Selective mechanization for enhancing productivity of rice cultivation.

An OFT was done in the Kharif of 2009 and Rabi of 2010. For this a 500m2 plot in a preselected village in Garhwa district of Jharkhand using mechanical transplanter. In Kharif 2009, significant grain yield (3.14t/ha) was obtained when transplanting was done with mechanical transplanter. All the yield parameters such as panicle number, panicle weight were highly significant in the treatment number 1. Similarly in Rabi, 2010, significant grain yield (3.26t/ha) was obtained when transplanting was done with mechanical transplanter. All the yield parameters such as panicle number, panicle weight were highly significant in the treatment number 1.The results indicated that mechanical transplanting reduced the human drudgery and labour inputs during both the seasons. Rice yields were enhanced by 4 .6 per cent during Kharif when compared with manual transplanting and 9.7 per cent higher yields in Rabi season.
