Abstract

The objective of the research was to determine the host alternate of Potyvirus in Southeast Sulawesi using a host range technique. Observed variables were incubation period, disease incidence, and variation symptom. The research results showed that virus isolates could be mechanically transmitted to melon plant (Cucumismelo) but showing no external symptoms while on tomato (Solanum lycopersicum), long-beans (Vigna sinensis), tobacco (Nicotiana tabacum and Nicotiana benthamiana), swamp-land (Ipomoea reptana), red-amaranth (Alternantheraamoena), chili (Capsicum annum), and egg plant (Solanum melongena) so far the existence of the Potyvirus could not be detected after mechanically inoculated.

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

Soybean (Glycine max (L.) Merr.) is a legume plant that has high economic value containing 20 % fat and 40 % protein. Soybeans are used in a variety of industries, both for food industry and for livestock feed. This research aimed to determine the partition of photosynthates of some soybean cultivars on Ultisol of Poasia, Anduonohu in 2013. The experiment was conducted using polybags filled with 15 kg top soil that had been dried for 2 days. The experiment was conducted using 10 treatments (cultivars) and repeated 3 times so there were 30 experimental units. Each experimental consisted of 12 polybags so there were 360 polybags. Four seeds were sown in each polybag, and thinning was performed at the age of 2 weeks and left only two crops to grow. The research results showed that each cultivar has different photosynthate partitioning. In general, all cultivars provided the highest photosynthate partitioning to leaves and stems until the age of 75 day after planting during the vegetatif phase and into flowers and pods on the generatif phase. Burangram cultivar provided the highest photosynthate partitioning into the pods followed by cultivars Argomulyo, Grobogan, and Kaba.
