PARAMESH, RSUMALATHA, G.M.2017-08-072017-08-072015-07-31Th-11160http://krishikosh.egranth.ac.in/handle/1/5810027758The field and laboratory experiments were conducted at Regional Institute on Organic Farming and Department of Seed Science and Technology, UAS, GKVK, Bengaluru, during 2014-2015 to study, the influence of panchagavya on vegetable seed production of cowpea genotypes. The results revealed that PKB-4 recorded highest plant height (75.61 cm), number of branches (5.46) whereas, AV-5 recorded less number of days for 50 % flowering (53.67), highest germination (83.39 %), seedling vigour index-I (2718) seed yield planf1 (14.74 g), cleaned seed yield (1.22 Kg plof1 ). Among different concentrations, panchagavya at 5 % recorded significant improvement in plant height (85.94 cm), number of branches (6.47), less number of days for 50 % flowering (52.67 %), highest germination (88.88 %), seedling vigour index-I (3319), seed yield plant -I (14.80 g), cleaned seed yield (1.27 Kg plof1 ) compared to control. Among harvesting intervals, Subsequent formed pods showed better seed quality parameters viz., germination (84.22 %), seedling vigour index-I (3038), protein (16.78 %) compared to first formed pods. During accelerated ageing test (0 to IO days) after 10 days of test, genotype AV-5 recorded lower reduction of seed quality attributes like germination (3.85 %), seedling vigour index-I (33), total dehydrogenase activity (0.93 OD value), field emergence ( 1. 00 % ) compared . to other genotypes. The investigation revealed that panchagavya at 5 % with subsequent formed pods registered higher seed yield and quality parameters, Irrespective of the genotypes and panchagavya spray, accelerated ageing test revealed progressive decline in seed quality parameters as ageing period advanced.ennullThesis
