The experiment was conducted to study the response of lentil to irrigation levels and different methods of boron application in relation to yield and yield contributing characters. Three levels of irrigation viz., I0: control (No irrigation), I1: one irrigation at 25 days after sowing (DAS), I2: two irrigations at 25 DAS and 40 DAS, and four levels of Boron viz., B0: control (No boron), B1: 80% recommended dose (RD) as basal + rest 20% as a foliar spray (FS) at pre-flowering (PF), B2: 60% RD as basal + rest 40% as FS at PF, B3: 40% RD as basal + rest 60% as FS at PF as treatment variables. It was found that the highest number of pods plant-1, number of seeds pod-1, 1000-seed weight, pod length, seed yield and stover yield was obtained with two irrigations. In contrast, B3 had a significant effect on the yield contributing characters of lentil. Results also revealed that numerically more seed yield (638.23 kg ha-1) was recorded in I2B3. Similar trend was found in case of stover yield (751.26 kg ha-1) and biological yield (1389.4 kg ha-1) from I2B3 combinations. These results suggested that combined application of irrigation at 25 and 40 DAS and boron at 40% RD as basal + rest 60% as FS at PF significantly enhanced the crop yields of lentil.

The field experiment was conducted at Agronomy Research Field, Joydebpur and RARS, Burirhat, Rangpur, BARI during Rabi season of 2018-2019 and 2019-2020 to find out suitable combination of sorghum and gardenpea intercropping for higher productivity and monetary advantage. Treatments included in the experiment were: T1 = Sorghum normal row (SNR) + 1 row gardenpea (GP), T2 = SNR + 2 rows GP, T3 = Sorghum paired row (SPR) + 2 rows GP, T4 = SPR + 3 rows GP, T5 = SPR + 4 rows GP, T6 = Sole sorghum (60 cm ´ 10 cm) and T7 = Sole GP (30 cm ´ 10 cm). Light availability on gardenpea decreased with the increase of shade produced by sorghum canopy over the time up to 60 DAS. The lowest light availability on gardenpea was observed in T2 treatment and the highest was observed in sole gardenpea (T7) followed by T3 treatment in both the years. The maximum grain yield of sorghum was observed in T6 and it was decreased (6-10% in 2018-2019 and 1-12% in 2019-2020) at Joydebpur and (5-11% in 2018-2019 and 6-14% in 2019-2020) at Burirhat. The highest sorghum equivalent yield (SEY) of 10.93 t ha-1 in 2018-2019 and 12.02 t ha-1 in 2019-2020 at Joydebpur and 12.06 t ha-1 in 2018-2019 and 11.77 t ha-1 in 2019-2020 at Burirhat and also the highest land equivalent ratio (LER) of 1.77 in 2018-2019 and 1.93 in 2019-2020 at Joydebpur and 1.79 in 2018-2019 and 1.81 in 2019-2020 at Burirhatwere observed in T5 treatment.

An experiment was conducted at coastal charlandof OFRD, BARI, Noakhali;MLT site, Amtoli,Bargunaand ARS,Benarpota, Satkhira during Rabi season of 2018-19to evaluate the effect of integrated nutrient management on growth,yield and economic performance of sunflower. Six treatment combinations viz. T1= Soil test based fertilizer dose for HYG, T2 = IPNS with 5 tha-1cowdung, T3= IPNS with 5 tha-1 compost, T4= IPNS with 1.5 t ha- 1vermicompost, T5= Farmers’ practice and T6= Absolute control were tested. The experiment was laid out in a randomized complete block design with 3 replications and BARI Sunflower-2 was used as test crop.The IPNS treatment combinations are significantly differentfrom rest of the treatments in terms of yield and economic return. Application of treatment IPNS with 1.5 tha-1vermicompost significantly increased all of the parameters such as the plant height, head diameter, number of seed per head,1000 seed weight, seed yield and stover yield. The significantly highest seed yield (2.19, 2.23 and 2.06 t ha-1 at Noakhali, Bargunaand Satkhira, respectively) was recorded in IPNS with 1.5 tha-1vermicompost treated plot (T4) while the lowest seed yield (1.05, 1.10 and 1.02 t ha-1 at Noakhali, Barguna and Satkhira, respectively) was observed in absolute control treatment (T6). Salinity level increased at slower rate in T2, T3 and T4, treatments where IPNS based nutrient management packages were imposed.During the crop growing period soil salinity ranged from 0.62 to 9.72dS m-1, 0.58 to 9.23dS m-1, 0.73 to 9.86dS m-1 at Noakhali, Barguna and Satkhira, respectively from emergence to maturity stages of the crop. The highest net return (50790 Tk. ha-1, 52765 Tk. ha-1 and 43940 Tk. ha-1 at Noakhali, Barguna and Satkhira, respectively) as well as BCR (1.75, 1.78 and 1.67 atNoakhali, Barguna and Satkhira, respectively) were obtained from T4 treatment (IPNS with 1.5 tha-1vermicompost) whereas the lowest net return (14900 Tk. ha-1 ,15175 Tk. ha-1 and 11570 Tk. ha-1 at Noakhali, Barguna and Satkhira, respectively) and BCR (1.40, 1.33 and 1.26at Noakhali, Barguna and Satkhira, respectively) were obtained from control (T6) treatment. The overall results indicated that IPNS with 1.5 tha-1 vermicompostis more effective than other fertilizer management packages in respect of yield as well as economic return for sunflower cultivation in the coastal charland of Bangladesh.

