Description |
An experiment was conducted during 2003–05 to assess the production potential, biological and economic feasibility of intercropping maize with blackgram in different row proportions under rainfed conditions. Intercropping blackgram with maize, irrespective of row arrangements was found to be beneficial in increasing the system’s total productivity and yield advantage to the tune of 9.3–48.0% under different intercropping systems compared to monocultures of both maize and blackgram. Among the intercropping systems, maize (50 cm) with blackgram in 1 : 1 row proportion was proved to be the most efficient, productive and remunerative as it gave the highest mean maize equivalent yield (3 430 kg/ha) and also accounted for highest values for land equivalent ratio (1.34), relative crowding co-efficient (4.49), area-time equivalent ratio (1.23), income equivalent ratio (1.52), sustainability yield index (0.90), production efficiency (36.9 kg/ha/day), net returns (8.54×103 Rs/ha) and B: C ratio (1.78) compared to other intercropping systems, thus, can be suggested as a biological and economically sustainable intercropping system for higher productivity and profitability under rainfed conditions. Magnitude of reduction in yield of the base crop due to intercropping of blackgram was the highest (41.8– 46.2%) when maize was widely planted either at 75 or 90 cm in 1: 2 row ratios as against the 21.8–27.1% for maize planted at 50/60 cm in 1: 1 row proportion. Paired row planting showed yield reduction to the extent of 29.0–29.8%. PAU Ludhiana |
