Abstract

A study was conducted in Ihigetegera Village, Sikka Regency. The purpose of this study was to determine the effect of Green Tonic liquid fertilizer dosage on the growth and production of Karina tomatoes, and to determine the optimal dosage of Green Tonic liquid fertilizer that can achieve optimal production for Karina tomatoes. The treatments in this study included no fertilizer (control), 1 cc-1 fertilizer dosage, 3 cc-1 fertilizer dosage, 5 cc-1 fertilizer dosage, and 7 cc-1 fertilizer dosage. The results showed that Green Tonic fertilizer treatment significantly affected the number of leaves at 8 and 10 weeks after planting. It significantly affected plant height at 8 weeks after planting but had no significant effect at 10 weeks after planting. It significantly affected the number of fruits at 10 weeks after planting and significantly affected the fresh weight of fruits at 11 weeks after planting. The 3 cc-1 Green Tonic fertilizer dosage in this study was the best treatment for achieving the highest production of Karina tomatoes.

Abstract

MOL can be used directly as a liquid fertilizer because it contains complete nutrients (macro and micro) for plant growth and production, although the nutrient content is relatively low. To determine the nutrient content of MOL, an analysis was conducted at the Soil Chemistry Laboratory, Faculty of Agriculture, Nusa Cendana University, Kupang. The purpose of this study was to determine the macronutrient content (N, P, K, and organic carbon), and the micronutrient content (Mn, Fe, Cu, Zn), as well as the pH and C/N ratio of the resulting local microorganisms. The study was conducted at the Nusa Cendana University experimental garden for approximately four months, from February to July 2024. The macronutrient content of MOL was 16.95% organic carbon, 2.06% nitrogen, 0.29% phosphorus, and 1.85% potassium. 8.91% C-Organic, 2.79% N, 0.34% P, 1.32% K, based on gamal leaves; 0.23% C-Organic, 1.23% N, 0.18% P, 0.80% K, based on lamtoro; 3.44% C-Organic, 1.53% N, 0.20% P, 1.29% K, based on mustard green waste; 1.11% C-Organic, 2.78% N, 0.33% P, 1.17% K, based on cow rumen and the content of micro nutrients MOL research results are 4.01% Mn, 108.78ppm Fe, 0.03ppm Cu, 1.73ppm Zn, pH 4.07 and C/N Ratio 8.23 based on kerinyuh; 3.12% Mn, 100.91 ppm Fe, 0.03ppm Cu, 1.71ppm Zn, pH 4.89 and C/N Ratio 3.20 based on gamal leaves; 3.01% Mn, 101.11ppm Fe, 0.03ppm Cu, 1.70ppm Zn, pH 5.10 and C/N Ratio 0.18 based on lamtoro; 3.38% Mn, 104.5ppm Fe, 0.02ppm Cu, 1.65ppm Zn, pH 4.89 and C/N Ratio 2.25 made from mustard green waste. 3.70% Mn, 106.82ppm Fe, 0.03ppm Cu, 1.69ppm Zn, pH 4.98 and C/N Ratio 0.40 made from cow rumen.

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.

Abstract

The study entitled The Effect of Concentration and Soaking Duration of Neem Leaf Water Extract (Azadirachta indica) on Cocoa Pod-Sucking Bug Pests (Helopeltis spp.) was conducted at the Field Laboratory (LL) of the Department of Agriculture and Plantation of East Nusa Tenggara Province, located at RT 003, RW 009, Kota Uneng Village, Alok District, Sikka Regency, from April 2016 to June 2016. The objectives of this study were: (1) to examine the effect of the concentration of neem leaf water extract (Azadirachta indica) in controlling cocoa pod-sucking bugs (Helopeltis spp.); (2) to examine the effect of the soaking duration of neem leaf water extract (Azadirachta indica) in controlling cocoa pod-sucking bugs (Helopeltis spp.); and (3) to determine the combined effect of concentration and soaking duration of neem leaf water extract (Azadirachta indica) in controlling cocoa pod-sucking bugs (Helopeltis spp.). This study was a two-factor experiment, namely concentration and soaking duration, arranged using a Completely Randomized Design (CRD) with three replications, resulting in seventy-two (72) experimental units. Factor I: Concentration factor consisted of four (4) levels, namely: K0 = Control (without neem material/sterile water), K1 = Concentration of 1,000 ppm = 0.1%, K2 = Concentration of 2,500 ppm = 0.25%, and K3 = Concentration of 5,000 ppm = 0.5%. Factor II: Soaking duration factor consisted of six (6) levels, namely: L0 = Control (without neem material/sterile water), L1 = Soaking duration of 1 day, L2 = Soaking duration of 2 days, L3 = Soaking duration of 3 days, L4 = Soaking duration of 4 days, and L5 = Soaking duration of 5 days. The results showed that on the first day of observation, the lowest and highest average numbers of punctures were 62.25 and 104.25 punctures (control), 44.33 and 71.86 punctures (1,000 ppm treatment), 38.75 and 77.14 punctures (2,500 ppm treatment), and 32.14 and 65.17 punctures (5,000 ppm treatment), respectively. Based on these data, it was observed that there were differences in the number of Helopeltis punctures on cocoa pods due to the application of neem leaf pesticide on the first day. The application of neem leaf pesticide was able to reduce the number of Helopeltis punctures on cocoa pods. This effect continued until the 10th day of observation, where the average number of punctures decreased progressively (and even reached zero) as the concentration and soaking duration of neem leaves increased. By the 10th day, there were still 132 Helopeltis punctures on cocoa pods in the control treatment, while the number of punctures in the other treatments continued to decrease, with some treatments showing no punctures at all.
