Abstract

The low yield of soybeans is caused by drought, soft organic matter, and space for irregular plant growth. This study examines how plant spacing, and straw mulch dosage affect soybean yield. The research was conducted from August to December 2021 at the Field Laboratory of the Faculty of Agriculture, UHO. The research tools used in this study were tractors, hoes, ruler meters, ovens, analytical scales, and other supporting equipment. The materials consisted of soybean of the Anjasmoro variety, straw mulch, and other supporting materials. The study used a split-plot design arranged in a randomized block design. The main plot is the spacing (J) which consists of 2 levels, namely 20 cm x 20 cm (J1) and 20 cm x 30 cm (J2). Subplots were the dose of straw mulch (M) which consisted of three levels, namely without straw mulch (M0), 4 tons ha-1(M1), and 8 tons ha-1 (M2). The observed variables included the total number of pods per plant, weight of 100 seeds (g), seed weight per plant (g), harvest index (IP), and yield (tons). ANOVA analyzed data, and statistically different were tested by DMRT (α=0.05) using SAS 9.2. The interaction of plant spacing and straw mulch an increasing: the total number of pods, the weight of 100 grains, grain weight, harvest index, and yield. Plant spacing of 20 cm x 30 cm and the straw mulch of 8 t ha-1 (J2M2) obtained a product of 2.18 t ha-1 (an increase of 44.4%) compared to a spacing of 20 cm x 20 cm and without straw mulch (J1M0).

Abstract

The use of organic matter, which has a long-term impact, increases soil fertility because it contains residue. The research examines how rice straw mulch and organic fertilizer residue affect glutinous corn yield. This study was carried out at the Faculty of Agriculture Field Laboratory, Halu Oleo University, from May to August 2022. This Experiment used a randomized block design with a split plot design. The main plot, i.e. residue of rice straw mulch (M): without the residue of rice straw mulch (M0), the residue of rice straw mulch 4 t ha-1 (M1), and 8 t ha-1 (M2). Subplot, i.e. residue of plus organic fertilizer (P): without the residue of plus organic fertilizer (P0), a residue of plus organic fertilizer 2,5 t ha-1 (P1), 5 t ha-1 (P2), and 7,5 t ha-1 (P3). The length of the cob measured without husk, fresh weight of the cob with husk and without husk, dry weight of the cob without husk, number of seeds per cob, seed weight per cob, the weight of 100 seeds, and yield. After conducting an ANOVA analysis of the data, proceed with DMRT at a significant level of 95% if the analysis yields a significant effect (Fhit> Ftab). The research results showed that rice straw mulch plus organic fertilizer residue significantly affected yield components and yield. The residue of rice straw mulch 8 t ha-1 (M2) and deposition of plus organic fertilizer 7,5 t ha-1 (P3) produce the highest glutinous corn yield, i.e. 2,38 t ha-1 and 2,34 t ha-1 or increasing 92% and 75% compared without treatment. For efficiency of costs and realizing sustainable agriculture, it is necessary to utilize residues of organic material in the cultivation of food crops.

Abstract

This research aims to evaluate the effects of biomatriconditioning treatment of seeds and the age of seedlings at transplanting on the growth of paddy rice, simulating the System of Rice Intensification (SRI) method. The study employs a Split Plot design within a Randomized Complete Block Design (RCBD) with 3 replications. The primary focus is on seeds subjected to six biomatriconditioning treatments: untreated seeds (B1 and B2), treatment with red brick powder (B3 and B5), and treatment with rice husk charcoal powder (B4 and B6). The age of seedlings at transplanting is categorized into four levels: direct planting (H0), 7 days (H1), 14 days (H2), and 21 days (H3). Observed parameters encompass plant height, leaf count, tiller count, leaf area, and Relative Growth Rate (RGR). Analysis results indicate an optimal interaction at B6H1, displaying the tallest plant height, while the highest leaf count is achieved at B2H1. Maximum leaf area is attained at B4H3, and the highest tiller count is found in B5H2. The most effective treatment for RGR is transplanting after 21 days (H3), with the optimal biomatriconditioning treatment being B4. These findings suggest that the application of rice husk charcoal powder with Bacillus sp. PLK7 on 21-day-old seedlings holds the potential to significantly enhance paddy rice growth, aligning with the SRI method.
