Description
Summary:Intercropping with peanuts was reported to increase yield of cereal crops. The objective of this study was to examine the effect of peanut-intercropping and organic waste application on some soil chemical characteristics and red-rice yield under aerobic irrigation systems. The experiment was conducted from May to August 2020 in West Lombok (Indonesia), under Split Plot design, testing two factors, namely intercropping (T1=monocropped rice; T2=rice+peanut intercropping) in the main plots, and organic waste application (L0=without organic waste, L1=application of rice husk, L2=rice husk ash, L3=rice husk ash and cattle manure) in the subplots. Results showed that intercropping did not affect soil chemical properties but it significantly increased number of panicles and filled-grains, 100 grain weight, and grain yield of red rice per clump (31.27 g/clump under monocrop and 41.50 g/clump under intercropping with peanut). In contrast, organic waste application significantly influenced soil chemical characteristics and red-rice yield (the highest yield of 43.52 g/clump under L3). The significant interaction between factors on 100 grain weight indicated that the highest weight (2.89 g) was on intercropped red-rice under L3 treatment and the lowest one (2.18 g) was on monocropped red-rice under L2 treatment.
