Abstract

Ende Sub-District, East Nusa Tenggara, has various topographies with an altitude of 0-1,100 m asl that can potentially grow Arabica coffee. Still, there is no information available regarding the suitability of the land. This study aims to evaluate the actual land suitability of Arabica coffee based on soil and environmental characteristics. The research method is descriptive explorative through a field survey approach supported by laboratory analysis. Determination of SMU (soil map unit) was carried out by purposive sampling through boring at 31 points, then classified based on soil type to obtain five pedons that represent SMU in Ende Sub-District. Soil sampling was carried out on each layer of each pedon. Data analysis used ANOVA and Pearson correlation tests to determine the determining factors that influence the land suitability class of Arabica coffee. The evaluation results showed that the actual land suitability for Arabica coffee was marginally suitable (S3) and unsuitable (N) classes, with limiting factors, i.e. average temperature, altitude, length of dry period, drainage, base saturation, available P, slope, and erosion hazard. The results of the ANOVA test showed that altitude significantly affected the land suitability class for Arabica coffee, with the best land suitability class at an altitude of 800-1,100 masl. Based on the correlation between land suitability class and land characteristic parameters, the determining factors for land suitability class include average temperature, humidity, drainage, texture, coarse material, total N, available K, erosion hazard, surface rocks, and rock outcrops. Land improvement recommendations are based on making an irrigation system, providing shade plants, N fertilization (urea fertilizer), K fertilization (KCl fertilizer), and terracing.

Abstract

Paddy fields with high agricultural activities greatly affect their quality. The purpose of this study was to determine the chemical properties and quality of paddy fields in Reroja Village. This study used an exploratory method. Soil samples were taken from paddy fields with three rice varieties, namely Inpari, Ciherang, and IR. The variables observed were soil pH, CEC, Organic C, Total N, Total P, Total K, and wet saturation. The criteria used in determining the location were paddy fields with an area of ??1 ha and cultivated rice varieties Ciherang, IR, and Inpari. The variables that had been analyzed were then determined for soil chemistry and soil quality criteria based on the Lowery scoring method. The results of the study showed that the pH of the rice field soil in Reroja Village was acidic with a pH value of 4.48 to 4.98, CEC was classified as high with a value range of 40.11 to 40.93, C-organic was classified as low with a value of 0.78 to 1.80, N-total was categorized as low with an inpari value of 0.08 to 0.15, P-available was categorized as medium and low with an inpari value of 30.10, 5.67 to 30.10, K-available was categorized as high with a value of 79.56 to 86.47, base saturation was categorized as high with a value of 87.90 to 88.11. The quality of the rice field soil in Reroja Village was said to be unhealthy, with a value of 1.7 to 2.0.

Abstract

Research was carried out to determine the effect of mycorrhizal doses and NPK fertilizer on the availability and uptake of NPK in corn plants. The research results showed that mycorrhizal inoculation and NPK fertilizer doses were able to increase the availability of soil NPK, plant tissue NPK, plant dry weight, and dry shelled seed weight. In the mycorrhizal and NPK inoculation treatment for all these variables, it showed an increase in all variables; however, mycorrhizal inoculation and NPK at a dose of 75% for each variable value decreased. The influence factors of mycorrhiza and NPK significantly increased these variables when compared to those without mycorrhiza and NPK fertilizer. The optimum dose of mycorrhizal inoculation fertilizer (m1, m2 and m3) and the dose of NPK fertilizer are each found at a fertilizer dose of 50.66% of the recommended NPK fertilizer (75.99 kg-1 ha urea, 25.33 kg ha-1 SP- 36 and KCl) or equivalent to 0.38 g/polybag urea and 0.31 g/polybag SP-36 and KCl), 45.11% of the recommended NPK fertilizer (67.66 kg ha-1 urea, 22.55 kg ha-1 SP-36 and KCl) or the equivalent of 0.34 g/polybag urea and 0.28 g/polybag SP- 36 and KCl, and 46.10% of the recommended NPK fertilizer (69.15 kg ha-1 urea and 23.05 SP-36 kg ha-1 and KCl) or equivalent to 0.34 g/polybag urea and 0.28 g/polybag SP-36 and KCl. The results of the optimum dose achieved in the combination treatment of mycorrhiza and NPK turned out to show the lowest optimum dose in the indigenous mycorrhiza treatment when compared to exogenous mycorrhiza. In the treatment without mycorrhiza (m0), there was a linear effect, namely, there was no optimum dose. Corn plants that are not given mycorrhiza require fertilizer at a dose exceeding 100% of the fertilizer dose given to reach the optimum dose.

Abstract

Research on the effect of urea fertilizer dosage on the growth response and production of Chinese cabbage plants in polybags, has been conducted in Nangameting Village, East Alok District, Sikka Regency from August to November 2024. The purpose of this study was to determine the effect of urea fertilizer on the growth and production of Chinese cabbage plants. The design used in the study was a Randomized Block Design (RAK) with five (5) treatments and four (4) replications so that twenty (20) experimental units were obtained, namely M0 (control), M1 (1 gr / polybag), M2 (3 gr / polybag), M3 (5 gr / polybag), and M4 (7 gr / polybag). The results showed that urea fertilizer administration had no effect on plant height and number of leaves in the first observation (14 hst), and in the second observation (28 hst) it had a significant effect on both variables. Meanwhile, for the production variable (wet weight of mustard greens) it showed that the urea fertilizer dosage treatment had a significant effect at the 1% and 5% unit BNT levels.
