Abstract

This study aims to determine the effect of giving biochar and the type of fertilizer and its interaction in increasing the growth and yield of sweet corn plants. Randomized group design (RBD) Factorial pattern 2 factors (type of biochar and type of fertilizer) were used in this study. The results showed that the coconut shell biochar treatment provided the highest wet weight with 97.82 g which increased by 61.93% when compared to without biochar 60.41 g. The NPK-compost fertilizer treatment gave the highest value of weighted cob weight, which was 101.22 g which was significantly different and increased by 23.27% and 13.59% when compared with NPK fertilizer and compost treatments, respectively 89.11 g and 82.11 g.

Abstract

The study entitled "The Effect of Cow Manure Dose, Pearl NPK Against Long Beans (Vigan sinensis L.)". Aiming at knowing the growth, yield of long beans due to the dose of cow dung and NPK Mutiara. Conducted in February-April 2020. Using a Randomized Block Design (RBD) consisting of 2 factors: Cow Manure Dose, there are 3 levels: S0 (0 tons / ha), S1 (15 tons / ha) and S2 (30 tons) / ha ), NPK Mutiara fertilizer, there are 3 levels: M0 (0 kg / ha), M1 (150 kg / ha) and M2 (300 kg / ha). obtained 9 combinations, repeated 3 times. The results showed that there was no interaction between doses of cow dung and NPK Mutiara on the growth and yield of long beans, except for the fresh weight of brangkasang (P <0.05). Cow manure had a very significant effect (P <0.01) on the number of leaves, plant height, number of pods, pod weight, had no significant effect (P> 0.05) on pod length, fresh weight of stover, and oven dry weight of stover. NPK Mutiara fertilizer had a significant effect (P <0.05) on the number of leaves and pods, had no significant effect (P> 0.05) on other variables. The treatment dose of cow dung of 30 tonnes / ha (S2) gave the highest yield of 260.76 g on pod weight per plant, an increase of 32.35% compared to the lowest yield of 197.02 g at the treatment dose of 0 ton / ha of cow manure. (S0).

Abstract

The purpose of this study was to determine the effectiveness of the Beauveria bassiana fungus in controlling the pest and to determine the best concentration of Beauveria bassiana to control the pest. This research was carried out at the Pest and Disease Observation Laboratory (LPHP) at the Bali Province Food Crops and Horticulture Protection Center (BPTPH) from November 2020 to october 2021. This study used a completely randomized design (CRD). With a level of 5 concentrations, the concentration treatment was B1 = 2 ml Beauveria bassiana . liter-1 water, B2 = 4 ml Beauveria bassiana . liter-1 water, B3 = 6 ml Beauveria bassiana . liter-1 water, B4 = 8 ml Beauveria bassiana . liter-1 water, B5 = 10 ml Beauveria bassiana . liter-1 of water. The results showed that in the treatment with a concentration of 10 ml Beauveria bassiana . liter-1 Liter of water, the mortality percentage was 100%, which was not significantly different from the treatment with 8 ml of Beauveria bassiana . liter-1 of water with a mortality percentage of 97,5% and significantly different. with other treatments.

Abstract

Green beans have advantages over other food crops in terms of agronomy and economy, such as: (1) shorter-lived between (55-65 days) can be harvested, (2) more drought-resistant with relatively small water requirements for green bean growth, namely 700-900 mm / year. In rainfalls that are lower than that, it can still grow because it is deeply rooted, (3) it can be planted on less fertile land and fertilize the soil because it is symbiose with rhizobium and produces as much biomass (11-12 t/h), (4) easy cultivation methods are sufficiently minimal tillage and seeds are sown, (5) pest attacks are less diseased and (6) the selling price is high and stable. The purpose of the study was to determine the effect of planting distance and application of rabbit manure on the growth and yield of green bean plants (Vigna radiata L). The experimental design used was with a randomized design of the group and the analysis of the F test (analysis of variance) on the. This research was carried out in Subak Rapuan, Mas Village, Ubud District, Gianyar Regency with an altitude of 400 meters above sea level. The implementation of the study starts from March - June 2022. The highest fresh weight of seeds at the spacing treatment (J3) can be caused by wide planting distances and optimal fertilizer application. The wider planting distance provides space for access to sunlight, air temperature, and air humidity that can contribute to the growth and development of plants. The wider planting distance will reduce the competition higher so that with the J3 planting distance, it reduces the occurrence of nutrient competition so that the nutrients given through K3 fertilization will be used properly by plants. This shows that a dose of rabbit manure of 15 tons/ha-1 has the best effect on the growth of green beans so that it gives high yields compared to doses of 5 tons/ha-1 and 10 tons/ha-1. The fresh weight of seeds per plant is strongly supported by the presence of correlations in the number of pods (r = 0.889**) the length of the pods (r = 0.828*) and the number of seeds (r = 0.921**).

Abstract

This study aims to analyze the effect of giving concentrations of wood vinegar and arbuscular mycorrhizal biofertilizers on the growth and yield of soybean Edamame (Glycine max L. Merrill.). As well as to determine the interaction of giving a combination of wood vinegar and mycorrhizal biofertilizers on the growth and yield of Edamame soybean plants (Glycine max L. Merrill.). This research was conducted in the experimental garden of the Faculty of Agriculture, Warmadewa University, Jalan Terompong No.24, Sumerta Kelod, East Denpasar District, Denpasar City from May to August 2022. The research method used was a Randomized Block Design (RAK) with 2 factors arranged factorial . The first factor was the administration of wood vinegar (C), which consisted of 4 levels, namely C0 = Control (0% wood vinegar concentration), C1 = 2% wood vinegar concentration, C2 = 4% wood vinegar concentration, C3 = 6% wood vinegar concentration. the second factor used biological mycorrhiza (M) fertilizer which consisted of 5 treatment levels, namely M0 = Control (0 g.polybag-1), M1 = 5 g.plant-1, M2 = 10 g.plant-1, M3 = 15 g .plant-1, M4 = 20 g.plant-1 was repeated 3 times so that 60 polybags were needed. The results of statistical analysis showed that the dose of mycorrhizal biofertilizer had a significant effect (P <0.05) on the highest number of flowers per plant obtained in the M3 treatment (15 g.plant-1), namely 46.25 buds, an increase of 21.08% compared to mycorrhizal fertilizer treatment M0 (0 g.plant-1) namely 36.50 buds. The highest number of pods per plant was obtained in the M3 treatment (15 g.plant-1), namely 43.25 pods, an increase of 21.39% compared to the M0 mycorrhizal fertilizer treatment (0 g.plant-1), ie 34.00 pods. Keywords: edamame soybean, arbuscular mycorrhizal fertilizer, wood vinegar
