Abstract

This study aims at finding out the PGPR dose on the growth of cocoa seed and investigating the optimum dose of PGPR that can grow cocoa seed. A random block design was employed in this study with the treatment of 7,5 ml PGPR seed-1 (PG 1), and PGPR 15 ml PGPR seed-1 (PG 2), the PGPR dose of 30 ml PGPR seed-1 (PG 3), and PGPR 45 ml PGPR seed-1 (PG 4). The result of this research indicates that the treatment of PGPR dose has an apparent influence on the growth of the cocoa seed. The better cocoa seed growth is that the plant height improves to 5,26%, leaves a total number of 5,64%, leaves width of 8,36%, the diameter of stem increases to 12,00% mm, the weight of wet fresh stover plant-1 rises to7,69% and dry weight of stover plant-1increases to 10,71%. The optimum dose of PGPR for cocoa seeding is 45 ml PGPR seed-1.

Abstract

The study aims at revealing the impact of Tiens Golden Harvest organic liquid fertilizer on the growth and the yield of clove seed and optimum dose of Tiens Golden Harvest liquid fertilizer leading to the growth and the optimal yield of clove seed. The design used in this study was random block design with the treatment of T0 = Tiens Golden Harvest fertilizer 0 g/seed T1 = Tiens Golden Harvest 45 ml/seed, T2 = Tiens Golden Harvest fertilizer 90 ml/seed, T3 = Tiens Golden Harvest fertilizer 135 ml/seed, T4 = Tiens Golden Harvest fertilizer 180 ml/seed. Observation variables in this study were plant height, total leaves, leaf width, total fresh weight of brangkasan plant-1 and total dry oven weight of plant-1. The analysis result indicated that giving a different dose of Tiens Golden Harvest fertilizer may impact the plant height of 44,27%, fresh weight of plant-1of 32,58%, dry oven weight of plant-1of 48,92%. The optimum dose of Tiens Golden Harvest fertilizer contributing to the optimal growth of the clove seed is 180ml seed-1.

Abstract

The study of the quality profile of plantation excellent commodity in Ende Regency (hazelnut commodity) is to provide information about the degree composition of water and fat on hazelnut commodity in Ende Regency. Hazelnut commodity profile benefits for the provision of trade opportunity information and the investment of hazelnut cultivation to both foreign and domestic investors, as well as business persons, in order to boost the investment growth in Ende Regency. This study was conducted in the Agriculture Technology Laboratory of the Udayana University of Denpasar. The presentation of hazelnut commodity profile in EndeRegency of East Nusa Tenggara Province apparently reveals that this region has great potential to be further developed viewed from the quality content aspect.

Abstract

This study aims at exploring and identifying parasitoid Plutella xylostella pest on cabbage plants Brassica oleracea in Nduaria Village and finding out the most dominant parasitoid associated with Plutella xylostella pest. Observation variables used included identification of parasitoid species being parasitic in each stage of Plutella xylostella pest life found in the field, parasitoid species abundance and domination of parasitoid. The result of exploration in three sub-villages of NduariaVillage indicated that there were three species of the parasitoid, namely eggof parasitoid Trichogrammatoidae cojuangcoi, the larva of parasitoid Diadegma semiclausum and Cotesia Plutellae. The dominant parasitoid is Diadegma semiclausumwith the value of 0,11. The most abundance in parasitoid larva Diadegma semiclausum is 5,7%. Damage intensity caused by Plutella xylostella was categorized as medium damage intensity of>25-?50%, and this kept rising along with the age of larva and population as well as supporting environment condition due to Plutella xylostella resistance to the pesticide.

Abstract

This study aims at revealing the impact of plant media on the growth and yield of white oyster mushroom (Pleurotusflorida) and finding out what plant media that can give the optimal growth and yield. The design uses in this study was random block design with the treatment of Mbayam (Bayam wood powder), Mmeranti (Meranti wood powder), Mkemiri (Hazelnut wood powder), Mjerami (straw). The observation variables used in this study were the prime emergence of the fruit, the number of fruit clumps, number of fruits per clump, harvesting age, the diameter of fruit, the length of fruit stalk, harvesting interval, the weight of the fruit, and REB value. The result of the study indicated that straw planting media was not able to grow mushroom and was contaminated. Planting media of bayam wood powder with Meranti wood powder, Bayam wood powder with hazelnut wood powder, and Bayam wood powder with straw makes a difference respectively, as follows: the primary emergence of fruit was 54:58 HST, 54:57 HST, and 54:0 HST, the number of fruit clumps were18,1%, 28,8%, and 100%, the number of fruit per clump were 4,0%, 13,9%, and 100%, and harvesting age were 4,1:4,9, 4,1:4,1, and 4,1:0. Planting media of Bayam wood powder provided the high average in the primary emergence of the fruit of 54 HST, 118.7 of fruit clumps, 15.1 of fruit/clump,6cm of fruit diameter, 2.9cm length of fruit stalk, 6.6 days of harvesting interval, 68.9gram of fruit weight and 0.68 of REB value.

Abstract

This study aims at investigating the content of cadmium on carrots, leeks, and string bean grown on limestone and volcanic soil with different dose of P Fertilizer and comparing the contents with cadmium content standardized by FAO/WHO. This pot test employed random block design and was a factorial test with three factors, namely factor of plant species, soil type, and fertilizer dose with three repeated tests. The levels of each factor are plants species consisting of Carrot (C1), leek (C2), and string bean (C3); soil type comprises of Andosol Nduaria (S1), MollisolFatumnasi (S2), VertisolOesao (S3) and MollisolBaumata (S4) and the fertilization consists of three levels of P fertilizer, namely 100 kg SP-36 per ha (F3), 50 kg SP-36 per ha (F2) and without P fertilizer (F1). The result of this study shows that the prediction model of cadmium content on the carrot, leek, and string bean based on cadmium, pH, electricity power, and land organic C content cannot be revealed in this study since the cadmium content cannot be detected by AAS. Moreover, the cadmium content on the carrot, leek, and string bean planted on four soil types and given different doses of P Fertilizer are under the standard set up by FAO/WHO (<0,05-01 mg kg-1).

Abstract

This research is aimed to find out the preference of cocoa pod borer to diameter, biophysical, and biochemistry cocoa pod; the percentage of infested pods, percentage of seed damaged, and percentage of yield lost. In addition, this research is also aimed to assess the effect of plastic thickness on cacao pod rot disease, the effect of sheathing on the black ant and mealybug populations on pods. This research was conducted at Selemadeg District, Tabanan Regency from October 2009 until January 2010. The field trial was arranged into randomized complete block design (RCBD) by 15 treatments were sheathing with various thickness of plastics (S0-S4) and cocoa pod diameters (B1-B3). The results indicated that, based on the percentage of the infested pod, cocoa pod borer has preferred the fruit with diameter > 4.5-7.5 cm. This condition may be contrasted, the smallest pod size (3,5-4,5 cm) was the healthiest pod, even though it contains more nutritionally compound. The smaller pod rot disease in red and green types. Sheathing by plastic of > 0.02 mm thick in medium size of pods was the most effective to prevent cocoa pod borer infestation. Sheathing with plastic was not affecting the population of both black ants and mealy bugs. Based on these results, it can be suggested that sheathing with plastic of > 0.02 mm thick on medium size of the pod is promising control measure to prevent yield lost caused by cocoa pod borer and cocoa pot rot disease.
