Lentil in Bangladesh is generally grown under residual soil moisture after cessation of monsoon rain. During planting time of lentil,most of the farmer's field show lack of sufficient soil moisture required for germination,which leads to poor plant establishment and ultimately low yield. To overcome this situation,seed priming has been recommended as a key management technology to ensure proper germination of seeds and optimum plant population. In this context,field experiments were carried out at the research farm of the Pulses Research Centre,Ishurdi,Pabna,Bangladesh,during 2001-2002 and 2002-2003 cropping seasons. Two varieties ,BARI Masur-2 & BARI Masur-4 were used under six treatments consisting of different priming periods. The results showed that BARI Masur-2 responded better with seed priming than BARI Masur-4 variety and,8 and 10 hours seed priming gave the highest yield advantage irrespective of variety. Therefore,it has been recommended that farmers do 8-10 seed priming before seeding lentil to achieve higher yields.

To find out the effect of seed priming on yield and yield components of lentil
A field experiment was conducted at the calcareous Grey Flood Plain soils of the Pulses Research Centre, Ishurdi, Pabna,Bangladesh under rainfed condition during rabi season of 2001-2002 and2002-2003. The soil of this experimental plots was sandy loam having pH 7.5, containing 1.2% organic matter, 17 ppm N, 26 ppm P and 300 ppm K. Two varieties of lentil i.e. BARI Masur-2 (V1) & BARI Masur-4 (V2) were placed in the main-plot and six seed priming levels i.e. non-primed (T1), 2 hours (T2), 4 hours (T3), 6 hours (T4), 8 hours (T5) and 10 hours (T6) were placed in the sub-plot. Seeds were primed i.e. seeds soaked in water as per treatment, surface drying them and then sowing within the same day. The experiment was laid out in a split-plot design with three replications. Unit plot size was 5m x 4m. The date of sowing were 6 and 8 November, 2001-2002 & 2002-2003,respectively. Seeds were sown in lines with 25cm apart. Soils were collected before sowing from different plots and then dried in a oven and soil moisture percent was determined through gravimetric method. Fertilizers were used @ 20-40-20 kg/ha N-P205-K20 at final land preparation as urea, triple super phosphate and murate of potash respectively and seed rate was 30 kg/ha. Days to germination and plant population/Liner Meter(LM) were recorded at emergence. Intercultural operations were done as and when required. The crop was harvested on 1 and 3 March, 2001-2002 & 2002-2003,respectively. Data on yield and yield contributing characters like plant height (cm), number of branches/plant, number of pods/plant, number of seeds/pod, 1000 seeds weight(g) and grain yield (kg/ha) were recorded. The data were statistically analyzed and mean values were compared by Duncan's Multiple Range Test. The crop received 20.2mm and 41.5mm rainfall during crop season in 2001-2002 & 2002-2003,respectively.
