Paper tube nursery technique in Cotton:Timely establishment and enhanced yield

Abstract

Transplanting of cotton has many advantages includes reduces main field duration, maintaining of plant population,  manipulate the time of sowing to achieve optimum time, fitting crop into low length of growing period region, advantage in cropping system by reducing main field duration,  and also suitable for the farm has undesirable quality of irrigation water for germination. Paper tube Nursery technique  was developed  by  following vigorous testing  procedures  during the year of  2013-14 and   2014-15 at Central Institute for Cotton Research, Regional Station, Coimbatore . Subsequently  field trial was conducted during  2015-16 . The field experiment was  attempted  with two method of planting (transplanting and direct sown) and  three  planting times  (27^th August, 15^th September (late planting) , and  5^th October (late planting).The seedling at the age of 21 days was transplanted. The interaction results revealed that 25^th August transplanting registered 15.34 percent higher seed cotton yield as compared to corresponding date of direct sown crop  . However 5^th October transplanting registered enhanced performance of 64.7 percent higher seed cotton yield as compared to corresponding date of direct sown crop. The results revealed that 25^th August transplanting realized 4.8% higher net return but transplanting of 15^th September arrived as 44.4   per cent of higher net return as compared to direct sown of same date respectively. The results concluded that the visible advantage of transplanting observed in late sown situations.
