Study on improvement of red chili pepper (Capsicum annuum L.) cultivation technology

Abstract

The excessive use of pesticides is a problem in vegetable production in Indonesia including in hot pepper chili cultivation. According to this condition, an experiment was conducted in Bocek village Karangploso district Malang Regency from May to November 2019. The study was arranged in a randomized block design with four treatments and five replications. The introduced treatment was the improvement of the integrated plant and resources management (IPRM) component technology i.e. seedling immunization with Amaranthus spinosus liquid extract as an inducer and the use of BaPf as a PGPR and biological control that compared to the farmer technology (existing). The result showed that the introduced technology treatment (seedling immunization + BaPf) gave a higher plant posture than the other treatments. The highest fresh fruit weight was obtained in this treatment. This treatment also produced the highest yield of about 0.81 kg plant⁻¹ or 21.48 tonnes ha⁻¹ or the highest 19,84 % than existing. The intensity of yellow virus and anthracnose diseases in the introduced treatment was lower than existing. Farming analyses showed that this treatment (B) resulted in a higher profit of about Rp 18,214,870/1000 m² with a 1,51 of B/C ratio.
