RECKONING THE IMPLEMENTATION OF PADDLE OPERATEDSINGLE ROLL FARM YARD MANURE APPLICATOR UNDERPROTECTED CULTIVATIONGargi Shekhar, Ramesh Pal, Happy Narang, Virendra Singh, Sachin Chaudhary,Satybhan Singh and T.P. SinghAbstract In Uttarakhand, due to adverse climatic condition, protected cultivation is a very extensively used methodfor cultivation of horticultural crops viz. tomato, capsicum, strawberry etc. The present study was carriedout in the crop research farm of Maya Group of Colleges, Dehradun in which a single roll farmyard manureapplicator was designed and developed and its performance evaluation was done on two plots, one plotwas an open field of size 2.5 *1.2 m2 and other was under protected cultivation was 200 m2 at different FYMdelivery rates and application rates. The mean draft requisite of single roll paddle operated farmyardmanure applicator at no load condition under open field and polyhouse was found to be65N and 68 with apower requirement of 24.7 KW and 25.84 KW at forward speed of 0.38 m/s respectively. In case of full loadcondition under open field and polyhouse was found to be134 N and 144 N with a power requirement of178.22 KW and 191.52 KW at forward speed of 1.33 m/s respectively. The efficiency of machine was foundto be highest at the speed of 4.48 km/h but leftover residue was found lowest at aperture opening of 8mm.Therefore, developed single roll paddle operated farmyard manure applicator was found workingsatisfactorily with prominent draftabilty of operator at different forward speed. |
