This research was conducted at the Dryland Laboratory of Nusa Cendana University Kupang from September to December 2022. The purpose of this study was to determine the effect of interaction of doses of solid bokashi fertilizer made from a mixture of kirinyu and banana stem and hormonic concentration on the growth and yield of Cauliflower and determining the combination of those interaction that provides the best growth and yield of Cauliflower plants. This research was a factorial experiment, using Randomized Complete Block Design (RCBD) with three blocks and consisting of nine treatment combinations per blocks. The observed variables were plant height increse (cm), increase in leaves number, increase in stem circumference (cm), gross weight (g) and net weight (g). The observation data were analyzed by analysis of variance (ANOVA) and and followed by DMRT test (significant level 0.05%). The results showed that the interaction between the application of doses of bokashi and hormone concentration significantly affected the increase in height, increase in leaf number, and net fresh weight of cauliflower plants. The combination of treatment doses of bokashi at 10 tons/ha with a hormone concentration of 8 cc/L was the best interaction, with a net fresh weight of cauliflower plants reaching 265.71 g/ plant.

VARIABILITY AND GENETIC ADVANCE OF AGRONOMICAL CHARACTERS OF F2:4 LINES DERIVED FROM FORE BELU AND LOKAL SABU CROSSES

Mungbean is the third most important legume crop in Indonesia, and in East Nusa Tenggara Province in particular, as the crop is an important source of protein and vitamins, and also well adapted to dry land conditions of the province. However, the mungbean productivity in the farmer level is low, partly because of the use of low yielding local varieties. Mungbean productivity can be increased through the production of superior varieties, which can be done through artificial crossing using local germplasm. Crossbreeding between NTT local varieties has been carried out, between Fore Belu and Lokasl Sabu. This research aims to determine the variability of agronomic characters and the genetic advance of F2:4 lines resulting from Fore Belu and Lokal Sabu crosses. The research was carried out in the field involving 30 F2:4 lines and two parental varieties, each consisting of two replications. The variables observed included flowering date, harvesting date, plant height, number of pod cluster, number of pods, and seed weight per plant. Harvesting date had a narrow genetic and phenotypic variabilities while the other evaluated characters had wide/high variabilities. Heritability of all observed characters were classified high. Genetic advance of agronomic characters, especially the number of pods per plant, the number of productive branch per plant and the weight of seeds per plant were categorized as high. The F2:4 lines that showed desirable agronomic characters included G1, G7, G9, G21, G26, G27, G28, G29, G30, G32, G34, G35 and G39. These lines were selected for further testing in the F5 generation.

EFFECT OF SUCROSE CONCENTRATION AND CASHEW FRUIT PULP ON THE TOTAL FOOD FIBER, VITAMIN C, SUGAR CONTENT, AND WATER ACTIVITIES OF CASHEW JAM

ABSTRACT

This research aims to determine and obtain a combination of treatments of sucrose concentration and cashew fruit pulp on sugar content, vitamin C content, total fiber content and activity of water of cashew jam. The factor in this research is the combination of sucrose + cashew pulp (A) in making cashew jam. This research was designed with 5 (five) treatment combinations of sucrose concentration and cashew pulp, namely: A1 = 45% sucrose + 55% cashew pulp, A2 = 50% sucrose + 50% cashew pulp, A3 = 55 sucrose + 45% pulp cashew pulp, A4 = 60% sucrose + 40% cashew pulp, A5 = 65% sucrose + 35% cashew pulp. The variables observed were vitamin C content, total sugar content, total fiber content and activity of water (Aw). The research data were analyzed using descriptive statistical methods which included mean and standard deviation or standard error/SE. The research results obtained were the highest vitamin C content: 154.142 ± 2.692 mg in treatment A1 (45% sucrose + 55% cashew pulp), the highest sugar content: 76.843 ± 0.103% in treatment A5 (65% sucrose + 35% cashew pulp ), the highest total dietary fiber content: 2.199 ± 0.029% in treatment A1 (45% sucrose + 55% cashew pulp) and the lowest activity of water: 0.745 ± 0.014 in treatment A5 (65% sucrose + 35% cashew pulp).

EFFECT OF MYCORRHIZA ON BACTERIAL WILT DISEASE (Ralstonia solanacearum) IN TOMATO (Lycopersicum esculentum)

2024-07-27T15:47:53+00:00

Tomato plays an important role in Indonesian agriculture. Tomato production has been constrained by diseases, one of which was bacterial wilt (Ralstonia solanacearum). Application of Vesicular Arbuscular Mycorhiza (VAM) has been reported to be effective in suppressing diseases and can improve plant growth. This study was aimed to test the effect of VAM Glomus sp. in suppressing bacterial wilt disease on tomato (Lycopersicum esculentum). This research was conducted at Plant Disease Laboratory and Screenhouse of Agriculture Faculty, Nusa Cendana University. Seven treatments with three replications were arranged in Randomized Completely Block Design experiment. The treatments were 5 grams, 10 grams, and 15 grams of Glomus sp. per polybag that applied 1-week before pathogen inoculation, and also 5 grams, 10 grams, and 15 grams of Glomus sp. per polybag that applied simultaneously with pathogen inoculation. Control treatment was only inoculated with the pathogen. Three polybags, with two tomato plants planted in each were considered as one experimental unit. Ralstonia solanacearum was isolated from diseased tomato plant. Isolate pathogenicity was confirmed through hypersensitivity test on tobacco plants and on 21 day-old tomato plants. Two-week old tomato plants were inoculated with 15mL of suspension. The stem was punctured with sterile needle pryor inoculation. The result showed that Glomus sp. application before pathogen icoculation lowered disease incidence significantly. Application of 15 grams Glomus sp. before pathogen inoculation caused the greatest mycorrhizal vesicle formation in tomato root, which might also increased plant height and the number of leaves significantly.
