Abstract

The aim of the study was to evaluate the effect of the combination of doses of NPK fertilizer and coconut organic liquid fertilizer on the growth and production of tomato plants. The field experiment was carried out on October 7–December 30, 2021 at the Greenhouse Block C, and Ecology and Plant Production Laboratory, Faculty of Animal and Agricultural Sciences, Diponegoro University, Semarang Central Java. The study used a 4 x 3 factorial experiment on the basis of a completely randomized design (CRD) with 3 replications, so there were 36 experimental units. The first factor is the dose of NPK fertilizer with 4 treatment levels, namely NPK 375 kg/ha equivalent to 60 kg N/ha (according to the recommended dose equivalent to 7.5 g/plant = N1), NPK 281.25 kg/ha (75% recommended dose equivalent to 5.63 g/plant = N2), NPK 187.5 kg/ha (50% recommended dose equivalent to 3.75 g/plant = N3), and NPK 93.75 kg/ha (25% dose recommendation equivalent to 1.88 g/plant = N4). The second factor was the dose of coconut coir POC treatment with 3 levels, namely a dose of 300 ml of coconut fiber POC (K1), 500 ml of coconut fiber POC (K2) and 700 ml of coconut fiber POC (K3). Plant height, number of leaves, number of branches, stem diameter, flowering age, number of bunches per plant, number of fruits per bunch, number of fruits per plant, fruit diameter, fruit weight harvested, fruit weight per plant, and fruit quality were observed. The dataset obtained was analyzed for variance and further tested with Duncan's multiple distance test at the 5% level. The results showed that the dose of NPK fertilizer increased the number of branches, the number of bunches per plant, the number of fruits per bunch and the number of fruits per plant. Keywords: Coconut Organic Liquid Fertilizer, NPK, Tomat.Penelitian bertujuan untuk mengevaluasi pengaruh kombinasi antara dosis pupuk NPK dan POC sabut kelapa terhadap pertumbuhan dan produksi tanaman tomat.

Abstract

This study was aimed to determine the effect of humic acid, N, P, and K fertilizer and the interaction of the two treatments on the growth and production of sweet corn. The field experiment was carried out on August 02 – October 12, 2021 in Tembalang Sub-district, Semarang City and at the Ecology and Plant Production Laboratory, Faculty of Animal and Agricultural Sciences, Diponegoro University, Semarang (7o03’17” S dan 110o26’28” E). The factorial experiment with a 3 x 3 randomized block design with 3 replications was used in the study. The first factor was consisted of 20, 25, and 30 kg of humic acid/ha, respectively for M1, M2 and M3.The second factor was the dose of fertilizer N, P, and K which consisted of 100%, 75%; and 50% of the recommended dose, for P1, P2 and P3 respectively.The 100% of recommended dose was200 kg N/ha, 154 kg P2O5/ha, 125 kg K2O/ha. Parameters observed consisted of plant height, number of leaves, number of cobs, and weight of cobs. The data obtained were analyzed by using analysis of variance (ANOVA) and Duncan's test at 5% was used for further analysis. The results showed that the dose of humic acid had a significant effect on the parameters of plant height and number of leaves.  Keywords: dose, humic acid, sweet corn

Abstract

Utilization of acidic marginal land for the cultivation of peanuts results in uneven yield productivity. Acidic soil is soil with a low base saturation level which affects the absorption of plant nutrients from the soil. This study aims to examine the effect of biochar and inoculation of soil-fertilizing microbes, Rhizobium sp. and arbuscular mycorrhizal fungi (AMF), also its interaction on groundnut production on acid soils. This experiment used a 4 × 3 factorial experiment with a completely randomized design (CRD) which was repeated 3 times. The first factor was the type of biochar material which consists of no application or control (B0), corn cobs (B1), rice husks (B2), and coconut shells (B3). The second factor was the inoculation of soil-fertilizing microbes consisting of Rhizobium sp. (M1), arbuscular mycorrhizal fungi (AMF) (M2), and the combination of Rhizobium sp. + AMF (M3). The results showed that the application of biochar was significantly different to plant height, while the inoculation of soil-fertilizing microbes was significantly different to the number of leaves. Both showed no significant difference in the total weight of pods, seeds, soil pH, and the proportion of CMA colonization. Treatment of biochar from rice husk and double inoculation of Rhizobium sp. + CMA significantly obtains the highest yield in effective root nodule production.

Abstract

The research aimed to study the effect of manure enriched by rock phosphate and shoot pruning on the growth and yield of okra. The experiment used a 5 x 2 factorial based on randomized block design (RAK) with 3 replications, so that the obtained 30 units of treatment. The first factor was the type of  fertilization which consists of 5 levels, namely : P0 = TSP, P1 = poultry manure + TSP, P2 = cow manure + TSP, P3 = poultry manure + RP, P4 = cow manure + RP. The second factor was the shoot pruning which consists of 3 levels, namely : T0 = without shoot pruning and T1 = shoot pruning. Parameters measured number of branches, chlorophyll content,, flowering age, number of fruit, fruit weight, dry matter production and P uptake of stover on okra plants. Data were subjected to anova and followed by DMRT. The results showed that the type of fertilization and shoot pruning not significant the parameters of flowering age, chlorophyll content, dry matter production of stover and P uptake of stover on okra plants. The type of fertilization treatment and shoot pruning significant of the number of branches, number of fruit, and weight of okra fruit.

Abstract

Increased productivity of soybean (Glycine max L. Merrill) can be done through balanced and integrated fertilization. Rock phosphate and guano are natural sources of phosphor as an alternative to TSP fertilizer which has the advantage of not having a residual effect. The solubility of phosphor in natural phosphate is slow to be available. CMA inoculation can be done as an effort to increase the solubility of phosphor nutrients in natural phosphate. The aim of this study was to examine the response of soybean growth and yield due to CMA inoculation and natural phosphate fertilization, namely rock phosphate and guano. The research was conducted in January 2022 – April 2022 at the Greenhouse of the Faculty of Animal Husbandry and Agriculture, Diponegoro University, Semarang. The study design used a monofactor completely randomized design (CRD) with the treatments being natural phosphate fertilization and CMA inoculation with 6 treatment levels (T1:TSP; T2:BP; T3:Guano; T4:TSP+CMA; T5:BP+CMA; T6:Guano+CMA). The treatment was repeated 8 times, so that 48 experimental units were obtained. The treatment was repeated 8 times, so that 48 experimental units were obtained. The research variables included plant height, number of trifoliate leaves, flowering age, dry weight of straw, number of filled pods, and dry weight of seeds. The data were analyzed by analysis of variance, then if it had a significant effect, it was continued with Duncan's multiple distance test (DMRT) at 5% level. The results showed that CMA inoculation treatment and natural phosphate fertilization could increase plant height, number of leaves, number of filled pods, and dry weight of seeds.Keyword: guano, mycorrhizal,  phosphate, soybean
