Abstract
An experiment was conducted with two factors (A) Planting methods viz. P1 - Manual transplanting, P2 -
Parachute technology (B) Nitrogen levels viz. No (control), N1 (25 kg ha'), N2 (50 kg ha"), N3 (75 kg ha"), N4 (100
kg ha'), Ns
(125 kg ha') and N6
(150 kg ha'). Plant height was significantly affected by different N levels. The N6
treatment (150 kg N ha:1
) resul~ed in ~a~i~um plant height (116.55 c~) that is statistica~l~ similar with that of Ns
treatment (125 kg N ha 1) but differs significantly from N4 (100 kg N ha \ N3 (75 kg N ha ) and N2 (50'kg N ha')
showing the plant heights of 111.8 cm, 106.9 cm and 100.3 cm respectively. N, treatment produced maximum
number of productive tillers m-2
(184.27). Maximum leaf area index (5.17) was obtained in Ns. Maximum number
of spikelets panicle' (118.85) was obtained in N6
treatment. Maximum percentage of normal kernels (84.45%)
was obtained in Ns Maximum 1000-kernel weight (21.87 g) was obtained in Ns. Maximum paddy yield (5.15 t ha')
was obtained in Ns
. Minimum. paddy yield (2.75 t ha') was obtained by No. Straw yield was maximum (11.00 t ha")
in case of N6
. Maximum harvest index (31.97%) was recorded by Ns. Both nursery-transplanting techniques
behaved similarly.
