摘要

Field experiments were conducted at IAR! farm for four rabi season in the years 2000-01 to 2003-04 to study the influence of nitrogen fortified crop residue compost on the grain and straw yield and total uptake of micronutrients viz., Zn, Cu, Mn and Fe by wheat and their available status in soil at harvest. Nitrogen was supplied @ 120 kg/ha from N-fortified crop residue compost or urea or both in combinations in three ratios 4:1, 3:2 and 1:1. The grain yield in various N treatments increased from 45.6 to 106.1 per cent over control during the four years. The maximum grain yield (44.9 to 60.8 q/ha) was noticed with the combined application of N through fortified compost and urea in 1:1 ratio in all the four years. Among all the N treatments, 1:1 ratio had maximum total uptake of micro nutrients which showed an increase from 21.8 to 33.3 % for Cu, 23.0 to 27.9 % for Zn, 5.2 to 10.7 % for Fe and 2.3 to 10.5 % for Mn over the treatment where N was applied through urea alone in all four years of experimentation. The treatments comprised of compost alone and its combinations with urea i.e. 4:1 and 3:2 were intermediate in effect in relation to grain yield and uptake of micronutrients. Moreover, increasing proportion of N through compost from 50 to 100%resulted in proportionate increase in the build up of available micronutrients in soil.
