The experiment was carried out at Agronomy Research field of Bangladesh Agricultural Research Institute (BARI), Joydebpur, Gazipur and Regional Agricultural Research Station, Hathazari, Chittagong to find out optimum sowing date of sunflower during rabi season 2012-13. The sunflower var. BARI Surjomukhi-2 was used. Five sowing dates; 10 November, 20 November, 30 November, 10 December and 20 December were tested. It was revealed that yield and yield attributes of sunflower were significantly influenced by sowing dates. The maximum plant height (172.13 cm), head diameter (18.33), weight of seed / per head (66 g), 1000- seed weight (68 g) and yield (2.5 t ha?1) were obtained from 20 November sowing. The lowest yield (1.83 t ha?1) was obtained from 20 December sowing. The 20 November sowing received the higher duration for maturity (127 days), first flowering (57 days) and seed formation (20 days) while 20 December sowing showed shorter duration for maturity, first flowering and seed formation of 119, 54 and 14 days respectively. It was concluded that the 20 November sowing would be the optimum time of sowing for achieving maximum yield of sunflower.Bangladesh Agron. J. 2015, 18(1): 1-5

The experiment was conducted at the research field of the Agronomy Division, Bangladesh Agricultural Research Institute (BARI), Bangladesh during rabi season of 2017-2018 to evaluate the flowering behavior and pod yield of French bean. Three varieties namely BARI Jharsheem-1, BARI Jharsheem-2 and BARI Jharsheem-3 were sown on 30 November, 15 December and 30 December, respectively for getting temperature variation. Sowing dates based on temperature variation, significantly affect the flowering behaviour and pod yield of French bean varieties. Developmental events were badly affected when sown on 30 December. Crop accumulated lower GDD for different development events when sown late. Flowering duration of 30 November sowing were longer due to  prevailing low temperatures (Min.10.3-11.4 °C and Max 23.7-24.5 °C) (Table 2). On the contrary, minimum flowering duration was recorded in 30 December sown crop (11-17 days). Minimum duration might be due to prevailing high temperature (Min.14.9-15.3 °C and Max 27.6-28.8 °C) that shorten the flowering duration of all French bean varieties. Pod yield of all the varieties were more at November sowing and decreased towards late sowing.  November 30 sowing performed better in relation to yield components and yield which was very close to 15 December sowing. BARI Jharsheem-1 produced the highest pod yield (16.77t ha-1) in 30 November sowing. French bean had been sown on November to December showed the greater variability in respect of flowering, flowering duration and the number of pods. The results revealed that November would be the optimum sowing date (15 Nov.-30 Nov.) for maximum pod yield of french bean var. BARI Jharsheem-1 Bangladesh Agron. J. 2018, 21(2): 25-32

A study on comparative productive efficiency and feasibility of lentil varieties both at relay and minimum tillage were conducted at the Regional Agricultural Research Station, BARI, Ishurdi, Pabna, Bangladesh during the Rabi season of 2007-08 and 2008-09. Three lentil varieties viz. BARI Masur-2, BARI Masur-3 and BARI Masur-4 and two sowing methods viz. relay sowing and furrow sowing (Minimum tillage) were compared. The highest seed yield (1.59 t/ha) was obtained from BARI Masur-4 because of highest number of pods/plant and plant population/m2 while lowest from BARI Masur-2 (1.39 t/ha). The sowing methods had significant effect on the seed yield of lentil. Crops sown in furrows produced higher seed yield (1.60 t/ha) than that of crops in relay sowing. The interaction effect between varieties and sowing methods also had significant effect on the seed yield and yield attributes. The lentil variety BARI Masur-4 when grown in furrows gave the highest seed yield (1.70 t/ha). Though seed yield and gross return were highest in furrow sowing but highest benefit cost ratio (4.67) was found in relay sowing method.Bangladesh J. Agril. Res. 40(2): 271-278 June 2015

