Abstract

The purpose of this research was to study the growth and production response of soybean, which was application use various watering frequencies and the application of water hyacinth compost. The design of this research using Randomized Complete Block Design factorial 3x6 with three replication. The first factor is the frequency of watering (P), that is P1 (once a day), P2 (once in two days), and P3 (once in three days). The second factor is the composition of water hyacinth compost (K), that is K1 (NPK Mutiara), K2 (100 % manure), K3 (25% manure + 75% water hyacinth compost), K4 (50% manure + 50% water hyacinth compost), K5 (75% manure + 25% water hyacinth compost), and K6 (100% water hyacinth compost). The result showed the frequency of watering and the composition of water hyacinth compost could increase the number and weight of pods, also the number and weight of seeds. The treatment with once-a-day watering frequency and 25% manure + 75% water hyacinth compost cause the best and efficient increase in the growth and production of soybean varieties Anjasmoro.

Abstract

The purpose of this research was to examine the effect of the concentration and the frequency of tofu wastewater and the interaction between concentration and the frequency of tofu wastewater on the growth and production of red chili (Capsicum annum L.) plants.  The method used in this research was a completely randomized design of a factorial pattern. The first factor is the concentration of tofu wastewater which is consists of 5 treatments, namely tofu wastewater (T0), tofu wastewater 25% (T1), tofu wastewater 50% (T2), tofu wastewater 75% (T3), and tofu wastewater 100% (T4). The second factor is frequency tofu wastewater (F) which consists of 3 levels, namely the frequency of tofu wastewater once time during the planting period on 14 days (F1), second times during the planting period which given when the plant is planted 21 and 42 dast (F2), and three times during the planting period, and which given when the plants were 14, 28, and 42 dast (F3)  with three replicates. The results showed that the type of tofu wastewater had a significant effect on the age of the first flowers, the total fresh fruit weight, and the total dry fruit weight. The frequency of tofu wastewater offering had a significant effect on the number of fruits planted. No interaction between the types concentrates on the frequency of tofu wastewater to vegetative and generative plant growth. The best result is the age at the first flower, the total weight of fresh fruit, and the dry weight of 100% tofu wastewater. The best number of fruit crops is the frequency of offering tofu wastewater as much as once watering.

Abstract

The aim of the study was to know the influence of the rice straw compost doses as fertilizer and the frequence microorganism local of banana weevil on the growth and yield of the strawberry. The experimental design of this research was Completely Randomize Design (CRD) factorial with three factors of rice straw compost doses (15, 20, 25 tons/ha) and three factors of frequence microorganism local of banana weevil (1 time, 3 times, and 5 times) with 3 replications. The parameter observed were bulk density of soil, porosity of soil, organic ingredients of soil, number of leaves, number of fruit, and weight of fruit. Data obtained was processed by analysis of variance and if there is an effect of yield treatment continued with Duncan multiple range test. The result showed that there are interaction between two treatment on bulk density and soil porosity. The compost doses and frequence microorganism local of banana weevil had significan effect on soil characteristic (bulk density, porosity, and organic ingredients of soil), improvement of best soil characteristic happen on compost doses 20 tons/ha and frequency microorganism local of banana weevil 2 times. Treatment of compost doses application 25 tons/ha will improve the parameters of number of leaves and number of fruit, while the best weight of fruit happen on compost doses 20 tons/ha with frequency microorganism local of banana weevil 1 time.
