Efektivitas Rotasi Tanaman Terhadap Produksi Jagung Dilahan Kering

Abstract

Crop rotation is one of the cultivation strategies that can improve agricultural productivity, especially in dryland areas characterized by limited water and nutrient availability. This study aims to analyze the effectiveness of various crop rotation types on maize (Zea mays L.) production in dryland conditions. The research was conducted using a field experiment with a randomized block design (RBD) consisting of four treatments: maize after soybean, peanut, sweet potato, and continuous maize cropping (monoculture) as a control. The results showed that rotation with leguminous crops, particularly soybean, significantly increased maize yield compared to monoculture. In addition, crop rotation improved agronomic parameters such as plant height, number of leaves, and leaf greenness index. Soil conditions also improved, as indicated by looser soil texture and higher organic matter content. Thus, crop rotation is proven to be an effective and sustainable approach to increasing maize productivity in dryland farming systems.
