Abstract

The community service took place for the Women Farming Group (WFG) of Banda Langik in the Sungai Bangek, Balai Gadang, Koto Tangah District, Padang City, from July to November 2022. It was held in demonstration plots (dump lots) of Liquid Organic fertilizers (LOF) with coconut coir, and banana stems as raw materials. These raw materials were straightforward to find in this area. Plots were made of 2 beds, and each was planted with pull-out Kale from seeds. Each bed was divided into two parts: without LOF and given LOF. It helped the WFG members differentiate the growth and yield pull-out Kale between being given LOF and without LOF. LOF was made by fermenting coconut coir separately and banana stems in a closed bucket for two weeks. The fermented products were sprinkled on the plants every week, starting at the age of two weeks after planting until they were close to harvest. The results showed that the plants given LOF were higher than those without LOF. The plant has given LOF more leaves. Their length and width of leaves were more significant than those without LOF. LOF is very useful given to vegetable plants, especially pull-out Kale.

Abstract

Salibu is a rice plant that grows after the stems left over from the harvest have been pruned. Salibu cultivation has many advantages, including being able to increase land productivity through increasing the harvest index, and reducing production costs. There are many factors that effect growth in rice cultivation, including the height of cutting stems from harvest residues and weeds. Research was conducted from July to December 2020 at Pasar Ambacang, Kuranji District, Padang City with an altitude of 250 m above sea level. The experimental  units were laid out according to a Randomized Block Design (RCBD) with two factors and four replications. The first factor is the frequency of weeding which consists of 3 levels (weeding 1, 2 and 3 times) and the second factor is the cutting height which consists of 3 levels (3-7 cm, 12-16 cm and 21-25 cm). The results showed that there is no interaction between weeding frequency and stubble length on the growth of salibu rice plants. The stump length affects the height of the plant where the stump length of the 21-25 cm has higher plants than the others. Keywords : Weed, rice, growth  INTISARIPadi salibu merupakan tanaman padi yang tumbuh setelah batang sisa panen dipangkas.

Abstract

One of the efforts that can be done is to increase the national corn productivity by developing prolific composite corn varieties. This is done because prolific corn is a type of corn with a tendency to produce two or more cobs, so that it can increase the value of corn production. The purpose of this study was to obtain prolific corn candidates (two cobs) with high yield and uniformity. This research was conducted using the mass selection method. Mass selection is done by selecting plants that have the desired character, namely prolific corn (cob two). The observed variables were the diversity in the F4 population, the percentage of prolific maize, and the comparison of the yield components of prolific maize with non-prolific maize. This study succeeded in obtaining 50% prolific corn on the cob and has wide diversity criteria. Of the 561 prolific corn plants, there are 91 corn plants that are classified as productive prolific. Prolific maize has a higher yield component than non-Prolific maize. Seed weight with cobs on productive prolific corn reached 318 g and seed weight reached 268 g.

Abstract

Weeds are plants whose presence is unwanted by humans because of competition with cultivated plants for nutrients, sunlight, and growing space, producing allelochemicals that interfere with plant growth, reduce production and product quality, and increase farming costs. The continuous use of synthetic herbicides has adverse effects on the environment and health, so it is necessary to seek a weed control mechanism that is more efficient and environmentally friendly. One is utilizing secondary metabolites, namely sunflower plant allelochemicals, that can control weeds. This study aims to determine the response of weeds to the application of extracts of sunflower plant parts as bioherbicides. This research was conducted in three stages: raw material preparation, extraction, and application. The results obtained 17 weed species in the experimental field of Nagari Selayo Tanang Bukit Sileh from 7 families (Asteraceae, Poaceae, Lythraceae, Polygonaceae, Brassicaceae, Caryophyllaceae, and Mazaceae) and two weed classes (broadleaf weeds and grasses). The bioherbicide efficacy of sunflower extract (Helianthus annus L.) has not caused symptoms of toxicity in weeds.

Abstract

Success in cultivating potatoes is the use of good quality potato seeds. Good quality potato seeds are produced through several stages starting from in vitro culture to extension seed production. One of the important stages in potato seed production is the production of first generation (G1) potato seeds. Efforts to increase the yield of G1 tubers can be made through modifying the planting media and applying growth regulators. This research aims to produce G1 potato tubers by adjusting the composition of the planting media (cocopeat, cocofiber, charcoal husk) and applying a growth inhibitor (Daminozide). The research consisted of four series of experiments. Each experiment was carried out using a Completely Randomized Design (CRD) with six treatments, each repeated four times. Experiment 1 (a. Cocopeat 100% + 0% husk charcoal; b. Cocopeat 20% + 80% husk charcoal; c. Cocopeat 40% + 60% husk charcoal; d. Cocopeat 60% + 40% husk charcoal; e. Cocopeat 80% + Charcoal Husk 20%; f. Cocopeat 0% + Charcoal Husk 100%. Experiment 2 (a. Cocofiber 100%; b. Cocopeat 100%; c. Cocopeat 20% + Cocofiber 80%; d. Cocopeat 40% + Cocofiber 60%; e. Cocopeat 60% + Cocofiber 40%; f. Cocopeat 80% + Cocofiber 20%. Experiment 3 (a. Cocopeat + Cocofiber + husk charcoal (1 : 1 : 1); b. Cocopeat + Cocofiber + charcoal husk (1 : 1 : 2); c. Cocopeat + Cocofiber + husk charcoal (1 : 2 : 1); d. Cocopeat + Cocofiber + husk charcoal (2 : 1 : 1). Experiment 4 (a. Daminozide 0 ppm; b. Daminozide 500 ppm; c. Daminozide 1000 ppm; d. Daminozide 1500 ppm). From the research results it can be concluded: 1) The combination treatment of 80% cocopeat + 20% cocofiber is the best treatment combination in the vegetative growth phase; 2) Composition treatment 60% cocopeat + 40% husk charcoal is the best treatment for the growth and number of G1 potato tubers; 3) Treatment of the composition of the planting media with cocopeat, cocofiber, and husk charcoal with a composition of 1:1:1 produces the highest number of tubers; 4) The best concentration of daminozide for the growth and production of G1 potato seed tubers is 3500 ppm.

Abstract

Utilization of marginal land, such as peatlands, to increase national rice production needs to be done. This is because the need for rice consumption increases yearly, while many productive lands have been converted for settlements. The provision of amelioran dolomite lime on peatlands before cultivating rice plants can be done to overcome problems on peatlands. This study aims to see how the growth and yield responses of the Caredek variety of rice on peatlands are due to the administration of several doses of dolomite lime. The study used a Randomized Block Design consisting of 4 dolomite lime dose treatments, including 0 tons/ha, 5 tons/ha, 10 tons/ha, and 15 tons/ha. Each treatment was repeated 3 times. Data were analyzed using the F test at a 5% level, and the DNMRT test was continued at a 5% level if it showed a significantly different effect. The results showed that the administration of dolomite lime affected growth (plant height and leaf area index) but did not affect the yield of the Caredek variety of rice on peatlands. A dose of dolomite lime of 5 – 15 tons/ha is generally effective in increasing the growth and yield of Caredek variety rice plants on peatlands compared to not applying dolomite lime.
