crop of bean 2- sole crop of sweet basil 3- strip ...

a trial study was carried out to assess the influence of the plant residue management in conjuction with application of different nitrogen sources on wheat yield and components, at the agricultural faculty of shahidchamran university of ahvaz during 2011-2012.the experimental design was splitplot at randomized completed block design arrangement. the main plot were different wheat residue manage...

Three maize hybrids (Baber, Pioneer 30P45 and Syngenta 6621) were compared for yield and yield components and correlations were worked out among the yield parameters at various nitrogen levels in an experiment conducted at Agricultural University, Peshawar, Pakistan during summer 2009. The experiment was laid out in randomized complete blocks with split plot arrangement having three replication...

Trait-based breeding is essential to improve wheat yield, particularly when stress adaptation is targeted. A set of modern and underutilized wheat genotypes was examined in a 2-year field experiment with distinct seasonal water supply. Yield formation and drought response strategies were analyzed in relation to components of Passioura's yield-water framework based on phenological, morphological...

considering the importance of medicinal plants growth and biological application of fertilizers with sustainable agricultural production in order to eliminate or reduce chemical input to achieve desirable and sustainable quality, an experimental research was  conducted based on a randomized complete block design with two factors of chemical nitrogen (46% urea nitrogen) at  two levels (zero, 25 ...

Chickpea (Cicer arietinum L.) is a native crop of Asia which is grown worldwide including Iran.In this study,different selection criteria including correlation,regression and path analysis were used to improve yield.The experimental design was split plot with RCBD replicated four times in which three sowing dates (5 January,4 February,and 5 March) were used in main plots and four genotypes;two ...
