Abstract

Efforts to increase domestic soybean production are still hampered by the use of low-yielding varieties and pest attacks caused by high temperatures that are relatively stable throughout the year. This research aims to obtain botanical pesticides and varieties that produce the lowest intensity of important pest attacks on soybean plants (Glycine max (L.) Merrill). The research method used was a factorial Randomized Block Design (RBD) which consisted of 9 treatments and was repeated 3 times. The first factor is Variety which consists of 3 levels, namely v1 (Anjasmoro), v2 (Grobogan), v3 (Nusa Sanggabuana).The second factor is Botanical Pesticides which consists of 3 levels, namely p0  (Control), p1 (Kenikir Leaves), p2 (Soursop Leaves). The results of the analysis of variance and DMRT test at 5% level showed that There was an interaction effect between the type of botanical pesticide and three soybean varieties on the intensity of important pest attacks at plant age of 9 WAP. The independent factors of the varieties showed significant differences in plant height at 14, 21, 28 and 35 DAP and number of pods.Meanwhile, the independent factor of applying kenikir leaf botanical pesticides showed the highest value for the number of pods and the lowest intensity of pest attacks at ages 3, 5 and 7 WAPbut was not significantly different from other treatments. Keywords: soybean varieties, botanical pesticides, pests

Abstract

The aplication of liquid organic fertilizer is carrid out in an effort to reduce the excessive use of inorganic fertilizers and increase the availability of soil nutriens so that plants can grow and produce optimal production. The purpose of this study was to determine the effect of dose banana peel liquid organic fertilizer (Musa paradisiaca) on the growth and yield of two lettuce varieties (Lactuca sativa L.) on each type of lettuce plants. This research was conducted at Baraya Garden Putra, Youngest Prince Street, Cisarua District, Sumedang Regency, West Java with an altitude of 538 meters below sea level in November 2021 – January 2022. The method used was experimental method with a factorial Randomize Block design (RBD) consisting of two factors with 8 treatments repeated 4 times. The first factor is banana peel liquid organic fertilizer wich consist of 4 levels, namely: P0 (0 ml/L), P1 (70 ml/L), P2 (90 ml/L), and P3 (110 ml/L). The second factor was lettuce varieties consisting of 2 varieties namely: V1 (new grand rapid) and V2 (red rapid). The results of the study showed that there was no interaction effect between the application of banana peel liquid organic fertilizer and the variety on all observation parameters except for the number of leaves aged 35 days after planting. No there was an independent significant effect on the type of variety treatment against all observation parameters except for the leaf area of the plantation. Red rapid variety (V2) gave the highest yield on the height parameter number of leaves, root length, fresh weight, root dry weight, and fresh root weight. Keywords: Banana Peel Liquid Organic Fertilizer, New Grand Rapid, Red Rapid

Abstract

Soybeans (Glycine max L. Merrill) are nicknamed Gold from the soil, which contributes to the provision of nutritious food. Soybeans are the most important staple food crop after rice and corn. The increase in national soybean demand is not matched by an increase in national soybean production. Domestic soybean production is only able to meet around 65.61% of domestic consumption. Efforts to increase soybean production through intensification and extensification of technical efficiency in soybean cultivation, namely organic fertilization. This study aims to obtain the best combination dose of goat manure, formula 100+ biofertilizer and formula 100+ liquid organic fertilizer for the growth and yield of soybean plants. The study was conducted in the village of Telukjambe Timur, Puseurjaya, Karawang Regency. The method used is an Experiment with a single factor Randomized Block Design with 6 treatments and 6 replications, consisting of: P1 (0.15 l/ha liquid organic manure), P2 (0.15 l/ha liquid organic manure + 5 tons/ha goat manure), P3 (0.15 l/ha liquid organic manure + 20 l/ha biological manure), P4 (0.15 l/ha liquid organic manure + 20 l/ha biological manure + 5 tons/ha goat manure), P5 (5 tons/ha goat manure), P6 (20 l/ha biological manure + 5 tons/ha goat manure). so that there are 24 experimental units. The data obtained were analyzed by the F test at a level of 5% with further testing by the Duncan Multiple Range Test (DMRT). The results showed that there was a significant effect of the combination of fertilizer types, namely goat manure + biological manure + liquid organic manure (POC), on the growth and yield of Grobogan variety soybean plants. For parameters such as plant height, number of leaves, root length, total number of pods, number of filled pods, dry weight of 100 seeds, number of seeds per plant, and seed weight per plant, the best treatment was obtained with a combination of Liquid Organic Mature (0.15 l/ha) and Biofertilizer (20 l/ha) (treatment P3). This treatment provided the best vegetative and generative growth results. Keywords: soybean, goat mature, liquid organic mature, biological mature
