Abstract

This study aims to determine the effect of biochar dosage and compost fertilizer and its interaction on the growth and yield of corn crops. This experiment used a randomized block design (RBD) with a factorial pattern consisting of 2 factors. The first factor was the dose of biochar (B) consisting of 4 levels, namely: 0 ton ha-1 (B0), 5 ton ha-1 (B1), 10 ton ha-1 (B2), 15 ton ha-1 (B3). The second factor is the dosage of compost fertilizer (K) consisting of 2 levels: 0 ton ha-1 (K0), and 20 ton ha-1 (K1). The results showed that the interaction between the treatment of biochar dose and compost fertilizer had no significant effect on all observed variables. Biochar and compost treatment have significant effect to most observed variables, except on leaf area and harvest index have no significant effect. Treatment of biochar with a dose of 10 ton ha-1 gave the highest dry kiln seedlings weight of 7.83 tons increased by 35.60% compared to the lowest dose without biochar of 5.77 tons. Treatment of compost doses of 20 ton ha-1 gave the highest dry seed oven per hectare weight of 7.42 tons increased by 16.60% when compared with the lowest yield on treatment without compost dose as much as 6.37 tons.

Abstract

This study aims to determine the effect of NPK combined with biochar from various agricultural wastes in increasing the growth and yield of red chili plants. The research method used was a Randomized Complete Block Design (RCBD) with a factorial pattern, involving two factors and three replications. The first factor is the NPK fertilizer dosage, comprising four levels: 0, 300, 600, and 900 kg ha-1. The second factor is the biochar treatment, consisting of four types: biochar from mangosteen skin, biochar from rambutan, biochar from coffee skin, and biochar from rice husk. The application of NPK fertilizer has a significant to very significant effect on all observed variables, except for intangible effects on variables such as stem diameter, root fresh weight, plant fresh weight, and root dry weight. The biochar treatment has no significant effect on all observed variables, except for fruit weight and fruit count, which show a significant effect. The interaction between NPK fertilizer and biochar has no significant effect on all observed variables, except for plant height, number of leaves, number of fruits, and fruit weight, which exhibit a significant to very significant effect. The highest fruit weight of 205.70 g was obtained from the interaction between a dosage of 900 kg ha-1 with biochar from coffee skin, showing an increase of 114.72% compared to the lowest treatment fruit weight obtained from the interaction between no NPK dosage and biochar from rambutan, which was 95.80 g.

Abstract

This research aims to determine the effect of applying liquid organic fertilizer and NPK fertilizer and their interactions, on the growth and yield of cayenne pepper plants (Capsicum frutescens L.) which was carried out in Kupang City, Oebobo District, East Nusa Tenggara starting in June 2023 until September 2023. This research method uses a randomized block design (RBD) arranged factorially with 2 factors. The first factor tried was liquid organic fertilizer (P) which consisted of 4 concentration levels, namely: P0 (0 cc L-1 water), P1 (25 cc L-1 water), P2 (50 cc L-1 water), and P3 (75 cc L-1 water). Meanwhile, the second factor that was tried was NPK (N) fertilizer which consisted of 4 dose levels, namely: N0 (0 kg ha-1), N1 (150 kg ha-1), N2 (300 kg ha-1) and N3 (450 kg ha-1). There were 16 combination treatments, each repeated 3 times so that 48 cayenne pepper plants were needed. This research results showed that the interaction between liquid organic fertilizer and NPK fertilizer had a real influence on almost all the variables observed except stem diameter and number of flowers formed. The highest average fruit weight per plant was obtained at a liquid organic fertilizer concentration of 25 cc L-1 water (P1), namely 110.17 g, or an increase of 12.32% when compared to treatment without liquid organic fertilizer, namely 98.08 g. Meanwhile, with NPK fertilizer treatment, the highest average fruit weight per plant was obtained at a dose of 150 kg ha-1, namely 115.25 g, or an increase of 26.41% when compared to the control (N0), which was only 91.17 g. The interaction of the POC concentration treatment of 75 cc L-1 water with an NPK fertilizer dose of 150 kg ha-1 (P3N1) gave the highest fruit weight gain of 133.00 g (P3N1) although supporting variables such as the growth of cayenne pepper plants gave different results. different in the treatment of liquid organic fertilizer concentration and NPK fertilizer dosage.

Abstract

This study aims to determine the interaction of Bokasi Fertilizer and Atonic Growth Regulators on the growth of tomato plants. This research was conducted in the greenhouse of the Faculty of Agriculture, Warmadewa University, JI. Ompong 24 Tanjung Bungkak, Denpasar with a height of 25 m above sea level. This research starts from August - October 2023. This experiment uses a factorial pattern Group Randomized Design (RAK) with two factors, namely: Factor I is atonic ZPT with 4 levels of concentration, namely: A0 = 0 cc 1-1, A1 = 1 cc 1-1, A2 = 2 cc 1-1, A3 = 3 cc 1-1, Factor II is bokashi fertilizer consisting of 4 concentrations, namely: B0= 0 tons / ha, B1 = 10 tons / ha, B2 = 20 tons / ha, B3 = 30 tons / ha, Thus there are 16 combination treatments, each of which is repeated 3x so that there are 48 experimental polybags. The treatment of atonic growth regulators 1 cc 1-1 tends to give the highest dry weight yield of 148.68 grams, which is not real from other treatments. The treatment of 30 tons / ha of bokasi fertilizer tends to produce the highest dry weight of 149.44 grams which is not real from other treatments. Bokasi fertilizer has a real effect (P<0.05) on the fruit diameter and no real effect (P>0.05) on other variables. The treatment of bokasi fertilizer of 30 tons / ha produces the highest fruit diameter of 3.49 cm which is not real with the treatment of fertilizer 0 tons / ha and 20 tons / ha with fruit diameters of 3.31 cm and 3.40 cm respectively, but differs markedly from the application of bokasi fertilizer of 10 tons / ha with a fruit diameter of 3.10 cm. Bocation fertilizer tends to show no real influence on the growth and yield of tomato plants which is likely due to goat manure bokashi fertilizer has not been absorbed by tomato plants optimally.
