The present study was set up to explore the role of exogenous salicylic acid (SA) and silicon (Si) application on the growth and yield performance of two contrasting rice genotypes, namely BRRI dhan41 (salt-tolerant) and BRRI dhan49 (salt-sensitive) under salinity. The experiment was laid out in a randomized complete block design with three replications and four SA and Si treatments such as control (tap water), 100 ppm SA, 100 ppm Si (as CaSiO3) and, co-application of SA and Si (50 ppm each). Results revealed that the maximum plant height (125.2 cm), fresh weight of shoot (267.3 g) and maximum K+/Na+ (5.2) were obtained in BRRI dhan49 after sole application of Si under salt stress. Besides, the number of grains per panicle and grains per hill significantly increased in BRRI dhan41 after the sole application of SA (64 and 46%, respectively) and co-application of SA and Si (29 and 21%, respectively), and in BRRI dhan49 with sole SA (182 and 277%, respectively) and Si (75 and 446%, respectively) compared with their respective controls. Besides, we observed that the K+/Na+ was increased where the shoot accumulation of Na+ reduced significantly in both rice varieties after sole and co-application of SA and Si compared with the untreated plants. However, the present findings showed new dimensions regarding the beneficial effects of Si on rice plants which could effectively be utilized to grow and maximize rice production in the saline-prone coastal areas of Bangladesh encountering detrimental effects of salt stress on rice. \u0000Bangladesh Agron.

This research article aims to test the hypothesis that the leaf cutting as an agronomic practice could be a better prospective in increasing rice grain production. An experiment was carried out in the experimental field of Sher-e-Bangla Agricultural University, to assess the effect of leaf cutting on plant growth and yield of selected BRRI released Aman varieties. The experiment consisted of five rice varieties namely BRRI dhan32, BRRI dhan33, BRRI dhan39, BRRI dhan62, and BRRI dhan56 treated either as control or leaf cutting (except flag and penultimate leaf). The experiment was laid out in randomized complete block design (RCBD) with three replicates. Leaf cutting was observed with detrimental effect on the usual plant growth and yield performances. Irrespective of all studied varieties, the highest value was obtained while no leaf cutting was performed. BRRI dhan39 was found to be the highest yield producing variety in terms of greater flag leaf length, leaf breadth, flag leaf area, required less time to grain filling, filled grain panicle-1, filled grain%, 1000-grain weight, grain yield and harvest index in leaf cutting condition followed by BRRI dhan32 in terms of plant height, chlorophyll content, tiller hill-1 and straw yield. No significant differences in yield contributing parameters except the panicle hill-1 were observed in leaf cutting condition compared to control. Leaf cutting at heading (except flag leaf and penultimate leaves) reduced average 10-20% loss of grain yield. BRRI dhan62 shown highly affected by leaf cutting compared to the rest other varieties. Therefore, it can be concluded by suggesting that leaf cutting reduces plant functional efficiency which can be improved by enhancing photosynthetic capacity through proper management of leaf architecture. \u0000Bangladesh Agron.

Treatments included in the experiment were: T1= Maize normal row (MNR) +1 row dwarf yard long bean (DYLB), T2= Maize paired row (MPR) + 2 rows DYLB, T3= MPR +3 rows DYLB, T4= MPR + 4 rows DYLB, T5= Sole maize (60 cm x 20 cm) and T6= Sole DYLB (40 cm x 25 cm). Light availability on DYLB decreased with the increase of shade produced by maize canopy over the time up to 105 DAS. The lowest light availability on DYLB was observed in T1 treatment and the highest light availability in sole DYLB (T6). The maximum grain yield of maize was observed in sole maize decreased by 1-4 % among the intercrop treatments. The highest maize equivalent yield (13.75 t ha-1), gross return (Tk. 247500 ha-1), gross margin (Tk. 139000 ha-1) and benefit cost ratio (2.28) were observed inT3 followed by T1.

The treatments were i) Mustard (var. BARISarisha-14)-Boro-Fallow cropping pattern, ii) Mustard (var. BARI Sarisha-15)- Boro-Fallow cropping pattern, iii) Mustard (var.

The results revealed that the mean crop duration of improved cropping pattern ranged 192-195 days by inclusion of mustard. Rice equivalent yield of improved cropping pattern was 9.51-10.04 t ha-1 year-1 which was 46% higher than that of existing pattern (5.37 t ha-1 year-1). Land use efficiency (53%) of improved cropping pattern were 9 and 47% higher, respectively than those of existing cropping pattern.
