Abstract

ABSTRACT Tamarind constitutes orthodox seed which is impermeable to water so that it is difficult to be penetrated by water in its imbibitions process. Consequently, the seeds have longer dormancy time so that special treatment is needed to accelerate its seed development. This research was done by soaking the seeds in the PGPR solution with the concentration and the soaking duration which are different from the purpose in order to accelerate the tamarind seed germination of the tamarind. The research used RAL (complete random sampling) consisted of soaking time (L) – L1: 2 hours, L2: 4 hours, L3: 6 hours, and PGPR concentration (P) which was Po; without PGPR concentration (control), P1: 10 ml/L of water, P2: 20 ml/L of water, and P3: 30 ml/L of water. The combination of treatment was 12 combinations, and each of them was repeated 3 times. The tamarind seeds were soaked according to the treatment, dried up, and germinated. The result of the research showed that germinating the seeds in 6 hours with PGPR concentration of 30 ml/L of water could accelerate the seeds until 4 days, 100% of sprouting power, 2.5% of vigor index, and 1% of germination rate.

Abstract

One of the organic waste processing technologies is Eco Enzyme. Eco enzyme is a complex solution of light to dark brown color, which has a fresh sour aroma. Organic waste, in the form of fruit peels, unused fruit flesh, and vegetable pieces, is collected in containers/barrels and then mixed with molasses/brown sugar and water with a certain dose. The recommended dose for the ratio of molasses: organic waste: water is 1:3:10. The fermentation results produce environmentally friendly enzymes and other beneficial elements for agriculture. This study aims to determine the nutrient content of P2O5, K2O, and the C/N ratio of eco enzymes derived from various organic materials. This study used a non-factorial, completely randomized design (CRD). This study used 6 treatment combinations consisting of: P1 = Musa paradisiaca L Boobs (1.5 kg) + Tithonia diversifolia Leaves (1.5 kg); P2 = Musa paradisiaca L weevil (1.5 kg) + Terminalia catappa leaves (1.5 kg); P3= Musa paradisiaca L Weevil (1.5 kg) + Spreading Leaf Shoots (1.5 kg); P4= Mimosa pudica Root (1.5 kg) + Tithonia diversifolia Leaf (1.5 kg); P5 = roots of Mimosa pudica daughter (1.5 kg) + Terminalia catappa leaves (1.5 kg); P6 = Roots of Mimosa pudica (1.5 kg) + Shoots of Spreading Leaves (1.5 kg). The results showed that using organic materials significantly affected the K2O content and the C/N ratio of the eco enzyme.

Abstract

This study aims to determine the production of soybeans with the application of mycorrhizal biological fertilizers and P fertilizers on the production of soybeans (Glycine max L. Meriil). This experiment was carried out at the Experimental Garden of the Faculty of Agriculture, Indonesian Methodist University, from August–October 2018. This study used a Randomized Block Design (RAK) consisting of Mycorrhiza (M) namely M0: 0 g/plant (control); M1: 5 g/plant; M2: 10 g/plant; M3: 15g/plant and Fertilizer (P), namely P0: 0 g/plant (control); P1:0.25 g/plant; P2: 0.5 g/plant; P3: 0.75 g/plant. All treatment combinations were 12 combinations and each treatment combination was repeated 3 times. Variables observed in this study include: flowering age (days); seed production per sample (g); seed production per plot (g); dry weight of 100 seeds (g). The experimental results showed that the interaction between mycorrhizal application and application of NPK fertilizer had a significant effect on seed production per sample, seed production per plot, dry weight of 100 seeds and not significantly different with flowering age. The highest seed production per sample was found in the M3P3 treatment of 26.32 g, the highest seed production per plot was found in the M3P2 treatment of 161.80 g and the highest dry weight of 100 seeds was found in the M3P3 treatment of 25.60 g. The mycorrhizal biofertilizer application treatment showed that the fastest flowering time was found in the M3 treatment, namely 36.58 days and 36.92 days in the P (P3) fertilizer treatment.

Abstract

This study aims to determine the effect of fruit pruning and application of Potassium on the growth and production of strawberry plants (Fragaria chiolensis). This study used a randomized block design (RBD) with 2 factors. The first factor was fruit pruning consisting of 4 levels: P0 = No pruning, P1 = 1 pruning, P2 = 2 pruning, P3 = 3 pruning. The second factor is Potassium fertilizer consisting of 4 levels: K0 = 0 g/plant, K1 = 2 g/plant, K2 = 4 g/plant, K3 = 6 g/plant. The observed variables were plant height (cm), flowering age (days), Fruit Weight (g), Fruit Volume (cm3), Sugar Content (%), Plant Wet Weight (g), and Plant Dry Weight (g). The results showed that pruning three fruits/plant increased plant height, fruit weight, fruit volume, sugar content, fresh weight and dry weight. Applying potassium fertilizer up to a dose of 6 g/plant can increase plant height, flowering time, fruit weight, fruit volume, sugar content, and wet and dry weight. Meanwhile, the interaction between fruit pruning and potassium application had no significant effect on all observed parameters.

Abstract

The research aims to determine the Effect of Providing Compost and NPK fertilizer 16:16:16 on the Growth and Production of Cucumber Plants (Cucumiss sativus). This research used a factorial Randomized Group Design (RAK) using 2 treatment factors. The first factor is dose treatment, which consists of 3 levels, namely K1: No compost, K2: Compost dose 10 t/ha or 1 kg/plot, and K3: Compost dose 20 t/ha or 2 kg/plot. The second factor is the dose of NPK 16:16:16 fertilizer, namely:N1: NPK fertilizer dose 250 kg/ha or equivalent to 25g/plot, N2: NPK fertilizer dose 350 kg/ha or equivalent to 35g/plot, N3: NPK fertilizer dose 450 kg/ha or equivalent to 45g/plot. The results showed that the dose of compost had a significant effect on fruit weight; a dose of 2kg/lot of chicken coop compost produced the heaviest fruit weight but had no significant effect on plant height, number of leaves, flowering time, fruit length, fruit diameter and number of fruit on cucumber plants. The dose of NPK 16:16:16 fertilizer had no significant effect on all observed parameters. The interaction between the chicken coop compost dose and the NPK 16:16:16 fertilizer had no significant effect on all observed parameters.
