Production potential and nutrient uptake of wheat (Triticum aestivum) as affected by organic sources of nutrients and micronutrients

Abstract

A field experiment was conducted during rabi season of 2005-06 and 2006-07 to study the effect of micronutrients and FYM on growth, yield and nutrient uptake by wheat (Triticum aestivum L.) in Gangetic alluvial soil of Uttar Pradesh. The experiment was laid out in split plot design with three replications. Wheat crop recorded significantly higher value of growth, yield attributes (effective tillers/m2, spike length, grains/spike and 1 000 grain weight), yields, benefit: cost ratio and nutrient accumulation under integrated source of nutrients than inorganic fertilizer alone. Maximum grain yield (4.45 tonnes/ha) was recorded with Zn @ 5 kg/ha + FYM @ 10 tonnes/ha + RFD, which was about 36.01% more than the grain yield obtained from application of 2.5 kg Zn /ha + recommended fertilizer dose. There was significant improvement in yield attributes, yields and nutrient uptake due to foliar treatment of micronutrients (Fe and Mn).
