The use of pre-emergence herbicides was found to be the most effective weeds control measure under the DSR system. Although several herbicides are now available in market, the selection of right herbicides with a time of application is crucial for effective control of weeds as well as to reduce the phyto toxicity of crops. A field study in a split-plot design with three replications was conducted&nbsp; to evaluate the effect of application time of soil applied herbicides (viz., 3 times - before crop sowing, after crop sowing but before the first irrigation, and after sowing and first irrigation) and four weeding regimes (viz., weed free, partial-weedy, herbicide oxadiargyl 80 g ai ha<sup>-1</sup>, and pendimethalin 1000 g ai ha<sup>-1</sup>) on weed control efficacy, crop performance as well as phytotoxicity of applied herbicides under DSR system. Rice plant stand establishment was highly influenced by application time of herbicides and weeding regimes. Application of pendimethalin at 1000 g ai ha<sup>-1 </sup>significantly reduced the density of rice plant, more so as sowing was advanced. Compared with the non-treated (partial-weedy) treatment (190 to 195 rice plants m<sup>-2</sup>), pendimethalin application before sowing, after sowing but before irrigation, and after sowing and irrigation reduced rice plant density by 48, 25 and 12%, respectively. While no significant difference was observed on plant density due to the application of oxadiargyl 80 g ai ha<sup>-1</sup>, regardless of application time. In case of weed control efficacy for individual herbicides, pendimethalin effectively controlled weeds even spraying before sowing and irrigation; but comparatively less effective than spraying after irrigation. In controlling weeds, oxadiargyl was only effective when spraying after sowing and irrigation, but not before irrigation. Grain yield was significantly increased as the time of herbicide was delayed from before sowing (2.2-2.4 t ha<sup>-1</sup>), after sowing but before irrigation (2.5-2.6 t ha<sup>-1</sup>), and after sowing and irrigation (4.0-4.1 tha<sup>-1</sup>). The results suggest that pre-emergence herbicides should be applied after sowing and irrigation for controlling weeds effectively and also reduce crop toxicity under the DSR system.</p> <p><em>Bangladesh Agron.

Green manuring crops were incorporated after in situ cultivation and results showed that, the biomass incorporation increased the N production in soil. The biomass from Sesbania rostrata, Sesbania aculeata and Crotalaria juncea gave the higher dry matter and nutrient status. Incorporation of Sesbania rostrata and Sesbania aculeata added more organic matter and nitrogen to the soil after green manure incorporation than the prior soil. However, the improved soil quality was recorded with S. rostrata and S. aculeata followed by C. juncea and V. unguiculata incorporation as compared to control (no green manure) and other green manuring crops. The nutrient balance of soil after incorporation of different green manuring crops specially S. rostrata, S. aculeata and C. juncea showed positive balance of nutrients than other green manures.</p> <p><em>Bangladesh Agron.

Sowing dates induced temperature variability showed remarkable changes in pheonlogy, leaf area, leaf chlorophyll content, dry matter production and seed yield. Although December 20 sown crop received lower temperatures (minimum 9.8 to 13.2 and maximum 22.6 to 27<sup>o</sup>C) than November 20 sown crop (minimum 14.8 to 16.4 and maximum 21 to 27.2<sup>o</sup>C) at flowering but reverse was found at grain development stage. Grain development stage of November 20sown crop received lower temperatures (minimum 8.2 to 13.2 and maximum 24.1 to 27 <sup>o</sup>C) while December 20 sown crop received higher temperatures at grain development stage (minimum 8.2 to 18 and maximum 22.6 to 32.5<sup>o</sup>C).As a result December 20 sown crop matured earlier (6 to 9 days) than November 20 sown crop. Leaf area/plant was higher in December 20 sown crops compared to November 20 sown but total dry matter production was more or less same in both the sowing dates. Leaf chlorophyll content did not show any remarkable variation due to variation in sowing dates. However, antioxidant activity like Catalyse (CAT), Peroxidase (POD) Ascorbate peroxidase (APX) and Malondial dehyde (MDA) were found higher in December 20 sown crops than that of November 20sown. Higher activity of APX, POD and CAT with lower activity of MDA indicates comparatively high temperature tolerant genotype. Among the genotypes APX, POD and CAT activity were found higher with lower activity of MDA in BJDH-11 and BJDH-20 and these genotypes also gave higher yield than others. On the basis of growth parameters, antioxidant activity and seed yield of genotype BJDH-11 and BJDH-20 could be select as terminal high temperature tolerance genotypes.</p> <p><em>Bangladesh Agron.