A field experiment was conducted for evaluating the effect of irrigation and boron splitting as foliar spray on growth and yield of lentil at the Research Field of the Department of Agronomy, Sher-e-Bangla Agricultural University, Dhaka from November, 2018 to March, 2019.Three levels of irrigation viz., I0: control, I1: one irrigation at 25 days after sowing (DAS), I2: two irrigations at 25 DAS and 40 DAS and boron was applied by four levels viz., B0: control, B1: 80% recommended dose as basal + rest 20% as foliar spray (FS) at pre-flowering (PF), B2: 60% RD as basal + rest 40% as FS at PF, B3: 40% RD as basal + rest 60% as FS at PF. The experiment was fully set up in a split-plot design with three replications. Two irrigations at 25 and 40 DAS result produced that the highest plant length, branches plant-1, leaves plant-1, dry weight plant-1. On the other hand, B3 (40% RD as basal + rest 60% as FS at PF) produced significantly the highest growth of lentil. Result also showed that the highest plant length (27.59 cm), number of branches (5.73) and plant dry matter (4.83 g) recorded from I2B3 combinations. Therefore, the combination of two irrigations at 25 and 40 DAS and boron at 40% RD as basal + rest 60% as foliar spray at pre-flowering might be considered as effective dose for the cultivation of lentil in Bangladesh.

A three yearsfield experiment was conducted at Regional Wheat Research Centre, Shyampur, Rajshahiduring 2014-15 to 2017-18 with an objective to observe the effects on soil fertility and performance of the crops under different tillage and residue management for rice-wheat (RW) systems by adding a third pre-rice crop of maize. The experiment was conducted in split plot design with three replication. The tillage options viz. (i) Strip tillage (ST) (ii) Permanent bed (PB) and (iii) conventional (CT) tillage; two crop residue management, viz. (i) 0%=no residue and (ii) 30% residue retention were studied. The results indicated that keeping 30% crop residue in the field with minimum disturbance of soil had significant contribution on grain yield of wheat-maize-rice sequence compare to conventional practice of well-till without crop residue retention.The permanent bed planting system gave the highest yields of wheat (4.37 tha-1), maize (7.31 tha-1) and rice (4.40 tha-1) and followed by strip tillage and lowest in conventional tillage. Among the residue management, 30% residue retention showed the highest yields of wheat (4.46tha- 1), maize (7.39 tha-1) and rice (4.69 tha-1). Considering economic performance of all tillage systems, the permanent bed planting system performed the best among all other tillage options and followed by strip tillage. Contrarily, 30% residue retention gave the highest yield and increased 0.12-0.14% organic matter into the soil with more productive.The results indicates that, both tillage systems coupled with 30% residue retention might be a good option for higher yield as well as soil fertility for Wheat-Maize- Taman rice cropping pattern in drought prone areas of Bangladesh.

A pot experiment was laid down at the Department of Agronomy, Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur from November 2018 to March 2019 to improving the salinity tolerance in Foxtail millet (BARI Kaon 1) using different plant growth regulators with different doses. Two salinity levels, i) control (0mM NaCl) and ii) 80 mMNaCl were maintained after 14 days of sowing to harvest. The plant growth regulators i) Humic acid (HA): a) @ 5 gL-1 water b) @ 10 gL−1water ii) Gibberellic acid (GA3): a) @10 g L-1water b) @20 g L-1water iii) Salicylic acid (SA): a) @ 50 g L-1water b) @ 100 g L-1water were sprayed at 7 days interval from salt imposition. The experiment was in a completely randomized design (CRD) with three replications. Results revealed that plant growth regulators improved the growth and yield performance of Foxtail millet under both control and saline conditions. Amelioration of salinity tolerance in Foxtail millet was well associated with lower proline content, higher chlorophyll content and SPAD value as well as dry matter production, which facilitated the Foxtail millet yield due to application of plant growth regulators. Among the plant growth regulators, humic acid (HA) @ 5 g L-1 water was the best treatment to improving the salinity tolerance in foxtail millet under saline condition. Bangladesh Agron.

An experiment was conducted to study the effects of water deficit stress on morphophysiological parameters in soybean plant in pots at the Department of Agronomy, Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur, Bangladesh during February to June, 2018. Seven soybean genotypes namely,i) G00081 ii) G00056 iii) Shohag iv) G00078 v) G00137 vi) G00035 and vii) G00060 were grown in two watering regimes viz. control (80% of the field capacity) and water deficit stress (50% of the field capacity). Morpho-physiological traits including plant height, number of leaf, relative water content, water saturation deficit, chlorophyll, proline, dry matter and yield were investigated. Results indicated that genotypic variability was found in water deficit stress tolerance in soybean. It was found that leaf of the genotype G00081 maintained higher water content, higher accumulation of prolineas well as less reduction of chlorophyll compared to other genotypes studied. Total dry matter accumulation and grain yield plant-1was also higher in this genotype. Genotype G00081 also showed relatively higher water deficit stress tolerance. On the contrary, G00035 was found to be susceptible showing lower yield. Higher water deficit stress tolerance in G00081 was attributed to higher relative leaf water and chlorophylls with accumulation of higher amount of proline. Bangladesh Agron. J. 2019, 22(2): 41-54
