An experiment was conducted to investigate the influence of packaging materials and seed treatments on storability of cluster bean under ambient conditions of Bengaluru. The experiment consisted of six treatments viz. control (T 1 ), bavistin @ 2 g kg -1 (T 2 ), spinosad @ 0.04 ml/kg (T 3 ), neem leaf powder @ 1:20 ratio (T 4 ), Acorus calamus@ 10 g kg -1 (T 5 ) and cow dung powder @ 10 g kg -1 (T 6 ) and three packaging materials viz., cloth bag (C 1 ) super grain bag (C 2 ) and poly lined cloth bag (C 3 ). Treated seed samples were stored in three containers under ambient storage conditions up to the duration of which seeds maintain minimum seed certification standards and samples were drawn at bimonthly intervals for ascertaining the seed quality parameters. The study suggested that seed treatment could be useful to prolong the storage life of cluster bean seeds. The seeds treated with spinosad (0.04 ml/kg) and stored in super-grain bag were better for maintenance of higher seed quality parameters [germination (80.00%), root length (11.70 cm), shoot length (13.60 cm), mean seedling dry weight (152 mg), seedling vigour index I and II (2024&12140) and TDH activity (1.224) with low electrical conductivity (0.368 dSm )] up to 18 months under ambient conditions of Bengaluru (room temperature). Super-grain bag proved to be better storage container with higher seed quality attributes viz., germination (72.38 %), seedling vigour index-I (1726), total dehydrogenase activity (1.201) and other seed quality parameters compared to cloth bag. The study suggested that use of appropriate packaging material and seed treatment could be useful to prolong the storage life of cluster bean seeds.
An experiment was carried to find out the effect of sowing dates and cutting time on seed yield and quality of alfalfa cv. RL-88. The results of the experiment revealed that, the significantly higher seed yield per plant (1.491 g), seed yield per plot (161.07 g) and seed yield (355.00 kg ha -1 ) was noticed in 15 th August sowing and the cutting carried out at 60 days after sowing. Whereas, the seed quality parameters of the resultant seeds viz., highest seed germination (95.00 %), seedling length (13.90 cm), seedling dry weight (412.69 mg) and seedling vigour index (1320) found highest in15 th August sowing and the cutting followed at 60 days after sowing.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
