Optimation of yield on peanut-sorghum intercropping in the dry land, North Lombok

Abstract

As a source of carbohydrates, sorghum can be used as an alternative for food diversification. To introduce more sorghum is by intercropping with peanuts without reducing the production of this main crop. This experiment aims to determine the pattern of plant arrangement and the best planting time in the peanut-sorghum intercropping system; indicated by the best growth and yield of peanut and sorghum plants. The experiment was conducted in Papak Village, Gangga, North Lombok by using a factorial randomized block design with 2 treatment factors, sowing time and plant arrangement. Sowing time of peanuts was carried out 14 days before, at the same time and 14 days after sorghum, while plant arrangement consisted of: intercropping of 1 row of sorghum on 1 row of peanuts, 2 rows of peanuts, 3 rows of peanuts, and 4 rows of peanuts; Overall, this experiment consisted of 12 treatment plots, replicated 3 times, so there were 36 experimental plots. The results show that sowing peanuts before sowing sorghum gave the highest yield of peanut and plant arrangement with 1 row of sorghum in every 4 rows of peanuts showing the best yield in this peanut-sorghum intercropping.
