Reckoning the implementation of paddle operated single roll farm yard manure applicator under protected cultivation

In Uttarakhand, due to adverse climatic condition, protected cultivation is a very extensively used method for cultivation of horticultural crops viz. tomato, capsicum, strawberry etc. The present study was carried out in the crop research farm of Maya Group of Colleges, Dehradun in which a single roll farmyard manure applicator was designed and developed and its performance evaluation was done on two plots, one plot was an open field of size 2.5 *1.2 m2 and other was under protected cultivation was 200 m2 at different FYM delivery rates and application rates. The mean draft requisite of single roll paddle operated farmyard manure applicator at no load condition under open field and polyhouse was found to be65N and 68 with a power requirement of 24.7 KW and 25.84 KW at forward speed of 0.38 m/s respectively. In case of full load condition under open field and polyhouse was found to be134 N and 144 N with a power requirement of 178.22 KW and 191.52 KW at forward speed of 1.33 m/s respectively. The efficiency of machine was found to 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 working satisfactorily with prominent draftabilty of operator at different forward speed.
