The study was conducted at the experimental field of Horticulture Research Centre, BARI, Gazipur during Rabi seasons in three years (2012 to 2015) to investigate the response of broccoli (cv. Premium crop) under different irrigation regimes. The experiment was conducted in RCBD with five replications. There were four treatments: I1=Irrigation up to FC at 5 days interval after plant establishment (PE), I2= Irrigation up to FC at 10 days interval after PE, I3 = Irrigation up to FC at 15 days interval after PE and I4= Irrigation up to FC at 20 days interval after PE. A significant response of broccoli to different irrigation levels was observed. Among the different treatments, I2 (irrigation at 10 days interval) was significantly better yielding (19.98 t/ha, 20.63 t/ha and 16.24 t/ha in 1st, 2nd and 3rd year, respectively). The lowest yields were observed from the treatment I4 each in all 3 years. The highest seasonal water (382.30 mm, 296.58 mm and 305.00 mm in 1st, 2nd  and 3rd year) were used in treatment I1 and the lowest (204.60 mm, 185.66 mm and 179.77mm in the 1st, 2nd  and 3rd year) were used in treatment I4, I3 and I3, respectively. The results suggest that irrigation at 10 days interval (I2) might be optimum irrigation schedule for broccoli production on the basis of gross return. But in respect of economic profitability, the highest marginal rate of return is obtained from treatment I3.The Agriculturists 2016; 14(1) 98-106

Field experiments were carried out at Regional Agricultural Research Station (RARS), Ishurdi, Pabna during the rabi season of 2005-06 and 2006-07 to find out the effectiveness of Rhizobium strains for achieving higher yield of lentil, the variety BARI Masur–4. There were six treatments that were Rhizobium strains- BARI RLc-104, BARI RLc-105, BARI RLc-106, BARI RLc–107, mixed culture of the four strains, and control (no Rhizobium). The experiment was designed in randomized complete block having 4 replications of each treatment.The rhizobial inocula were peat based and used @ 1.5 kg/ha. A basal dose of P @ 22 kg/ha, K @ 42 kg/ha, S @ 20 kg/ha, and @ 5 kg Zn/ha was used for all treatments. The highest nodule number (11.7/plant in 2006 and 10.3/plant in 2007) and dry nodule weight (10.53 mg/plant in 2006 and 9.58 mg/plant in 2007) were found with mixed culture. Mixed culture produced the highest seed yield in 2006 (1.36 t/ha, 37.4% higher over uninoculated control) and in 2007, BARI RLc-104 recorded the highest seed yield (1.23 t/ha, 60.3% higher over uninoculated control). However, all the strains including mixed culture had similar seed yields over the years. DOI: http://dx.doi.org/10.3329/bjar.v39i1.20147 Bangladesh J. Agril. Res. 39(1): 105-112, March 2014

The experiment was conducted at the research field of the Agronomy Division, Bangladesh Agricultural Research Institute (BARI), Gazipur and Regional Agricultural Research Stations (RARS), Burirhat during two successive rabi seasons  of 2015 and 17 to find out the relation between different development events of garden pea  (Pisum sativum L.) and the sowing time based temperature, and  also to minimize the yield reduction by adopting appropriate management practices.  The treatments comprised with three sowing dates (30 November, 15 December and 30 December) and three management practices (low, medium and high). Under high management, Nov. 30 sowing took maximum days (64 days in 2015-16 and 58 days in 2016-17 at  Joydebpur and 58 days in 2015-16 and 57 days in 2016-17 at RARS, Burirhat) to reach harvesting maturity. The results indicated that the number of days required for attaining different phenological stages decreased with delay of sowing. Late sowing took minimum time from flowering to fresh pod maturity (51 days and 49 days in two years at Joydebpur, and 49 days and 46 days in two years at Burirhat) due to increase in minimum temperature. The results revealed that the highest pod yield (14.77 t ha-1in 2015-16 and 13.09 t ha-1in 2016-17 at Joydebpur and 9.63 tha-1 in 2015-16 and 10.33 t ha-1in 2016-17 at Burirhat) was recorded from 30 November sowing with high management practices which was followed by 15 December with  the same management. Yield reduction in late sowing was reduced to some extent by high management practices. The two year results revealed that 30 November sowing with high management practices (extra 20% recommended  fertilizer dose, HRC + two irrigation at pre flowering and pod development stage + seed treatment +  one weeding at 21 DAE) showed better pod yield than other combinations.
