Studies on Utilization of Organic Manures and Cropping System : I. Analysis of the farmyard manure production

Abstract

1. The amount of the manure production was influenced by that of the litter application. When applied 5 kg of litter a day, farmyard manure was produced 7.6 t per cow per year (20 kg per day). On the contrary, one cow produced only 4.0 t a year (11 kg per day) as applied 1 kg of litter. 2. The total labour requirement for the manure production and application to the field was 250 man-hours/year in the general system. But in the gulle system, only 14 man-hours was required i.e. about 5% of the general system.
