DEVARAJU, P.J.ASHWINI, J.P.2021-09-242021-09-242018-08-01Th-12036https://krishikosh.egranth.ac.in/handle/1/5810176184A laboratory study was conducted to study the seed storability of sweet corn as affected by the storage condition, chemical seed treatment and packaging material. The study consisted of two different storage conditions viz., ambient and conditional storage (18-20 °C, 30-40 % RH), four different seed treatments viz., untreated, metalaxyl @ 3 g kg-1, emamectin benzoate @ 40 mg kg-1 and metalaxyl @ 3 g kg-1 + emamectin benzoate @ 40 mg kg-1 and stored in three different packing materials viz., HDPE bag, aluminium pouch and metalized pouch for ten months with FCRD in two replications. Seeds treated with both metalaxyl @ 3 g kg-1 + emamectin benzoate @ 40 mg kg-1, packed in aluminium pouch and stored at conditional storage recorded better seed quality attributes viz., germination (83.75 %), seed moisture content (8.05 %), mean seedling length (21.73 cm), mean seedling dry weight (28.74 mg), seedling vigour index I (1821), electrical conductivity (876.4μS cm-1), total dehydrogenase activity (1.232 A480 nm), seed infestation (2.00 %), total soluble sugars (25.35 μg ml-1), and field emergence (71.25 %) up to ten months of storage compared to other treatments. From the study it is evident that sweet corn seeds could be stored up to ten months with less deterioration in seed quality by treating with both metalaxyl and emamectin benzoate, packed in aluminium pouch and stored at condition storage.EnglishThesis
