Abstract/Description: | Towards Small Farm Mechanization... Bullock power and human labour are rapidly dwindling affecting agriculture. Farmers are unable to carry out timely agricultural operations which is critical factor for good yields in rainfed agriculture. High temperatures during the sowing and weeding time are reducing the human efficiency resulting in poor performance on the field. MGNREGA is also negatively impacting agricultural operations. Resource poor rainfed farmers are further marginalized because of this as they can hire labour at high market rates. In many crops the cost of labour has risen 40-55 % of the total cost of cultivation from 10-15% two decades ago. The erratic rainfall is also reducing the sowing window and other agricultural operations, especially intercultivation and weeding. Hence, farm mechanization has become an urgent need in rainfed agriculture. CRIDA evolved several mechanization options for rainfed agriculture. The introduction of seed cum fertilizer drill itself increased the yields by 15% due to timeliness and precision, apart from saving seed and fertilizers. Recently, CRIDA has developed Ridger-planter for effective in-situ moisture conservation right from sowing time. The zero-till planter with slit opening and individually operated shanks would work in uneven lands as well. Herbicide attachment with this planter further takes care of the existing weeds with post emergence herbicides and initial flush of weeds with pre-emergence herbicides in zero-tillage conditions. If properly planned, the cost of cultivation can be reduced by 35-40 % by using farm machinery in major agricultural operations apart from reducing the drudgery and other management stress in agriculture. The usage of low lift and low energy water pumps for critical irrigation from farm ponds helped many farmers to combat Contd... Pg. 2 CRIDA - News Letter 2 RESEARCH HIGHLIGHTS A New Tool for Climate Vulnerability Assessment Impact of extreme climate events like drought, heat-wave, flood, frost, cold-wave, gale, cyclones, etc., on the earth and ecosystem can be discerned by tools and techniques of Remote Sensing. Changes in land use/ land cover and vegetation growth and vigor can be used as proxy for vulnerability assessment with changes in Normalized Difference Vegetation Index (NDVI) as indicator for understanding these processes. NDVI from Advanced Very High Resolution Radiometer (AVHRR) 8-km data and from Moderate Resolution Imaging Spectroradiometer (MODIS) 16-day 250m NDVI data product were taken to analyze vulnerability of Indian agriculture to climate change under NICRA project. Temporal analysis of NOAA-AVHRR- NDVI product and MODISTERRA NDVI datasets downloaded from their respective websites, were used for analyzing agricultural vulnerability in India. While the Global Inventory Modeling and Mapping Studies (GIMMS) data set of NOAA- AVHRR (8 km resolution) was used to analyse vulnerability at State- and Agro-eco-sub-region (AESR) level during 1982 - 2006 period (Figure 1), MODIS (16 -day 250m resolution) NDVI data product was used to Fig. 1 : CV of Max NDVI across AESR in India drought and increased yields in several districts of Andhra Pradesh. However, the cost of farm implements discourages small and medium farmers to opt for mechanization. Hence it is necessary to open custom hiring service centers at block/mandal level in a big way so that farmers can get the service at minimum rental cost. These hiring centers should be supported technically by the skilled technicians in all parts for effective functioning. Million of matriculates across the country can be trained under the national skill development mission to be initiated in XII Plan and provided financial assistance to open custom hiring centers. This will be a win-win situation wherein unemployed youth get self employed and labour shortage for farmers is also addressed. Dr. B. VENKATESWARLU Director, CRIDA |
