Description |
The present investigation on “Effect of date of sowing and nitrogen on growth and yield of Isabgol (Plantago ovata Forsk.)” was conducted at Herbal Garden, ANGRAU, Rajendranagar, Hyderabad during the period from October 2004 to March 2005. The experiment was laid out in randomized block design with factorial concept. In the present study, 5th October sowing proved to be superior over other sowing dates in respect of plant height (42.34 cm), number of tillers per plant (12.26), dry weight of plant (5.05 g), spike length (5.34 cm) and seed yield per hectare (5.49 q ha-1). Among the different levels of nitrogen, 100 kg ha-1 recorded higher plant height (34.58 cm), greater number of tillers per plant (10.34), higher dry weight of plants (4.78 g), spike length (4.44 cm) and seed yield per hectare (41.10 q ha-1) over other levels of nitrogen. The interaction between sowing dates and nitrogen levels revealed that the plant height (44.27 cm), number of tillers per plant (13.06), dry weight of plant (7.23 g), spike length 96.20 cm) and seed yield per hectare (5.64 q ha-1) were maximum with 5th October sowing + 100 kg N ha-1 over other treatment combinations. The harvest index was on a par with 5th October sowing (5.15) and 20th October sowing (5.10) but were significantly superior over 5th November sowing (4.46) and 20th November sowing (3.99). Among the nitrogen levels, 75 kg N ha-1 recorded higher harvest index (5.37) over other nitrogen levels. The interaction between sowing dates and nitrogen levels revealed that harvest index was maximum with 5th October sowing + 75 kg N ha-1 (5.89). The percentage of husk did not differ significantly because of different sowing dates. Further, the treatment with no nitrogen recorded significantly higher percentage of husk (23.85) over 100 (21.85) and 50 kg N ha-1 (21.83) but was on a par with lower levels of nitrogen 75 kg N ha-1 (22.30). The treatment combination, 5th October sowing + 75 kg N ha-1 (24.50) recorded high percentage of husk but was on a par with all the treatment combinations except at 20th November sowing with all the nitrogen levels. The present study revealed that 5th October sowing in combination with either 100 kg N ha-1 or 75 kg N ha-1 recorded higher yield over all other treatment combinations. This could be due to congenial temperature (22.42oC) more sunshine hours (189.60 hrs), higher relative humidity (85%) and high rainfall (112.70 mm) during the crop growth period. Further sowing on 20th November recorded lower growth parameters resulting in lower yield irrespective of nitrogen levels. This might be due to low mean minimum temperature (13.63oC) and low rainfall (36 mm) coupled with short day condition during the plant growth period. |
