Abstract:
An experiment was conducted at College of Agriculture, Vellayani
during kharif season (June - September 2003) to evaluate the efficiency
of different planting methods and AMF application en the establishment,
growth and yield attributes of rice. The experiment was laid out in split
plot design with five replications. The main treatments were seedling
,
throwing, machine planting and line transplanting methods. The subplot
treatments consisted of AMF application and without AMF application.
Maximum establishment as noticed in line planting. More root
activity, plant height, leaf area index, dry matter production and tillers
were observed in seedling throwing method.
Days to 50 per cent flowering was minimum in machine planting.
Higher number of filled grains per panicle was observed in line planting.
Higher number of productive tillers, panicles m-2 and straw yield was
observed in seedling throwing method. Higher grain yield was observed
in seedling throwing and line planting methods. Maximum harvest index
was noticed in line planting. Higher uptake was noticed in seedling
throwing method.
AMF inoculated plants show~d supenor trends in establishment
plant height, leaf area index, drymatter production, number of
productive tillers, panicles m ", filled grains panicle.", 1000 grain
,eUEbt. grain yield and straw yield.
Higher gross return and net return was observed in seedling
ing method. In machine planting and see~ling throwing there was
high labour saving compared to line planting .. High B : C ratio, gross
turn and net return were observed in AMF inoculated plants.
Machine planting of seedlings raised in AMF inoculated mat
nursery, at a spacing of 30 x 10 cm followed by seedling throwing of
MF inoculated seedlings recorded higher B : C ratio.
