AGROFORESTRY PRACTICES WITH RED AMARANTH DURING THE EARLY ESTABLISHMENT PERIOD OF MORINGA PLANTATION SUMONA, SINTHIA RAHMAN A study was undertaken to find out the response of red amaranth in association with drumstick (Moringa oleifera) sapling. The experiment was conducted at agroforestry experimental field, Sher-e-Bangla Agricultural University, during February to March 2017. Four treatments namely, T 0 = Open field referred to as control, T 1 = 12 cm distance from the tree base, T 2 = 24 cm distance from the tree base and T 3 = 36 cm distance from the tree base were used in Randomized Complete Block Design (RCBD) with four replications. Yield contributing characteristics of red amaranth and growth perimeters of drumstick as influenced by the management practice were also determined. At the time of harvest, the highest plant height among the treatments was observed in T 3 , which was 9% less than that of control condition and 22% less stem girth was observed in T 1 compared to control. The highest no. of leaves were observed in T 2 treatment, which was 15% less than that of control condition. In case of yield contributing characteristics of red amaranth, 20% less shoot length and 18% less root length were observed in treatment T 2 and T 1 respectively than that of control condition. Apart from control, the highest fresh weight, dry weight and yield were performed under T 1 treatment. Therefore, at treatment T 1 , 16% less fresh weight, 13% less dry weight and 16% less yield were observed compared to that of control condition. But the moisture content of red amaranth (94.27%) was the highest in T 2 treatment and dry matter content of red amaranth (6.38%) was the highest in T 1 treatment. In case of drumstick, at the harvest of red amaranth the highest no of buds were found in T 3 treatment and lowest no. of buds were found in T 2 treatment, but the highest bud length was found in T 1 treatment. Therefore, it was observed that best yield performance of red amaranth at treatment T 1 in association with Moringa sapling. So, farmer can easily cultivate Moringa tree in association with red amaranth maintaining 12 cm distance from tree base without much loss.

INTERACTIVE EFFECT OF NITROGEN AND PHOSPHORUS ON GROWTH AND YIELD OF CHILI (Capsicum annuum L.) IN ROOFTOP GARDEN MAHMUD, MD. KHALID Roof top garden is suitable for vegetables cultivation in our country. Chili is an important vegetable of robi season. Nitrogen (N) and phosphorus (P) play an important role in growth of chili. An adequate amount of N and P exerts significant effect on the growth and yields of this crop. This experiment was done to evaluate suitable dose of N and P for different growth and yield contributing parameters of chili in rooftop garden. The experiment was conducted at the roof of third floor of Biotechnology department of Sher-e-Bangla Agricultural University, Dhaka during October, 2016 to March, 2017. The two factorial experiments were laid out in Completely Randomized Design (CRD) with three replications. Three levels of nitrogen N 0 : 0 kg N ha- 1 , N 1 : 100 kg N ha- : 130 kg N ha- 1 , P 2 1 and three levels of phosphorous P : 80 kg P 2 O 5 ha- 1 0 : 0 kg P 2 O 5 ha- 1 , P 1 1 : 50 kg P were used in this experiment. Growth and yield contributing parameters significantly influenced by different doses of nitrogen and phosphorus fertilizers. The dose of N treatment gave the highest plant height (87.45 cm) and most of the growth parameters increased with increasing nitrogen levels up to N 2 treatment. The dose of P 2 treatment gave the highest plant height (79.45 cm) and most of the growth parameters increased with increasing phosphorus levels up to P 2 treatment. The treatment combination N 2 and P gave the highest fruit diameter (4.26 cm), fruit length (11.913 cm), yield of fruits plant- 2 1 (200 g), average fruit yield plot- 1 (0.81 kg), individual fruit weight (0.84 g) and average fruit yield (6.79 ton/ha). Based on the present results, it can be suggested that the combined use of 130 kg N ha- 1 with 80 kg P 2 O 5 ha- 1 increased plant growth and fruit yield of chili in rooftop garden. It is apparent that growth and yield of chili may be increased by using nitrogen and phosphorus fertilizer.

