Effect of Intercropping on Mycorrhizal Populations, Growth, and Yield on Several Varieties of Maize (Zea mays L.) and Soybeans [Glycine max (L.) Merr.] in Dryland North Lombok, Indonesia

Abstract

Abstract Drylands plays an important role to increase agricultural production. In addition, it also contributes to land use efficiency. The intercropping system provides a solution to increase agriculture productivity in dryland. The objective of this research was to determine the mycorrhizal population, growth, and crop yield of several maize and soybean varieties grown in the field using an intercropping system. The methodology conducted in this study involved a randomized block design with 5 treatment intercropping varieties combination of maize and soybean, namely V1=NK212: Biosoy I, V2=Bima 20 URI: Dega I, V3=NASA 29: Detap, V4=Bisi 18: Biosoy II, V5=Srikandi Kuning: Anjasmoro. Each treatments were repeated three times to obtain 15 experimental plots. The results showed that the mycorrhizal population, growth, and yield of Bisi 18 maize intercropping and Biosoy II soybean varieties obtained the highest value. Mycorrhizal population, wet and dry biomass weight of root, shoots, yield, the highest was obtained in the intercropping of maize varieties Bisi 18/soybean variety Biosoy II. The highest yield was given by the intercropping of maize varieties Bisi 18 and soybean varieties Biosoy II with maize dry seed grain weight 7.4 tons/ha and a soybean dry seed grain weight of 0.94 tons/ha.
