Abstract

The aims of this research were to understand the effects of organic nutrients and planting time in intercropping system on growth and yield the maize (Zea mays L.) and peanut (Arachis hypogaea L.). The research was conducted at Experimental Farm and Laboratory of the Faculty of Agriculture, University of Haluoleo Kendari, on July to October 2012. The experiment was arranged in Completely Randomized Block Design (CRBD) in a the split plot design, which consisted of dosage of organic nutrients (S) as main plot, with three levels, S0 without organic nutrients, S1 dose 1 mL L-1 water of organic nutrients and S2 dose 2 mL L-1  water of organic nutrients. Planting time (W) as sub plot, consisted of three levels, W0 = planting time of peanut together with maize, W1= planting time of peanut 10 day before maize and W2 = planting time of peanut 10 day after maize. Combination of treatment was repeated three times. Data obtained were analyzed using analysis of variance and followed by Duncan’s Multiple Range Test. The results showed that the highest maize productivity was 7.31 ton ha-1 and peanuts 2.21 ton ha-1 obtained of the treatment of growth hormone dose of 1 mL L-1  and peanut cultivation 10 day before maize. Treatment of 1 mL L-1 water of organic nutrients and planting time of peanut 10 day before maize can improve growth and yield of maize and peanut crops and thus can be a recommendation in intercropping systems on maize and peanut. Keywords: maize, peanut, growth hormone, planting time in intercropping system

Abstract

This research aimed to examine the relationship between soil pH, exchangeable aluminum (Al-dd), and available phosphorus (P-available) in Ultisol soil through the application of sago waste compost. The research was conducted in a greenhouse located in Wowawanggu Village, Kadia District, Kendari City. Soil analysis was performed at the Laboratorium Dasar Kimia Analitik, Haluoleo University. The study was designed based on a Completely Randomized Design (CRD) with sago waste compost treatment doses, where each treatment was repeated 3 times. The doses of sago waste compost tested consisted of three levels: 10 tons/ha (KAS1), 20 tons/ha (KAS2), and 30 tons/ha (KAS3). Soil analysis was conducted on pH, Al-dd, and P-available before and after the application of sago pulp compost. Observations after application were made in stages every 7 days with four observations. The results showed that the application of sago waste compost had a significant effect on increasing pH and P-available and decreasing Al-dd in Ultisol soil. There was a very strong relationship between pH, P-available, and Al-dd, as indicated by a correlation coefficient value of > 0.90. The best treatment was shown by KAS3, with a sago waste compost dose of 30 tons/ha.

Abstract

An experiment aimed in gaining information on morphological characteristics of Jatropha curcas (L.) containing high frequency of uninucleate microspores has been done. This was important due to the successful application of experiment in haploid technique through anther or microspore culture is strongly determined by the availability of information from basic research such as appropriate morphology of the flowers. This scientific article, in our knowledge, was an early explanation of the initial steps of whole procedures in the microspore culture of Jatropha curcas (L.).  Results of the research showed that the morphological features of flower that contained high frequency of mid- and late uninucleate microspores was that the flowers must be in the range of 2 to 3 mm in length. Such flowers contained yellowish anthers.Key words: Flowers length, mid- and late-uninucleate, morphology, physic nut, microspore

Abstract

The research to study the effects of arbuscular mycorrhiza fungi (AMF) and organic nutrients to enhance the growth of chili has been conducted in Experimental Field, Faculty of Animal Husbandry and laboratory of Agrotechnology, Halu Oleo University, from June to November 2012.  The research was based on the split-plot design with a randomized  block design pattern (RAK) of two factors: Organic Nutrition as the main plot and AMF as subplot. Organic nutrients as the main plot consisted of three levels, namely: without organic nutrition (S0), 1 mL L-1  of water (S1) and 2 mL L -1  of water (S2);   and AMF dose as subplot consisted of three levels, namely: without AMF (M0), 5 g plant-1  (M1) and 10 g plant-1  (M2). therefore, there were 9 combinations of treatments and each treatment combination was repeated  three  times  to  obtain  27  experimental  units.  Each  variable  was  analyzed  by analysis of variance, then followed by Duncan's Multiple Range Test (UJBD) at 95% confidence level. The results of research indicated that the best interaction of   AMF   and organic  nutrient  treatment was 10 g AMF plant-1 (M2) and 2 mL L-1 (S2) of organic nutrients. This treatment combination can improve growth on variables: leaf area, leaf area index and yield index of the chili plants.  The best treatment for AMF independently was at 10 g plant-1 (M2) because it can promoted growth of plant height of the chili plants. The best treatment for organic matter independently was at 2 mL L-1(S2), because it can promoted growth of plant height of the chili plants. Keywords: FMA, organic nutrition, growth, chili

Abstract

The aims of the research were to study the interaction and the independent effects of irrigation frequency and manure on soybean vegetative growth. This research was arranged based on Completely Randomized Block Design in a factorial pattern, consisted of two factors. The first factor was irrigation frequency, consisted of four irrigation frequencies, i.e., 2, 4, 6, and 8 days. The second factor consisted of 3 manure dosages, i.e. without manure, 10 ton ha-1, and 20 ton ha-1. Each treatment was replicated 3 times, therefore, overall there were 36 experimental units. Data were analysed using analysis of variance. The variables observed were: plant height, stem diameter, number of leaves per plant, and leaf area. The result of the reasearch indicated that interaction between irrigation frequency and rate of manure did not affect the vegetative growth.  Independent effect of irrigation frequency and rate of manure occured at plant height, stem diameter, number of leaves per plant, and leaf area per plant. The irrigation frequency of 2 days and manure 10 ton ha-1 significantly affected soybean vegatative growth. Keywords : Soybean, irrigation, manure

Abstract

This research is motivated by the fact that eggplant production is still low because it is triggered by the condition of agricultural land which is less fertile and the limited availability of nutrients. One alternative used to overcome this is liquid organic fertilizer (LOF) from rice washing water. This research aims to determine the effect of LOF made from rice washing water on the growth of eggplant plants and to determine the treatment that has the best effect on the growth of eggplant plants. This research was carried out at the Experimental Garden Field Laboratory II and the Agrotechnology Laboratory, Agronomy Unit, Faculty of Agriculture, Halu Oloe University (HOU) Kendari, Southeast Sulawesi from August to October 2023. The design used was a randomized block design (RBD) with LOF treatment of washing water rice consisting of three levels, namely 150 mL (B1), 300 mL (B2) and 450 mL L-1 water (B3). The variables observed were stem diameter, number of leaves, leaf area, number of branches, flowering age, total dry weight and root shoot ratio (RSR). Data from observations were analyzed using variance analysis (ANOVA) and further testing using Duncan's multiple range test (DMRT) at a confidence level of 95%. The results showed that LOF treatment of rice washing water had a very significant effect on stem diameter at 56 DAP; number of leaves and total leaf area at 14, 28, 42 and 56 DAP; number of branches, and total dry weight. The best treatment to increase the growth of eggplant plants is LOF at a dose of 450 mL L-1 water.
