The study highlights the performance of different shelling machines used in Kokan region of Maharashtra. The effect of cashew nut size on performance of cashew nut shelling machines and there comparative differences between three shelling machines were studied. It was found that, the size of cashew nut had significant effect on the shelling efficiency of machine. The per cent shelling efficiency of the machine increased with increase in size of cashew nut. The manual operated shelling machine showed higher shelling efficiency as compared to traditional and improved power operated shelling machine. It is also observed that the improved power operated machine had lower uncut, breakage, higher whole kernel recovery and cashew nut picking efficiency as compared with traditional power operated and manual shelling machine. Operating cost of manual, traditional and improved power operated cashew nut shelling machine were 7, 3.12 and 2.31 Rs./kg, respectively. Operating cost of improved shelling machine was 66 per cent and 57.4 per cent higher as compared to manual and traditional power operated shelling machine, respectively. Improved power operated shelling machine saved monthly Rs. 21138/- as compared to manually operate shelling machine.Keywords

This study highlights the energy consumption pattern of paddy cultivation practices followed in Kokan region of Maharashtra. The study data were collected from eight regional research stations of Balasaheb Sawant Kokan KrishiVidyapeeth, Dapoli. The net energy, specific energy, energy output input ratio,energy productivity and water productivity for paddy cultivation was found to be 61738.52 MJ/ha, 0.86 MJ/kg, 2.22, 1.16 kg/MJ and 9.33 kg/m3, respectively. The cost per energy input and cost per energy output was found to be 19.99 Rs./MJ, 0.8342 Rs./MJ, respectively. Diesel fuel contributed highest share of input energy for paddy cultivation. Seed (52 %) contributed highest share of output energy, it immediately followed by straw (48 %).The contribution of indirect energy (53.64 %) was higher than that of the direct energy (46.16 %). In direct energy, the highest share of diesel fuel (82 %) as well as in indirect energy chemical fertilizers (49 %) contributed highest share. The share of non renewable energy (72.86 %) was found to be more than that of renewable energy (27.14 %).Water contributed highest share (46 %) to renewable energy and it immediately followed by human energy (30 %) stand on second position.Diesel fuel (52 %) contributed highest share to non renewable energy used and it followed by chemical fertilizers (30 %). The costs of different sources of input energy used in paddy cultivation were 19.995 Rs./MJ and that of output energy from paddy cultivation was 0.8342 Rs./MJ.Keywords
