Given the growth-enhancing capabilities and other regulatory roles of Pro and GB, the current study was conducted to assess their function in imparting salt stress resilience in proso millet (Panicum miliaceum L). Proso millet plants were subjected to two levels of salt stress (S1 = 150 mM; S2 = 300 mM). Foliar applications of Pro (0.5 mM) and GB (0.5 mM) were provided under control and salt-stressed conditions at 10-day intervals twice. Compared to control conditions, plant growth, fresh and dry weight, leaf relative water content (RWC), SPAD value, and yield-contributing attributes noticeably decreased under salt stress. In contrast, plants supplemented with Pro and GB exhibited enhanced characteristics. Moreover, growth and yield parameters improved in salt-treated proso millet plants when supplemented with Pro and GB. These results suggest that the foliar application of Pro and GB can alleviate salt-induced oxidative stress in proso millet plants by modulating the antioxidative defense.

The experiment was carried out in a randomized complete block design (RCBD), with two factors. Factor A: three varieties as- BR26, BRRI dhan48, and BRRI dhan82; and Factor B: five levels of nitrogen rates as- 0, 40, 60, 80, 100 kg ha−1. The experimental data show the individual effect of variety and nitrogen (N) rate was significant in the case of N concentration, N uptake in grain and straw, and nitrogen harvest index (NHI). Overall, increasing N rate increases grain and straw's concentration irrespective of varieties. But higher N concentration and uptake were observed in the N rate of N60-N100 kg ha−1 in all varieties. Among the varieties, BRRI dhan82 observed higher N uptake (61.23 kg ha−1) in grain. Higher total N uptake was also observed in BRRI dhan48 at 80 kg N ha−1. NHI ranged from 55 to 72 % in different N levels, indicating 55 to 72% of the absorbed N translocated to the grains, and 45% to 32% remained in the dry matter within varieties. The estimated economic nitrogen dose for maximum yield was determined by regression analysis, and found that N rates of BR26, BRRI dhan48, and BRRI dhan82 were 97, 95, and 55 kg ha−1, respectively. The findings of this study indicated that the response of different N rates on three Aus varieties was linear up to 80 kg N ha−1 might be owing to better N uptake that made yield increase after that decreasing.

BRRI dhan28) in T. Aman-Mustard-Boro rice cropping pattern. The experiment comprised three crop establishment methods viz. traditional puddled-transplanting (TPT), unpuddled-one pass in dry condition (UDC), unpuddled-zero tillage (UZT) and five levels of fertilizers viz., 100-60-40-60-10 N-P-K-S-Zn kg ha-1 at recommended (RD) dose (F1), N-K-S-Zn at RD plus 50% P (F2), N-P-S-Zn at RD plus 50% K (F3), P-K-S-Zn at RD plus 75% N as Guti urea (2.7 g/4 hills) (F4), P-K-S-Zn at RD plus 75% N as pilled urea (F5). The experiment was laid out in a split -plot design with 4 replications with crop establishment method in the main- plots and fertilizer management in the sub-plots. Grain yield was not significantly influenced by crop establishment method, fertilizer management and their interactions. However, numerically the maximum grain yield of 3.19 t ha−1 was found in both unpuddled-one pass in dry condition (UDC) and unpuddled-zero tillage (UZT) with 3.32 t ha−1 in P-K-S-Zn at RD plus 75% N as pilled urea (F5) and 3.47 t ha−1 in unpuddled-one pass in dry condition with P-K-S-Zn at RD plus 75% N as pilled urea and traditional puddled-transplanting with P-K-S-Zn at RD plus 75% N as pilled urea. Similar higher gross margin (Tk. 26629 and Tk. 27428) and benefit cost ratio (1.61 and 1.60) was also observed in UZT × F4 and UDC × F5, respectively. So, it can be concluded that unpuddled-zero tillage with P-K-S-Zn at RD plus 75% N as Guti urea (UZT × F4) and unpuddled-one pass in dry condition with P-K-S-Zn at RD plus 75% N as prilled urea (UDC × F5) is the beneficial technique for Boro rice (var.

The nano particles are significant for their particle shape, potential reactivity, tunable pore size and high surface area. A pot experiment was conducted at the Department of Agronomy, Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur during Rabi season (December 2020 to March 2021) to evaluate the effects of foliar spray of nano zinc (ZnO) in varying doses (0, 100 and 200 ppm) on growth, dry matter accumulation and yield of soybean under drought (40% of field capacity, FC) and control (80% of FC) conditions. The trial was conducted in a completely randomized design (CRD) with three replications. Plant height; fresh and dry weight of leaf, stem and whole plant; number of pods per plant; number of seeds pod-1; 100-seed weight and seed yield of soybean were suppressed due to drought stress. Under both drought and control conditions, the foliar application of nano zinc substantially improved the growth, dry matter accumulation and yield of soybean. In drought condition, the foliar spray of 200 ppm nano zinc solution increased plant height, total fresh and dry weight by 21.69, 34.23 and 76.03%, respectively. In drought conditions, nano Zn particles at 100 and 200 ppm increased seed yield by 26.79 and 63.50%, and in control conditions by 13.07 and 23.56%, respectively. As such the results indicated that foliar application of nano zinc oxide improved growth, yield and drought tolerance of soybean. \u0000Bangladesh Agron.
