Abstract

This research was carried out in the Dry Land of the Faculty of Agriculture, University of Nusa Cendana with the aim to investigate the effect of the application of cow manure and SP-36 fertilizer on the yield of bitter melon. This study was laid out in a randomized block design (RBD) with 6 doses of cow manure and SP-36 fertilizer applications, namely: K0 = without cow manure and SP-36 fertilizer (control), K1 = 10 tons/ha cow manure and SP- 36 fertilizer 50 kg/ha, K2 = 10 tons/ha cow manure and SP-36 fertilizer 100 kg/ha, K3 = 10 tons/ha cow manure and SP-36 fertilizer 150 kg/ha, K4 = 20 tons/ha cow manure and SP-36 fertilizer 50 kg/ha, K5 = 20 tons/ha cow manure and SP-36 fertilizer 100 kg/ha, K6 = 20 tons/ha cow manure and SP-36 fertilizer 150 kg/ha. Each treatment was repeated 3 times in block. The parameters observed were: flowering age, harvesting age, number of fruit/plant, fruit length, fruit weight/plant and fruit weight/plot. The results showed that the application of cow manure and SP-36 fertilizer had a significant effect on all parameters observed. The best treatment in increasing the yield of bitter melon plants was the application of cow manure with dose of 20 tons/ha and SP-36 fertilizer 150 kg/ha. At this treatment, plant had faster flowering and harvesting ages, namely 30 HST and 50 HST, and produced the highest number of fruit/plants (6.8), the longest fruit size (29.90 cm), the heaviest fruit/plant weight (1220.67 gram) and the heaviest fruit/plot weight (18.31 kg).

Abstract

This research was carried out at the Perum Kupang Warehouse, East Nusa Tenggara with aimed to determine the effectiveness of aluminum phosphide in controlling Rhyzoperta dominica in the Bulog Perum warehouse. This study was arranged in a completely randomized design (CRD) method with 5 treatment doses and each treatment was repeated five times. The variables observed were mortality symptoms of R. dominica, mortality of R. dominica treated with aluminum phosphide and rice loss. The results showed that the mortality of R. dominica treated with aluminum phosphide showed symptoms of body shrinkage as it gradually dried and became stiffer. Aluminum phosphide fumigant was toxic to R. dominica imago and each treatment had different level of toxicity. At doses of 8 g ton-1 and 18 g ton-1 of Aluminum phosphide fumigant, it could kill R. dominica imago ≥95%. The results of probit analysis showed that aluminum phosphide could kill 50% of the tested insects at a dose of 6.33 g ton-1 (LD50) and 18.37 g ton-1 (LD90) at one week after treatment (WAT), while at four WAT, at a dose of 1.28 g ton-1 (LD50) and 8 g ton-1 aluminum phosphide could kill 50% and 95% of insects tested, respectively. There was no rice shrinkage observed in each treatment, this is presumably because on the first day of weighing R. dominica imago had been exposed to phosphine gas and at one WAT the insects were removed from the sample sack and then transferred to a new container to observe weekly mortality.

Abstract

Dena-1 and Dega-1 are two soybean varieties that have been released as superior varieties, but have not been cultivated in the NTT Province. Therefore, this research aimed to evaluate the productivity of these two soybean varieties at various spacing planting in Kupang Regency. The experiment was a factorial trial laid out in a randomized block design (RBD). The first factor was soybean varieties (V), namely: Dena-1 (v1) and Dega-1 (v2) varieties. The second factor was the planting spacing (J) with five levels, namely: 40 cm x 10 cm (j1), 40 cm x 15 cm (j2), 40 cm x 20 cm (j3), 40 cm x 25 cm (j4) and 40 cm x 30 cm (j5). There were 10 combination treatments with three replications so there were 30 experimental units in total. Each experimental unit was laid in a plot of 2.0 m x 1.5 m. The data observed included: a) vegetative growth, b) generative growth, and c) supporting data. The data were analyzed using analysis of variance followed by DMRT at 5% significance level. The results showed that the interaction between treatments did not significantly affect all variables observed, however, the single factor of planting spacing and type of variety had a very significant effect on vegetative and generative growth. The 40 cm x 20 cm spacing planting gave higher seed weight per plot than the 40 cm x 25 cm and 40 cm x 30 cm spacing planting. The Dena-1 and Dega-1 varieties did not show any difference in seed weight per plot, but the weight of 100 seeds of the Dega-1 variety was greater than that of the Dena-1 variety.

Abstract

Dryland farming in Timor island is always constrained with the shortage of water supply, soil fertility as well as the availability of nutrients especially Phosphor (P). This condition can be eliminated by application of organic matterial to soil, because organic matter can increase the soil’s ability to hold water and soil fertility. Biochar as an organic material has been proved to increase soil water holding capacity and able to adsorb nutrients to prevent it from leaching. This research aimed to study the effect of combination of biochar and water supply on the availability of P in soil, uptake P by plants and yields of Turnip planted ini calcareous soil of Timor . This research is designed using Completely Randomized Design (CRD) and it is a single factor trial. There are 7 treatments of a combination of rice husk biochar dosage and volume of water supply. The results showed that there is a significant effect of the combination of rice husk biochar dosage and volume of water supply on the availability of soil P and the weight of radish tubers. Application of 300 gram.polybag-1 of biochar + 90% Etm of water supply gave higher available P (87,22 ppm), while application of 300 gram.polybag-1 of biochar + 80% Etm of water supply gave a better fresh weight of tuber (305,00 g ) compare to other treatments.

