Abstract

This study examines variations in agro-climatic conditions for rice farming in South Sumatra, Indonesia, over four different periods: 1981-1990, 1991-2000, 2001-2010 and 2011-2020. The Oldeman classification was used by the research on rainfall-based satellite observation datasets to analyze agroclimatic zonation within the region. It was established that the B1 zone suitable for rice cultivation remained the dominant agro-climatic zone throughout all these years (50.7% to 62.7% of the total area). However, C2 zone had a massive increase from 0.4 percent between 1981 and 1990 to a significant level of up to 18.6 percent by the year ending in 2011–2020. However, Musi Banyuasin had an increase followed by decreasing precipitation, but not Empat Lawang, where there was a decline. From these results, it can be concluded that there are changing precipitation patterns concomitant with shifts in agroclimatic situations across each locality.

Abstract

In an effort to solve the P availability issue in Inceptisols, fermentation is one method used to enhance the quality of liqiuid organic fertilizer (LOF) made from Moringa (Moringa oleifera). The type and concentration determine the effectiveness of LOF on nutrient uptake and plant yields. This study aims to evaluate the impact of LOF types, concentrations, and their interactions on P uptake and rice grain yield in Inceptisols. The research was conducted in a greenhouse using a completely random design (CRD) with two factors. The first factor is the type of LOF, consisting of two levels, i.e., fresh and fermented Moringa extract. The second factor is the LOF concentration, with four levels (i.e., 0, 20, 40, 60, and 80 ml/l) and three replications. Data analysis using ANOVA, DMRT, and correlation. The study revealed that the interaction between LOF types and concentrations affects P uptake. The highest P uptake shown by fermented Moringa with a concentration of 60 ml/l was 20.02 mg/plant and 40 ml/l was 18.73 mg/plants., or 1.5 times higher than the control. Grain yield was not affected by type, LOF concentration, or interaction. Fermented Moringa has good potential as LOF, while the effect on grain yield needs further research.

Abstract

Maize downy mildew disease in Java, caused by Peronosclerospora maydis, can cause yield losses of up to 100%. Disease management of downy mildew using synthetic fungicides has been reported to cause resistance to P. maydis. This study identified early fungicide resistance in P. maydis from several maize production centers in Java (Blitar, Kediri, Klaten, Cianjur, Garut, Jatinangor, Rancakalong, and Sukabumi) by examining fungicide sensitivity levels and detecting genetic variation. The study was conducted at the Laboratory of Biotechnology of Plant Protection, Department of Plant Pests and Diseases, Faculty of Agriculture, Universitas Padjadjaran from November 2018 to August 2019. The results showed that isolates from Blitar and Kediri (East Java) indicated resistance to metalaxyl and fenamidone. While in general, P. maydis isolates from West Java and Central Java still have sensitivity to metalaxyl, dimethomorph, fenamidone, and oxathiapiproline. Oxathiapiproline was the most effective fungicide in damaging P. maydis conidia in all locations. Based on the results of molecular identification, there is intraspecies genetic variation based on phylogenetic analysis.

Abstract

Breeding activities for winged bean plants (Psophocarpus tetragonolobus (L.) DC.) necessitate genetic diversity from local varieties. Identifying winged bean lines adds valuable initial information for shaping policies in plant breeding. Before proceeding with varietal development, it is crucial to establish the ideal type (ideotype) for superior winged bean varieties. The primary objective of this research is to ascertain the idiotype for superior winged bean varieties. The research was conducted in 2023 at Universitas Brawijaya, Indonesia, and involves the evaluation of five improved lines. The initial evaluation focuses on qualitative and quantitative characteristics of ideotype. The second evaluation concerns winged bean seeds' ideal morphological and physiological qualities. The third evaluation assesses winged bean pods' ideal physical and organoleptic preferences. The research outcomes have yielded the ideal morphological characteristics for winged bean varieties. This idiotype will be the foundation for the direction and target of winged bean plant breeding efforts, among the lines evaluated. NSM2 exhibits ideal flowering time and pod length characteristics, and lines PTL and PTL display ideal pod forms. MML and PBL lines have flavors aligned with market preferences regarding organoleptic qualities. These lines will be further improved through crossing to develop ideal varieties.

Abstract

The gambir plant can serve as a raw material for botanical insecticides. Plant-based insecticides are made in nanoemulsion form to overcome the insecticide particle size problem. This study aims to obtain a gambir waste form that has the potential to be used as a botanical insecticide using nanotechnology. The laboratory experiments include preliminary and follow-up tests. The preliminary test involves testing each extract (liquid, solid, and raw gambir waste) at three concentrations using a completely randomized design with four replications. The follow-up test uses the residue method on leaves to test insecticidal activity. Creating nanoemulsion from gambir waste involves mixing organic and liquid phases through spontaneous emulsification. The insecticidal effectiveness of this nanoemulsion is tested on Croccidolomia pavonana. The results show that solid and liquid gambir waste has the potential to be used as alternative insecticides, which can influence the mortality of C. pavonana with an LC50 concentration of 0.22 (solid waste) and 0. 29 (liquid waste), while LC95 is 2.44 (solid waste) and 2.52 (liquid waste). The research promotes utilizing natural resources and innovative technologies, advancing environmentally conscious pest control methods, and fostering sustainable agricultural systems.

