Effect of planting date and chemical desuckering on morpho-physiological parameters and yield of Rustica tobacco (Nicotiana rustica L.)

Abstract

The present investigation on “Effect of planting date and chemical desuckering on morpho-physiological parameters and yield of rustica tobacco (Nicotiana rustica L.)” was carried out at Bidi Tobacco Research Station, Anand Agricultural University, Anand, during the year 2017-18.The field experiment was laid out in Factorial Randomized Block Design (FRBD) with three replications comprising twelve treatment combinations of two varieties (GC 1 and DCT 4), two suckericides treatments (hand desuckering and pendimethalin @ 0.60 % + 2 % urea and three transplanting dates (4th week of October, 2nd week of November and 4th week of November). On the basis of research finding, it was observed that variety DCT 4 should be transplanted in 4th week of October and chemically desuckered with pendimethalin @ 0.60%+ urea 2% for obtaining higher yield over hand desuckering in rustica tobacco crop.
