An experiment was conducted at the Hill Agricultural Research Station, Khagrachari from June to November 2004 to find out the effect of nitrogen (60, 80, 100 and 120 kg/ha) and phosphorus (80, 100 and 120 kg/ha) on the growth and yield of okra in hill slope condition during rainy season. The highest yield (16.73 t/ha) was obtained from 100 kg N/ha, which was statistically identical to 120 kg per hectare. In case of phosphorus, the highest yield of 15.77 t/ha was obtained from 120 kg P 2 O 5 /ha and was closely followed by the dose of 100 kg P/ha (4.73 t/ha). Considering the treatment combinations, the highest yield (19.22 t/ha) was produced by N 100 P 120 and there were no significant variations among N 100 P 100 , N 120 P 100 and N 120 P 120 . The highest gross return (Tk.193200) and net return (Tk.146l40) were obtained from N 100 P 120 . The BCR was also higher (4.08) under the same treatment combination.

The study was conducted at the Hill Tracts Agricultural Research Station, Ramgarh during two years in 2007 and 2008 to evaluate the variability and performance of selected 11 velvet apple germplasm. A lot of variations in different parameters were observed among the trees. The age of plant varied from 7 to 25 years having tree volume 58 m3 to 428 m3. The number of fruits ranged from 42 to 674 per plant with single fruit weight 118 to 283 g. The length and diameter ranged from 6.63cm to 7.7cm and 5.73cm to 8.3cm, respectively. The maximum edible portion (68.3%) was recorded in DD RAM 011, while it was the lowest (47.6%) in DD RAM 001. The highest TSS% ranged from 7.28% to 14.9%. Highest yield per plant (103.67 kg) was observed in DD RAM 001 and it was lowest in DD RAM 008 (5.99 kg). All the parameters showed poor correlation among them. Considering the factors of weight and size, edible portion %, TSS %, taste, sweetness, and yield per plant, the line DD RAM 011 was found better than others.

An experiment was conducted at the Hill Agricultural Research Station, Khagrachari from May to November 2004 to find out the effect of planting time (1 st week of June, July, August and September) and plant spacing (60 × 30 cm, 60 × 40 cm and 60 × 50 cm) on the yield and yield components of okra in hill slope condition during rainy season. The highest yield (12.53 t/ha) was obtained by the planting in July which was at par with June (11.69 t/ha). In case of plant spacing, the highest yield (9.02 t/ha) was recorded from close spacing at 60 x 30 cm that was statistically different from other two spacing and the widest spacing of 60 x 50 cm produced the lowest yield (8.06 t/ha). The treatment combination July sowing with 60 x 30 cm plant spacing produced significantly highest yield (12.86 t/ha).

Field experiments with French bean comprising two varieties (BARI bush bean-1 and BARI bush bean-2), three plant densities (500 x 103, 333 x 103, and 250 x 103 plants/ha as maintained by 20 x 10, 30 x 10, and 40 x 10 cm spacings, respectively) and three levels of N (0, 60, and 120 kg/ha) were conducted at the Agricultural Research Station, Raikhali in the district of Rangamati during the winter (rabi) seasons of 2004-05 and 2005-06. BARI bush bean-1 outyielded BARI bush bean-2. The lowest plant density (250 x 10 plants/ha) recorded significantly higher values of growth and yield attributes, except plant height which was the maximum with the highest plant density of 500 x 103 plants/ha. The highest plant density of (500 x 103 plants/ha) resulted in the highest pod yield in comparison with the lower and medium plant densities. Application of 120 kg N/ha coupled with the highest plant density (500 x l03 plants/ha) gave the maximum pod yield of 34.3 t/ha and 30.2 t/ha in BARI bush bean-I and BARI bush bean-2, respectively.
