Abstract
A field experiment was conducted during the rainy seasons (kharif) of 2002 and 2003 at the Research Farm of the institute at Varanasi to study the effect of superimposition of fortified and unfortified rice-straw compost Q 6 tl ha over recommended NPK (120 kg N, 60 kg P,O, 60 kg K,O/ha) on growth, yield and nutrient uptake by rice (Oryza sativa L.). Among the different cellulo-azoto-bacterio compost treatments, rice-straw compost @ 6 tlha in- oculated with Azotobacter + phosphous solublizing bacteria (PSB) along with NPK registered significantly higher plant height, leaf-area index and yield attributes (panicles, panicle length, grainslpanicle and test weight), and gave 21.17% increase in grain and 15.36% in straw yields compared with NPK (120 kg N, 60 kg P,O, 60 kg K,O/ha). This treatment also gave the highest net returns (Rs 18,946lha). Application of rice-straw compost inocu- lated with cellulolytic fungi + Azotobacter + PSB along with NPK was also equally effective as rice-straw compost inocluated with Azotobacter + PSB (cellulo-azoto-bacterio compost) along with NPK in terms of leaf-area index, number of panicles, grainslpanicle, test weight and K uptake by rice. Fortified compost with Azotoacter and PSB + NPK also maintained soil fertility, as indicated by higher contents of organic carbon, available nitrogen, phos- phorus and potassium. However, values of these parameters showed declining trend with recommended level of NPK (control).
