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.

The experiment was conducted to investigate the seed quality of Indian spinach for three months stored at different containers (Plastic pot, polythene bag and cloth bag) during 2013-2014 at Seed Technology Laboratory of Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur. The initial moisture content of the seed was 9.89% with 75.00% germination. However, after two months, the seed had a different range of increased moisture content with reduced germination percentage depending upon the packing materials. Among the three containers, seeds stored at cloth bag absorbed more moisture (14.36%) from surrounding atmosphere followed by the moisture content, 12.67% and 11.50% of polythene bag and airtight plastic pot, respectively. Seeds stored at plastic pot, polythene bag and cloth bag exhibited 65.00, 64.00 and 50.00 per cent germination, respectively. Similarly, the fresh weight and dry weight of seedling and seedling vigor were also decreased. The seeds of plastic pot were good in term of germination capacity, fresh and dry weight and vigor index in comparison to those stored at cloth bag and polythene bag.Int. J. Agril. Res.

East Gojjam is one of the major tef seed growing areas of Ethiopia. The main themes of this study were to assess the physical, physiological and health quality of seed in Gozzamin and Enarji Enawga districts, Amhara Regional state, in 2009/2010 cropping season. Data were done by employing SAS (9.0) softwares to analyse the physical, physiological and health quality of seed samples. There was a significat difference in physical purity among seed samples. The analytical purity of the tef seed grown in all PAs was above the national standards for commercial seed. The most abundant seeds of other species in purity analysis were Vitgroe, Sitaria spp, Trampgrass samples which appeared in 31% (4), 23% (3) and 15% (2), respectively. The overall average mean germination percentage was 88.2% with the range of 76.6% to 93.0% and the highest value was recorded for seed obtained from Enarji Enawga F8 (93.0%) followed by F1 (92.3) from Gozzamin. The lowest vigor index 1 was recorded for F7 from Enarji Enawga because of short root length (199.99cm). The highest vigor index II was recorded for samples collected from ESE with 1.68mg mean because of higher seedling dry weight. There was a positive and highly significant correlation (r = 0.603**, p < 0.001) between germination percent and seedling emergence percent. These indicated that as the germination percent increased and seedling emergence percent also increased. Seed storage facilities at farmers are inferior to those at the Ethiopian Seed Enterprise but during shipments should therefore be timed so that seeds can be sown with the minimum delay after receipt. So, shipment of sensitive seeds by air is desirable. Other, wise in conclusion, to enhance tef productivity in east Gojjam zone through supply of improved varieties and quality seed it is important to integrate formal and farmer (informal) seed system.

Chickpea Cultivars

AbstractA split plot experiment (using RCB design) with three replications was conducted in 2012 and seed physiological quality of three chickpea (Cicer arietinumL.) cultivars (Azad, Arman and Jame) was evaluated at seven stages under well and limited irrigation conditions. Maximum seed weight (mass maturity) was achieved at 40–45 days after flowering. However, maximum seed quality was obtained 7 to 10 days after mass maturity, depending on irrigation intervals and cultivars. At earlier harvests, because of immaturity, and at later harvests, due to ageing, seed quality was low. Seed filling rate and maximum seed weight of chickpea decreased with decreasing water supply, but water deficit had no significant effects on seed quality as measured by germination percentage, germination rate and seedling dry weight. Significant differences in seedling dry weight among chickpea cultivars were attributed to significant variation in seed weight affected by genetic constitution.
