Abstract

Rice is a food crop commodity that serves as the staple food for the Indonesian population. This study examines the adaptation of various rice varieties with the addition of ameliorants on growth and yield in rainfed paddy fields. The research was conducted in Lahat District, Lahat Regency, from January to May 2024, utilizing a split-plot design with 12 treatment combinations, each replicated three times. The main plot treatments consisted of ameliorants, while the subplot treatments involved different rice varieties. The observed parameters included plant height (cm), number of tillers, number of productive tillers, panicle length (cm), flowering age (days after sowing), harvest age (days after sowing), total grains per panicle (grams), percentage of empty grains (%), 1000-grain weight (grams), and productivity (ton/ha). The results indicated that applying ameliorants, such as lime and solid organic fertilizer, yielded the most favorable outcomes for rice plant growth. Tabular analysis revealed that the Situ Bagendit variety exhibited the highest productivity compared to other varieties. Furthermore, the combination of ameliorants, specifically lime and organic fertilizer, along with the Situ Bagendit variety, achieved the highest paddy productivity at 5.13 tons per hectare.

Abstract

Rice (Oryza sativa L.) is a staple food crop that is being promoted as part of efforts to enhance national food security. The utilization of dry land in Indonesia is one mechanism that supports this food security initiative. Seed priming treatments have been shown to improve plant tolerance to drought stress conditions. This adaptation study aims to investigate the differences in seed viability among several rice varieties subjected to different concentrations of ZnO nanopriming, as well as the performance of selected seeds grown under drought stress conditions during the vegetative phase of the plants. The first phase of the research involved seed screening and variety selection, accompanied by seed priming treatments. The experimental design employed was a Factorial Randomized Block Design, with the first factor being ZnO concentrations of 0 ppm, 10 ppm, 15 ppm, and 20 ppm. The second factor involved the selection of four rice varieties: Ciherang, Inpari 32 HDB, Mekongga, and the expired Ciherang. The second phase of the research built upon the first phase, utilizing the best rice seeds identified from the screening results along with the most effective priming treatment. These seeds were subjected to drought stress treatments (without watering), which included 0 HTS, 5 HTS, 7 HTS, and 14 HTS. The results indicated that the seed priming treatment with ZnO nanoparticles (NPs) significantly increased the germination percentage of rice seeds across all varieties, with the optimal treatment combinations being 30 ppm for the Ciherang variety and 100 ppm for the Mekongga variety. Under drought stress conditions, the Ciherang variety at 30 ppm exhibited the best adaptation up to 14 HTS. Overall, the application of nano-priming with ZnO NPs enhanced seed germination and promoted plant growth.

Abstract

Acidic drylands are classified as suboptimal lands due to their low soil fertility, characterized by poor nutrient content, low organic matter, poor soil structure, and inadequate drainage. Glutinous corn is one of the corn varieties susceptible to acidic dryland conditions, although some varieties exhibit greater tolerance. This study aims to evaluate the effects of various types of organic fertilizers on acidic drylands and on the growth and yield of glutinous corn (Zea mays var. Ceratina Kulesh). The study was conducted at Jl. Sukarela, Km 7, Sukarame District, Palembang City, using a field experiment with a non-factorial Randomized Block Design (RBD) consisting of four treatments, each replicated six times. The treatments included: no organic fertiliser, chicken manure fertiliser (30 tons/ha), liquid organic fertiliser from vegetable waste (20 mL/L), and a combination of chicken manure fertiliser with vegetable waste POC. The parameters observed were plant height, number of leaves, cob length, cob weight per plant, cob weight per plot, dry stalk weight per plot, and weight of 100 seeds. The results showed an increase in soil fertility, as indicated by improved soil structure and a rise in soil pH from 5.3 to 6.5. The liquid organic fertiliser from vegetable waste, at a dose of 20 ml/L, was the most effective treatment, with an average cob weight per plant of 240.3 g (equivalent to 1.28 tons/ha).

