Yield and yield attributes of chickpea as affected by different insecticides used in storage

Abstract

Field experiments were carried out in Pulses Research Centre Experimental Field, Bangladesh Agricultural Research Institute, Joydebpur, Gazipur, Bangladesh during November to March 2004-05 and 2005-06 to study the effects of different insecticides on yield and yield attributes of chickpea. Seeds were preserved with different fungicides and stored them in earthen pots. The seeds were divided into four parts including a part considered as the control. For the insecticide treatment, fungicides such as Sevin, Mipsin and Asataf were used at the rate 1g/kg of chickpea seeds. Chickpea seeds were stored until next planting time and seed quality was observed during storage period. Significant effect of the fungicides was observed on pods/plant both in 2004-05 and 2005-06, seeds/pod in 2004-05 and seed yield both in 2004-05 and 2005-06. The highest values for almost of all these characters were observed when the seeds were preserved with Sevin. Sevin was at par with Mipsin for seed yield of chickpea in 2005-06 only. Among three insecticides, Asataf showed less effect. Sevin treated seeds gave the highest plant height, pods/plant (48.3 in 2004-05 and 48.6 in 2005-06), seeds/pod (1.77 in 2004-05 and 1.81 in 2005-06), 1000- seed weight (120 g in 2004-05 and 121 g in 2005-06) and seed yield (1304 kg/ha in 2004-05 and 1251 kg/ha in 2005-06) which were somewhat identical to Mipsin and Asataf but significantly higher over control.
