NISHAT TASLIM The field experiment was conducted at the research field of Department of Agronomy, Hajee Mohammad Danesh Science and Technology University, Dinajpur-5200, during the period from July 2023 to December 2023 in aman season to observe the growth and yield performance of aromatic rice in response to variety and level of Boron. The experiment comprised of two factors viz. factor A: Varieties; V1 = katarivog, V2 = Kalizira and V3 = Tulsimala; factor B: Levels of Boron; T1 = No application of boron, T2 = 100 ppm, T3 = 200 ppm, T4 = 300 ppm. The experiment was laid out in a RCBD design with three replications. Different variety had significant influenced on growth, yield and yield contributing parameters. The highest plant height (59.92, 108.07, 137.98 and 152.77 cm at 30, 60, 90 DAT and at harvest respectively) was achieved from the variety V2 (Kalizira). The highest number of tillers hill-1 (12.73, 22.75, 28.07 and 22.72 at 30, 60, 90 DAT and at harvest respectively) was obtained from the variety V2 (Kalizira). The highest number of panicles hill-1 (29.98), panicles length (26.83cm), effective tiller (22.45), was found from V2 (Kalizira). On the Other hand different rates of boron foliar application had also significant influenced on growth, yield and yield contributing parameters. The highest number of tillers hill-1 (14.84, 24.82, 29.78 and 22.55 at 30, 60, 90 DAT and at harvest respectively), panicle length (25.602 cm), number of effective tillers hill-1 (21.43), was obtained from T 3 treatment. Again the highest 1000-grains weight (11.87 g), grain yield (3.32 t ha-1), straw yield (7.56 t ha-1), biological yield (10.88 t ha-1), harvest index (31.26%) was obtained from T3 treatment. Interaction effect of variety and splitting different rates of boron as foliar application had also significant influenced on growth, yield and yield contributing characters of aromatic rice. The highest grain yield (3.430 t ha-1) from V2T3 and the lowest yield (2.14 t ha-1) obtained from V3T1 from the combined effect of varieties and Different levels of B doses. The results indicate that the best performing kalizira aromatic rice variety in Bangladesh would benefit by applying 200 ppm of boron.

The experiment consisted of two factors where one factor was varieties namely V1 (BARI Sarisha-15), V2 (BARI Sarisha-17) and V3 (BARI Sarisha-19) and another four treatments e.g. T1 = 0 ppm (control), T2 = 25 ppm GA3, T3 = 50 ppm GA3 and T4 = 75 ppm GA3. The experiment was designed in Randomized Complete Block Design (RCBD) with three replications. Parameters like plant height (cm), number of branches plant 1 (no.), number of leaves plant-1 (no.), leaf area (cm2), number of siliqua plant-1 (no.), fresh weight of seed-1(g), dry weight of seed-1(g), total fresh and dry weight plant-1 (g), thousand seed weight (g), seed yield (t ha-1), biological yield (t ha-1), stover yield (t ha-1), and harvest index (%). The highest thousand-seed weight 28.66 g observed was V1( BARI Sarisha -15) ,Seed yield showed better result with the variety V2 (BARI Sarisha -17) 1.18 t ha-1, Biological yield showed better performance with the variety V1 (BARI Sarisha-15) 12.45 t ha-1 and the maximum harvest index were recorded in V2 (BARI Sarisha-17) with 45.16 %.T3 (50 ppm GA3) showed best performance than the other treatment in most of the parameters specially in 1000 seed weight ( 37.72 g) , seed yield (1.26 t ha-1), biological yield (4.43 t ha-1) and harvest index (45.23%). Interaction result showed that BARI Sarisha-17 along with T3 (50 ppm GA3) possed the highest seed yield 1.3 t ha-1. But the lowest result of 1000-seed weight (23.85 g), biological yield (2.42 t ha1), seed yield (0.69 t ha-1) and harvest index (28.15%) were obtained from the control. So, it could be concluded that GA3 at 50 ppm showed better performance than all other treatment.

MOLY, MAHMUDA The experiment was conducted in the Agronomy Shade House, Department of Agronomy, Hajee Mohammad Danesh Science and Technology University, Dinajpur 5200, Bangladesh from May 2024 to July 2024. The present study was conducted to evaluate the effect of foliar application of Selenium (Se) nanoparticles on mitigating drought stress and improving growth, yield, and physiological parameters of sesame (Sesamum indicum L.,) variety BINA Til-3. The experiment was laid out in a Completely Randomized Design (CRD) with eight Se nanoparticle treatments namely (T0 = Control, T1 = 5 ppm, T2 = 10 ppm, T3 =15 ppm,T4 = 20 ppm, T5 = 25 ppm, T6= 30 ppm, T7= 35 ppm).The experiment consisted with three replications i.e., 24 pots during the Kharif season from May 2024 to July 2024.Results demonstrated that moderate Se dose T5 = 25 ppm significantly improved number of leaves, leaf area, chlorophyll content, and photosynthetic pigments, while enhancing cell membrane stability and water retention under drought stress. Treatment T5 exhibited the highest chlorophyll content (58.03 SPAD at 28 DAS) and optimal leaf morphology and achieved the maximum seed yield (1.22 t/ha), a 103% increase over the control. Higher Se concentrations (≥30 ppm) showed diminishing returns or potential toxicity, as evidenced by reduced growth and yield. Physiological analyses revealed that Se application enhanced antioxidant activity, proline accumulation and nutrient uptake (N, K) contributing to improved drought tolerance. The study concluded that foliar application of Se NPs at T5is optimal for enhancing sesame productivity under drought conditions, offering a sustainable strategy to combat water scarcity in sesame cultivation. These findings align with global research on nanotechnology in agriculture, highlighting Se NPs as a promising tool for stress mitigation and yield improvement in oilseed crops.
