Influence of Various Plant Spacing on Plant Population and Yields of Cotton (Gossypium Arboreum L.)
Abstract
To boost output and lower cotton input costs, a narrow plant spacing production system has been proposed as an alternative to the conventional method. However, more examination through into performance of this production system in various parts of the world's cotton belt may be essential. The field experiment was conducted at Hill Cotton Research Station, Balaghata, Bandarban, Bangladesh during 2020-21 growing season to study the performance of SR 27 Cotton line (Gossypium arboreum L.) beneath numerous plants spacing. The treatments consisted of four plant spacings viz. 90cm × 45cm, 90cm × 30cm, 90cm × 15cm, 90cm × 10cm. The experiment was carried out with a randomized complete block design and repeated 3 times. The highest seed cotton yield (2705kg/ha) and plant number (68107) per hectare, were recorded with spacing of 90cm × 10cm which was significantly(p<0.01) more than 90cm × 45cm, 90cm × 30cm and 90cm ×15cm. But, other parameters like plant height (cm), node number of first fruiting branch (NFB), number of monopodial branches/plant, number of sympodial branch/plant, number of bolls/plant and single boll weight (gm) were statistically non-significant but they play a role in yield. So that, narrow (90cm × 10cm) plant spacing is better than others wider plant spacing for getting maximal seed cotton yield and plant population play a key factor to minimize yield losses.
