Effect of Sowing Dates on Sucking Insect Pests in Black Gram at Yezin

Experiments were conducted at Yezin Agricultural University Farm during May 2011 to February 2012 to examine the effect of sowing dates on sucking insect pests in black gram (Yezin-4). A Randomized Complete Block design (RCB) was used with five treatments (different sowing dates) and four replications. Treatments were five sowing dates (T1 – 14 May T2 – 21 May T3 – 28 May T4 – 4 June T5 – 11 June in 2011 wet season) and (T1 – 29 October T2 – 5 November T3 – 12 November T4 – 19 November T5 – 26 November in 2011 dry season).
