Abstract

The Effect of Spacing and Mulching of Rice Straw on Growth and Yield of Corn (Zea mays L.) Corn is the second staple food after rice in Indonesia. Corn as an energy source has advantages compared to other feed ingredients. This research aims to determine the effect of spacing and mulching of rice straw on the growth and yield of corn. This study used a randomized block design (RAK) with the allocation of factorial treatment. The treatment used consisted of 2 factors. (J1) spacing of 50 cm x 50 cm, (J2) spacing of 75 cm x 25 cm, (M0) straw mulch 0 tons/ha, (M1) straw mulch 10 tons / ha, (M2) straw mulch 20 tons/ha. Combination treatments obtained 6 treatments namely; M0 J1, M0 J2, M1 J1, M1 J2, M2 J1 and M2 J2. Each combination treatment was repeated 4 times, so there were 24 study plots. The treatment of spacing significantly affected the weight of dry seeds/m2, very significant on the number of fobs/m2, LAI (Leaf Area Index), fresh weed weight/m2 aged 8 and 12 mst. The spacing of 75 cm x 25 cm resulted in the weight of dry seeds/m2, which was 1.04 kg, which was 20% higher than the spacing of 50 cm x 50 cm 0.83 kg. Rice straw mulch treatment had a significant to very significant effect on the observed variables except 10 mst soil water content, leaf/plant chlorophyll content, number of cobs/m2, and ear diameter. Giving rice straw mulch 20 tons/ha resulted in dry seed weight/m2, which was 1.07 kg 33% higher than without mulch 0.72 kg. The interaction of plant spacing with rice straw mulch has a significant effect on LAI and is very significant on the weight of fresh weed/m2 ages 8 and 12 mst. The interaction of 50 cm x 50 cm spacing with 20 tons/ha rice straw mulch obtained the best results but was not significantly different from the treatment of 75 cm x 25 cm with 20 tons/ha of rice straw mulch.

Abstract

The Effect of Giving Various Kinds of Fertilizer on Growth and Yield of Gumitir Plants (Tagetes Erecta L.) Gumitir flower is one of the flowers used for ritual facilities by Balinese Hindus, besides it is used for tourism purposes. One of the efforts to increase growth and development as well as the quality of gumitir products is to provide adequate and balanced nutrient supply through fertilization. The purpose of this study was to analyze the effect of giving various kinds of fertilizer on growth and yield of gumitir plants (Tagetes erecta L.). This study used a Randomized Block Design with four replications and six treatments namely TP (without fertilizer), PG (Gandasil B fertilizer), PN (NPK Mutiara fertilizer), PU (Urea fertilizer), PB (Bio Urine fertilizer), and PS (fertilizer SP-36). The parameters observed were plant height (cm), number of branches per plant (fruit), time of flower buds appearing (days), fresh flower weight (g), diameter per flower (cm), number of fresh flowers per plant (grains), total weight of fresh flowers per plant (kg), fresh crop weight per plant (g), and oven dry perchart weight per plant (g). The results showed the type of fertilizer treatment gave a real effect on all observed variables. The NPK pearl fertilizer treatment yielded the highest total fresh flower weight per plant which was 2.15 kg, a markedly higher increase of 65.11% compared to the treatment without fertilizer and 53.48% compared with Bio Urine but not significantly different from the treatment of SP-36 fertilizer, Gandasil B fertilizer and Urea fertilizer.

Abstract

ABSTRACT Monitoring of Imago of Spodoptera litura and Helicoverpa armigera Using Sex Pheromone Trap The utilization of sex pheromone to control insect pest is one of advance technology. The sex pheromone is one method to control insect pests for support food security. In other to know the ability of sex pheromone to trap insect the monitoring of insect using sex pheromone is needed. The lure of sex pheromone, glue, and box trap were imported from AVRDC-The World Vegetable Center. Sex pheromone trap is putted on the vegetable area in Bali, the locations including Sandan, Kembang Merta, Candi Kuning (Tabanan Regence) and Pancasari (Buleleng Regence). On each location trap was placed with two replications. Data collection was conducted every week, on 3rd week observation the imago/moth population is completely reduce. Therefore the trap was replaced for the new trap. That mean the observation was conducted 3 times per experiment (Observation 1,2,3). In this case the experiments were done 2 times (Experiment 1 and 2). The identification of imago was base on the morphological method. The imago was accounted for data collection. The decrease of population of Spodoptera litura and Helicoverpa armigera after 3 week observation is possible caused by the ability of pheromone active ingredient is also decrease. The distribution of imago S. litura and H. armigera are same for all locations. However the total population of S. litura and H. armigera is different. The population of S. litura was very high in all locations around 51-107. However the population of H. armigera was generally low except in Sandan Tabanan (70). In Pacasari the population of H. armigera was lowest around 14-15. The differentiation of imago S. litura and H. armigera were possible influenced by the host plant, altitude and also climate conditions. Key worlds: sex pheromone, Spodotera litura, Helicoverpa armigira

