Résumé partiel
The physico-chemical and biological properties of soil and yield, quality and nutrient content and uptake by different crops as affected by FYM (0 and 10 t ha-1) and fertility levels [no fertilizer (FL1), 50% (FL2), 100% (FL3) and 150%o (FL4) of the recommended NP] in a pearlmillet-mustard-cowpea (fodder) sequence were evaluated during 1998-1999 and 1999-2000 from a long term experiment being conducted since 1994 at the Micronutrient Project (ICAR), G.A.U.. Anand. Soil samples at different depths of profile (0-15 cm) (D1), 15-30 cm (D2), 30-45 cm (D3), 45-60 cm (D4), 60-75 cm (D5) and 75-90 cm (D6) were collected in 2000 summer after harvest of cowpea (fodder). EFFECT OF FYM Application of FYM @ 10 t ha-1 to kharif pearlmillet had decreased bulk density and increased water holding capacity of soil. Its supplementation also improved availability of total N, P, K, S, Mn and Zn due to increase in organic carbon content of soil in the upper horizon (upto 30 cm). The DTPAextractable Fe in soil at 15-30 cm depth was in a deficient range (<5 mg kg-1). The total microbial biomass carbon and microbial population were improved by about 43, and 8.8 per cent, respectively. The overall increase in seed, straw and total yield of pealmillet was about 42 per cent due to FYM application. The total uptake of all the nutrients was higher under FYM than no FYM. The oil and protein contents of pearlmillet seeds were increased by 6.2 and 12.6 per cent, due to FYM addition, respectively. The increase in seed and straw yields of mustard was to the extent of 16.2 and 6.6 per cent due to FYM over no FYM, respectively.
