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.

Abstract

This research aims to explore the optimization of land clearing techniques in supporting agricultural sustainability in Dahana Tabaloho Village, Gunungsitoli District, North Sumatra. This research involved students of the University of Nias Agrotechnology Study Program who applied land clearing techniques which included weed removal, soil loosening, drainage and bed making. The methods used in this study were direct observation, interviews, and measurement of soil parameters before and after the application of the techniques. The results showed that the combination of traditional and modern techniques in land management can improve tillage efficiency and environmental sustainability. The use of cultivators for soil loosening is proven to speed up the process, but still requires organic fertilizer to maintain the quality of the soil structure. Good drainage is effective in managing excess water and ensuring water availability during the dry season. In addition, making beds with proper direction supports optimal plant growth. The 15% increase in organic matter content and the stability of soil pH to remain neutral are indicators of the success of the applied techniques. Overall, this study provides evidence that proper land management can support sustainable agricultural productivity in the tropics.
