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 aim of the study was to know the influence of the interaction of water hyacinth compost doses and Azolla microphylla green fertilizer doses on the growth and production of pakcoy. The research was conducted in the greenhouse and plant ecology and production laboratory of the Faculty of Animal Science and Agriculture, Diponegoro University, Semarang, Central Java. The study was conducted in January to March 2020. The experimental design of this research was Completely Randomize Design (CRD) 5 x 3 factorial pattern design with 3 replications. The first factor consists of 5 levels, namely without fertilizer, inorganic fertilizer (NPK), 50% recommendation of water hyacinth compost doses, 100% recommendation of water hyacinth compost doses, and 150% recommendation of water hyacinth compost doses. The second factor consists of 3 levels, namely without fertilizer, 50% recommendation of Azolla microphylla green fertilizer doses, and 100% recommendation of Azolla microphylla green fertilizer doses. The observed parameters were plant height, number of leaves, crown wet weight, and the production of the crown’s dry matter. Analyzing the data use variance analysis and Duncan’s multiple range test of 5% level. The results showed that there was an interaction between the treatment doses of water hyacinth compost and Azolla microphylla green fertilizer on plant height, number of leaves, crown wet weight, and the production of the crown’s dry matter. The treatment of 100% recommendation of water hyacinth compost doses (138 kg N/ha) and 100% recommendation of Azolla microphylla green fertilizer doses (138 kg N/ha) gave the best results than other treatments. The treatment of 100% recommendation of water hyacinth compost doses (138 kg N/ha) without the addition of Azolla microphylla green fertilizer as the same as the contribution of inorganic fertilizer that had done for once during cultivation to increasing the crown wet weight.

Abstract

Cucumber is a plant with many benefits and is liked by the community but has low productivity due to climate factors and farming techniques such as land management, fertilization, and irrigation. Increasing the productivity of cucumbers is carried out by utilizing the utilization of tea waste equipped with chicken manure to support plant growth. The aim of this research was to review the growth and production of cucumbers due to doses of compost tea and chicken manure. The research was carried out using a completely randomized design with a 4x4 factorial pattern with 3 replications. The first factor was the treatment of compost tea doses P0=control, P1=25 kg P2O5/ha, P2= 50 kg P2O5/ha, dan P3=75 kg P2O5/ha then the dose of chicken manure is A1= inorganic fertilizer, 150 kg P2O5/ha, A2= 75 kg P2O5/ha, A3=100 kg P2O5/ha, and A4=125 kg P2O5/ha The results showed that tea dregs compost and chicken manure have a significant effect on plant growth.The interaction between tea dregs compost and chicken manure gave a significant effect on the parameter of fruit weight with the best results at the treatment doses of 50 kg P2O5/ha /ha (P2) and 100 kg P2O5/ha /ha (A3).

Abstract

The study aimed to compare the growth and production of rice between three varieties, namely Ciherang, IR 64 (Membrano), and Inpari 23 (Aromatic) without or with soil amendment application (dolomite) on andosol soil from Karanganyar. The research design used was a split-plot with a Completely Randomized Design. The main plot is treatment without soil amendment (R1) and with soil amendment (dolomite) (R2). Subplots were Ciherang (V1), IR 64 (V2), and Inpari 23 (V3) varieties. Parameters observed were plant height, number of panicles, panicle emergence age, crown weight, root weight, root crown ratio, strawweight, grain weight, 1000 grain weight, and harvest index. The results showed that the variety factor had a significant effect (P0,05) on the age of panicle emergence and the number of panicles. The age of panicle emergence and the best number of panicles was found in the IR 64 variety. Variety factors had no significant effect on plant height, crown weight, root portion weight, root canopy ratio, strawweight, grain weight, 1000 grain weight, and harvest index. Soil amendment factors have no significant effect on growth, biomass production, and rice production. It can be concluded that the most superior rice growth and production is IR 64 variety followed by Ciherang and Inpari 23 varieties.
