dc.description.abstractThe present investigation was undertaken to explore the possibilities of economising fertilizer nitrogen without saerifying crop yields from tne crop sequences which included legumes. The trends in cropping system for last few years indicated the stability of high production, due to the use of advanced technology and economic gains in the components crops in system. The present study was conducted to study the effect of different cropping sequences and fertilizer levels over the years at the termination of the long term experiment during the year 1993-94. Soil samples before sowing and after harvest of each crop were collected and analysed for the chemical properties to monitor changes in soil fertility and also to study the changes in physical properties of soil. Nutrient removal by various crops in sequences during kharif and rabi season were studied. The investigation carried out indicated that when legumes were included in system, they leave considerable, favourable, residual effects on succeeding cereal crops. Similarly green manuring also showed posi-Live, direct and residual effect on succeeding cereal crops. From the system productivity point of view, it is evident that legumes can compete and replace cereal crops in long term rotation. Results showed that groundnut can replace pearlmillet in pearlmillet-wheat system. The inclusion of green manure in cereal-cereal system in all the treatments resulted in enhanced productivity and 25 per cent saving in fertilizers with 11 per cent more grain yield of wheat in pearlmillet-wheat-green manuring system (T,). The direct effect of green manuring in kharif crop was about 9 per cent in pearlmillet. The highest gross and net monetary returns were obtained from groundnut-wheat-fallow systems. Benefit cost ratio indicated that if wheat is grown after groundnut, saving of 25 per cent recommended fertiliEer dose is - possible. Groundnut-wheat system also showed more sustainability index over the years than other sequences tried. No appreciable changes on physical properties were noticed. The positive balance of available and total soil nitrogen was observed at all fertilizer levels in crop sequences where preceding or succeeding crop when legume or green manuring in fixed crop rotation was followed. Considering the production, economics and soil health, the adoption of legume-cereal or inclusion of green manuring in crop sequence, 75 per cent recommended fertilizer dose to cereal crops were found to be remunerative and beneficial over cereal-cereal rotations.en_US
