THE EFFECT OF CHICKEN MANURE AND PLANT ORGANIC NUTRITION (N0T) LAU KAWAR ON THE GROWTH AND YIELD OF RED CHILI PLANTS (Capsicum annuum L.) BAJA F1 VARIETY

Abstract

Red chili is one of the vegetable commodities that is widely cultivated by farmers in Indonesia because it has a high selling price so it has good prospects for cultivation. The research objectives were: (1) to determine the effect of chicken manure and NOT Lau Kawar and their interaction on the growth of red chili plants, and (2) to obtain the correct dose of chicken manure and NOT Lau Kawar concentration on the growth and yield of red chili plants of the Baja F1 variety. The research was carried out from November 2021 to April 2022 on the grounds of the Samarinda Agricultural Development Vocational School, JL. Thoyyib Hadiwijaya, North Samarinda District, East Kalimantan, Indonesia. The research used a Completely Randomized Design (CRD) with 4x4 factorial analysis which was repeated 4 times. The first factor is the dose of chicken manure (A) consisting of 4 levels, namely: a0 = without giving chicken manure; a1 = 37 g polybag^-1; a2 = 52 g polybag^-1; and a3 = 75 g polybag^-1. The second factor is the concentration of NOT fertilizer (N) consisting of 4 levels, namely: n0 = without NOT fertilizer; n1 = 18 ml l^-1 water; n2 = 28 ml l^-1 water, and n3 = 38 ml l^-1 water. Research activities include (1) preparation of the research site; (2) preparation of planting media; (3) nursery; (4) giving chicken manure; (5) planting; (6) giving NOT Lau Kawar; (7) plant maintenance includes watering, replanting, weeding, installing stakes, pest control; (8) harvesting. The results of the research showed that: (1) chicken manure treatment was affected significantly to very significantly on the plant height at 10, 20, 30, and 40 days after planting, plant age at harvest, number of fruit per plant, and fruit weight per plant. but has no significant on the plant age at flowering; (2) NOT Lau Kawar treatment was affected significantly on the plant height at 10, 20, 30, and 40 days after planting, number of fruit per plant, and fruit weight per plant, but no significant on the plant age at flowering and age plants at harvest; (3) the interaction between chicken manure treatment and NOT Lau Kawar was affected very significantly on the plant height at 10, 20, 30 and 40 days after planting, and fruit weight per plant, but no significant on the plant age at flowering. age of plants at harvest and the number of fruits per plant; and (4) The highest fruit weight per plant was produced in a combination of 75 g polybag-1 chicken manure and 28 ml l^-1 NOT Lau Kawar (a3n2) water, namely 445.75 g plant^-1, while the lowest was produced in the treatment combination without chicken manure and NOT Lau Kawar (a0n0) namely 155.00 g plant^-1.
