Abstract

This study aims to study the interaction between NPK doses and types of ameliorant on the growth and yield of red chili plants and to obtain the optimum dose of NPK for each type of ameliorant that gives maximum yield of red chili. The experiment was conducted in the experimental garden of Padjadjaran University, Jatinangor District, Sumedang Regency from September to December 2021. The method used in this study was verification with an experimental approach using the Split Plot Design (SPD) consisting of two treatment factors. The first factor as the main plot was pearl NPK Fertilizer (N) which consisted of 3 treatment levels namely n1 (5 g L-1), n2 (7.5 g L-1), and n3 (10 g L-1). The second factor was the type of ameliorant (P) as a subplot consisting of 3 treatment levels, namely p0 (without ameliorant), p1 (amelioran 4 tons Ha-1), p2 (bioamelioran 4 tons Ha-1) so that there were 9 combinations of treatments each in repeat 3 times. There was an interaction between NPK dose and type of ameliorant on growth (plant height, number of leaves, stem diameter 3 and 4 WAP, root length 5 WAP and root decay ratio) and yield of chili plants (fruit weight per plant).

Abstract

Repeated processing of rice fields affects soil quality and degradation, which in turn impacts rice production. Therefore, a combination of NPK and humic acid is needed to prevent a decrease in NPK and to improve soil structure. this article studies about the effect of NPK fertilizer dosage and humic acid on the growth and yield of paddy rice. The experimental design used was a Split Plots Design with NPK as the main plot and Humic Acid as the subplot with each treatment having 4 dose levels and each repeated twice. Main plot of NPK dosage consists of 0 kg ha-1, 100 kg ha-1, 200 kg ha-1, and 300 kg ha-1. The subplots of humic acid doses consist of 0 g ha-1, 1500 g ha-1, 3000 g ha-1, and 4500 g ha-1. The results showed that there was an interaction between the dose of NPK fertilizer and humic acid on plant height, number of tillers, root drop ratio, number of productive tiller, number of grains per panicle, percentage of filled grain, weight of harvested dry grain per hill, weight of dry grain harvest per plot, weight of milled dry grain per hill and weight of milled dry grain per plot, except for the weight of 1000 grains. The dose of NPK fertilizer as much as 206.30 kg ha-1and the dose of humic acid as much as 2.928 kg ha-1 gave optimum results on the weight of dry milled grain which produced 6.15 kg per plot or equivalent to 10.250 tons ha-1.

Abstract

Background. The dormancy of Arabica coffee seeds is one of the main obstacles in the provision of quality seeds because the hard seed skin causes the germination process to take place slowly and is not uniform. Purpose. This study aims to obtain the best combination of types and concentrations of strong acids and planting media in increasing the viability, vigor, and growth of Arabica coffee seeds of the Sigararutang variety. Method. The research was carried out at the Greenhouse of the Faculty of Agriculture, Winaya Mukti University, using a Split-Plot Design with three replications. The main plot consists of two planting media, namely a mixture of soil: husk charcoal (2:1) and soil: manure (2:1), while the subplot is a combination of three types of strong acids (H₂SO₄, HNO₃, and HCl) at concentrations of 0%, 5%, 10%, 15%, and 20%. The parameters observed included germination age, germination power, growth rate, percentage of Soldier phase, percentage of Kepel phase, and seedlings height aged 91 days after planting. The data was analyzed using analysis of variance (ANOVA) and continued with the Duncan’s Multiple Range Test (DMRT) at a real level of 5%. Results. The results showed that there was a real interaction between the combination of strong acids and planting media on germination age and germination power. Treatment of HNO₃ 5% and HCl 10% on soil media: husk charcoal produces the fastest germination rate, while HNO₃ 5%, H₂SO₄ 20%, and HCl 10% on the same media result in the highest germination rate of 100%. The 5% HNO₃ treatment provides the best growth speed and seedlings height up to 8.11 cm at the age of 91 days after planting. Conclusion. Soil media: husk charcoal consistently yields better results than soil media: manure on most growth parameters. Thus, scarification using HNO₃ 5% combined with soil media: husk charcoal is recommended as the most effective pre-planting treatment to accelerate germination, increase viability and vigor, and produce more optimal early growth of Arabica coffee seeds.

Abstract

Spodoptera frugiperda is a newly emerging pest species attacking maize crops by damaging the plant whorl, thereby disrupting the growth point of the plant. The use of biological control agents, particularly the bioinsecticide Bacillus thuringiensis, represents one of the alternative strategies to manage S. frugiperda infestations. This study aimed to investigate the morphological characteristics and developmental changes of S. frugiperda following the application of the bioinsecticide B. thuringiensis. The experiment was conducted at the Basic Laboratory, Faculty of Agriculture, Winaya Mukti University, from August to September 2023. The experimental design employed a Completely Randomized Design (CRD) consisting of five treatments with six replications. The concentrations of the B. thuringiensis bioinsecticide were as follows: A = 0.00 g/L of water (control); B = 0.125 g/L of water; C = 0.25 g/L of water; D = 0.50 g/L of water; and E = 1.00 g/L of water. The results showed that the concentration of B. thuringiensis at 1.00 g/L significantly affected the morphology and development of S. frugiperda, as indicated by increased feed consumption loss, average larval weight, larval length, head capsule width, and larval mortality, which reached up to 90.00%. In addition, this concentration significantly influenced the percentage of pupae formation and the percentage of adult emergence.

Abstract

Cayenne pepper (Capsicum frustescens L.) cultivation faces several problems, including acidic pH and inadequate nutrient management. These problems can be addressed by using a mixture of various ameliorants and AB mix nutrient solutions. This study aimed to determine the effect of ameliorant mixture dosage and AB mix solution concentration on soil chemical properties, growth, and yield of cayenne pepper. The experiment used a randomized block design, consisting of two factors: nutrient solution concentration and ameliorant dosage. The factor of nutrient solution concentration consisted of four levels, i.e., 700, 1000, 1300, and 1600 ppm, while the factor of ameliorant dosage also consisted of four levels, i.e., 0, 2, 4, and 6 t ha-1. Observations were made on soil chemical properties, namely soil pH, organic carbon content, and cation exchange capacity (CEC). The agronomic characteristics observed were plant height, number of leaves, leaf area, chlorophyll content index, fruit length, number of fruits, and fruit weight per plant. The results showed no interaction between the concentration of AB mix solution and the ameliorant dosage on soil chemical properties, growth, and yield characteristics of cayenne pepper plants. The single effect of AB mix solution or ameliorant was observed on the number and weight of fruits per plant. The optimal dose for achieving the maximum harvested fruit weight was 6 t ha-1 of the ameliorant mixture (76.55 g pepper/plant), while the optimal AB mix concentration was 1600 ppm (65.02 g pepper/plant).