BRRI dhan50). The experiment consisted of three water managements viz. conventional flood irrigation, AWD (Alternate Wetting and Drying) and SRI (System of Rice Intensification); two nutrient managements viz. recommended dose of inorganic fertilizers (Urea, TSP, MoP, Gypsum, ZnSO<sub>4 </sub>@ 250, 120, 120, 100, 10 Kg ha<sup>-1</sup>, respectively) and 25% less than recommended dose of inorganic fertilizer + poultry manure @ 2.5 t ha<sup>-1</sup>; and three weed managements viz. weedy check (control), two hand weeding at 20 and 40 DAT, and pre-emergence herbicide (Rifit 33EC) followed by post emergence herbicide (Fast klin 10WP) application. The highest number of effective tillers hill<sup>-1</sup>, grains panicle<sup>-1</sup>,grain yield and protein (%) in grain were obtained in SRI water management which was followed by AWD and conventional flood irrigation. Between the two nutrient management practices, application of 25% less than recommended dose of inorganic fertilizer + poultry manure @ 2.5 t ha<sup>-1 </sup>produced higher number of effective tillers hill<sup>-1</sup>,grains panicle<sup>-1</sup>,1000-grain weight, grain yield and protein (%) in grain than in organic fertilizer. Among the weed management practices, application of pre-emergence herbicide (Rifit 33EC) followed by post-emergence herbicide (Fast Klin 10WP) produced the highest number of effective tillers hill<sup>-1</sup>,grains panicle<sup>-1</sup>,1000-grain weight, grain yield and protein (%) in grain followed by two weedings at 20 and 40 DAT while the lowest grain yield was obtained in weedy check. The highest number of effective tillers hill<sup>-1,</sup>grains panicle<sup>-1, </sup>grain yield and protein (%) in grain was found in SRI water management combined with 25% less than recommended dose of inorganic fertilizer + poultry manure @ 2.5 t ha<sup>-1</sup> and application of pre-emergence herbicide followed by post-emergence herbicide. So, it may be concluded that, to get the highest grain yield in aromatic Boro rice, SRI method along with application of 25% less than recommended dose of inorganic fertilizer + poultry manure @ 2.5 t ha<sup>-1</sup> and applying pre-emergence herbicide (Rifit 33EC) followed by post emergence herbicide (Fast Klin 10WP) could&nbsp; be recommended.</p> <p><em>Bangladesh Agron.

Variation of spikes/m<sup>2</sup> was created by five seed rates (90, 120, 150, 180&nbsp; and 210 kg/ha). Pooled average value of spikes / m<sup>2 </sup>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-0.133X<sup>2</sup> (R<sup>2</sup>=0.87). Again, the estimate optimum spikes/m<sup>2</sup> 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-0.039X<sup>2</sup> (R<sup>2</sup>=0.83). The grain yield would be increased about 13% as compared to recommended seed rate (120 kg/ha) of wheat. Spikes / m<sup>2 </sup>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/m<sup>2</sup> and grain yield) showed a good consistency (Y=1.0006X, R<sup>2</sup>=0.94 and r = 0.97 at p&lt;0.01). From the results of the study it is concluded that 162 kg/ha of seed rate and 423 spikes / m<sup>2</sup> would be optimum for maximum yield) 4135 kg/ha) of wheat at late sown condition.</p> <p><em>Bangladesh Agron.

Five different treatments were employed in the study viz. T<sub>1</sub>= Sole maize (60cm x×20cm), T<sub>2</sub>= Maize planting (75cm×x 25cm) + 1 row cabbage (50cm×50cm) T<sub>3</sub>= Maize paired row (150cm/37.5cm x 25cm) + 2 rows cabbage (50cm x×50cm) T<sub>4</sub>=Maize planting (60cm x×20cm )+1 row cabbage (60cm x×50cm), T<sub>5</sub>= 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<sup>-1</sup>. 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.</p> <p><em>Bangladesh Agron.

Seeds were collected from siliqua of different rapeseed-mustard varieties and harvesting was made at different maturity stages based on their external color i.e., Green, pale yellow, Golden yellow and full maturity stage of siliqua. After harvesting of siliqua as per external color seeds were dried naturally about 48 hours and were packed in polythene and stored at laboratory environment for next season uses. Under laboratory condition seeds were evaluated in terms of moisture and germination percentage, speed of germination, root and shoot length, vigor index etc. Moisture content was found significantly at elevated level in respect of mustard varieties of BARI Sarisha-14 (V<sub>2</sub>), BARI Sarisha-6 (V<sub>3</sub>) and Tori-7 (V<sub>4</sub>).&nbsp; The variety Tori-7 and BARI Sarisha-14 showed&nbsp; the highest vigor index-II &amp; vigor index-I, respectively. Among the harvesting stages, most of the parameters showed the highest standards in seeds harvesting at full maturity of siliqua stage (H<sub>4</sub>) followed by the golden yellow siliqua stage (H<sub>3</sub>) and pale yellow siliqua stages seeds (H<sub>2</sub>).Irrespective of rapeseed-mustard varieties seed collected from golden yellow and pale yellow siliqua stages could&nbsp; be stored up to twelve month for next season without significant loss in terms of germination percentage and vigor followed by full maturity stages of siliqua harvested seeds (H<sub>4</sub>).</p> <p><em>Bangladesh Agron.
