Abstract

Melon cultivation is usually cultivated in the highlands, but the development of melon cultivation in the lowlands has the potential to be developed. The problem is that ultisol with low fertility dominates the soil in the lowlands. Cultivating melons in polybags makes it possible to provide ideal nutrients for plant needs. The right frequency of fertilization can provide appropriate nutrients for each phase of plant growth. The study aimed to determine the best dose and frequency of potassium fertilizer application and the interaction between the two on the growth and yield of melon plants and the sweet taste of melons. The study used a randomized block design (RBD). Factor I: Potassium dose (D) 4 levels: control: 0 g per plant, D1: 30, D2: 40, D3: 50. The second factor is the frequency of application of Potassium (F) consisting of 3 levels, namely: F1: 4 times, F2: 6, and F3: 8. The results of the study showed that the frequency of application of potassium fertilizer had a significant effect on the flowering age of melon plants. A potassium fertilizer dose of 50 g per plant (D3) gave the best fruit weight and diameter and a higher sweetness than other treatments. Keywords: Lowland, Fertilization frequency, Polybag cultivation, Potassium dosage.

Abstract

The purpose of this study was to determine the distance and combination of fertilizers, and their interactions on the growth and yield of lowland rice. The design used is a split plot design. The main plot is the Planting Distance (J) which consists of 3 levels, namely: J1 : Conventional 20 x 20 cm, J2 : Jajar legowo 25 x 25 cm, J3 : Jajar legowo 30 x 30 cm. As a sub-plot is a combination of Petroganik (P ) fertilizer, Phonska, and urea which consists of 3 levels, namely, P1 : Combination of Petronic, Phonska and Urea fertilizers with a ratio of 3: 3: 2, P2 : Combination of Petronik, Phonska and Urea fertilizers with ratio 2 : 1 : 1, and P3 : Combination of Petronik, Phonska and Urea fertilizers with a ratio of 5 : 2 : 1. The results showed that plant spacing had no significant effect on plant height 30, 45, 60 and 75 DAP, the total number of tillers was 15 , 30, and 45 DAP, flowering age, harvest age, number of grain per panicle, production weight per plot and weight of 100 grains. Significant effect on the number of tillers aged 60 days, the number of tillers aged 75 days and clumped weight. The best spacing is 25 cm x 25 cm. The combination of fertilizers had a significant effect on the number of tillers aged 70 days, but had no significant effect on the other variables. The interaction of the combination of fertilizer and plant spacing gave a significant effect on the total number of tillers at 30 DAP, but had no significant effect on the other variables. The best results were obtained at a spacing of 25 cm x 25 cm with a combination of Petronik, Phonska and Urea fertilization with a ratio of 5: 2: 1

Abstract

This study aims to determine the effect of soil management system and dose of NPK fertilizer (15:15:15) on the growth and yield of tomato plants. The experiment used a Split Plot Design with 3 replications. As the main plot, there are types of tillage (P) consisting of 3 levels, namely: P1: No tillage; P2: Minimum Tillage; P3: Maximum Tillage. As a sub-plot, the dose of compound fertilizer NPK (15:15:15) consisted of 4 levels, namely: D0 : No fertilizer (control) equivalent to 0 kg/plot; D1: A dose of 125 kg/ha is equivalent to 37.375 g/plot; D2: The dose of 250 kg/ha is equivalent to 74.75 g/plot; D3: The dose of 375 kg/ha is equivalent to 112.125 g/plot. The results of this study showed that the type of tillage had no significant effect on plant height and number of fruit per plant, but had a very significant effect on fruit weight per plant and fruit weight per plot. Maximum tillage gave the highest fruit weight per plant and fruit weight per plot. The dose of fertilization with NPK compound fertilizer (15:15:15) had no significant effect on plant height, but significantly on the number of fruits per plant, fruit weight per plant and fruit weight per plot. The application of NPK fertilizer at 375 kg/ha gave the highest number of fruit per plant, fruit weight per plant and fruit weight per plot. The interaction between the types of tillage and the dose of NPK compound fertilizer had no significant effect on plant height, but significantly on the number of fruits per plant, fruit weight per plant and fruit weight per plot. If applying the system without tillage, it must be followed by fertilizing NPK fertilizer at 375 kg/ha, if applying a minimum tillage system it must be followed by NPK fertilization at a dose of 375 kg/ha, but if applying the maximum tillage, it is enough to fertilizing NPK fertilizer at a dose of 125 kg/ha to obtain optimal number of fruits and tomato fruit weight. The highest yield was obtained in the combination of maximum tillage treatment with a fertilizer dose of 375 kg NPK/ha.

Abstract

This study aims to determine what factors influence the production of lowland rice in Talang Kering Village, Air Napal District, North Bengkulu Regency. In this study, the samples taken were 27 respondents from a total of 80 populations. The data used are secondary data and primary data, the analysis used in this study is Cobb-Douglass and uses SPSS analysis. Cobb-Douglass is a function or equation that involves two or more dependent variables that are explained (Y), and the others are called independent variables that are explained (X). The results of the regression coefficients show that production is influenced by seed (0.50), land area (0.389), fertilizer (0.209), and use of pesticides (0.181) which greatly affect production while labor (-0.043) does not affect rice production.

Abstract

This research aims to obtain suitable alternative nutrients for vegetable cultivation using the Hydroponic Wick System so that the production costs of hydroponic cultivation can be cheaper and more affordable. The research was conducted in the Tebeng area, Ratu Agung Kodya Bengkulu, at an elevation of 50 meters above sea level. The research method used was a Randomized Block Design with a Factorial pattern (RAKF). The first factor had 3 levels of vegetable types: kailan (S1), caisim (S2), and pakcoy (S3). The second factor had 3 levels of nutrients: AB Mix 100% (N1), alternative 100% (N2), and ABMix 50% + alternative 50% (N3). Thus, there were 9 treatment combinations with 3 replications. The results of the research showed that the plant height, number of leaves, wet weight, and dry weight of plants using Alternative Nutrients for kailan, caisim, and pakcoy vegetables significantly influenced the use of AB Mix nutrients, Alternative Nutrients, and the mixture of both nutrients when grown using the Hydroponic Wick system. The best results were achieved using alternative nutrients. This was evident from the tallest plant height at harvest, which was 34.20 grams at 42 days after planting (HST), 16.62 leaves, 142.69 grams wet weight, and 7.60 grams dry weight. These results were significantly better compared to using other nutrients, offering a potential solution to the high costs of hydroponic cultivation due to the expensive price and limited availability of AB Mix nutrients, especially in the region.

Abstract

This research aimed to determine the effect of shoot cutting combined with spraying growth regulators on the growth and yield of soybeans. The experiment was arranged in a factorial randomized block design and was repeated three times. Shoot cutting treatments were performed 10, 20, and 30 days after planting. The growth regulators applied were Cytokinin, Auxin, and Gibberellin. The growth and yield of soybean plants were observed through plant height, number of branches, percentage of canopy coverage, leaf area, number of pods, weight of 100 seeds, and number of seeds per plot. The results showed that the interaction of the two treatments had no significant effect on soybean growth and yield. The Gibberellin treatment significantly affected plant height at 6 weeks after planting, number of branches at 4 weeks after planting, number of pods, and yield per plot.
