Technology package of land preparation with solarization and biofertilizer on chili

Abstract

Intensive land use without regard to soil fertility and health can reduce crop productivity. The purpose of this research was to compare yields of various packages of land preparation technology that can support soil fertility and health. The study was conducted in Cianjur Regency, West Java, Indonesia from June until November 2019. The study used a randomized block design with four treatments and six replications. The technology packages tested were the solarization of mulch installation, the use of biofertilizers, and chemical fumigation. Data were analysed by analysis of variance and followed by Duncan's test at the 95% confidence level. The results showed that there was no difference in fruit weight and number of fruits per plant, as well as weight per fruit in all treatments. However, the treatment of delaying planting for two weeks after mulch installation and the use of biofertilizer has the potential to be studied further because they were significant at several harvests. The weight per plant was 30.34-46.67 g higher than other treatments at the 4th harvest, the number of fruits was 3.2-11.67 higher at the 3-4th harvest, and the weight per fruit was 0.31-0.65 higher in the 2nd-5th harvest.
