Abstract
The experiment was conducted during kharif and summer season of the years 2014-15 and 2015-16 in Net house, Department of Soil Science and Agricultural Chemistry, B.A. College of Agriculture, Anand Agricultural University, Anand, Gujarat. The present investigation was under taken to study the “Comparative evaluation of manurial qualities of water hyacinth compost on yield and chemical composition of Wheat (Triticum aestivum L.) and its residual effect on fodder sorghum (Sorghum bicolor L.)”. The experiment was laid out in completely randomized design with twenty treatments of water hyacinth composts, FYM and vermicompost

combinations of RDF with and without zinc and multi-micronutrient mixture grade-V (MMMG-V) which were replicated three times.
Application of RDF + Water hyacinth compost with saw dust @ 5 t ha-1 + Zn @ 5 ppm increase grain (20.82 g pot-1), straw (23.48 g pot-1) and total yield (44.30 g pot-1), which was at par with application of RDF + Water hyacinth compost with saw dust @ 5 t ha-1 + MMMG-V @ 25 kg ha-1, RDF + Water hyacinth compost @ 5 t ha-1 + Zn @ 5 ppm and RDF + FYM @ 10 t ha-1 + Zn @ 5 ppm, these four treatments clearly indicated that the efficiency of water hyacinth composts with and without saw dust in combination with 5 ppm Zn and recommended dose of fertilizers was proved as good as FYM 10t ha-1 with Zn and recommended dose of fertilizers, it could also be inferred that treatments comprised of water hyacinth composts, FYM, Zn and MMMG-V gave response, this could be because of deficient level of available zinc and lower organic carbon content of the soil.
The highest fodder sorghum green (194.5 g pot-1) and dry (44.73 g pot-1) matter yield were recorded under RDF + Water hyacinth compost with saw dust @ 5 t ha-1 + MMMG-V @ 25 kg ha-1, Due to the decomposition of organic manure, an additional nitrogen as and micronutrients added to the soil which could have increased the green and dry matter yield of fodder sorghum. So, water hyacinth composts and FYM application showed residual effects on the green dry matter yield of sorghum while vermicompost application did not show residual effect on the sorghum dry matter yield.
