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.

Chromolaena odorata (L.) is a potential compost since it has high biomass and contains calcium, manganese, potassium and nitrogen. The aim of this research was to know the potency of siam weed Chromolaena odorata compost on soil chemical and chili plant performance. The experiment was arranged in factorial randomized block design consisted of two factors and three replications. The first factor was variety of fertilizer (no fertilizer, cow manure, siam weed compost and inorganic fertilizers) and the second one was the tanglefoot (with and without tanglefoot). Overall, the results of study showed that C. odorata compost could increased crop performance when compared with the other fertilizers in terms of number of fruits, fresh/dry weight of fruits, dry weight of crops, and N-total (leaf, stem, root and fruit), though there was no difference in fresh weight of crops among treatments. Furthermore, the effect of siam weed compost was not significantly different on soil chemical if compared with all treatments. This study is likely suggesting that C. odorata compost gives a positive effect to crops performance and soil chemicals.Keywords:  Chili, Chromolaena odorata, compost  fertilizer, tanglefoot

Aims: This study aimed to optimize the levels of gibberellic acid (GA3) and plant spacing on growth and yield of lettuce. Study Design: The experiment was laid out in Randomized Complete Block Design with three replications. Place and Duration of Study: Horticulture farm of Sher-e-Bangla Agricultural University, Dhaka-1207, from November 2013 to January 2014. Methodology: The experiment consisted of two factors. Factor A- two levels of gibberellic acid (GA3,) application, viz. G1= 25 ppm and G2= 50 ppm in relation to a control G0 and factor B- four plant spacing viz. S1=15cm x 15cm, S2=20 cm x 20 cm, S3=25 cm x 25 cm and S4=30 cm x 30 cm. GA3 was applied twice as a foliar application by hand sprayer at 20 and 30 days after sowing. First, second and final harvesting was done at 25, 35 and 45 days after sowing respectively. Results: The growth and yield characters of lettuce showed significant variation for different levels of GA3 and plant spacing. Among GA3 levels, 25 ppm GA3 produced the maximum number of leaves (15.6), leaf area (283.9 cm2), fresh weight (91.6 g plant-1), dry weight (11.8 g plant-1), fresh yield (1794 g plot-1) and gross yield (12 t ha-1) at final harvesting compared to control where GA3 was not used. Under plant spacing, highest plant height (17.5 cm), leaf area (281.1 cm2), fresh weight (99.1 g plant-1) and dry weight (12.1 g plant-1) was revealed from wider spacing 30 cm x 30 cm followed by optimum spacing 25cm x 25cm. Meanwhile, closure spacing 15 cm x 15 cm showed maximum fresh yield (1710 g plant-1) and gross yield (15.5 t ha-1) due to higher plant density at final harvesting. Besides, lower chlorophyll content (0.43%) and the highest number of leaves (16.2) was found from 25 cm x 25 cm at final harvesting. So, optimum spacing 25 cm x 25 cm would be more suitable considering different points of view. Moreover, the treatment combinations 25 ppm GA3 with 25 cm x 25 cm exhibited highest benefit-cost ratio (2.04) than other treatments. Conclusions: It is concluded that the combinations 25 ppm GA3 application with 25cm x 25cm spacing would be optimum for better growth and yield of lettuce

Dryland in Indonesia has been dominated by acid soils, so that availability of phosphate (P) becomes the main obstacle in improving outcomes and only 10-30% of fertilizer P can be utilized by plants. One of the solution to meet the needs of phosphate is by utilization of mycorrhizal biofertilizer. These experiments were divided into several phases: 1) Looking for phases of mycorrhizal, 2) the laboratory analysis, 3) Testing phase on plants that were carried out by using polybags with sterile soil. The experiment was designed with a complete randomized block design (RAKL) by using a factor that consists of 6 treatments that are: 1) Without mycorrhizal inoculum (M0), 2) Mycorrhizal inoculum 5 g + 50 Spores (M5), 3) Mycorrhizal inoculum 10 g + 50 spores (M10), 4) Mycorrhizal inoculum 15 g + 50 spores (M15), 5) Mycorrhizal inoculum 20 g + 50 spores (M20), 6) Commercial mycorrhizal 10 g (Mk). All treatments were repeated four times so that the total 24 pot experiment. The experiment results show that mycorrhizal treatment given on the corn crop has very significant (P <0.01) to the number of leaf age of 35, 49, 63 days after, leaf wide have age 49 days after plant, fresh weight, oven-dry weight, absorb P, number of spores, mycorrhizal infection and significant effect (P <0.05) to plant height age of 35, 49, 63 day after plant, 63 days after plant, leaf wide, and P-available. Based on the results of this study will be suggested, in order to enhance the growth of corn plants can be used locally mikroiza a dose of 10 g + 50 spores.
