Abstract

The present study was carried out at Zonal Agricultural and Horticultural Research Station, Babbur Farm, Hiriyur, Chitradurga, Karnataka during rainy (kharif) season 2019, 2020, 2021 and 2022 to study the productivity and economics of maize (Zea mays L.) + field bean (Dolichos lablab L.) (4:2) intercropping system under different farming practices. The experiment was laid out in randomized complete block design (RCBD) with four farming practices as treatments, viz. T1, Natural farming (NF); T2, Organic farming (OF); T3, Recommended package of practices (RPP) and; T4, Farmer practices (FP) with five replications. Results revealed that the recommended package of practices (RPP) recorded a significantly higher maize grain yield (6045 kg/ha), seed yield of field bean (538 kg/ha), maize equivalent yield (9625 kg/ha). Cost of cultivation in different farming practices indicated the lowest labour cost incurred in organic farming (₹25405/ha) and material cost in natural farming (₹14576/ha) as compared to other farming practices. Among the farming practices, lowest cost of cultivation was observed under natural farming (₹45436/ha) as compared to other farming practices. The gross returns (₹166471/ha) and net returns (₹109428/ha) were again significantly higher in RPP over other farming practices.

玉米(Zea mays) +大田大豆(Dolichos lablab)间作系统在自然、有机和传统耕作方式下的生产性能

本研究于2019年、2020年、2021年和2022年雨季在卡纳塔克邦Chitradurga Hiriyur Babbur农场的区域农业和园艺研究站进行，研究不同耕作方式下玉米(Zea mays L.) +大田大豆(Dolichos lablab L.)(4:2)间作制度的生产力和经济性。试验采用随机完全区组设计(RCBD)， 4种耕作方式处理:T1，自然耕作(NF);T2、有机农业(OF);T3，推荐的一揽子实践(RPP)和;T4，农民实践(FP)，重复5次。结果表明，推荐操作包(RPP)可显著提高玉米籽粒产量(6045 kg/ha)、大田大豆种子产量(538 kg/ha)和玉米当量产量(9625 kg/ha)。不同耕作方式的种植成本表明，与其他耕作方式相比，有机耕作的劳动力成本最低(25405卢比/公顷)，自然耕作的材料成本最低(14576卢比/公顷)。在耕作方式中，与其他耕作方式相比，自然耕作方式的耕作成本最低(45436卢比/公顷)。总收益(166471卢比/公顷)和净收益(109428卢比/公顷)的RPP再次显著高于其他耕作方式。
