Evaluation of fodder cropping sequences under Tarai region of Uttarakhand

Abstract

Field experiments were carried out to record the performance of twelve cropping sequences in randomizedcomplete block design with three replications during 2015-16 and 2016-17 at Pantnagar. Different croppingsequences were assessed for fodder and nutrient yields, production and land use efficiency, profitability and soilorganic carbon sequestration. Study revealed that hybrid apier + berseem cropping sequence N (CS ) had higher 12green fodder (185.8%) and dry fodder (306.7%) yields than commonly practiced single cut sorghum + cowpea-oat+ berseem-single cut sorghum + cowpea cropping sequence (CS ). This also had significantly higher digestible 1dry matter (77.3 t ha ), crude protein (11.4 t ha ) and mineral (10.0 t ha ) yields than CS . Production efficiency with -1 -1 -11 this treatment was 1.33 and 0.40 t ha day in terms of green and dry fodder yields, respectively against 0.53 and -1 -10.11 t ha day , which was observed in CS . CS was the most profitable cropping sequence showing 285.6, 235.1 -1 -11 12 and 222.2% higher net return, B:C ratio and economic efficiency, respectively than commonly followed croppingsequence (CS ). However, CS and CS were at par with respect to soil organic carbon sequestration. So hybrid 1 12 1Napier + berseem cropping sequence (CS ) could be recommended for Tarai region.
