Influence on Intercropped Cajanus Cajan Caused By Land Configuration, Post-Monsoon Irrigation, and P Fertilization

Abstract

An on-field examination was performed at the Experimental Farm of Annamalai University during the rainy season of 2016. The main aim of the study was to assess the impact of the various factors on performance of pigeon-pea yield. In this experiment, the Cajanus cajan (L.) Millsp. [pigeon-pea] is the sole grown variety and intercropped with urdbean [Vigna mungo (L.) Hepper]. The two methods of planting are the broad-bed and furrow planting. At an irrigation of 0.4 IW: CPE ratio during post-monsoon period showed improved yield in case of pigeon pea. However, taking into consideration the flat bed planting with no irrigation, also showed similar increase in yield by 10%. The intercropping technique used for pigeon-pea with urdbean had no impact on the yield of pigeon-pea; however the yield increased in case of the additional urdbean, which eventually increased the total production rate of the pigeon-pea yield. The pigeon-pea yield increased up to 40 kg P2O5/ha, whereas the total productivity of pigeon-pea increased with the increased rates of Phosphorus up to 80 kg P2O5/ha.
