Abstract

Daily rainfall data of 29 years (1981-2009) recorded at RVSKVV, Zonal Agricultural Research Station Morena, Madhya Pradesh was examined for long term averages of annual, seasonal, monthly, and weekly rainfall and its temporal variability. Co-efficient of variation of 27.1 per cent indicated that the annual rainfall was more or less stable over the years. The season-wise per cent contribution of annual rainfall was 3.7, 7.9 and 88.4 per cent of summer, Rabi and Kharif seasons, respectively. With in the rainy season, August was the highest rainfall contributing month (33.4%) followed by July (28.9%) mean weakly, precipitation amount and its assurance reaches the peak (>50mm/week) during 26th SMW (Standard Meteorological Week) to 38th SMW and again declined thereafter. The earliest onset of rainy season occurred in 24th SMW. The normal onset of rainy season was observed as 26th SMW with CV of 5.8 per cent. There is an ample scope for rain water harvesting from July to September which can be utilized as crop saving irrigation as well as pre-sowing irrigation for succeeding Rabi crops which are generally sown on residual soil moisture

Abstract

Field experiments on Happy seeder were conducted during 2009-10 and 2010-11 in farmer participatory research mode at different locations in the district Fatehgarh Sahib. The field experiments were conducted on 9 different locations to evaluate the operational performance of Happy seeder machine in context of heavy soils of district Fatehgarh Sahib, the effect of Happy seeder on wheat yield in heavy soils and to work out the economics of Happy Seeder as compared to farmer's practice. The study reveled that, the average reduction in weed count in happy seeder plots was 28% compared to conventional sown wheat. Wheat yield during these two years in 9 experiments was varied from 35.0 - 56.25 q/ha and 31.75 - 50.75 q/ha for Happy seeder and conventional seed drill plots, respectively with an average increase in yield of 8.84 % in Happy seeder plots.
