Further efforts were made to identify problems faced by farmers in the usage of each and every implement. Present study deals with the impact of farm mechanization on crop productivity in Vidarbha. Statistical tools and techniques employed as well as includes source of data, study area, selection of crops, period of study, analysis and interpretation of data. The study deals from the period of 2001 to 2015.Abstract The present study entitled “Impact of farm mechanization on crop productivity in Vidarbha” was undertaken to know the agricultural mechanization is the use and servicing of all types of agricultural tools, equipment and machines. Various types of agricultural operations performed on a farm seed bed preparation, cultivation, harvesting, transportation, silage cutting, feed grinding, threshing, winnowing and lifting of irrigation water etc. These operations are performed by different sources of power namely, human, animal, stationary engine, tractor, power tiller, electricity, solar and wind etc. Agricultural implements are devices attached to, pulled behind, pushed, or otherwise used with human, animal or mechanical power source to carry out an agricultural operation. Simple tabular analysis was used to study the status of farm implements and machineries at different points of times in different districts Vidarbha as compare to base year. Productivity of selected crops was worked out for the period 2000-01, 2005-06, 2010-11 and 2015-16 i.e. four-time stages based on study year. The compound growth rate is therefore estimated between two points of time i.e. the two agricultural censuses. Estimation composite index of agricultural mechanization was worked out on the basis selected indicator. (Prem Narian, 2007). Smaller value of Di indicates high level of development and higher value of Di indicate low level of development. Relationship between composite index of farm mechanization and productivity were studied using appropriate regression. The linear, quadratic, cubic, power and polynomial gave the best result. Hence, linear, quadratic, cubic, power and polynomial regression were taken into consideration. In Vidarbha, the availability of farm implements and machineries in 2005-06 over base period concluded that that lowest change was indicated 101.44 per cent in the number of ploughs while that highest 2429.60 per cent in the number of rotavators. Whereas during 2010-11 and 2015-16 ranges between 202.88 per cent to 4859.20 per cent and 398.32 per cent to 37954.78 per cent respectively the growth of rotavators was highest followed by tractors, harvesters puddlers and threshers. the productivity of cotton wheat and gram crops increased at 2010-11 over the base period and then decreased in 2015-16. during the study period. While the productivity of soybean crop decreased during 2005-06 and 2015-16 over the base period. Whereas productivity of rice crop increased during 2005-06 and 2015-16 over the base period. In Vidarbha, all selected indicators of farm mechanization the compound growth rate in 2005-06 ranges between 15.03 per cent to 90.81 per cent in 2005-06 over 2000-01. It indicates that highest growth rate of rotavators followed by tractors 84.34 per cent and harvesters 81.73 per cent and lowest growth observed ploughs in this period. In 2010-11 growth of farm mechanization was ranges between 8.33 per cent to 14.41 per cent. The comparison with 2005-06 has been lower growth rates were observed all indicators concluding that, farm mechanization indicators were reaching to stability on farm. Growth rate recorded in 2015-16 ranges between 7.50 per cent to 50.31 per cent. In this year shows that the highest growth rates in rotavators followed by tractors 43.72 per cent, electrical and diesel pumps 32.01 per cent and sprayers 22.68 per cent. It is revealed that during over study period i.e 2000-01, 2005-06, 2010-11 and 2015-16 Buldhana district secured first in mechanization. While that Gadchiroli, Bhandara and Gondiya districts retained its 11th, 10th and 9th position respectively during over study period. Amravati, Yavatmal, Nagpur and Akola districts are 2nd, 3rd, 4th and 5th position during 2010-11 while Amravati, Akola Yavatmal and Nagpur districts are 2nd, 3rd, 4th and 5th position in 2015-16. Agricultural mechanization and productivity of selected crops gave the highest R2 value in case of cotton crop i.e. 0.73 followed by gram 0.42. In wheat and rice the R2 value was same i.e. 0.37 whereas in soybean lowest R2 value was observed i.e. 0.31. It means the agricultural mechanization and productivity of selected crops explained the variation in productivity of cotton, soybean, rice, wheat and gram at the extent of 73 per cent, 31 per cent, 37 per cent, 37 per cent and 42 per cent respectively. It concludes that the year 2010-11 have highest and lowest significant effect of agricultural mechanization indicators on productivity. The availability of farm implements under the study have been over the period concluding that, the farmers are swinging over mechanization and that the significant change in farmers attitudes. The productivity of cotton wheat and gram crops increased at 2010-11 over the base period and then decreased in 2015-16. The overall scenario during the study period i.e. 2000-01 to 2015-16 concludes that, the growth performance on all twelve indicators of farm mechanization between first two points of time i.e. 2000-01 to 2005-06 was highest than the other two periods i.e. 2010-11 and 2015-16. It is revealed that during over study period i.e 2000-01, 2005-06, 2010-11 and 2015-16 Buldhana district secured first in mechanization indicate the change in development. While that Gadchiroli, Bhandara and Gondiya districts retained its 11th, 10th and 9th position respectively during over study period. agricultural mechanization and productivity of selected crops explained the variation in productivity of cotton, soybean, rice, wheat and gram at the extent of 73 per cent, 31 per cent, 37 per cent, 37 per cent and 42 per cent respectively. It concludes that the year 2010-11 have highest and lowest significant effect of agricultural mechanization indicators on productivity. Linear model was best fitted for relationship between rice productivity and farm mechanization in 2015-16 year was higher significant R2 effect of farm mechanization indicators on crop productivity. Linear model was best fitted for relationship between wheat productivity and farm mechanization in 2000-01 and 2010-11 year was higher significant R2 effect of farm mechanization indicators on crop productivity.EnglishThesis
