Abstract

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

Abstract

Storage is one of the post-harvest treatments carried out to maintain seed quality. Cardamom seeds arerecalcitrant seeds that require high moisture content during storage. The research aims to obtain the rightstorage method for maintaining the viability and vigor of cardamom seeds (Amomum compactum Sol. ExMeton; sin. A. cardamomum Roxb.). This study used a factorial, Randomized Complete Block Design (RCBD).The first factor is the storage method, which consists of 4 levels: seed storage with capsules in plasticpackaging, with capsules in paper packaging, without capsules in plastic packaging, and without capsules inpaper packaging. The second factor is the storage period consisting of 4 levels, namely seeds stored for 1, 2,3, and 4 weeks. Observations were made on seed moisture content, germination, growth rate, meangermination time, and maximum growth potential. The results showed that Cardamom seeds retained withtheir capsules experienced a faster deterioration when it was stored in plastic packaging. Seeds withcapsules in plastic packaging had a seedling percentage of 35%, significantly lower than other treatments(51-58%) at 4 weeks of storage. Cardamom seeds can be stored in paper or plastic packaging when theseeds are extracted with noting that the use of paper packaging caused a decrease in seed moisture contentfrom 27.4% to 21.5−22.2%, while the use of plastic packaging can maintain seed moisture content of26.1−26.5%.

Abstract

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.

Abstract

Cayenne pepper is one of the important horticultural commodities and has high economic value for Indonesian people. The demand for cayenne pepper in Indonesia was relatively high, especially for household consumption. Therefore, superior varieties were needed to meet the needs of cayenne pepper in Indonesia. One way to guarantee the superiority of varieties and the validity of variety descriptions was to conduct yield testing. Our research aims to evaluate the performance and yield of seven genotypes of cayenne pepper. This research was carried out from March 2023 to September 2023 at Leuwikopo Experimental Garden, IPB University. It consisted of one factor: ten genotypes (seven genotypes and three control varieties). Experimental design in our research using randomized complete block design with three replications. The results showed that there were differences in performance and yield between cayenne pepper genotypes. The flowering ages of all genotypes ranged from 41.33 - 45.67 DAP with the harvest ages ranging from 83.33 - 92.67 DAP. The percentage of plants observed at the end of harvest ranged from 37.50 - 70.83% with the Rawita F1 variety showing the lowest percentage (37.50%). F1.372340 genotype was the highest productivity genotype, reaching 4.80 t.ha-1. The productivity of F1.372340 was higher than control varieties, which ranged from 1.48 to 2.72 t.ha-1. Line’s genotype had a shelf life ranging from 9.30 - 15.00 DAH which was the same or better than the control varieties which ranged from 9.67-12.33 DAH.

Abstract. Widajati E, Syukur M, Diaguna R, Permatasari OSI, Ritonga AW, Sahid ZD, Pratiwi GR, Hatta ANNL. 2023. Morpho-physiological seed diversity and viability of Indonesian cowpea (Vigna unguiculata). Biodiversitas 24: 5319-5327. Cowpea is a legume with a potential nutritional content almost equivalent to soybeans; it can be developed as a substitute agent for raw materials for food processing. One of the factors in obtaining high cowpea production is to use of quality seeds. Our study aimed to evaluate the performance and morpho-physiological correlations and viability of cowpea seed collections from IPB University Bogor and the Indonesian Research Institute of Legume. We used ten genotypes of cowpea, which had superior seed information. The results showed that the ten cowpea genotypes had superior morpho-physiological and seed viability. The seed germination percentage was categorized as medium-high (>60%). Eight cowpea genotypes were grouped into one major group based on morpho-physiological characteristics and viability. Furthermore, positive correlations were found between the observed variables of seed viability (seed germination, seed growth speed, and seed vigor index). Our research results are useful as a source of genetic diversity for plant breeders in developing new superior varieties in the future. In addition, agronomists can use this information to plant cowpeas based on planting location.

Abstract

[EFFECT OF SEED COATING ON MAINTAINING VIABILITY OF RED GUAVA (Psidium guajava L.) SEEDS DURING STORAGE]. Guava (Psidium guajava L.) is one of the potential intercropping options for a revegetation programme. Hydrophilic polymer coating and several additional materials are expected to increase the vigor of seeds planted by direct sowing under suboptimal conditions. However, it is necessary to study its effect on seed viability during storage, especially on guava seeds which are classified as intermediate seeds.This study aims to determine the effect of coating on the viability of guava seeds (Psidium guajava L.) during storage. The experiment was arranged in a factorial randomized complete block design (RCBD) with two factors: coating materials (control, alginate, tapioca, alginate + manure pelleting, alginate + vermicompost pelleting, tapioca + manure pelleting, and tapioca + vermicompost pelleting) and storage periods (0, 2, and 4 weeks) in polyethylene bags. The results showed that storage for more than two weeks caused a sharp decrease in germination percentage and vigor index. Coating treatment with alginate for two weeks is more effective in maintaining water content, germination percentage, and seed vigor. Seed coating with alginate is recommended method for extending shelf life while maintaining the physiological quality of guava seeds. Pelleting using alginate and vermicomposting were not significantly different from coating treatment with alginate in the same parameters, so both treatments can be recommended as neede
