ABSTRACTThe use of high quality seed is one of the key factors to improve productivity. Probiotic bacteria has been used to increase plant growth and to control pathogens. The objective of the research was to evaluate methods of chili seed production that yielded high physiological and pathological quality using probiotic fluorescent bacteria Pseudomonas (P24). The bacteria was expected to function as plant growth promoting bacteria as well as capable of controling seedborne pathogen Colletotrichum acutatum causes antrachnose. The experiment was conducted during March until October 2014 in Seed Health Laboratory, Plant Bacteriology Laboratory, and Leuwikopo experimental garden, IPB. The experiment was arranged in a split plot randomized complete block design with three replications. The main plots were untreated and inoculation of C. acutatum. The subplot was six treatments of fluorescent Pseudomonas (P24) application. The results showed that matriconditioning and spraying of fluorescent Pseudomonas (P24) on nursery decreased disease incidence significantly. Matriconditioning and spraying of fluorescent Pseudomonas (P24) on nursery and flowering phase increased number of healthy fruit and total weight of seeds per plant significantly. These applications also increased seed physiological quality indicated by germination percentage (GP) 77.04%, growth rate (GR) 9.72% etmal-1, vigor index (VI) 29.74%, and seed health by suppresed C. acutatum infection up to 12.25%.Keywords: anthracnose, Colletotrichum acutatum, control, matriconditioning, spraying

True shallot seeds are preferable to tubers as planting materials because of their advantages in storage longevity, lower management cost, and lower seed-borne disease risk. However, environmentally limited production and seed deterioration in uncontrolled storage have limited its application. Pre-sowing hydration invigoration accelerates and synchronizes the germination of deteriorated seeds. Ultra-fine bubble water (UFBW) contains reactive oxygen species, which can advance the pre-germinative metabolism of the seed. This study examined true shallot seed invigoration using UFBW. The experiment was conducted in a two-factor of randomized complete block design. The first factor was initial seed vigor based on the vigor index with six levels, i.e., 24, 15, 13, 12, 10, and 9%. The second factor was the invigoration treatment of UFBW (8 and 23 ppm dissolved oxygen concentrations) with two durations (24 and 48 h), 50 ppm GA3, and 3% KNO3 (24 h). UFBW with 23 ppm invigoration for 48 h improved seed vigor based on all vigor parameters. The GA3 50 ppm treatment is the most effective in increasing seed vigor. Keywords: dissolved oxygen; pre-sowing hydration; reactive oxygen species; seed viability; seed vigor

Andaliman is a species found in the Lake Toba region of North Sumatra, Indonesia. To determine its optimal harvest time and the length of its physiological maturity, it is necessary to observe fruit development in new locations outside its natural habitat. Andaliman seeds are known for their low germination rates and are classified as endospermic seeds. This study aims to analyze the stages of fruit and seed development, evaluate the effects of seed treatments, and identify the most effective germination test methods for andaliman seeds. Seeds were treated with a 50% H2SO4 solution for 15 min and with a 200 ppm GA3 + 100 ppm kinetin solution for 48 hr. The seeds were then tested using pleated paper and top paper media to assess germination response. Changes in fruit coloration indicated various stages of development: intense yellowish-green at 17 weeks after anthesis, deep yellowish-green at 20 weeks, deep red at 23 weeks, and dark greyish-yellowish-brown at 26 weeks. During development, some fruits experienced embryo abortion, resulting in many empty or wrinkled seeds. The seeds reached physiological maturity at 23 weeks after anthesis, as indicated by a deep red fruit color, increased seed dry weight, and enhanced germination and seed growth rates. The treatment with GA3 and kinetin yielded the highest germination rate of 20%, with the pleated paper method proving to be the most effective for germination testing.

Bogor is one of the centers of taro production, but productivity is low. It was caused by the use of low-quality seeds. The use of good quality of seed will increase taro productivity and production. Good quality seeds were uniform in size, clean, free from other varieties, and had high viability (vigor). This training was aimed at capturing the taro farmer's condition, cultivation technique, and knowledge about good quality of seed. The training was conducted in KTD Saluyu from August to September 2022 and was attended by 25 farmers. Training activities included expert presentations, discussions, and interviews. Evaluation of farmer knowledge change was determined by pre- and post-tests, while the effectiveness of training activities was evaluated to improve its effectiveness in the future. Taro farmers were dominated by men, aged about 40–59 years old (58.3%) and more than 60 years old, and almost all of their education background was elementary school. Farmers cultivated taro by sharing profit land (58.3%), ownership land (33.3%), and rent land (8.3%). Taro production was dominated by less than 1 ton, the monoculture system about 66.7%, and intercropping about 33.3%. Planting material was by farmer own seed from the previous season because there were limited certified seeds. Farmer knowledge increased by about 45.8% (from 4.9 to 7.2). This training was held under good management, as shown by the training evaluation score of about 90%. This training requires that it be held more intensively and sustainably through intensive assistance in the field and a seed production demonstration.
