在雨养条件下，研究了20年生青冈(Prosopis Cineraria)对农作物粮食和饲料产量的影响。树木影响相关作物的饲料产量(青草和干草)。与单一种植饲料作物相比，雨季(哈里夫-7月-9月)和冬季(拉比-10月-1月)的饲料产量与khejri树的关系更大。对该系统的经济分析表明，任何一种连续种植的饲料作物与khejri联合种植都比单作获得更高的回报。最大净收益(Rs.15,197/ha)，效益成本比为3.73。哈里夫和拉比的粮食作物在与khejri一起种植时也比单独种植获得了更多的利润。(C)2003爱思唯尔科学有限公司。保留所有权利。
Effect of 20-year old khejri (Prosopis cineraria) trees on the grain and fodder yield of arable crops under rain-fed conditions was investigated. The trees influenced the fodder (green and dry) yield of associated crops. Fodder yield during both rainy (kharif-July-September) and winter (rabi-October-January) seasons was more in association with khejri trees as compared to sole cropping of fodder crops. The economic analysis of the system showed that higher returns were obtained when any of the fodder crops in sequence was grown in association with khejri than in monocropping. Maximum net returns (Rs. 15,197/ha) and benefit-cost ratio (3.73) was obtained when pearlmillet in kharif followed todia (Brassica tournefortii) in rabi under khejri trees. Grain crops, both in kharif and rabi also earned more profit when grown with khejri than alone. (C) 2003 Elsevier Science Ltd. All rights reserved.