The experiment was carried out at the research field of Agricultural Research Station, Rajbari, Dinajpur (Latitude: 25.63544, Longitude: 88.65144) during rabi season of 2016-2017 and 2017-18 under AEZ-1 to find out the suitable crop combination for higher productivity and economic return. Five different treatments were employed in the study viz. T1= Sole maize (60cm x×20cm), T2= Maize planting (75cm×x 25cm) + 1 row cabbage (50cm×50cm) T3= Maize paired row (150cm/37.5cm x 25cm) + 2 rows cabbage (50cm x×50cm) T4=Maize planting (60cm x×20cm )+1 row cabbage (60cm x×50cm), T5= Maize paired row (120cm/30cm× x 20cm) + 2 rows cabbage (60cm x 50cm) were evaluated. Maize grain yield in intercropped combination varied from 6.60-9.23 t ha-1. But the highest maize yield was recorded in Maize planting (60cm x 20cm) + 1 row cabbage (60cm x 50cm) followed by that in maize paired row (150/37.5cm × 25cm) +2 rows cabbage (50cm x×50cm), while the highest cabbage yield was recorded in maize planting (60cm x 20cm) + 1 row cabbage(60cm x 50cm) between maize. The highest maize equivalent yield was also obtained in maize planting (60cm x 20cm) + 1 row cabbage (60cm x 50cm) followed by that in maize paired row (150/37.5cm x 25cm) + 2 rows cabbage (50cm x 50cm). The highest gross return, gross margin and BCR were obtained in maize planting (60cm × 20cm) + 1 row cabbage (60cm x 50cm) followed by that in maize paired row (150/37.5cm x 25cm) +2 rows cabbage(50cm x 50cm) and the lowest in sole sowing of maize. The overall results indicated that among the intercrop combinations maize planting (60cm x 20cm) + 1 row cabbage (60cm x 50cm) and maize paired row (150/37.5cm x 25cm) +2 rows cabbage (50cm x 50cm) were found suitable for total productivity and economic return of the system.

An experiment was conducted at Agronomy Research Field of Bangladesh Agricultural Research Institute, Gazipur for five consecutive years (2014-2015 to 2018-2019) to establish a functional relationship between grain yield and spikes/m2 of wheat at late sown condition. Variation of spikes/m2 was created by five seed rates (90, 120, 150, 180  and 210 kg/ha). Pooled average value of spikes / m2 was observed the highest (479-506) in 180-210 kg seed /ha. From the structural treatment, the highest grain yield (pooled average of 3876-4153 kg/ha ranged 3295-5028 kg/ha) of wheat was produced in the seed rate of 150-180 kg/ha. The estimated optimum seed rate was found 162.29 kg/ha with the estimated grain yield 3989 kg/ha of wheat at late sown condition through the developed function model of Y=485.91+43.17X-0.133X2 (R2=0.87). Again, the estimate optimum spikes/m2 was noticed 423 when the estimated grain yield of wheat was 4135 kg/ha at late sown condition through the developed functional model of Y=-2837+32.98X-0.039X2 (R2=0.83). The grain yield would be increased about 13% as compared to recommended seed rate (120 kg/ha) of wheat. Spikes / m2 had significant positive correlation with seed rate (r=0.79 at p=0.05) of wheat. Relationship between observed grain yield and predicted grain yield (when relationship between spikes/m2 and grain yield) showed a good consistency (Y=1.0006X, R2=0.94 and r = 0.97 at p<0.01). From the results of the study it is concluded that 162 kg/ha of seed rate and 423 spikes / m2 would be optimum for maximum yield) 4135 kg/ha) of wheat at late sown condition. Bangladesh Agron.

This experiment was conducted in Homs Agricultural Research Station, Homs, Syria during 2007/2008 and 2008/2009 seasons to study the effect of sowing date and plant density on bolting for four sugar beet varieties, tow are monogerm varieties i.e. Parade and Etna, while the other are multigerm varieties i.e. Nadir and Mammoth. Three sowing dates were applied, began from 15/9 to 15/10, the interval between the sowing dates was 15 days. Three plant densities were executed (133 000, 100 000 and 80 000 plantha-1). Split plot design was used with three replicates. The combined analysis exhibited the significant effect of varieties (V), sowing dates (S), and plant densities (D) on all types of bolting (Early, medium, late and total). Least significant test (L.S.D 0.05) clarified that early autumn sowing (15/9 and 1/10) increased total bolting percent 74.86 and 44.88 % respectively, as compared with date (15/10) 15.57% (control). The plant density (133 000 plant ha-1) decreased total bolting percent 43.56% as compared with the other plant densities (80 000 and 100 000 plant ha-1) 46.35 and 45.40% respectively. The results showed that the monogerm varieties were superior and more resistant to bolting as compared with the multigerm ones.
