GROWTH, YIELD ATTRIBUTES, YIELD AND NET RETURNS OF WHEAT (TRITICUM AESTIVUM. I.,) AS INFLUENCED BY SOIL APPLIED FYM, GYPSUM AND IRON PYRITE UNDER IRRIGATION WITH POOR QUALITY WATER

摘要

A field experiment was conducted for evaluating the response of wheat to soil applied farmyard manure, gypsum and iron pyrite. The soil applied farmyard manure showed the significant increase in plant height, total tillers, test weight and net returnsupto 201FYM ha~(-1) and effective tillers, grain and straw yield upto 30 t FYM ha~(-1). The substantial improvement in plant height, total tillers, effective tillers, test weight, grain and straw yield and net returns observed under 50% GR either applied through gypsum or through pyrite except that total number of tillers and net returns, in case of pyrite application increased significantly upto 25% GR through pyrite. The combined application of 20t FYM and gypsum 50% GR recorded significantly highernumber of effective tillers and grain and straw yield of wheat and net returns as compared to other treatments. The number of effective tillers and grain and straw yield of wheat increased significantly under combined application of 30 t FYM + pyrite 25%GR but the net returns recorded significantly highest under 20t FYM + pyrite 25% GR.
