Abstract

Long beans are a food favored by Indonesian people because they have sufficient nutritional content for health. topping is a way to increase production. This study aims to determine the growth response and interaction of two varieties of Long Beans with different topping times. The research was conducted in Karawang Regency in July - August 2020. The method used was a randomized block design method with a split-plot design consisting of 2 factors. the first factor was the variety (v) with 2 levels, v1 (KP-1) and v2 (Katrina) with 4 replications. The second factor is the pruning time (p) with 3 levels, p0 (without trimming), p1 (pruning 20 days afterward), and p2 pruning 40 days afterward. If the treatment shows a significantly different effect, then proceed with the LSD 5% test. The results showed that the KP-1 variety with pruning treatment of 20 days after planting gave the highest yield with 348.20 grams per plant. Meanwhile, the highest yield of Katrina variety was in the treatment without pruning with a weight of 370.70 grams per plant.

Abstract

The brown planthopper is an important pest in rice cultivation which acts as a vector for viruses that cause grass stunt and hollow stunt disease which can cause rice plants to die or reduce production to the detriment of farmers. This study aimed to obtain a pest control technique capable of suppressing the population and intensity of brown planthopper attacks on rice plants. This study is an experimental study using single-factor Randomized Block Design (RBD) with 4 treatments and 6 replications: C (Control); CC (Combination Control); BC (Biointensive Control); SC (Synthetic Control). The analysis results obtained showed that the SC treatment gave the lowest attack intensity value of 0.00% - 28.67% with a total population of 0 - 89 individuals followed by CC (1.33% - 44.67%) with a total population of 2-114 individuals, BC (2.00%-46%) with a total population of 3 - 103 individuals, and C (2.00% -45.33%) with a total population of 3 - 102 individuals. Synthetic control can be recommended as an alternative pest control technique in reducing the intensity of brown planthopper attacks.
