Intercropping tapioca (Manihot esculenta Crantz.) with pulses and groundnut

Abstract

An experiment was conducted in the College of Agriculture, Vellayani during the year 1977-1978 to study the performance of tapioca intercropped with different legumes (Blackgram, cowpea, greengram and groundnut) applied with different fertilizer, half the recommended dose and full recommeded dose). The experiment was laid out in a randomised block design with three replications. The experiment was conducted under rainfed conditions. The results revealed that the growth as measured from height and number of leaves and yield of tapioca as adjudged by the various yield attributes was not depressed by growing the four legumes at the three levels of fertilizers. On the other hand the quality and size of tapioca tubers were improved due to legume intercropping. The dry matter content, starch content and the HCN content of tapioca tubers were increased significantly due to growing of legumes in association with tapioca.