Abstract

This study aimed to determine the diversity of arthropods on peanut plants (Arachis hypogaea L.) grown on land treated with organic fertilizer. The research was conducted from July to December 2024 at Jalan Sukarela KM 7, Palembang City. Data collection for arthropods in the plant canopy was performed through direct observation, involving the counting and identification of arthropods visible on the surfaces of leaves and stems, without the use of nets. For soil surface observations, the pitfall trap method was employed. The observation parameters included the identification of arthropod types and the calculation of the diversity index at both the canopy and soil surface levels of the plants. Arthropods found in the peanut plant canopy belonged to 5 orders and 10 families, while those on the soil surface comprised 7 orders and 9 families. The diversity index in the plant canopy was 2.12, categorised as medium, whereas on the soil surface, it was 1.57, classified as low.

Abstract

Corn is a strategic food commodity with increasing demand, necessitating enhanced production through optimized fertilization, especially in marginal lands such as tidal areas. This study aims to evaluate the effect of foliar fertilizer application on three corn genotypes and its impact on nitrogen fertilizer use efficiency in tidal lands. A split-plot design with three factors was employed: the first factor was corn genotype; the second factor was urea fertilizer dose (0 kg, 255 kg, and 310 kg per hectare); and the third factor was foliar fertilizer treatment, which included no spraying (control), spraying on the 30th day, the 45th day, both the 30th and 45th days, the 60th day, the 75th day, and both the 60th and 75th days. Each treatment was replicated three times. The results indicated that applying 300 kg of urea fertilizer per hectare, combined with foliar fertilizer, positively influenced the growth of the G3 corn genotype and resulted in a high yield in tidal lands. This treatment produced 7.44 tons of corn per hectare, a significant increase compared to other treatments, making it an efficient strategy for enhancing corn productivity in tidal areas. It is recommended that farmers in tidal regions use a combination of 300 kg urea per hectare and foliar fertilizer applications to optimize corn yields.

Abstract

Dry land has significant potential for cultivating hybrid corn. However, its limitations include water scarcity, poor soil physical properties, and limited availability of NPK nutrients. To improve dryland conditions, organic fertilizers, inorganic fertilizers, and organic fertilizers enriched with phosphate-solubilizing bacteria can be applied. The use of organic fertilizers—such as chicken manure and empty oil palm bunches (tankos)—as well as organic fertilizers enriched with phosphate-solubilizing bacteria, can enhance soil quality by improving its physical structure (making the soil looser and more fertile) and chemically increasing nutrient availability, thereby supporting better growth and yield of hybrid corn plants. This study aimed to evaluate the effectiveness of various fertilizer types on the growth and productivity of hybrid corn cultivated on dry land. The field experiment was arranged in a randomized complete block design (RCBD) with four treatments, each replicated six times: recommended chemical fertilizers (A), chicken manure fertilizer (B), organic fertilizer enriched with phosphate-solubilizing bacteria (C), and empty oil palm bunches (tankos) fertilizer (D). The highest yield was achieved using the recommended chemical fertilizer, producing 3.42 kg per plot (13.68 tons per hectare). The second highest yield was obtained with organic fertilizer enriched with phosphate-solubilizing bacteria, yielding 2.98 kg per plot (11.92 tons per hectare). The third-highest yield came from chicken manure fertilizer, producing 2.67 kg per plot (10.68 tons per hectare), followed by tankos fertilizer at 2.2 kg per plot (8.8 tons per hectare). The novel finding of this study is that organic fertilizer enriched with phosphate-solubilizing bacteria, without the addition of inorganic fertilizers, can achieve yields comparable to those obtained with recommended chemical fertilizers. While inorganic fertilizers are effective in increasing hybrid corn yields in the short term, their long-term use may negatively impact the environment and soil fertility. Therefore, organic fertilizer enriched with Azospirillum bacteria presents a more environmentally friendly and sustainable alternative.
