Abstract

This study aims to investigate the effect of goat manure fertilizer on the production of red spinach (Alternanthera amoena Voss) and soil organic carbon (C-organic) content in Brai Hamlet, Alok Timur District, Sikka Regency. The research was conducted from November to December 2022 using a randomized complete block design (RCBD) with five fertilizer dose treatments (control, 6 kg, 12 kg, 18 kg, and 24 kg per bed) and four replications. The results showed that the highest fertilizer dose (24 kg/bed) produced the highest yield of red spinach, reaching 3.88 kg per bed, while the control only produced 1.40 kg per bed. The application of goat manure fertilizer significantly affected plant growth and yield but did not show a significant effect on increasing soil C-organic content. Laboratory analysis indicated that the final soil C-organic content was classified as high to very high, but no significant changes were detected statistically. In conclusion, goat manure fertilizer effectively increases the yield of red spinach, but it has not yet significantly improved soil C-organic content within the research period.

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.
