05. Efficacy of Miayalin G2 Suckericide on the yield of FCV tobacco
Main Article Content
Abstract
Topping followed by desuckering are very important operations for improving leaf yield of tobacco, by larger size and weight of leaves. Although topping may be done once, removal of secondary suckers takes place several times during the season. So application of suckericide within health limit concentrations to suppress the growth of suckers are very important. A field experiment was conducted at Pakistan Tobacco Board Research Station Khan GarhiMardan, during 2011-2012 to study the efficacy of Miayaling2 to find out its optimum concentration for suckers control and enhancing leaf yield of FCV tobacco. The treatment composed of control (no suckering) with three levels of Miayaling2 (900 ml ha-1, 1000 ml ha-1and 1200 ml ha-1) arranged in RCB design with three replication. After 20 days of suckericide application, greater number of suckers plant-1 (3) was recorded from control plots while lower (2) in plots treated with 1200 ml ha-1. Similarly higher leaf area (729.3 cm2) and cured leaf yield (2560 kg ha-1) was recorded in 1200 ml ha-1 treated plots while lower leaf area (657.3 cm2) and cured leaf yield (2350 kg ha-1) was obtained from control plots. The present study indicated that application of suckericide with 1200 ml ha-1 level suppress suckers well than and gave higher leaf yield of FCV tobacco.
