Abstract

Intermittent irrigation is one of the rice cultivation technologies developed in Indonesia and the world. This study aims to determine the interaction between superior rice varieties with a watering system and rhizobacteria population dynamics, root development, and rice yield. This research was conducted for four months. The study used experimental methods on land compiled with a Factorial 3x4 Strip-Plot experiment design with a Completely Randomized Block Design (RCBD). Factor I is a watering system consisting of 3 treatments i.e. conventional irrigation, intermittent irrigation ten days of dry 5-day watering, and intermittent irrigation seven days of dry 3-day watering. Factor II is rice varieties consisting of 4 i.e. Cempo Merah, Inpari 23, Sintanur, and Inpari 42. The results showed no interaction between the irrigation system and rice varieties to rhizobacteria populations, rooting, and rice yields. The 7-day drying watering system has a relatively larger population of Rhizobacteria in week 16 and increases the length of the roots than other watering treatments. Intermittent irrigation provides grain weight per clump, which is no different from conventional irrigation. Inpari 23 rice varieties have a population of Rhizobacteria week 16 more and weigh 1000 seeds higher than the varieties Inpari 42. The yield of superior rice varieties Inpari 23, Sintanur, and Inpari 42 is higher than Local Cempo Merah rice varieties. Inpari 23, Sintanur, and Inpari 42 varieties can be cultivated by intermittent irrigation.

Abstract

Banyuroto Village is located in a hilly area in Sawangan District, Magelang Regency so it is very suitable for cabbage horticulture farming. We conducted this study to analyze the factors affecting production in Banyuroto Village and the efficiency of using these factors. We conducted a census on three farmer groups in Kenayan and Grintingan hamlets, resulting in a total sample of 80 farmers. The method used is a quantitative approach using Cobb-Douglas type production function analysis. The analysis of cabbage farming showed that the variables of land area, seeds, manure, phonska fertilizer, HNO fertilizer, Calcium fertilizer, solid pesticides, liquid pesticides, and labor had a significant effect on cabbage production. Partially, seeds, phonska fertilizer, and labor production factors affect cabbage production. To analyze the efficiency of the use of production factors, labor production factors in its use is efficient.

Abstract

One agricultural product with significant economic worth is soybeans. In Indonesia, soybean production is still low, while demand is high. Soybean productivity on coastal sandland can be increased by increasing the effectiveness of fertilizer with the use of nano biochar-coated urea fertilizer. This investigation seeks to evaluate the efficacy of nano-biochar coatings applied to various forms of urea as a nitrogen slow-release mechanism to enhance the growth and yield of soybean crops in coastal sandy terrain. This empirical research was executed within the Agricultural Experiment Greenhouse at Muhammadiyah University of Yogyakarta from March to June 2022. The methodology employed was experimental research utilizing a single-factor design organized according to a Completely Randomized Design (CRD) comprising six treatments. Each treatment included six plant samples with three replications, specifically: Urea Prill, Nano Biochar Coated Urea Prill, Urea Granules, Nano Biochar Coated Urea Granules, Urea Tablet, and Nano Biochar Coated Urea Tablet. The findings indicated that applying nano-biochar derived from coconut shells to urea prill significantly promotes the growth and yield of soybeans within coastal sandy soil. In future agronomic applications, nano biochar-coated urea prill can enhance urea's efficacy and improve soybean yields.

Abstract

Intermittent irrigation in cultivating rice plants can reduce and save water needs. The study aims to identify NPK nutrient uptake in various kinds of irrigation to select the suitability of local rice varieties in several types of irrigation. The research was conducted in the Experimental Land, Soil, and Plant Nutrition Laboratory and Production Laboratory of the Faculty of Agriculture, University of Muhammadiyah Yogyakarta, for five months. The research method was conducted using a field experiment with a Randomized Complete Block Design (RCBD) of 3 repetitions and a 3 by 4 strip plot layout. Factor I, namely irrigation, includes conventional irrigation (A1), ten days of inundation and five days of drying (A2), and seven days of inundation and three days of drying (A3). Factor II is the rice varieties, including Rojolele Genjah (V1), Pandan Wangi (V2), Mentik Wangi (V3), and Ciherang (V4). The results showed no interaction between the irrigation type and the variety of the observed parameters. Irrigation does not affect the absorption of N, P, and K, but it affects the weight of rice clump grain. Variety influences the uptake of P and K in rice plants. The Pandan Wangi variety has a higher P absorption than other varieties. Rojolele varieties have higher K absorption than Pandan Wangi and Ciherang varieties. The grain weight per rice clump of the Pandan Wangi variety is heavier than that of other varieties. Grain weight per rice clump with 10-day intermittent irrigation: 5-day drying is heavier than conventional irrigation. It is necessary to develop rice cultivation of the Pandan Wangi variety with intermittent irrigation because it does not reduce the absorption of N, P, and K, and the grain per clump is heavier Contribution to Sustainable Development Goals (SDGs):SDG 2: Zero HungerSDG 6: Clean Water and SanitationSDG 12: Responsible Consumption and Production
