Abstract
Two field experiments (2005 and 2006 kharif) and one seed storage experiment in
laboratory were conducted at Agricultural Research Station, Mugad, University of
Agricultural Sciences, Dharwad to investigate the influence of organics and integrated
nutrient and pest management on seed yield and quality and storability of scented rice cv.
Mugad Sugandha.
Among the several management practices, integrated nutrient and pest management
(50:50:50 kg NPK /ha + 50% RDN through FYM) recorded better crop growth and higher
seed yield (3775 kg/ha), seed quality traits, net returns (Rs. 51,868/ha) and benefit cost ratio
(3.15) over organic nutrient and pest management and conventional (farmers management)
practices. Hence, it is economically feasible and viable.
Integration of organics (farm yard manure, vermicompost, poultry manure and green
leaf manure) with inorganic fertilizer (50:50:50 kg NPK + 50% recommended dose of N in
the form of FYM/ha) realized higher seed yield (3335 kg/ha). Better quality traits like
germination (97.8%), field emergence (93%) and seedling vigour index (1516) compared to
the application of organic and nutrients alone.
The seed storage experiment results of scented rice revealed that seeds grown either
organically or higher integrated nutrient management and treated with insecticide (malathion
@ 10 g/kg of seed) and fungicide (thiram @ 2 g/kg of seed)/ calcium oxychloride (5 g/kg
seed), arappu leaf powder (25 g/kg seed) stored in 0.1 mm thick polythene bag retained seed
germination more than minimum seed certification standard and higher vigour index more
than 20 months of storage under ambient conditions of Dharwad (Mugad).
Among the botanicals tested for seed treatment for storage of arappu leaf powder
(Albizzia amara) was found to be better in maintaining seed viability and vigour of scented
rice up to 20th month of storage.
