Abstract

Exploration, Identification and Study of Flowering and Fertilization Phenology of Salak Cultivars in Bebandem District, Karangasem, Bali. Salak in Bali is one of the most popular fruit plants and widely developed in Bali. This study aimed to identify the types of zalacca cultivars in Karangasem Regency, compiled the profile of plant genetic resources concerning morphological and agronomic characters, photographs of genetic resources as well as the flowering and fruiting phenology of salak cultivars. The research was conducted in Bebandem District, Karangasem Regency, from December 2019 - April 2020. The research was consisted of 5 (five) stages, i.e.: (1) collected secondary data, (2) collected primary data, (3) identification the morphology and agronomy characters, (4) phenology studies of flowering and fertilization and (5) tabulation and data analysis. The results showed that there were 12 types of salak cultivars in Bebandem District, with different phenology of flowering and fertilization for each cultivar. Based on the agronomic characters, the most superior salak cultivated include salak gula pasir (Salacca zalacca var Gula Pasir), salak gondok (Salacca zalacca var Gondok) and salak nangka (Salacca zalacca var Nangka).

Abstract

This study aims to determine the actual and potential land suitability, limiting factors, provide land use direction and create a land suitability map for horticultural crops in North Denpasar District. This study uses field survey methods, soil analysis at the Laboratory of Soil and Environmental Sciences, Faculty of Agriculture, Udayana University, and the matching method. Observation of sample points was carried out by purposive sampling in each subak. Sampling was carried out to a depth of 30 cm. The results showed that the actual land suitability class for horticultural crops (sweet potato, potato, chili, tomato and eggplant) was classified as S3 (marginally appropriate) to N (not suitable) with the limiting factors being temperature, rainfall, N-total, K2O, and erosion hazard. Improvement efforts can be made by giving organic matter, giving Urea and KCl fertilizer. Potential land suitability classes for horticultural crops are classified as S3 (marginal appropriate) to N (not suitable), with temperature and rainfall limiting factors. The types of plants recommended for Subak Dalem, Kedua, Lungatad, Pakel II, Petangan, Ubung, and Sembung are sweet potatoes, chilies, tomatoes, and eggplants. The types of plants recommended for subak Pakel I are chili, tomato, and eggplant.

Abstract

This study aims to determine the quality of paddy soil, to determine the limiting factors of paddy soil quality, to provide land management direction in an effort to improve the quality of paddy fields and to make soil quality maps. This research was conducted in Nort Denpasar District from December 2020 to February 2021. Soil quality evaluation was carried out using field survey methods and laboratory analysis. Soil quality evaluation data analysis was carried out by matching and scoring based on limiting factors of 10 minimum data set (MDS) determinant of soil quality rating (SQR). The results showed that the soil quality in the study location was classified as moderate to good soil quality. Soils with moderate soil quality are found in SLH 3 and SLH 4 while soils with good soil quality are found in SLH 1 and SLH 2. The factor limiting soil quality in the study area is the low N and C-biomass. Based on the results of the study, the management directions at the research location can be determined, namely by adding organic matter, fertilizing urea, setting cropping patterns and applying intercropping.

Abstract

Vanilla (Vanilla planifolia Andrews) is a plants that has fruit with high economic value. The purpose of this study was to determine the concentration of Rootone F, types of growing media, and their combination to increase the success of one segment propagation of vanilla. This research was conducted from December 2020 to March 2021, located in Melinggih Kelod Village, Payangan, Gianyar. This study used a factorial randomized block design (RBD). Factor I: concentration of Rootone F which consists of concentrations 0 ppm (R0), 750 ppm (R1), 1.500 ppm (R2), and 2.250 ppm (R3), factor II: type of planting medium consisting of soil (T), soil + husk charcoal (TA), soil + cocopeat (TC), and soil + compost (TK) which was repeated 3 times. The concentration of Rootone F 2.250 ppm caused the highest total dry weight (4,30 g) or 49,31% higher than the 0 ppm treatment. The type of planting media soil + compost media caused the highest total dry weight (4,06 g) or 28,07% higher than the soil treatment. The combination of 2.250 ppm Rootone F with soil media + compos caused the highest total fresh weight of 85,07 g or 95,20% higher than 0 ppm Rootone F with soil media.

Abstract

This aims of the research is to search the abudance of T. parvispinus Karny and its natural enemies on Cayenne Pepper (Capsicum frutescens.L). The research started from November 2020 to January 2021 at Melinggih Kelod Village, Payangan District, Gianyar Regency and at the Plant Pest Laboratory, Faculty of Agriculture, Udayana University. The study was conducted using a descriptive method by conducting a diagonal survey of 20 samples of cayenne pepper that were attacked by T. parvispinus. Observations were made by observing 10 leaves and 10 flowers of cayenne pepper plants. The results showed that the abundance of T. parvispinus in the vegetative and generative phases fluctuated where the highest population of T. parvispinus occurred in plants aged 10 week after transplanting with an average population of 15.8 individuals per plant then decreased in plants aged 11 WAT with an average population 9.75 individuals. The results showed that there were two types of predators that preyed on T. parvisvinus, namely Chrysoperla carnea with an average population of 23.3 and Coccinela transversalis with an average of 22.4 individuals. Laboratory reseach showed that the type of parasitoid that emerged from the 100 nymphs that were caught was Ceranisus spp with an average population of 10.2 individuals.
