Effect of Intercropping with Mungbean on Growth, Yield and Seed Protein Of White And Black Waxy Maise

Abstract

This study aims to determine the effect of intercropping on the growth, yield, and protein content of glutinous corn. This study used an experimental method with field trials in rainfed land in Rembitan village (Central Lombok) in December 2023-March 2024. The research design employed a Randomised Block Design (RBD) with two factors: White glutinous corn (J1) and purple glutinous corn (J2), with two treatments: without intercropping (T0) and with mung bean intercropping (T1). The researchers combined all factors to create four combinations, each replicated three times, resulting in a total of 12 experimental units. Observation variables include growth, yield and protein. Growth variables include plant height (TT) and the number of leaves (JD). Yield variables include the number of cob rows (JBT), the weight of 100 corn kernels per gram (BJ100/g), cob diameter (DT), weight of the cob without husk (BTTK), cob length (PT), and protein content (PrT).The results showed that the interaction of intercropping treatment with glutinous corn significantly affected the parameters of JD 42 and 56 hst, cob length, cob diameter, number of rows, weight of 100 grains, and cob weight. The most significant number of leaves was observed in the T1J1 treatment at 56 hst, with 14.55 strands. The longest cob size was observed in the intercropping treatment with white glutinous corn, measuring 18.20 cm, while the diameter of the purple corn cob was 47.90 cm. The researchers found that the T1J1 treatment produced the highest number of rows, 14.45, and a 100-grain weight of 23.04 g, followed by a cob weight of 140.19 g and seed protein content of 4.89%. Based on their results, they concluded that applying intercropping planting patterns can significantly enhance the growth, yield, and protein content of glutinous corn. Specifically, intercropping green beans with white glutinous corn resulted in the highest growth and yield, while intercropping with purple glutinous corn neither contributed to nor affected growth and yield.
