Effect of in situ moisture conservation practices on environmental, energetics and economic comparisons on maize + blackgram cropping system in dryland ecosystem - Hisar, India : Agri-Bio-Publisher, 2016.
Peer review
A field study was conducted at Dryland Farming Research Station, Arjia Bhilwara (Rajasthan) during the kharif seasons to assess environmental, energetics and economic comparisons of in situ moisture conservation systems in maize based cropping system and their effect on crop productivity under dryland ecosystem. Among the different cropping systems, strip cropping of maize-blackgram (4:8) was found the most effective in improving environment, energetics and economics and increased maize equivalent yield by 98.4% over control [maize+blackgram intercropping (2:2)]. Ridging after first intercultural operation (RAFIO) reduced the runoff by 25 to 28% and 44 to 45% deep and shallow tillage, respectively. Deep tillage decreased the runoff by 52 and 51% in paired intercropping and strip cropping, respectively, over shallow tillage. RAFIO increased mean maize grain equivalent yield by 27 to 41% over deep tillage and by 36.02 to 47.59% over shallow tillage in strip cropping and paired intercropping, respectively. RAFIO increased mean net returns by 39 to 106% over deep tillage and by 67.8 to 156.5% over shallow tillage. Deep tillage increased the yield by 40.4 and 39.4% under strip cropping and intercropping system of maize. Fertilizer accounted for maximum share of energy input (43.02-76.69%) followed by tillage (4.15-32.60%) in different in situ moisture conservation practices under maize-blackgram cropping system. The deep tillage required 6.59 times higher energy input as compared to shallow tillage (281.4 MJ/ha). The energy input for ridging after first intercultural operation was higher (49.18%) in paired intercropping of maize + blackgram (90/30) as compared to strip cropping of maize-blackgram (4:8). This might be due to increased area for maize crop.