Abstract

To investigate the impact of pre-treating on mineralized nitrogen production, we carried out an anaerobic incubation following five pre-treatment sets: (1) 5 g soil/50 ml water (Control), (2) 5 g soil/50 ml water/80℃/ 4 hours (Hot water), (3) 2.5 g soil/50 ml water/80℃/4 hours + 2.5 g soil (Mixed hot water), (4) 5 g soil/ 50 ml water/ultrasound 37 Hz/30 minutes (Ultrasound), and (5) 2.5 g soil/50 ml water/ultrasound 37 Hz/30 minutes + 2.5 g soil (Mixed ultrasound). Inorganic nitrogen was extracted before incubation (Initial In-N) and after 4 weeks of anaerobic incubation (Total Min-N and Net Min-N). The results reveal that Initial In-N ranged from 21.8 to 23.5 mg N/kg and was similar among four pre-treatment methods. Interestingly, Net Min-N was promoted by heating hot water; meanwhile, ultrasound pre-treatment did not enhance soil mineralization potential. This indicates that pre-treating soil with hot water could be a promising method to enhance soil nitrogen mineralization.

Abstract

Brazilian spinach is a highly nutritious leafy vegetable containing vitamins, minerals, and dietary fiber. This study assesses the impact of pruning intensities and non-nutrient ameliorants on Brazilian spinach growth in a floating cultivation system. The research follows a factorial randomized block design, with pruning intensity as the first factor and non-nutrient ameliorant as the second factor. Pruning intensity was categorized as light, moderate, and heavy, while the non-nutrient ameliorant included control, fine sand, rice-husk biochar, and fine sand + rice-husk biochar. The results show that moderate and heavy pruning effectively improved the response to NPK fertilization. Moderate pruning is proven to trigger the canopy area, especially starting 2 to 4 weeks after pruning. The Brazilian spinach canopy area demonstrated exponential growth and positively correlated with canopy diameter. The photosynthesis distribution in branch and shoot on moderate pruning was higher than heavy pruning, as indicated by dry weight. Moderate pruning produced a higher marketable yield than other pruning intensities. Regarding non-nutrient ameliorants, there are similarities in SPAD value, canopy area, index, dry weight, and yield. Therefore, moderate pruning is an effective practice to improve the growth and yield of Brazilian spinach, while the selected non-nutrient ameliorants have no impact.

Abstract

Rice length and shape are the important quality traits in rice that affect consumer acceptance and price. Rice length and shape can be improved through crosses followed by selection. Genetic parameters influence effective selection. The research objectives are to estimate genetic parameters for rice length and shape in the F2 population of Basmati Delta 9 x Koshihikari and Basmati Pakistan x Inpago Unsoed 1. F2 rice population from crosses of Basmati Delta 9 (extra-long, slender) x Koshihikari (short, round), Basmati Pakistan (extra-long, slender) x Inpago Unsoed 1 (medium, medium), and the parents are used for research material. The genotype is planted using an experimental design with no replication. Rice length and shape data were collected from each plant. The collected data is used to estimate the genetic parameters of rice length and shape. The results show that polygenes control rice length and shape. Transgressive segregation is obtained in the F2 population of Pakistan Basmati x Inpago Unsoed 1. The genetic diversity of rice length and shape is low, so reducing the selection intensity of these traits is suggested. The estimate of broad sense heritability and genetic gain of rice length and shape was high.

Abstract

Potential use of acid sulfate soils in agriculture is faced by low pH and the presence of a pyrite layer especially in dry conditions. In order for potential acid sulfate soils to support corn growth during the dry season, technological input is needed to improve soil fertility and overcome water availability by organic fertilizer palm oil mill effluent (POME) plus zeolite. The study used a Split Plot Design with two treatment factors. The treatment factors consisted of plots of water availability: C1 = 100%, C2 = 75%, C3 = 50%, C4 = 25%. POME subplot factor: L0 = No POME, L1 = Secondary Anaerobic POME  (zeolite 0%) dose of 1000 ml, L2 = POME Acidification Pool (zeolite 10%) dose of 1000 ml. Availability of water and the provision of POME plus zeolite affect pH, organic-C, total-N, P-Bray I, and soil CEC. In terms of plant growth, both treatments also influence canopy dry weight, seed weight, N content, P and proline leaf corn. Palm oil mill effluent acidification pool plus zeolite 10% dose of 1000 ml increases the adaptability of plants to water shortages and the fertility of potential acid sulfate soils, and the growth and production of corn.
