In India, cotton is hand-picked by human labours, which is time consuming and tedious job. Keeping all these aspects in mind, a knapsack power driven cotton picker was developed with petrol engine of 0.9 kW, 5500 rpm. The other components were developed as per design requirements. The time requirement and cost of operation for knapsack cotton picker per hectare were worked out as 371 h and Rs. 11041/- respectively which showed 58.55 % saving in time and 21.25 % saving in cost over manual picking method. The higher value of energy was observed 2.61 times that of manual picking method. The...

Interspecific hybridization is useful to improve cultivated species by introgressing specific traits. The present investigation on interspecific hybrids of Luffa comprised of three genotypes of L. acutangula (ridge gourd); three genotypes of L. cylindrica (sponge gourd) and their six interspecific crosses. Analysis of variance revealed significant differences amongst families for all the traits except girth of ovary, vine length, internode length, fruit length and fruit yield. For most of the characters, significant average and better parent heterosis was observed. Amongst the various...
