The purpose of this research was to evaluate the behavior per se of elephant grass (Pennisetum purpureum Shum) hybrids for energy purposes by means of morpho-agronomic traits in four evaluation sections. An experiment in randomized block design with three replicates was applied to evaluate the hybrids. The plot consisted of a 15-m row with 1.50-m row spacing, and 1.50-m spacing between plants. The usable area was composed of the five central plants. It was evaluated Number of tillers per clump; Stem diameter; Plant height; Plant dry matter yield; and Percentage of dry matter. Computational resources from the GENES Program were used to analyze the results. In both cuts, the H7, H11, and H14 hybrids was superior to the others in the four evaluation cuts for all evaluated characteristics, proving to be a potential genotype to be used for energy biomass production.

Liquid organic fertilizer with the right concentration is expected to be a source of nutrients for the growth of mini elephant grass. The aims of this study were to determine the effect of liquid organic fertilizer with different concentrations of urine and Local Microorganism (LMO) on the production of mini elephant grass. The research method used was a randomized block design (RBD) with 4 treatments and each treatment consisted of 3 groups as replications. The treatments used were liquid organic fertilizer, with concentrations of P0 (as a control), P1 (100 % urine, 0 % LMO), P2 (90 % urine, 10 % LMO) and P3 (85 % urine, 15 % LMO). The results showed that liquid organic fertilizer with different concentrations of urine and MOL had no significant effect on plant height, number of leaves, number of tillers and production of fresh weight (g/clump). The liquid organic fertilizer with different urine and MOL concentrations has no significant effect on the growth and production of mini elephant grass.

Clove oil has the potential to suppress the development of the mosaic virus in patchouli plants, but its effectiveness in the field has not been studied. This study aimed to evaluate the effect of clove nano biopesticide on controlling patchouli mosaic disease. The research was conducted at the Manoko Experimental Garden, Bandung, West Java from March to November 2018. The patchouli used was Patchoulina-2 variety, which originated from the Seed Breeder Garden in Lembang, Bandung.  This study was arranged in a Randomized Block Design (RBD), consisting of five treatments and ten replications within each treatment, with one hundred plants in each replication. The results obtained showed that nano biopesticides of citronella, clove, and commercial citronella (Asimbo) were able to reduce the incidence and intensity of mosaic diseases in patchouli plants, showing the efficacy levels of 14.68%, 9.06%, and 5.83%, respectively. The application of citronella and clove biopesticides on Patchoulina-2 every month could increase plant fresh weight, when compared to the plants without treatment. Patchoulina-2 plants treated with nano biopesticides of clove and commercial citronella (Asimbo) showed higher value of fresh weight compared to those treated with citronella nano biopesticide. The clove nano biopesticide can also be developed to control mosaic diseases in patchouli plants.

The productivity of chili in terms of both quality and quantity is suppressed by the attacks of anthracnose disease caused by Colletotrichum spp. Pesticides is commonly used to control the disease. Researched was conducted to determine the antagonistic fungi and the effective dose in inhibiting the growth of the Colletotrichum spp. Antagonistic tests were performed in vivo using the direct method with three replicates. Inhibition test was arranged in a Complete Randomized Block Design (RCBD) with 7 treatments: Control, Gliocladium sp (150, 250, and 350 mL/plant) and T. harzianum (150, 250, and 350 mL/plant) with four replicates and three samples out of 20 plants per treatment. The results showed that the percentage of inhibition of T. harzianum against Colletotrichum sp. is 55% while Gliocladium sp. is 70.33% in antagonistic test. The mean of disease intensity at 11 up to 32 DAI on control is 5.61 ± 0.71% up to 20.30 ± 1.35 % respectively. It is significantly higher than Gliocladium sp. 350 mL/Plant (1.94 ± 0.45 % up to 11.15 ± 0.87 %), T. harzianum 350 mL/Plant (1.10 ± 0.58 % up to 8.68 ± 0.91 %), and T. harzianum 250 mL/Plant (2.28 ± 0.43 % up to 8.75 ± 0.79 %). No significant different is observed on mean of fresh weight of red chili fruit yield per plant. T. harzianum and Gliocladium sp. fungi are effective in controlling the attack of anthracnose disease in chili. The most efficient dose to control anthracnose disease is the application of T. Harzianum or Gliocladium sp at the dose of 250 mL/plant.Key Words: Chilli, Anthracnose, Gliocladium, Trichoderma, Colletotrichum.

The study aimed to determine the effect of organic planting media and the position of seed planting on the growth of Robusta coffee seedlings. The study is conducted at the Tabanan Agrotechnology Study Program, Tabanan University, which conducted from July 2019 to September 2019. The treatments are arranged in factorial in a randomized block design (RBD). Two treatments examined in this study were the doses of organic matter in the growing media (0g, 150 g, 300 g, 450 g) and seed position (prone position, upside down, tilted position). The results show that the interaction between organic planting media (soil + coffee leaf compost) and seed planting position did not significantly affect all coffee seedlings growth variables. The dose of organic compost in the growing media has a very significant effect on all growth variables except when growing and the percentage of growth. The dosing of 450 g organic matter gave the highest root fresh weight, fresh stem weight and fresh leaf weight (1.00 g, 2.97 g and 8.64 g respectively) and oven dry weight for the three variables (respectively 0.39 g, 0.55 g and 1.36 g). Seed planting position has no significant effect on all observed variables, but there is The tendency of planting position with the prone on average gives better growth compared to other positions.

ABSTRACT A balanced periodicity of the nutrient solution flow is essential for better agronomic performances and low production costs in hydroponic systems. Thus, the objective of this work was to evaluate the effect of periodicity of exposure of lettuce plants to the nutrient solution in an NFT hydroponic system on the production, nutrition, and profitability of this crop. The experiment was conducted in a randomized block design with five replications. The treatments consisted of four periodicities of exposure of lettuce plants to the nutrient solution, consisting of intervals of 60, 30, and 15 minutes between pumping periods of 15 minutes; and uninterrupted flow of the nutrient solution. The plants were harvested at 30 days after transplanting, and 15 lettuce plants of each experimental plot were used to determine total fresh weight; root fresh weight; shoot freshweight; and contents of N, P, K, Ca, Mg, S, B, Cu, Fe, Mn, and Zn in shoots, roots, and in the diagnostic leaf; accumulation of these nutrients in shoots and roots; and nitrate and ammonium contents in plant shoot. The highest production and profitability of lettuce were found using uninterrupted nutrient solution flow, which provided higher shoot and root nutrient contents to plants, and resulted in a better nutrient use efficiency.