Abstract

ABSTRACT Effect of Various Timing on Bud Cutting as Cuttings Material and Dosage of Rootone F on the Growth of Vanilla Short-Cutting (Vanilla planifolia Andrews) Vanilla (Vanilla planifolia Andrews) can generally be propagated by seed (generative) and vegetative by cuttings. As the multiplication by seed takes longer to flowering, thus the vanilla propagation for commercial purpose is done by cuttings. This study aims to determine the effect of time on bud cutting as cuttings material and dosage of Rootone F as well as its interactions on the growth of vanilla short-cuttings. This study uses two factors factorial design, i.e.: time on bud cutting as cuttings material and dosage of Rootone F. The result of the research showed an interaction between time on bud cutting as cuttings material and dosage of Rootone F provides a very significant effect on the variable of oven dried stems shoots weight, and showed a significant effect on the variable total oven dry weight; while other variables showed no significant effect. Treatment of time on bud cutting as cuttings material (P) showed highly significant effect on the variable of time to sprout, while the other variables showed no significant effect. Dosage of Rootone F (D) showed no significant effect on all variables. The interaction of time on bud cutting as cuttings material 8 days before planting with Rootone F dose of 100 mg / 1 ml of water provides a better growth of vanilla short-cuttings with the highest total oven dry weight is 1,12 grams and has increased 89.83% compared to the bud cut when the cuttings is about to be planted and Rootone F dose of 0 mg / 0 ml of water.

Abstract

Suitability of Irrigation Water Quality for Rice in Mambal Irrigation Area. Mambal irrigation area is located in southern region of Bali, close by urban area. It consists of 42 Subak which covered 4.820 ha. However, the total area that still exists today is only 2.978 ha, and it is considered potential in increasing rice production and supplying rice in order to support food self-sufficiency in Bali. The increase of population is considered as the factor of wetland conversion because, the growth of population leads to variety of purposes such as shelter (housing), tourism/hotel, accommodation, business/home industry, livestock, public facilities, etc. Therefore, the activities done on the wetland conversion area automatically changed. That activity on conversion area consequences in both liquid or solid waste, and it is often discharged into rivers or irrigation channels. Consequently, it may cause irrigation water pollution. Poor quality of irrigation water can endangering rice plant growth and reduce the production, which means blocking or inhibiting food self-sufficiency. This study is considered as field and laboratory research. There are some field activities done, namely observation of the pollution sources and types of pollutants, as well as waste disposal mechanisms and technologies used to tackle pollution. In order to determine the quality of irrigation water, the water samples taken in the primary channel (1 water sample), secondary channel (1 water sample), tertiary channel (1 water sample), and field area (3 samples of water). All water samples are analyzed at the Analytical Laboratory of Udayana University. The results of the study are the sources of pollution come from channel natural environments, public facilities, housing and household waste. It was found that there are some types of waste, namely natural garbage, artificial garbage, liquid or solid waste in small amount. The mechanism of waste disposal is done conventionally and there is no application of technology of waste disposal. The outcome of the study is irrigation water quality for rice is still suitable for irrigation.

Abstract

The Application of High Puddle and Organic Fertilizer on Rice Yield Ciherang Variety. Rice (Oryza sativa L.) is the staple vital food of Indonesian people. National rice production has not been able to meet the needs of the population, despite many efforts such as the use of improved varieties, fertilization, the use of agricultural machinery, and the use of pesticides. This study aimed to determine the effect of water level and organic fertilizers on crop yields of rice. This experiment used randomized block design in a simple treatment, namely the combination of the water level and the dose of organic fertilizer. This research using analysis of variance (ANOVA) to determine the effect of treatment on the variables tested. If treatment significant it will be followed by LSD test 5%. The results showed that the treatment of combination of water level and organic fertilizers provide a very real effect on the growth and yield of rice (Harvest dry grain yield ha-1). Harvest dry grain yield ha-1 obtained at the highest AMP2 treatment, namely without flooding water and organic fertilizers and 6 t ha-1 at 10.92 t ha -1 were significantly higher 70.09 % compared to the treatment of farmers. Based on the research results, it can be recommended that the application of water-saving cultivation of organic fertilizer with a dose of 6 t ha -1 needs to be done to improve rice yields.
