Jurnal Lahan Suboptimal: Journal of Suboptimal Lands (JLSO) (p-ISSN 2252-6188; e-ISSN 2302-3015) publishes original research papers, literature reviews, and short communications that cover on topics relevant to suboptimal lands: freshwater swamps, tidal lowlands, peatlands, dry and dry acid lands, shaded ecosystem, ex-mined lands, saline and marine coastal wetland ecosystems. The Journal serves as a multi-disciplinary forum covering key issues in Suboptimal Lands science and technology, management, policy and ecological economics. The journal is published by Pusat Unggulan Riset Pengembangan Lahan Suboptimal (PUR-PLSO), Universitas Sriwijaya. The journal was first published on April of 2012 with twice per year in frequency on April and October.

Abstract

The yield was a complex quantitative character. It was due to many other characters being related to yield. This study aimed to determine the correlation between agronomic characters in maize and the characters that affect the yield of hybrid maize. This experiment was conducted at the Bajeng IP2TP, Indonesian Cereal Research Institute, Gowa, South Sulawesi from March to June 2022. The treatments consisted of ten hybrid maize genotypes. The treatments were arranged in a Randomized Complete Block Design (RCBD) with three replications. The variables observed were the agronomic component and yield component. Pearson's correlation was used to determine the relationship between characters, and the characters that affected the grain yield were determined by path analysis. The results showed the characters leaf length, leaf width, harvested plant number, harvested ear number, harvested ear weight, shelling percentage, ear length, ear diameter, kernel number per row and 1000 grains weight have a significant correlation to yield. Characters that affected to maize yields were harvested ear weight, shelling percentage and grain moisture.

Abstract

The aimed of this study was to determine the effect of chicken manure application on red chili plants using conventional and floating cultivation techniques. The research was carried out on the experimental farm for conventional cultivation techniques and in research pond for floating cultivation located in the Faculty of Agriculture, Sriwijaya University, Indralaya Campus, Ogan Ilir, South Sumatra with an altitude of 10 m above sea level from July to November 2022. The experiment used a randomized block design with one factor, namely chicken manure (0, 10, 20 and 30 tons/ha) with three replications. While the floating experiment used 200 cm x 100 cm of bamboo rafts. Parameters observed included plant height, number of leaves, crown diameter, fruit length, fruit diameter, fruit weight per fruit, and total fruit weight per plant. Data were analyzed using Analysis of Variance (ANOVA) at the 5% level. The results showed that increasing the dose of chicken manure up to 30 tons/ha in both cultivation techniques increased plant height and number of leaves. Likewise for the number and weight of fruit, obtained at the same dose in conventional techniques, namely 30 tons/ha. However, fruit length and diameter parameters were higher in floating cultivation at all doses of chicken manure treatments. Therefore, it was concluded that the use of chicken manure could increase the growth of chili plants in both cultivation techniques, although the size of the polybags used could not support the growth and yields optimally.
