Abstract

Determination of Harvest Time for Quality Seed Production of Long Bean Plants (Vigna sinensis L.). Seed maturity generally occurs at the same time as fruit maturity. When the fruit reaches its physiological level, it is the best time to get seeds with high quantity and best quality. Early harvest before physiological maturity many seeds have not been completely filled so that they will produce low quality seeds because many seeds are wrinkled. Meanwhile, when harvested after physiological maturity, the seeds experience weather conditions so that many seeds experience physical and physiological quality deterioration. The research aimed to get the right harvest time in the production of quality seeds of long bean plants. This study used a randomized block design with 6 treatments at harvest pods after blooming and 4 replications. The six treatments were harvest age 14, 17, 20, 23, 26, and 29 days after the flowers bloom. The results showed that the right time to harvest pods for the production of long bean seeds was 26 days after blooming, the color of the pods has changed from green to yellow, the seeds have the highest dry weight (7,56 g), the best germination capacity (100%), and maximum vigor (88,78%).

Abstract

The Application of Natural Gibberellic Acid (GA) from Bamboo Shoot Extract to Increase Quality of Tomato (Lycopersicum esculentum Mill). Tomato is a horticultural plant that has a lot of benefits. To increase the quality and productivity of tomatoes can be done by giving plant growth substances. This research aimed to find out the effect of natural gibberellic acid (GA) from bamboo shoot on the quality of tomatoes and to get the best natural gibberellic acid concentration from bamboo shoot to increase the quality and productivity of tomatoes. This research was designed using Randomized Block Design which consisted of 1 factor that is natural hormone concentration from bamboo shoot, with 5 treatments. Every treatment was repeated for 5 times. The standard of the treatment consisted of K0 as a control, K1 which was sprayed by 25% of bamboo shoot extract concentration, K2 which was squirted by sprayed by 50% of bamboo shoot extract concentration, K3 which was squirted by 75% of bamboo shoot extract concentration, and K4 which was sprayed by 100% of bamboo shoot extract concentration. The bamboo shoot was sprayed before the tomatoes’ flower blossomed. This research found that the application of bamboo shoot extract affected the quality of the tomatoes itself and reduced the number of seeds of tomato itself. In conclusion, the best concentration that can reduce the number of tomatoe’s seeds is the concentration of 75% (K3) compared to control one with 77%.

Abstract

Predation and Functional Response Test of Predator Chysoperla carnea Stephens (Neuroptera: Crysopidae) Against Phenacoccus manihoti Matile-Ferrero (Hemiptera: Pseudococcidae). This study aims to evaluate the predatory capacity of C. carnea by measuring the rate of searching capacity and handling-time of one prey and its functional response to the population density of P. manihoti. The research was conducted at the Integrated Pest Management Laboratory (IPMLab), Faculty of Agriculture, Udayana University. The study was conducted from February to May 2019. Testing of functional responses used a randomized block design with 5 treatments (3, 6, 9, 12, 15 nymphs-3) each of which was repeated 10 times. The results showed that the prey searching-capacity when the population was low (3 nymphs-3) took longer (10.37 minutes), while when the population was high it took a short time (6.23 minutes). The length of time for handling one prey in the low population was 6.08 minutes, while in the high population it was 5.48 minutes. Predator C. carnea has a tpe-2 functional response to an increase in the population of P. manihoti nymphs with the equation Y = 4.32x / 1 + 1.973x (R2 = 0.980). The rate of predation increases sharply when the population of low increases, and decreases when the increase of prey population increases. C. carnea has the potential to be developed as a control agent for P. manihoti.

Abstract

Database of Sustainable Food Agricultural Land Resources Based on Remote Sensing and Geographical Information System at Subak Temaga East Denpasar Subdistricts. Subak Temaga doesn’t yet have a database according to Government Regulation No. 25 of 2012 concerning Information System for Sustainable Food Agriculture Land (SFAL). A geospatial-based database needs to be compiled to implement these regulation. The research aims: compile a database of artificial resources, agricultural resources, land resources and human resources to support SFAL in Subak Temaga, create land ownership maps in Subak Temaga, compile an information system of SFAL and land ownership based on remote sensing and Geographic Information System (GIS). This research uses a survey method to obtain primary data, then doing the mapping to compile the information system based on geospatial. The research results: artificial resources (irrigation, jogging track/farm road), land resources (soil family, landform, slope, rainfall, land suitability, soil fertility), agricultural resources (types of farm commodities, productivity, agriculture tools and machinery, cropping pattern, types and dosage of fertilizer), human resources (name, address, age, last education, farmer status, ownership status, ownership large and boundary, profit-sharing system). Farmer status consists of 56 owner farmers (30,9%) and 125 sharecropers (69,1%). Land ownership status consist of 432 freehold polygons (92,7%) and 34 non freehold polygons (23.8%). Remote sensing is used to determine the boundaries of land ownership, GIS is used to compile a geospatial-based information system for LP2B and land ownership.

Abstract

Differences in Height, Number of Leaves, and Stem Diameter of Corn (Zea mays L.) in Alley Cropping and Intercropping of Agroforestry Systems at the Micro Watershed of Tukad Sumaga Village, Gerokgak District, Buleleng Regency. Degraded land as a result of land conversion has a very bad impact on the agro-ecosystem. Land conversion caused by the increasing needs of the population. The majority of the livelihoods of the people in Tukad Sumaga village are farmers. The availability of forage is very important to be maintained. Corn plants, in addition to their production in the form of corn, forage fodder on corn plants are very important for the availability of cattle feed. This research was conducted on 28 DAP maize (Zea mays L.) in alley cropping system and intercropping in the micro watershed of Tukad Sumaga Village. The results showed that the highest average plant height, leaf number, and corn stalk diameter were found in the alley cropping system namely 1.03 m, 7.31, and 1.59 cm. There was no significant difference between the height of corn plants in alley cropping and intercropping systems. There is a significant difference between the number of leaves and the diameter of the stems of maize in alley cropping and intercropping systems.

Abstract

The Effect of the Mount Agung Volcanic Ash and Compost on Soil Properties and Yield of Tunggak Nuts (Vigna unguiculata (L.) Walp). The purpose of this study was to determine the effect of giving volcanic ash and compost as a soil amendment. The design used was a factorial randomized block design. The volcanic ash factor consisted of 3 levels: A0 = no volcanic ash, A1 = 15% volcanic ash and A2 = 30% volcanic ash. The compost factor consisted of 3 levels: K0 = without compost, K1 = 10 tons of compost ha-1, and K2 = 20 tons of compost ha-1. The combination treatments was repeated 3 times so that there were 27 observation units. Several parameters of soil properties and yield of tunggak nuts were studied to determine the effect of volcanic ash and compost as soil amendments. The results showed that the interaction between the treatment of volcanic ash and compost on the soil and plants was not significant, while the single treatment of compost had a significant effect on the growth and yield of tunggak nuts. The treatment of volcanic ash has not shown a significant effect, both on soil and on plant growth and yield.
