Abstract

This study aims to determine the effect of several types of color traps on the population of stink bugs in rice plantations (Oryza sativa L). This study was conducted from June to October 2023 in the rice fields of Bandar Tarutung Village, Angkola Sangkunur District, South Tapanuli Regency. This research method uses a non-factorial Randomized Block Design (RAK), with treatments consisting of 7 treatments and 3 replications, namely: W₀: Colorless trap, W₁: Yellow trap, W₂: Pink trap, W₃: White trap, W₄: Green trap, W₅: Blue trap, W₆: Red trap. The results showed that the largest population of stink bugs trapped was in treatment W1 (yellow trap), with a total of 31, therefore the best result among all treatments was W1 (yellow trap).

Abstract

This study aims to determine the effect of pruning on the growth and yield of cucumber variety Mercy. This research was organized using a Randomized Group Design (RAK) with treatments, namely: No pruning (P0), pruning shoots on the main stem (P1), pruning shoots of all lateral branches after the third internode (P2) and pruning 2 lateral branches that appear first after the 3rd internode (P3) with 5 replications. The variables observed in this study consisted of; plant length, number of leaves, total number of fruits, number of harvestable fruits, harvestable fruit length, harvestable fruit diameter, and harvestable fruit weight. Data were analyzed using the F test and if there were significant differences followed by the 5% BNT test. The results showed that the treatment without pruning (P0) was able to produce a better number of fruits than the pruning treatment, but the number of fruits produced was of poor quality. The best plant results were found in the shoot pruning treatment on the main stem (P1) because it was able to increase the number of leaves 24.19% compared to no pruning treatment (P0).
