Abstract
The reduction in agricultural land due to land conversion and climate change has encouraged several technological innovations in cultivation systems, including intercropping planting patterns in dryland. Dryland is a potential future as productive agricultural land and to improve the efficiency of land use and the intercropping system is an option in agricultural cultivation. The objective of this research was to determine the nutrient concentration of nitrogen and phosphorus on intercropping several varieties of maize and soybean in dryland. The method used in this study was 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 treatment was repeated three times to obtain 15 experimental plots. Parameters that were observed in this study, namely, the concentration of N, P, organic C content and pH of the soil at 40 das (day after seedling) and 92 das, uptake of N and P per plant at 40 das. Data were analyzed using analysis of variance at 5% significance level and if the treatment was significantly different then further tested using LSD at 5% significance level. The impact of climate change is the occurrence of a shift in the nutrient concentration of N, P, C-organic content, and pH in the soil at 40 or 92 das and the uptake of N and P nutrients in the plants at 40 das on intercropping maize varieties Bisi 18 and soybean varieties Biosoy II obtain the highest value. This study recommends that the improvement of nitrogen and phosphorus status in climate change can be achieved by intercropping Bisi 18 corn and Biosoy II soybeans in the dryland of North Lombok
