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

The taxonomic study of a plant is an important aspect of plant research, as it allows the most complete view of the natural habitat of any plant species. The main purpose of the present work is to provide a detail investigation of the Passiflora edulis var. flavicarpa Deg. carried out from the month of April, 2020, growing in the area of Nakachari, Jorhat District, Assam, India. A complete workout on the different parts of the plant belongs to the family Passifloraceae is done to understand the significance of these features in systematic. Paper also reflects the various phytochemical constituents present in the Passiflora fruit also commonly known as Passion fruit which is utilized in pharmacology and by other ways in different ethnic groups of North Eastern India as a vital source of medicinal treatment. The findings clearly express that Passiflora species exhibits all advanced morphological characteristics of present day Angiospermae land plants and also reported that tendrils perform the role of physical support. Towards the end the study it is also concludes with the beneficial outputs of Passiflora edulis from the agronomical point of view that can be easily achievable if the input through cultivation would be uniform as well as dynamic. Based on the various literature surveys, it was found that such detail taxonomic works on the species were not studied and recorded from the study area earlier. Such comprehensive work on Passiflora edulis var. flavicarpa provides an empirical basis for the identification of the species.

Abstract

A trial was conducted to study the physiological responses of baby corn to changes in soil fertility by application of organic and inorganic fertilizers.  The research was conducted at the Teaching Farm, Faculty of Agriculture, Universitas Hasanuddin from May to August 2020. The experiment was arranged based on a factorial randomized block design (RBD) with two factors repeated 3 times. The first factor is the dosage of green compost consisted of four levels, namely 0, 3, 4, and 5 tons ha-1. The second factor was the percentage of NPK fertilization from the recommendations consisted of four levels, namely NPK 100%, 75%, 50%, and 25%. The results show that the treatment of 4 ton ha-1 of green compost resulted in the highest absorption rate of CO2 (336.2 µmol CO2 mol-1) and the highest humidity level (68.8%). 100% NPK fertilizer treatment showed the highest CO2 absorption rate (338.1 µmol CO2 mol-1), the highest leaf photosynthesis rate (36.1 µmol CO2m-2s-1). The treatment of 5 ton ha-1 of green compost and 100% NPK fertilizer resulted in the lowest transpiration rate (0.20 liters m-2s-1). The treatment of 3 ton ha-1 green compost and 100% NPK fertilizer resulted in earlier flowering age (46.3 days) and heaviest ear weight (63.67 g). The treatment of 5 ton ha-1 green compost with 50% NPK fertilizer resulted in the longest ear length with husk (21.72 cm). Treatment of 4 ton ha-1 green compost with 100% NPK fertilization resulted in the longest ear length without husk (10.52 cm).

Abstract

Pest control by using chemical pesticides continuously can harm the environment. Therefore it is necessary to look for environmentally friendly technologies, one of which is the use of entomopathogenic fungi such as Metarhizium anisopliae. The alternative media should be easy to obtain and has a good shelf life so the growth of M. anisopliae   should be optimum. This research aimed to obtain alternative media that provide the best growth and development at each different shelf-life. The research method used was an experimental method using a Completely Randomized Design (CRD) Factorial and it was repeated 4 times. The media factors were from PDA, bran, green beans, and maize. The shelf-life factors were at 21 and 42 days old (d-old). The diameter on maize media gave the highest diameter value of 8.57 cm at 42 d-old. Green bean media gave the best spore density results of 2.08×107. Whereas the germination capacity of the media ranged from 63.94% to 94.23%. Germination showed no significant difference at 21 and 42 d-old. Therefore, green beans and maize media were effectively used for propagation of M. anisopliae   as a substitute for synthetic media.

Abstract

The Nigerian economy largely depends on agriculture which is vulnerable to unfavorable climatic conditions. Consequently, rice is a very important staple crop, widely cultivated and consume by millions of people in the country. Nigerian government policy heavily protects rice in order to stimulate it local production. There is still scanty empirical evidence on the effect of climate change on rice production in Nigeria. This study was carried out to fill this gap. This study specifically examined the effect of climate change on rice output in Nigeria. This study utilized climate data (rainfall and temperature) from Nigerian Meteorological Center, Carbon dioxide data from FAOSTAT, and information on the country’s` milled rice from USDA (1970-2016). The analytical tools employed in the data analysis were Descriptive, Trend analysis, Unit root test, Co-integration and Regression model. Findings of the study revealed that there is variation in the trend of the climatic factors and also variation in rice output over the period of study. The result also shows that that annual rainfall, and temperature contributes significantly to rice output in Nigeria. Rainfall had positive coefficient and significant 5%, temperature had negative coefficient and significant at 1%. The area of land cultivated had positive coefficient and significant at 1%. The study concluded that climate change significantly influence rice output in Nigeria. The study recommended that consideration be given to climate change in the formulation of agricultural policies for the attainment of food security and national aspiration for sustainability in the production of rice production in Nigeria.

Abstract

Effect of the application of individual and combination of vermicompost, NPK along with H2O2 was studied on 10, 20, 30, and 40 days old seedlings of Abelmoschus esculentus. The physio chemical characters of soil with vermicompost showed better result and it has all kinds of nutrient needed for the better growth of the crop. It increases soil fertility, crop production and nutrient content of the plants. Integrated fertilizer application will boost the crop and this is the best way to obtain better results and it will decrease the pollution load on our environment. Application of H2O2 also influences the germination, early plant growth and nutrient content. It act as a growth promoter, but the continuous application and accumulation leads to damages, and the disease resistance against pathogens was decreased during the reproductive stages.
