Description A field experiment was conducted during kharif 2002 on sandy clay
loam soil at the Agricultural College Farm, Bapatla of Andhra Pradesh to find
out the influence of nitrogen sources and planting methods on productivity
and quality of rice varieties. The experiment was laid out in split plot design
replicated three times with twenty treatment combinations involving two
methods of planting (Direct seeding and transplanting) and two rice varieties
(BPT 8024 and MTU 2077) as main treatments and the sub plot treatments
consisted of five nitrogen management practices (No nitrogen, 100%
recommended nitrogen through fertilizer, 100% recommended nitrogen
through organic source viz., FYM, 50% recommended nitrogen through
fertilizer + 50% recommended nitrogen through FYM and 100%
recommended nitrogen through fertilizer + 25% recommended nitrogen
through FYM).
The results indicated that neither the two planting methods nor the two
varieties had any significant affect on the growth as well as quality parameters
of rice. The interaction affect between the planting methods and varieties was
also non significant.
Among the different nitrogen management practices, combination of
100% recommended nitrogen through fertilizers and 25% recommended
nitrogen through FYM (RDN100 + M25) produced taller plants, increased
number of tillers, dry matter accumulation, panicle length, number of panicles
m-2 and number of filled spikelets per panicle of rice crop which was superior
to other nitrogen management practices except RDN100 and 50%
recommended nitrogen each through fertilizers and FYM (RDN50 + M50-).
Application of RDN100 + M25 has resulted in the highest 1000-grain
weight, grain and straw yield as well as harvest index and nutrient uptake.
Head rice recovery, volume expansion ratio, protein content and
amylose content were the highest with RDN100 + M25 which was however,
comparable with RDN50 + M50 and 100% recommended nitrogen through
fertilizer alone, but distinctly superior to 100% recommended nitrogen through
FYM.
From the present investigation, it can be concluded that transplanting
method proved significantly not superior to direct seeding in respect of growth
and yield of rice. Productivity and quality of rice in respect of nitrogen sources
exhibited significant variations due to application of 100% recommended
nitrogen through fertilizer and 25% nitrogen through FYM and closely followed
by 50% N each through fertilizer as well as FYM.
