Abstract In some areas, farmers sometimes delay planting due to several factors, including: unfavorable climate, unprepared land and insufficient manpower so that planting takes a long time. As a result, seeds that have been given a fungicide cannot be planted and stored under uncontrolled conditions, both at the place and temperature of the storage room. Therefore, the purpose of this study was to determine the storage resistance of seeds that have been given a fungicide (saromyl) so that they can be used as a reference for storing seeds of saromyl. The research was carried out in June - December 2020 at the seed quality testing laboratory of the Cereal Crops Research Institute (Balitsereal), Maros, South Sulawesi Province. The corn seeds used in the study were Bisma 2018 and 2019, Sukmaraga 2017 and 2019, Srikandi Kuning 2018 and 2019, Lamuru 2017 and 2019 varieties. Observations were made on 1000 grain weight, moisture content, electrical conductivity, maximum growth potential, seed growth speed, length of primary root, length of shoot and number of secondary roots. This study used a completely randomized design with 4 replications. The results showed that at room temperature storage (25-26°C and relative humidity 50-58%) the seeds that had been given a fungicide (saromil) with a storage period of 21 days still had high seed quality. Even at low temperature storage (18-18.9°C and Rh 50-55%) during the 6-month storage period, the quality of the seeds was very good. The shelf life of seeds that have been given a fungicide (saromil), is influenced by the shelf life of the seeds, the temperature and relative humidity of the storage room.

Foxtail millet is annual grasses with grains that are smaller than those of sorghum, rice, and wheat, and is considered one of the minor economic crops but with nutritional values similar to other major food crops. The development of millet as major cereal crop is considered challenging due to the low quality of its seeds, and studies have been conducted to improve millet’s seed quality. We conducted this study to determine the harvesting criteria of foxtail millet seeds based on the change in color of the panicles. We also wanted to determine the drying treatment, and evaluate the relationship between the position of the seed on the panicles and the seed viability and vigor. The first experiment was arranged based on a completely randomized design with panicle color as the first factor (green, yellow 75%, and brown) and drying time as the second factor (0 hours, 24 hours, 48 hours, 72 hours). The second experiment was arranged in a completely randomized design with seed position as the main factor (base, middle, tip). The study was conducted on two genotypes of millet, i.e. “BOTOK 4” and “BOTOK 10”. The highest seed quality of “BOTOK 4” and “BOTOK 10” genotypes were obtained when the panicles were brown and dried for 72 hours; the seed chlorophyll content was the lowest and water content was 8.88%, with the highest viability and vigor, i.e., germination rate of 88.3%-90%, maximum growth potential of 92%-95.3%, normal sprout dry weight 596-620 mg, vigor index of 33.6% - 21.6%, and growth rate of 18.2%-17.1% etmal-1. The highest seed viability and vigor in “BOTOK 4” genotypes were obtained from the base position, i.e., 78.7% germination rate, maximum growth potential of 83.7%, vigor index of 56.5%, growth speed of 19.6 etmal-1, normal sprout dry weight of 48 mg, radicle length of 3.3 cm) and “BOTOK 10” genotypes from the middle position with 91.5% germination, maximum growth potential of 97.2%, vigor index  of 21.7%, growth speed of 17.0% etmal-1, and normal sprout dry weight 61 mg.

Aim: To assess the efficiency of ethylene synthesis and action inhibitors on postharvest shelf life of guava fruits under ambient conditions. Methodology: Mature green guava fruits (P. guajava L. cv. Arka Mridula) were harvested and treated with ethylene inhibitors. Various physiological, physical and nutritional changes of the treated fruits in comparison with untreated ones were monitored during ambient temperature storage. Multivariate analysis approach was used for interpreting the data on quality changes during storage. Results: Significant positive correlation (p<0.01) was observed among rates of ethylene production, respiration, ripening and Hunter’s a* value. Biplot from principal component analysis of eleven parameters showed that 1-MCP (500 ppb) treated fruits were grouped together with freshly harvested fruits throughout storage period, and proved superior over other treatments in delaying ripening and quality maintenance. Seven days stored 3.0 mM Salicylic acid and 1.5 mM Sodium nitroprusside treated fruits were grouped together with 5 days stored control fruits, suggesting their effectiveness in extending the shelf life by additional two days. Interpretation: Postharvest application of 1-MCP on guava fruits can extend the shelf life by four days when compared with control. Even PCA indicated that the study of major ripening attributes (L*, a*, b*, Hue, texture, acidity, ethylene rate and respiration rate) was quite sufficient to know the ripening status of the fruits.

Abstract Successful crop production depends initially on the availability of high-quality seed. Seed viability and vigour of four kenaf varieties during storage were investigated. Seeds of each variety were packed inside thick polythene bags and kept in Seed Stores under ambient conditions in two storage locations (Federal University of Agriculture, Abeokuta (FUNAAB) (29.8°C, 59.10 RH%) and Institute of Agricultural Research and Training, Ibadan (27.5°C, 64.68 RH%) for 240 days (8 months). Seeds were sampled during storage at 0, 60, 120, 180 and 240 days and tested for seed viability and seedling vigour index. Data collected on seed viability and seedling vigour were analyzed using ANOVA, mean separation using Duncan Multiple Range Test at 5% probability level and PROBIT analysis. The results showed differential responses in the two quality traits due to differences in storage location and varieties. Ibadan storage location provided more favourable conditions for higher seed quality compared to Abeokuta location while Ifeken 400 and Tianung had the best storage potential. The study showed that under ambient humid tropical conditions, storage period should not exceed 180 days (6 months) in order to maintain higher physiological quality with little or no cost. The PROBIT result revealed that the highest seed shelf life (longevity) of kenaf seeds of 8 to 9 months was derived for seeds of Ifeken 400 and Tianung stored in Ibadan and Abeokuta. The shortest shelf life of 6 months was estimated for Ifeken 100 stored in both locations.
