Abstract

The objective of the study was to assess the application of crop cultivation technology and productivity of paddy rice in Dumoga District, Bolaang Mongondow Regency, North Sulawesi Province. The research was conducted from November to December 2022. The research was located in Dumoga District, Bolaang Mongondow Regency, North Sulawesi Province. This research was qualitative research by conducting surveys and interviews with 30 farmers in Dumoga Subdistrict using a prepared questionnaire, including the identity of farmers, farming conditions and cultivation techniques of paddy rice in Dumoga Subdistrict (North Mopugad Main Village, North Mopugad 1, North Mopugad, South Mopugad, South Mopugad 1, South Mopuya, and Amertabuana). The research location was determined by purposive sampling, namely Dumoga Sub-district, Bolaang Mongondow Regency, with the consideration that the area is the center of paddy rice production in North Sulawesi. The data analysis used was a qualitative descriptive analysis technique. The data obtained were then processed and tabulated in the form of tables and diagrams. The results showed that the application of paddy rice cultivation technology carried out by farmers in Dumoga District included the application of land preparation using a hand tractor, a single planting pattern, a direct seed planting system of direct seed planting (Tabela), the spacing used was 20×20 cm, fertilization using fertilizers (Urea, Phonska, TSP and SP36), water sources came from irrigation irrigation, pest control using pesticide active ingredients and harvesting already using harvesting machines, and paddy rice production in Dumoga District reached 4 tons of GKG, with a productivity of 1.6 tons/ha.

Abstract

This study aims to determinate the effect of the interaction between water hyacinth (Eichhornia crassipes) liquid organic fertilizer on mustard greens (Brassica juncea) fertilizer that affects the yield of mustard greens and determine the dose of inorganic fertilizer that affects crop yield mustard greens. This research was conducted in the village of Motoling, Kec. Motoling, south Minahasa Regency, North Sulawesi. The design of this study used a factorial randomized block design (RBD) with factor I, namely the dose of water hyacinth liquid organic fertilizer, and factor II, namely the dose of inorganic fertilizer. The variables observed were: plant height, number of leaves, leaf lenght, leaf width and wet weight. The results showed that the interaction between water hyacinth liquid organic fertilizer and inorganic fertilizers had an effect on the fresh weight of mustard green plants and had no effect on plant height, number of leaves, leaf length dan leaf width of mustard green plants.

Abstract

The purpose of the research was to study the effect of biourine on soybean plant growth, and to obtain the concentration of biourine that can increase soybean growth. To achieve the objectives, the research was designed using a completely randomized design. The treatments consisted of, A = No Biourine, B = 100 ml biourine/1 liter of water, C = 200 ml biourine/1 liter of water. Each treatment was repeated four times resulting in 12 experimental pots. The parameters observed were the number of leaves and the number of soybean branches. Data were analyzed using analysis of variance and 5% BNT test. The results showed that the application of biourine increased the growth of soybean plants as indicated by plant height and the number of leaves with three branches. The concentration of 100 ml biourine/1 liter of water increased the growth of soybean plants.
