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

This study aimed to determine the effect of each component of cultivation technology application on the production of rice (Oryza Sativa L.) in South Sulawesi. This research was carried out in three rain-type sectors within South Sulawesi Province, namely Maros for the West Sector, Bone for the East Sector, and North Luwu for the Transitional sector. A study was conducted from December 2019 to January 2020 in the form of a survey (study literature, observation, and interviews), with the selection of samples carried out purposively to 90 respondents. Data analysis employed multiple linear regression with SPSS software. The results showed that the average rice production in Maros, Bone and North Luwu regencies, South Sulawesi, was still relatively low, Maros Regency was 7,032 kg per ha, Bone was 5,020 kg per ha and North Luwu was 6,497 kg per ha. The multiple regression equation for rice production in Maros, Bone and North Luwu Regencies, South Sulawesi is Y = 3354,185 -17,751X1 – 4,044X2 +36,839X3 . Factors from the aspect of cultivation technology application can increase rice production. Variables of cropping system, irrigation system, and fertilizer dose had a significant effect on rice production, while the variables of varieties and harvest time did not have a significant effect on rice production.

Abstract

Doubled haploid plants are very important for the development of complete homozygous plants from heterozygous parents in one generation as they possess duplicate copy of haploid chromosome. Haploid production is easily obtained from in vitro anther culture. The present study was undertaken with the objective to develop doubled haploids using anthers for in vitro induction of callus on N6 medium supplemented with various combinations and concentrations of 2,4-dichlorophenoxy acetic acid (2,4-D) (0.5-2.5 mg/L), Kinetin (0.5-1.0 mg/L) and Naphthalene acetic acid (NAA) (2.0 mg/L) as callus induction medium (CIM). The highest callus induction frequency was obtained when N6 medium fortified with 2,4-D (2.5 mg/L), Kinetin (0.5 mg/L) and NAA (2 mg/L) of 10.07 per cent. The induced callus was sub cultured for shoot regeneration on Murashige and Skoog medium (MS) supplemented with growth regulators: Kinetin and NAA (0.5 mg/L each) in combination with BAP (0.0 - 2.5 mg/L). MS medium supplemented with NAA (0.5 mg/L), Kinetin (0.5 mg/L) and BAP (1.5 mg/L) was most responsive exhibiting regeneration frequency of 28.1 per cent which resulted in maximum regeneration of green plantlets and only 5.21 per cent of albinos. Individual plantlets were separated and immersed in liquid MS medium augmented with NAA (0.5-1.0 mg/L) and BAP (0.5-1.0 mg/L). Maximum rooting was observed in MS medium with NAA (0.5 mg/L) and BAP (1.0 mg/L). The survival rate of in-vitro raised plants was 51.51 per cent. Of these surviving plants, 21 plants were observed to have the sterility percentage above 50 percent and hence can be considered as the doubled haploid plants. Plant DH8 is susceptible and DH20 is heterozygous for gene Xa21. Two plants are susceptible for gene xa13

Abstract

The tendency of chemical fertilizers used (inorganic) in food crop cultivation farming by the farmers is caused by their practicality. However, the continuous use of chemical fertilizers can damage the crops and their environment, including sweet corn. Sweet corn (Zea mays L. Saccharate) contains high sugar content because it naturally mutates to a recessive gene that controls sugar conversion to starch in corn endosperm. The purpose of this research were to know the effect of several organic fertilizers on productivity increase as well as Brix content of sweet corn. This research was conducted from June to August 2021 in Waempubbu Village, Amali District, Bone Regency and Laboratory of Food Process, Agriculture Faculty, Hasanuddin University, South Sulawesi. This research used the design of a split plot by using completely randomized design (CRD). The main plot was sweet corn varieties: Talenta (v1) and Bonanza (v2). Meanwhile, the subplot was organic fertilizers which are control (p0), compost (p1), soil ameliorant (p2), compost + soil ameliorant (p3), liquid organic fertilizer/LOF (p4), compost + LOF (p5), soil ameliorant + LOF (p6) and compost + soil ameliorant + LOF (p7). According to the results, the Bonanza variety showed high average productivity, 22.50 tons per hectare.  The treatment of organic fertilizer that reveals the high average productivity is combines compost + soil ameliorant + LOF (p7). The interaction of treatment that reveals the highest productivity is an interaction between Bonanza variety with the treatment of soil ameliorant + LOF (p6), which is 27.07 tons per hectare with Relative Agronomic Effectiveness (RAE) value is 1366.67%. The treatment of compost fertilizer + soil ameliorant + LOF (p7) exhibits the content of Brix (10.50%) and becomes the highest productivity.

Abstract

The occurrence of conversion of agricultural land can cause erosion proneness, low fertility soils, and decreased land productivity. Land conversion requires an evaluation of land capability, as a basis for direction to maintain land productivity. This study aims to determine the rate of conversion of agricultural land, land capability class, the determinants of land capability, and direction of land management on initial land and converted land in agricultural land, Nguntoronadi District, Karanganyar Regency. The method used is a survey, with the research area divided into 6 LMU (Land Map Units) represented by 6 sample points in each LMU including 3 points on fixed land and 3 points on converted land, resulting in 36 samples determined by purposive sampling. The research stages include; 1) Pre survey, 2) Survey, 3) Post survey. The results of the study show that the land-use change from 2011 to 2020 covers an area of 258.56 ha and a rate of 28.73 ha per year. The land capability of the research area on fixed land and converted land is classified into land capability III and class IV. Factors that determine land capability include soil erodibility and drainage. The recommended direction for land use and management for Nguntoronadi District is the provision of green manure, making terracing, and making drainage irrigation
