  A field experiment on cauliflower (var. Rupa) was conducted in two consecutive years from November 2000 to March 2002 in sandy clay loam soil at the Agricultural Research Station, Raikhali, Rangamati Hill District to observe the effect of irrigation and mulch materials on its yield, yield attributes and profitability. Twenty combinations of treatments consisting of four levels of irrigation (no irrigation = control, irrigation at 7, irrigation at 14 and irrigation at 21 days interval) and five levels of mulching (non mulch (control), black polythene mulch, rice straw mulch, sun grass mulch and mango leaves’ mulch) were used for this trial. Irrigation at 7 days interval and mulching with black polythene independently as well as in combination produced maximum values for yield attributes and marketable yield of cauliflower. The highest curd yields of 30.38 and 29.40 t ha-1 were obtained from 7 days irrigation interval with black polythene mulch in 2000-01 and 2001-02, respectively. The lowest curd yields of 10.50 and 10.04 t ha-1 were obtained from without irrigation and mulching in 2000-01 and 2001-02, respectively. Seven days interval irrigation and mulching with forest leaves (mango leaves) in combination gave the highest benefit cost ratio (6.51) closely followed by 14 days interval irrigation with the same mulch (6.48). But maximum marginal rate of return (1156.89%) was recorded from the combination of 14 days interval irrigation and mulching by mango leaves followed by irrigation at 21 days interval with the same type of mulch (936.92%).

  An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, during the period from May to November 1998 to investigate the effect of green manures and different levels of nitrogen on the growth performance of transplant aman rice (cv. BRRI dhan 32). The experiment consisted of 3 green manuring crops viz. Sesbania rostrata, Sesbania aculeata and Crotalaria juncea and 5 levels of nitrogen viz. 0, 20, 40, 60 and 80 kg ha-1. Growth attributes such as leaf area index, crop growth rate and net assimilation rate increased up to 67 DAT irrespective of green manure crops and different levels of nitrogen and thereafter declined. On the other hand, plant height and leaf area duration increased with the increasing levels of nitrogen in combination with green manuring crops. Application of 40 kg N ha-1 along with Sesbania rostrata green manuring showed the best performance in respect of grain yield and net assimilation rate of transplant aman rice. S. aculeata exhibited similar behaviour as that of S. rostrata but Crotalaria juncea showed relatively poor performance in respect of growth attributes of rice due to less amount of biomass added during incorporation.

  The experiment was conducted to find the effect of different cultivars and time of nitrogen application on the growth and yield of separated tillers of transplant aman rice. Tillers of three rice cultivars (BRRI Dhan 32, BR 23 and BR 22) and five timings of nitrogen application were used as treatments. The individual effect of var. BR 23 and the three equal splits of application of nitrogen as basal, at early tillering and at panicle initiation stages gave the best results on plant height, no. of tillers hill-1, no. of leaves hill-1, leaf area index, no. of grains panicle-1, weight of 1000 grains, grain yield, straw yield, biological yield and harvest index having 121.21 and 122.54 cm, 9.10 and 9.26, 36.72 and 39.91, 4.92 and 4.68, 118.60 and 118.50, 23.98 and 22.33 g, 4.55 and 4.79 t ha-1, 6.15 and 6.60 t ha-1, 10.70 and 11.40 t ha-1, 42.62 and 41.24 %, respectively. The interaction effect of var. BR 23 and T2 was the highest on these parameters. Rice var. BR 23 and three splits of nitrogen application may be used for increasing growth and yield of separated tillers of transplanted aman rice.