Abstract

This study aimed to detect the presence of key insect pests on corn in Muruona Village, Ile Ape Sub District, Lembata District in East Nusa Tenggara. This research was conducted from November 2020 to January 2021 on farmer's land in the region. This study used a survey method with direct observation techniques on corn plants, and sampling was carried out using sweep nets and sticky traps. The data collected included types of key insect pests, symptoms of damage, population, and intensity of damage to corn by important insect pests. The results showed three key insect pests on corn plantation in the study area: Locusta migratoria, Ostrinia furnacalis, and Helicoverpa armigera. This key pests were detected in corn from the early vegetative to the generative period. The symptoms of damage on corn caused by Locusta migratoria, Ostrinia furnacalis, and Helicoverpa armigera occurred six days after planting (DAP), 28 DAP, and 56 DAP, respectively. Symptoms of damage to corn plants caused by Locusta migratoria are tears in the leaves resembling serrations on the edges of the leaves, both young and old. Symptoms of damage to corn plants caused by Ostrinia furnacalis are grinding holes on the stems so that the stems so that the stem become damaged and then break. Grinding marks on the cobs and dirt and grinding powder characterize symptoms of damage to corn plants caused by Helicoverpa armigera. Populations of the key insect pests Locusta migratoria, Ostrinia furnacalis, and Helicoverpa armigera were very small, with 4, 3 and 1 insect, respectively. Moreover, for the highest intensity of damage to corn plants was caused by Ostrinia furnacalis, but it was categorized as light damage intensity because it was > 0 % ≤ 25%.

Abstract

Vertisol is a type of soil that has high in clay content, and generally has low organic matter content and available Nitrogen (N). This condition could be improved by the application of liquid organic fertilizer (LOF). One of the LOF that can be used is LOF made from washing rice waste water and egg shells. A polybag trial was undertaken to evaluate the effect of the application of LOF on some chemical properties of Vertisol and paprika yields (Capsicum annum var. grossum).The research was conducted from July to October 2020. The research was laid out in a Randomized Block Design consisting of 5 treatments namely P0; without LOF, P1; 50 ml LOF, P2; 100 ml LOF, P3; 150 ml LOF, and P4; 200 ml LOF. There were three replicates for each treatment. Data observed were analyzed using Analysis of Variance (ANOVA) followed by 5% DMRT. The observed data included total- N, available P, available K, number of fruit, and fresh weight fruit. The results showed that the application of LOF based on on rice wastewater and egg shell flour could improved soil chemical properties of Vertisols and yield of capsicum. The best treatment was at the application of 200 ml that contributed a good total - N, available P and available K as well as the highest number of fruit and fresh fruit weight of capsicum.

Abstract

To increase edamame production, one of the things to consider is the availability of nutrients, which can be provided through the addition of organic fertilizers, for example, trichocompost. Trichocompost plays a role in increasing crop production because it can increase soil fertility and contains the antagonistic fungus Trichoderma sp., capable of controlling plant pathogens. This study aimed to determine the growth response and yield of edamame due to the dose and time of application of trichocompost fertilizer. This research was carried out at the Undana Archipelago Dry Land Integrated Field Laboratory from October 2020 to June 2021. The study used a factorial randomized block design with two factors. The first factor was the dose of trichocompost (A), which consisted of four levels, namely A1=control, using the recommended NPK dose for edamame, which was 2.4 g/plant, A2=240 g of trichocompost/plant, A3=480 g of trichocompost/ plant, and A4=720 g of trichocompost/plant. The second factor was the application time of trichocompost (B) which consisted of three levels, namely B1 = application of trichocompost two weeks before planting, B2 = application of trichocompost one week before planting, and B3 = application of trichocompost at planting. Parameters observed were plant height, number of leaves, number of pods per plant, number of seeds, fresh plant weight, and seed dry weight. The results showed that the interaction between the doses of trichocompost fertilizer and the application time of trichocompost had no significant effect on all observational parameters. However, there was a tendency that trichocompost at a dose of 720 g/plant applied two weeks before planting had a higher number of pods, seeds, fresh weight, and dry weight of plants compared to the other treatments.

Abstract

This study aims to determine the preferences of the golden snail (Pomacea canaliculata L.). on several plants to determine alternative plants and host plants. This research was carried out in the Greenhouse of the Faculty of Agriculture, Nusa Cendana University, from March to May 2020. This study used a Completely Randomized Design (CRD) with four replicates and five treatments, so there were 20 experimental units. The treatments tested were plant types as feed: K1: mustard greens, K2: water spinach, K3: taro, K4: rice, and K5: water hyacinth. The initial weight of the feed was 50 g. The variables observed were the weight of the feed eaten every three days for two months and the development of the golden snail on each feed. The golden snail's development for each feed was observed in egg production, egg development, and longevity of the golden snail. Feed weight data were analyzed using variance followed by a 5% DMRT test. The golden snail's egg production, development, and longevity are presented in tables and described. The results showed that the feeding treatment of water spinach, mustard greens, taro, rice, and water hyacinth affected the eating preferences of the golden snail. Golden snail prefers to feed mustard greens than water spinach, taro, rice, and hyacinth. The golden snail produces eggs on water spinach and rice feed. The best golden snail reproduction was found on water spinach feed, which produces 1-3 groups of eggs, and the highest hatchability of golden snails was found on rice feed.
