Abstract

The Effect of GA3 Concentration on The Induction of Grapevine (Vitis vinifera L.) Shoots Grown In Vitro The research concerning ‘The Effect of GA3 Concentration on the Induction of Grapevine (Vitis vinifera L.) Shoots Grown In Vitro’ have been conducted during period of February to August 2016 at The Laboratory of Plant Tissue Culture, Faculty of Agriculture, Udayana University. The objective of the research was to find out the most appropriate concentration of GA3 in stimulating of grapevine shoot grown in vitro. The experiment was laid out in a Completely Randomized Design with 5 treatments of GA3 concentration. The treatments were 0, 10, 20, 30, 40 ppm of GA3, each was replicated five times. The results showed that the treatment of 20 ppm GA3 was the most appropriate concentration in stimulating growth of grapevine shoots. The highest percentage of explants growing shoots i.e. 33.3% was obtained with the treatment of 20 ppm of GA3, compared to 6,6% (0 ppm), 0% (10 ppm), 20% (30 ppm), 6,6% (40 ppm).

Abstract

The Impact of Chemical Fertilization, Organic, Mineral, and The Combination of Fertilizer towards the Production Number and Quality of Sweet Corn (Zea mays saccharata Sturt.) in Inceptisol Experimental Garden Agriculture Faculty of Udayana University The study aims to figuring out the used of some fertilizers in order to increase the production and the quality of sweet corn in Inceptisols area, and also for figuring out chemicals characteristic and soil fertility in Pegok Village, Denpasar. This research was conducted on August until November 2016, the research took place in the Experimental Garden Faculty of Agriculture, and Soil Laboratory and Environmental Sciences, Faculty of Agriculture, Udayana University. The design method was used for this research was a randomized complete block resign (RCBD) using seven treatments and three-time repetition with the number of plots 21 consist of P0 = Control, P1 = Organic fertilizer, P2 = Mineral fertilizer, P3 = Chemical fertilizer, P4 = Combination Fertilizer (PO + PK), P5 = Combination Fertilizer (PM + PK), P6 = Combination Fertilizer (PO + PM + PK). When the result of variance statistical test shows different result, the procedure followed by LSD method (Least Significance Different) with 95% of confidence level using Costat program.The result of statistical analysis shows the role of chemical fertilizers was proven ability to increase the sweet corn production number, the highest result was 13,97 tons ha-1 which use the P3 treatment (200 kg Phonska and 200 kg Urea) ha-1 increased 110,08%, it showed a better result compared to P0 (Control) which only showing 6,65 tons ha-1. The best quality of sweet corn was shown by P6 formula: the combination of organic, chemical and mineral fertilizer.

Abstract

Analysis of Water Carrying Capacity For Domestic Clean Water Needs in Gianyar and Ubud District of Gianyar Regency Water is the main needs used sustainably. The needs of water always increases in line with the growth of the human population. The increase of water needs for domestic compels a region to maintain the availability of water in order to support the clean water needs. The aim of this study was to found out the water carrying capacity to fulfill the need of clean water of domestic in Gianyar and Ubud sub-districts, Gianyar regency. The research was done using descriptive quantitative method and to determine the number of respondent using stratified random sampling method. The water needs for domestic in Gianyar sub-district is 2,671,391.2 m3year-1 and the potency of water availability was calculated based on the surface water is 513,232.9193 m3year-1; groundwater recharge is 653,205.5337 m3 year-1; and the groundwater basin is 22,000,000.16 m3 year-1. The water needs for domestic in Ubud sub-district is 2,111,598 m3 year-1 and the potency of water availability was calculated based on the surface water is 476,395.4871 m3 year-1; groundwater recharge is 582,261.1509 m3 year-1; and the groundwater basin is 18,000,000.99 m3 year-1.Carrying capacity index of surface water in Gianyar sub-district is 0.19; groundwater recharge is 0.24 and the groundwater basin is 8.23. Carrying capacity index of surface water in Ubud sub-district is 0.22; groundwater recharge is 0.27; and the groundwater basin is 8.52. Based on the analysis, it was found that the status of surface water and groundwater recharge carrying capacity in Gianyar and Ubud sub-district was deficit (water supply < water demand), however carrying capacity of groundwater basin was surplus (water supply > water demand).

Abstract

The Combined Effect of Plant Spacing and Varieties on the Growth and the Corn Yields (zea mays l.) at Loes, Sub District of Maubara, District of Liquisa Repupublica Democratica De Timor Leste Plant spacing will affect the density of plant, efficiency of light use, the competition of plants in the use of water and nutrients, and finally will affect the production of plants. Each variety of corn crops requires planting distance suitable for optimal growth and maximum yield. This study aims to determine the best combination of plant spacing and corn varieties in yielding optimal growth and highest yield. The study used Randomized Block Design (RAK) with nine treatments and three replications. The experimental treatments were: a combination of plant spacing of 50 cm x 40 cm and Sele varieties; combination spacing of 50 cm x 40 cm and Noimutin varieties; combination of plant spacing of 50 cm x 40 cm and Nai varieties; combination spacing of 75 cm x 25 cm and Sele varieties; combination spacing of 75 cm x 25 cm and Noimutin varieties; combination spacing of 75 cm x 25 cm and varieties of Nai; combination spacing of 80 cm x 25 cm and Sele varieties; combination spacing of 80 cm x 25 cm and Noimutin varieties; and the combination of plant spacing of 80 cm x 25 cm and Nai varieties. The results showed that the combination of plant spacing of 75 cm x 25 cm and Nai varieties produced the best growth of corn plants, with the highest leaf area (286.35 cm2) and the highest stem diameter (2.787 cm). The highest dried seeds of 13% were found in the same treatment with an average value of 149.60 g per plant and 7.78 tons per hectare.
