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. |
