Quality, productivity and profitability of diversified fodder-based cropping systems for year-round fodder production in Indo-gangetic plains of India

Abstract

An experiment was conducted during two consecutive years of 2017-18 and 2018-19 at National Dairy Research Institute, Karnal under randomized complete block design (RCBD) with three replications. Thisstudy aimed to evaluate the performance of eight fodder-based cropping systems (CS) in Indo-gangetic plainregion (IGP) viz., sole napier bajra hybrid (CS ), sole guinea grass (CS ), napier bajra hybrid + cowpea (Kharif)/ 1 2berseem (Rabi) (CS ), guinea grass + cowpea (Kharif)/ oats (Rabi) (CS ), multicut sorghum-berseem (Rabi) 3 4(CS ), cowpea-maize-oats (CS ), baby corn-cowpea-chinese cabbage ( ) (CS ), summer moong–multicut 5 6 7 Rabisorghum–ryegrass (Rabi) (CS ). The results revealed that selection of the crops in different cropping systems 8significantly influenced green fodder yield and fodder quality. Among various fodder base cropping systems,NBH + cowpea/ berseem system was recorded with significantly higher green fodder (177 t/ha/year) and dryfodder (31.5 t/ha/year) yields and also fodder quality attributes. The highest crude protein yield (40.7q/ha/year) was also recorded in NBH + cowpea/ berseem intercropping system. In terms of economics, thehighest gross and net returns were obtained from baby corn-cowpea-chinese cabbage (Rs 3.15 and 2.40lakh/ha/year, respectively), closely followed by NBH + cowpea/ berseem (Rs 2.74 and 2.15 lakh/ha/year,respectively). To ensure the year-round availability of quality fodder for dairy-based farmers, cultivation of theNBH + cowpea/ berseem cropping system proved to be a viable option.
