REDGRAM, TRANSPLANTED
 
Description A field experiment was conducted during kharif, 2010 on a coastal sandy
clay loam soil of the Agricultural College Farm, Bapatla to study the
“Performance of redgram cultivars under transplanted conditions”. The
experiment was laid in Randomized Block Design with factorial concept having
12 treatments and replicated thrice using 3 redgram varieties viz., LRG-41, PRG-
158 and WRG-53 and 4 ages of seedlings viz., conventional sowing, 15, 30 and
45 day aged seedlings.
Results of the experiment indicated that neither redgram varieties, age of
seedlings nor their interaction could influence initial and final plant stands and
survival percentage.
Among the growth parameters, plant height was not influenced by redgram
varieties or age of seedlings while, primary and secondary branches were
significantly influenced by seedlings age. Drymatter production measured at
different intervals and days to 50 per cent flowering were influenced by redgram
varieties, age of seedlings and their interaction while days to maturity was
influenced only by redgram varieties. Significantly the highest number of primary
(19) and secondary (25) branches plant-1 were registered by transplanting 15 day
aged seedlings.
At all the phases of redgram crop growth, transplanting 15 day aged
seedlings of LRG-41 variety registered significantly the highest drymatter
production of 375, 1683 and 12369 kg ha-1 at 60, 90 DAT and at harvest,
respectively compared to other treatment combinations. Transplanting 45 day
aged seedlings of PRG-158 variety registered significantly the lowest drymatter
production.
Conventional sowing of PRG-158 variety took significantly the lowest
number of days (100) for 50 per cent flowering, while, LRG-41 variety took
significantly the highest number of days (208) to mature over other age of
seedlings.
Yield attributes like number of pods plant-1 were significantly influenced
by varieties, age of seedlings and their interaction while, number of seeds pod-1
were non significant. Test weight and harvest index were significantly influenced
by varieties and age of seedlings. Seed and stalk yields were influenced by
varieties, age of seedlings and their interaction. Transplanting 15 day aged
seedlings of LRG-41 variety recorded significantly the highest number of pods
plant-1 (295) and transplanting 45 day aged seedlings of PRG-158 variety
registered the lowest number of pods plant-1 (229). Among the varieties,
LRG-41recorded significantly the highest test weight (9.8 g) over other varieties
and transplanting 15 day aged seedlings recorded significantly the highest test
weight (9.9 g) over other aged seedlings.
Transplanting 15 day aged seedlings of LRG-41 variety recorded
significantly the highest seed yield (2057 kg ha-1) and stalk yield (10312 kg ha-1)
and transplanting 45 day aged seedlings of PRG-158 variety recorded the lowest
seed yield (1526 kg ha-1) and stalk yield (9200 kg ha-1). LRG-41 variety recorded
significantly the highest harvest index (16.8) over other varieties and transplanting
15 day aged seedlings recorded significantly the highest harvest index (15.9) over
other aged seedlings.
NPK uptake was significantly influenced by varieties and age of seedlings
only. LRG-41 variety recorded significantly the highest NPK uptake i.e. 200.6,
26.1 and 63.6 kg ha,-1 respectively compared to other varieties and transplanting
15 day aged seedlings recorded significantly the highest NPK uptake i.e. 206.8,
26.2 and 64.8 kg ha,-1 respectively, compared to other aged seedlings.
The higher gross returns (76,136 Rs. ha-1) and higher net returns
(59,686 Rs.ha-1) and returns per rupee investment of 3.62 was recorded by
transplanting 15 day aged seedlings of LRG-41 variety.
From the results of the present investigation, it can be concluded that
LRG-41redgram variety transplanted with 15 day aged seedlings performed better
with higher growth parameters, yield attributes and yield, nutrient uptake and
monetary returns over other treatment combinations.
