摘要
In semi-arid regions, production of good quality fodder is a challenge; cereal-legume intercropping can be a better alternative in improving forage yield and quality. The present study was conducted to assess the performance of feather Pennisetum (FP) in groundnut (GN) intercropping and for determining a sustainable forage cropping system. Therefore, an experiment was conducted with groundnut and feather Pennisetum as a monocrop and intercrop (2GN:1FP and 3GN:1FP), where FP was harvested at 60, 75, 90, and 120 days after sowing. The land equivalent ratio of intercropping was 15-29% higher indicating yield advantages and economic benefits over sole stands. Crude protein and fiber content was increased by 10 and 8% in intercropping, lignin content was reduced by 15% and neutral detergent fiber by 5% indicating the better quality of FP due to intercropping with GN. Intercropping of GN and FP increased the content of non-fibrous carbohydrate (13%), gas production (6.5%) and volatile fatty acids (6%) indicating better fodder digestibility. Furthermore, intercropping of GN and FP also increased the mineral content by 8-20% than sole stands. Apart from productivity, intercropping of FP and GN, improved water use efficiency over sole stand of both component crops. Considering, forage yield, quality and profitability, 3GN:1FP intercropping was superior and can be recommended as an alternative to monoculture. Our study concluded that in semi-arid regions double dual cropping of food and fodder can be achieved by intercropping which can provide opportunities to produce food and fodder simultaneously for livelihood, animal rearing and long-term sustainability.
