Abstract

Shallots are one of the horticultural commodities that are highly expected to be cultivated intensively. The need for shallots nationally increases from year to year. These needs cannot be increased by increasing national production. One thing that can be done to make shallots available is to use good varieties and provide growth regulators with auxin using botanical seeds (True Shallot Seed) as a seed source. This study aims to determine the effect of the interaction between varieties with auxin concentration on the growth and production of shallots. This research was carried out in the Exfam Land, Faculty of Agriculture, Hasanuddin University, Makassar, South Sulawesi Province, from August to November 2021. This study used a Split plot design which consisted of two factors, the first factor as the main factor being different plant varieties, namely Lokananta, Maserati, and Sanren. While the sub-plot is the concentration of Auxin consisted of 4 levels, namely 0 mg L-1,100 mg L-1, 200 mg L-1, and 300 mg L-1 . The experimental results showed that the red onion variety using the variety with a concentration of 200 mg L-1 gave the best results on the fresh weight of shallots (123.80 g), the dry weight of shallots (93.77 g), the tuber weight of (86.63 g/plot), tuberproduction (4.51 kg/plot), and productivity (19.50  ton ha-1). The treatment of shallot varieties using the Sanren variety gave the best results on the parameters of the number of bulbs (1.89 bulbs). The application of auxin at a concentration of 300 mg L-1 gave the best results on the tuber diameter parameter of 28.42 mm.

Abstract

This study aimed to evaluate the potential of combined indigenous antagonistic bacteria against Fusarium oxysporum f.sp. cepae by in vitro. These bacteria were originated from coffee plant litter in UB Forest and already known their ability as a single biocontrol against F. oxysporum. The research was conducted at the Plant Disease Laboratory, Department of Plant Pests and Diseases, Brawijaya University. The methods consisted of isolate preparation, pathogenicity test and in vitro antagonistic test using a modified multiple culture method. The study was conducted with eight treatments and four replications.  Based on this study, there were four best treatments in inhibiting the mycelia growth of F. oxysporum more than 50% compared to the control. The highest inhibitory was Bacillus mycoides and Alcaligenes faecalis which were able to inhibit F. oxysporum up to 67,46%. This study proves the potential of a new combination of indigenous antagonistic bacteria to inhibit fusarium wilt disease.

Abstract

Climate change, which exposes farmers to low productivity, crop failure and worsens food insecurity in developing nations has become a core challenge in Nigeria. These extremes have increased the vulnerability of several arable crop farmers due to inadequate mitigation strategies and restricted access to capital. This study analyzed climate change adaptation among cassava farmers in Okigwe agricultural zone of Imo State, Nigeria.  Perception of cassava farmers towards climate change, their adaptation strategies and challenges to climate change adaptation and determinant of farmers’ adaptation to climate change were the main objectives. A multi-stage random sampling procedure was used in selecting one hundred and twenty respondents for the study. Data were collected using structured questionnaire and analyzed with percentages, mean and Chi square. Results showed that the mean age of the respondents was 47 years while 78.30% of them had formal education.  The main adaptation strategies included planting on mounds (20%), diversification to non-farm activities (15%) and planting of improved varieties (14%). Cassava farmers in the study area perceived climate change as increase in heat waves (x̅=2.26), rainfall (x̅=2.76) and drought (x̅=2.35). The major challenges to adaptation were unsatisfactory weather reports (89.5%), lack of funds (82.4%) and inadequate extension contact (81.2%). Extension contacts and access to credit were the most significant determinants of utilization of climate change adaptation strategies. The study concludes that respondents are aware of climate change with diverse adaptation strategies and recommends that government and agricultural development agencies should integrate the determinant of climate change adaptation and mitigation into policies and programs relating to climate change resilience.  It also recommends that the availability of climate change information in real time, mobilization of more extension workers and provision of funds to improve the capacity of cassava farmers for climate change resilience should be prioritized

Abstract

Nutritional status is the end result of the balance between the food that enters the body (nutrient input) and the body's need (nutrient output) for those nutrients. In other words, the state of the body as a result of food consumption and the use of nutrients. Nutrient requirements are determined by many factors, including: basal metabolic rate, growth rate, physical activity, and relative factors, namely: ingestion, differences in absorption, utilization, and differences in excretion and destruction of nutrients in the body. A sample of 82 children aged between 2.5 and 5.0 years and 114 households representing adulthood was observed in two villages with Maudu' rituals, and 99 and 134 households in two villages without Maudu' rituals. The research was conducted in Cikoang Village, Takalar District. The results of this study indicate that the nutritional status of children under five in Cikoang Village is not good and needs attention from related parties in helping to improve child nutrition in Cikoang Village.

Abstract

Extracting total RNA from plant tissue using the conventional isolation method is time-consuming, requires expensive reagents and produces low-quality RNA. Over time, researchers have used many commercial RNA extraction kits on silica column-based to obtain high-quality RNA so that the isolated RNA can further use for sequencing and quantitative PCR analysis. This study aimed to identify the efficient apple leaf extraction method with high concentration and good quality RNA extraction. In this study, we applied four isolation kits to extract RNA from apple leaves, such as NucleoSpin® RNA Plant Kit (Macherey-Nagel), Quick-RNA™ Miniprep Kit (Zymo Research), PureLink® RNA Mini Kit (Ambion), and RibospinTM Plant Kit (GeneAll). The results showed that apple leaves RNA isolation successfully using the RibospinTM Plant Kit (Geneall) reagent with a concentration of 59.9±12.3 ng/µl in good RNA integrity. So, these isolated RNA can be used for further analysis.

Abstract

Rice is an important commodity for main staple in Indonesia. The need for rice will increase so that efforts are needed to increase its production. The use of superior varieties is an option to optimize land use whose area is increasingly limited due to population growth. The development of varieties is not only considered in terms of food production but is developed as an ingredient to meet nutritional needs. One of the local rice varieties that have the potential to be developed is Toraja local red rice (Pare Lea). Development of local rice character improvement through mutation breeding. Selection of superior genetypes is not only based on high production characters, but also the necessary information related to the relationship between characters that support production. This study aims to obtain information about the relationship between the components of growth and production of Toraja local red rice. This experiment used 9 mutant lines at fourth generation (M4)  as treatment and 1 non-mutant line as control. Agronomic characters that can support rice production were such as plant height, panicle length and grain yield per plant
