Abstract

A field experiment was conducted to study the effect of different organic manures
(compost, vermicompost, farmyard manure, subabul and sunhemp) with different doses of
fertilizer N (50% RDN and 100%) RDN) on yield (grain, straw) and uptake of micronutrients
(Zn, Cu, Mn and Fe) on deep black soils of Vertisol. The chickpea yield and uptake of
micronutrients increased significantly with 50% nitrogen through subabul plus 50%
recommended dose of nitrogen. Moreover, application of N along with organic manures
showed additive effect on these parameters. With the treatments involving combination of
organics and inorganics, yield and nutrient uptake were invariably higher than with the
recommended dose of N. The effect of different organic manures in combination with
fertilizer N on chickpea yields and nutrient uptake were rated as: subabul> sunhemp>
compost> FYM> vermicompost. The highest yield of grain (666.54 kg ha-1), straw (1152.13
kg ha-1) were obtained where 50% N through subabul( as green manure) plus 50% of
recommended dose of fertilizer N. The uptake of Zn, Cu, Mn, and Fe was highest by chickpea
(grain and straw) where 50% N through subabul and 50% RDN as integrated treatment
