Abstract

This research program aims to determine the responsegiving organic fertilizer to the vegetative growth of robusta coffee plants (CoffeaCanephora). Using a 2 factorial Group Design (RAK), each treatment was given 3 replications. Factor 1 was liquid organic fertilizer for bamboo shoots (P0: control, P1: 200 ml + 1000 ml water, P2: 500 ml + 1000 ml water, and P3: 800 ml + 1000 ml water). Factor 2 is using vegetable compost (K0: control, K1: 10 grams/polybag, K2: 20 grams/polybag), K3: 30 grams/polybag). Parameters observed were plant height, number of leaves, stem diameter, and leaf width. Based on the data on the response variance of the application of liquid organic fertilizer (POC) for bamboo shoots, it was shown that there was no significant effect on the parameters of plant height, number of leaves, stem diameter, and leaf width at the ages of 2, 4, 6, 8, 10, 12 mst. The results of the response variance data for the application of vegetable compost showed no significant effect on the parameters of plant height, number of leaves, stem diameter, and leaf width at the ages of 2, 4, 6, 8, 10, 12 mst. And the results of the interaction of the two treatments showed no significant effect on the parameters of plant height, number of leaves, stem diameter, leaf width.

Abstract

The sustainability of cocoa production in Indonesia is faced with the problem of the cocoa pod borer (Theobroma cacao L.). In an effort to control the main pests on cocoa plants, various techniques can be used, namely control with the use of natural insecticides and control by technical culture in the form of pruning. Natural insecticide is an insecticide whose basic ingredients come from plants that are easilybiodegradablein nature, so they do not pollute the environment and are relatively safe for humans and livestock, because the residue is easily lost. Pruning is the act of removing part of the plant organs in the form of branches, twigs and leaves with the aim of obtaining good cocoa plant branches, regulating the distribution of production branches and leaves so that they are evenly distributed, removing unwanted plant parts, stimulating the plants to grow. form new organs, reduce the risk of pest and disease attacks, and increase the ability of plants to form fruit. The purpose of this study was to determine the response of the application of botanical insecticides and pruning to the control of the cocoa pod borer (Theobroma cacao L.). The experimental design used a non-factorial randomized block design consisting of 7 treatments. The treatment of vegetable insecticides consisted of 4 levels, namely I0 (Without insecticide = Control), I1 (vegetable insecticide made from srikaya seeds at a dose of 250 ml/liter of water), I2 (vegetable insecticide made from tuba root with a dose of 250 ml/liter water), I3 (vegetable insecticide made from tobacco leaves at a dose of 250 ml/liter of water). The pruning treatment consisted of 3 levels, namely I4 (Without Pruning (Control), I5 (Pruning Interval 7 days after the study) and I6 (Pruning Interval 14 days after the study). Observations consisted of attack intensity, level of damage caused by PBK attack, attack index and production Control of the cocoa pod borer by pruning and botanical insecticides on cocoa plants showed a significant effect on the parameters of attack intensity and level of damage at the age of 6 weeks, and the attack index at the age of 12 weeks. 2 msp, 4 msp, 8 msp, 10 msp, 12 msp, and the parameters of the level of damage at the age of 2 msp, 4 msp, 8 msp, 10 msp, 12 msp and the plant production parameters at the age of 12 msp showed no significant effect.

Abstract

This study aims to determine the effect of KNO3, H2SO4, and GA3 in breaking dormancy and germination of salak (Salacca zalacca) plants. In this study using a non-factorial randomized block design with one factor, namely P0 (control), P1 (KNO3 60%), P2 (KNO3 70%), P3 (KNO3 80%), P4 (H2SO4 60%), P5 (H2SO4 70%), P6 (H2SO4 80%), P7 (GA3 25 ppm), P8 (GA3 50 ppm), P9 (GA3 75 ppm), P10 (KNO3 60% and GA3 25 ppm), P11 (KNO3 70% and GA3 50 ppm), P12 (KNO3 80% and GA3 75 ppm), P13 (H2SO4 60% and GA3 25 ppm), P14 (H2SO4 70% and GA3 50 ppm), P15 (KNO3 60% and GA3 75). Parameters observed were germination, maximum growth potential, plant height, number of leaves, leaf length, and leaf width. Based on the results of the DMRT test at 5% level, it showed that each treatment had an effect on the chemical scarification treatment showing a significant effect on germination, maximum growth potential, plant height, number of leaves, leaf length, and leaf width. However, it did not have a significant effect on the number of leaves at 12 WAP, leaf width at 11 and 12 WAP. Keywords: Plant Height, Leaves, Leaf Width
