Abstract

Due to declining soil fertility as a consequence of continued land usage, the production of red curly chilies has decreased. Fertilization, both biological and inorganic, is one strategy that may be used. The goal of this research was to ascertain the effect of a fertilizer mixture on the growth and production of red curly chili. Land preparation, planting, application of biological and inorganic fertilizers, and observation of growth and production were all included in the study phases. The study was done in a factorial experiment with three replications, with factor 1 being biological fertilizer and factor 2 being the kind of micro fertilizer. At 0, 30, 60, and 90 days after planting, bio-fertilizers, NPK, and micro-fertilizers were applied four times. The height of the plant, the diameter of the crown, the number of chilies, the length of the fruit, the weight of the chilies, and the diameter of the chilies were all recorded. The collected data were examined statistically using Analysis of Variance (ANOVA) and the Duncan Multiple Range Test (DMRT) at the 5% and 10% levels. The findings indicated that micronutrient brand B treatment had an effect on plant growth. Plant production is affected by the use of biological fertilizers.

Abstract

The basic concept of organic farming prevents synthetic chemical compounds from using fertilizers, pesticides, and growth regulators. Natural insecticides are alternative pesticides in pest control on plants because they are available around us and have a good impact on the sustainability of the agricultural environment. This study aims to examine the level of toxicity of several alternative insecticides in controlling the walang sangit  (Leptocorixa acuta). The research in the laboratory and greenhouse of Instiper Yogyakarta uses 3 natural ingredients, namely neem leaves, tobacco leaves, and C. Odorata weed leaves at 2 stages of L. acuta on instra 3-4 and adults. Observations were made by looking at pest mortality, attack rate, and yield and analyzed using SPSS 16 software. The results showed that tobacco leaf extract was the most effective source of insecticide, with a mortality rate of up to 90% and damage rates below 9%.
