International Journal of Agriculture System (Int. J. Agr. Syst.- IJAS) is published by Hasanuddin University (UNHAS) twice a year in June and December. This journal is an academic, citation indexed, and blind peer-reviewed journal. It covers original research articles, short notes and communications, reviews (including book), concepts, commentaries, and letters on a diverse topic related to agricultural systems including forestry, fishery/marine, and animal sciences. The aims of this journal are to provide a venue for academicians, researchers, and practitioners to share/discuss theories, views, research results, on issues related to the science, engineering and technology, and humanities in agriculture development, management, and issues in agricultural systems, particularly in the tropics. However, any other articles related to non-tropical agricultural systems are also welcome.

Abstract

Soil profiles are generally heterogeneous and consist of various horizontal layers due to geological processes, the formation of crusts, or other artificial or man-made activities. To quantify infiltration into these heterogeneous soil profiles, the Modified Green-Ampt Model (MGAM) is a physically-based hydrologic model that can efficiently perform under both steady and unsteady rainfall events. Based on the secondary data, this study sought to determine the effect of changing soil layers (soil textures) on infiltration rates and cumulative infiltrations in in both laboratory and field settings. Different scenarios were analyzed by rearranging soil layers and evaluating their impacts on corresponding infiltration rates and cumulative infiltrations. Simulations were run with HYDROL-INF software environment using MGAM. Three scenarios were considered for a laboratory experiment with two different types of soil texture coupled with five different soil profiles. Similarly, four scenarios were considered for the field experiments with five different types of soil texture couple with eight different soil profiles. The simulated infiltration rates and cumulative infiltrations were found to vary with soil layer change scenarios. The simulated cumulative infiltrations, ponding times, infiltrating rates at ponding, and total depth of wetting front at ponding of a five-layered laboratory soil column were identical for the three scenarios. Simulated cumulative infiltrations were 33.16, 23.65, 21.29, and 42.77 cm, respectively, for scenarios (combinations) 1, 2, 3, and 4 in the eight-layered soil profile in the field scenarios. Infiltration rates among scenarios at ponding were identical (0.46 to 0.53 cm/h) with field scenario data.

Abstract

The Cattle Livestock Business Insurance Program aims to provide protection for cattle from the risk of death and loss of cattle. This study aimed to determine the level of satisfaction of farmers with cattle business insurance in Gowa Regency, South Sulawesi Province. This research was conducted in May 2022. The population is all cattle farmers who follow cattle business insurance in Gowa Regency. The sample is farmers who follow cattle business insurance in Pattalassang sub-district, Gowa Regency amounted 45 people. The research method used was the interview method and FGD (Focus Group of Discussion). The type of data used is qualitative data, namely data in the form of words and quantitative data in the form of numbers or numbers Analysis of the data used with the CSI model. The results show that farmers feel much helped by the existence of AUTS which can minimize the risk of failure in the cattle business, namely the death of the cattle they receive, so that at least it can relieve and not be confused in looking for business capital again. It can also motivate and eliminate the worries of farmers to increase the scale of their business. Farmer satisfaction with AUTS is in the excellent category, which means very satisfied and in accordance with the expectations of farmers, both in terms of service characteristics, personal relationships, service arrangements and customer strength.

Abstract

The content of polysaccharides, polyphenols, proteins, and RNA compounds is the main problem often found in Plants DNA isolation, which inhibit the process of DNA isolation. Comparing the methods of plant DNA isolation is necessary for obtaining the DNA with good quality, purity, high concentration and efficiency time and cost. This study aimed to determine the best DNA isolation method that derived from leaves of a potential anti-cancer Rodent Tuber (Typhonium flagelliforme) plant by comparing the conventional DNA isolation method (cetyl trimethyl ammonium bromide/CTAB) and 2 commercial kits (Promega Wizard™ Genomic DNA Purification Kits, and Geneaid Genomic Mini Kit). The results showed that the CTAB method yielded a higher amount of DNA (>100 ng/µL) at the cost of 0.49 USD per sample, in comparison with Promega method (69.19 to 157.68 ng/µL) at 3.28 USD per sample and Geneaid method (8.15 to 18.52 ng/µL) at 2.06 USD per sample. Based on the purity of isolated DNA (A260/280), CTAB method produced relatively similar DNA quality to Promega kit (1.8-2.0). On the other hand, Geneaid method resulted in a lower purity value at 1.15 to 1.60.

Abstract

Red ant (Dorylus orientalis Westwood) is the most destructive insect pest of potato tubers in the field in Nepal. A field experiment was conducted at Bhatkada, Dadeldhura district, Nepal in 2020 to determine the efficacy of various biopesticides and chemical insecticide on red ants. The plot size in this experiment was 106.7 m2. Five treatments viz. Chlorpyriphos 20% EC (2 mL L-1 water), Banmaara (2 kg plot-1), Cow urine (2 L 6 L-1water plot-1), Agave (25 g tuber-1) and Control (no treatment) were evaluated in randomized complete block design with four replications. The data on plant height and the number of leaves were taken at 45, 60, and 75 days after planting (DAP). The data on slightly and severely infested tubers were taken after harvesting of potato. The results showed that Chlorpyriphos treated plots gave the lowest values of traits viz numbers of slightly infested tuber (91,500 ha-1), severely infested tubers (12,500 ha-1), weights of slight infested tubers (7,700 kg ha-1) and severely infested tuber (1,130 kg ha-1). Among the botanical pesticides, Agave treated plots provided the second lowest values of numbers of slightly infested tuber (145,500 ha-1), severely infested tubers (37,400 ha-1), weights of slight infested tubers (13,400 kg ha-1) and severely infested tuber (3,110 kg ha-1). The results showed that the Agave treatment provided the highest marketable yield (50,900 kg ha-1). Thus, Chlorpyriphos and Agave could be used to efficiently protect potato tubers from red ant in potato field.

Abstract

The vast area of paddy crop in Anantnag district (Jammu and Kashmir) has been converted for the construction of houses, roads and especially for horticultural purposes. The cultivation of paddy has been an old cultural heritage of Anantnag district as well as for the Kashmir valley as a whole, while the farmers are increasingly finding it less profitable in recent times. The present study used both primary (Survey) and secondary data from different sources with an aim to highlight the issue of diversifying of food crops (Paddy) towards cash crops (Apple) in district Anantnag. The findings from the study reveal that 6908 hectares of agricultural cropped area is shifted towards the horticultural cropped area, as agricultural crops (paddy) have low comparative advantage over horticultural (Apple). Paddy land under surveyed farmers has registered a significant decrease from 330 canals (83.75%) in 2000-01 to 158 canals (40.11%) in 2014-15, therefore showing an absolute change of -172 canals. The primary survey further reveals that 09 (30%) of the respondents says less profit is the main reason behind the shift, followed by irrigation (drought) problems 07 (23.34%) and 14 (46.66%) respondents says both reasons are responsible behind shift of Paddy to Apple cultivation in the region.