TREE-CROP INTERACTIONS DURING THE EARLY ESTABLISHMENT PERIOD OF MORINGA PLANTATION AHMED, ARIF An experiment was conducted in Agroforestry Field Laboratory at Sher-e-Bangla Agricultural University, Dhaka to find out the effect of planting distances on growth, yield and yield attributing characters of stem amaranth (Amaranthus oleraceus) during the early establishment period of Moringa (Moringa oliaferae) trees. The growth of Moringa as influenced by management practices was also determined. The study was conducted during the period from January to April, 2018 by following Randomized Complete Block Design (RCBD) comprising of four treatments with four replications. Four treatments were T 0 (open field condition as control), T (6 inches distance from tree base), T 2 (12 inches distance from tree base), T 3 1 (18 inches distance from tree base). Significant variations were observed in respect of all characters at different days after sowing (DAS) with different planting distances. At harvest (50DAS), the maximum plant height of stem amaranth (59 cm), number of leaf per plant (25 cm) was recorded in control condition (T treatment) and minimum plant height (49 cm), number of leaf per plant (20) was recorded in T 0 treatment. The highest leaf length (10 cm) and leaf breadth (5 cm), stem girth (6 cm), stem length (61 cm), root length(16 cm), shoot and root fresh weight (74 g and 16 g), shoot and root dry weight(4 g and root 1 g) and green yield (14 t/ha) were observed in open field condition (T 3 treatment). The yield was reduced by 15% in T 1 0 treatment (12 t/ha) compared to open field condition. The fresh yield of stem amaranth under T 2 (10 t/ha) and T (10 t/ha) treatment with association of Moringa was recorded 26 % lower than the plants which were grown under control condition (T 3 treatment). The growth characters of M. oliaferae were also enhanced in association with stem amaranth. At harvest of stem amaranth, maximum bud length(8cm) and bud number (4) of Moringa sapling were also recorded in T treatment thus showing its potential to be used in Moringa based agroforestry farming system in large-scale.

PERFORMANCE OF NITROGEN AND PHOSPHORUS ON THE GROWTH AND YIELD OF INDIAN SPINACH (Basella alba L.) ON ROOF TOP GARDEN ROY, NILIMA The experiment was conducted on the roof top of Biotechnology Department of Sher-e-Bangla Agricultural University, Dhaka, during the period from September 2016 to January 2017 to optimizing the appropriate levels of nitrogen (N) from urea and phosphorus (P 2 O 5 ) from TSP on growth and yield of Indian Spinach. The experiment was laid out in Completely Randomized Design (CRD) with three replications having two factors viz., Factor A: Three levels of nitrogen (N) i.e. N 0 (0 kg N ha -1 or Control), N 1 (120 kg N ha ii -1 ), N 2 (180 kg N ha -1 ); and Factor B: Three levels of phosphorus (P 2 O 5 ) i.e. P 0 (0 kg P 2 O 5 ha -1 or Control), P 1 (120 kg P 2 O 5 ha -1 ), P 2 (140 kg P 2 O 5 ha -1 ). The seeds of Indian Spinach (BARI Puishak -2) were collected from Bangladesh Agricultural Research Institute (BARI), Joydebpur, Gazipur. A statistically significant variation was observed in respect of all characters at different days after sowing (DAS) in relation with different levels of nitrogen and phosphorous application. The doses of N 2 treatment showed the maximum plant height (96.62 cm), number of branches per plant (17.97), number of leaves per plant (93.21), leaf area (254.49 cm 2 ), yield per plot (947.81g plot -1 ), yield per hectare (20.43 ton), while the control treatment gave the lowest values. The doses of P 2 treatment showed the maximum plant height (84.58 cm), number of branches per plant (16.27), number of leaves per plant (84.23), leaf area (216.43 cm 2 ), yield per plot (887.87 g plot -1 ), yield per hectare (19.06 ton), while the control treatment gave the lowest values. The combined effect also showed significant differences. Among the treatment combinations, N 2 P 2 (180 kg N ha + 140 kg P 2 O 5 ha -1 ) showed the maximum plant height (98.21 cm), number of branches per plant (18.75), number of leaves per plant (95.56), leaf area (266.56 cm 2 ), yield per plot (970.22 g plot -1 ), yield per hectare (20.9 ton), while the control treatment gave the lowest value. The over all result suggests that N 2 treatment and P 2 treatment can be applied to boost up the production of Indian Spinach.
