Abstract

Cotton is a premier cash crop of India. One of the major constraints in realizing the potential yield of Bt. Cotton is due to non-adoption of package of practices recommended by Punjab Agricultural University, Ludhiana. To bridge this gap, Krishi Vigyan Kendra, Moga had conducted frontline demonstrations at farmer’s fields. The present study was conducted to analyze the yield gaps between recommended package of practices under frontline demonstrations and farmers practice in cotton crop cultivation. Improved cultivation practices comprised under FLD viz. use of improved variety, timely sowing, spray of 2% potassium nitrate and need based application of pesticides observing ETL showed that percent increase in cotton yield ranged from 3.6 percent to 24.5 percent averaging 15.5 percent during the period under study. Technology index decreased from 32.8 percent in 2007-08 to 11 percent in 2010-11 showed the feasibility of Bt. cotton at farmer’s field. Average extension gap of 2.6 q/ha observed during study period emphasized the need to educate farmers through various methods for adoption of recommended package of practices.

Key words: Cotton, Frontline demonstrations, Technology gap, Extension gap, Technology index

Introduction

Cotton is a premium cash crop of India. India is the second largest producer of cotton crop in the world accounting for about 21% of the world cotton production. India has the distinction of having the largest area under cotton cultivation in the world ranging between 10 million to 11 million hectares, constituting about 34% of the world area under cotton cultivation (Anonymous, 2012). Although the cotton productivity in India is significantly lesser than the world average, but it has been doubled in the current decade to 554 kg per hectare. One of the important contributing factors is the introduction of Bt cotton technology in managing insect - pests of cotton crop. Prior to the introduction of Bt cotton, it is estimated that 55% of total pesticides used in agriculture was consumed by cotton crop alone (values at $350 million) to control bollworm and sucking pests attack. However Bt cotton technology is found to be more reliable in managing bollworm problem in cotton crop.
