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...

An experiment was conducted to study the effects of inclusion of a wheat cultivar (high in nonstarch polysaccharides) and xylanase supplementation of the diet on productive performance, pH of the gastrointestinal tract, nutrient retention, and intestinal enzyme activity of Hy-Line W-36 laying hens from 25 to 47 wk of age. The experiment was completely randomized with 8 treatments arranged facto...

a field experiment was performed in order to evaluate the effects of irrigation and application of k fertilizer on seed storage proteins  in chickpea, ilc-482 cultivar. experiment was performed in factorial using randomized complete block design with three replications. in this experiment, two factor consist of irrigation in three levels (i1= non irrigation and i2= irrigation in flowering stage...

Cotton (Gossypium hirsutum L.) and potassium (K) dynamics are not well understood particularly in soils with high K levels. Potassium is important for cotton reproductive development as it influences the number, size, weight of bolls can improve fiber quality by mitigating moisture stress. In case that soil cannot replenish solution from exchangeable reserves to meet plant demands, deficiencies...

Maize (Zea mays L.) is an important crop among Brazilian smallholder farmers,who are also responsible for 40% of the poultry and egg production in the country.Although poultry litter is considered a potential pollutant, if properly stabilized anddistributed in the field it can be used as a source of nitrogen for maize production.In this study, the response of maize to mineral fertilizer and pou...

babol local lettuce as a landrace in mazandaran, has cultivated for many years. local lettuce is a mixture of different genotypic and phenotypic forms which affects its marketability. it was purified by individual selection method during a three year priod (1998-2000) based on the selection for characteristics such as shape of bush, closed pome high yield, good marketability and resistance to d...
