ARFAN An experiment was conducted at the Horticulture Farm of Sher-e-Bangla Agricultural University. Dhaka during the period from October 2004 to February 2005 to study the , . effect of different levels of fertilizer and manure viz. control. organic manure (23.11- t/ha), inorganic fertilizer (Urea 3~2 k&/lta, MP 180 kglba, TSP 158 kgIha) and mixture of organic and inorganic fertilizer (Cowdung 11.5 tJha, Urea 177 kg/ha, TSP 62 kg/ha and MP 63 kglha) and different mulching materials viz. no mulch ~), rice straw (MI). water hyacinth (M2) and black polythene (M3) on the growth and yield of lettuce. The experiment was conducted in the"'Rand()mizedComplete Block Design ~ ... (RCBD) with three replications. "APpliCation of different levels 'of fertilizer and manure significantly influence the growth and yield of lettuce. Organic plus inorganic fertilizer treatment resulted in the highest gross (46.01 tJha) and marketable yield (45.46 t/ha). The highest yield (45.7t1ha) was recorded from black polythene mulch, while the lowest (38.71t/ha) was recorded from unmulch treatment. The combined effect of various levels of fertilizer and manure as well as mulches were ..... also found significant incase of lettuce production. The use of organic plus inorganic fertilizer with black polythene mulch produced the highest gross (50.27 t/ha) and marketable yield (49.62 tlha). The lowest gross (35.44 tJha) and marketable yield (34.9 t/ha ) were recorded from the control treatment where no manure and fertilizer as well as no mulch were used. The benefit cost ratio (BCR) was the maximum (3.23) in the treatment combination of cowdung with water hyacinth mulch whereas, the minimum (2.09) was recorded from the water hyacinth with no fertilizer treatment A Thesis Submitted to Department of Entomology, Faculty of Agriculture.

NAHIYA, ABU SHAMIM MOHAMMAD A field experiment ":,,asconducted at the Horticulture Farm of Sher-e-Bangla Agricultural University, Dhaka, during October 2004 to February 2005 to study the effects of different intercropping practices and levels of nitrogen on the growth and yield of carrot. Three different intercropping practices viz. non-intercrop, Red amaranth intercrop and Bengal spinach intercrop and three levels of nitrogen viz 0, 200, 250 kg per hectare were used in the study. Carrot was sown as a sole crop at a spacing of 25 x 10 em and Red amaranth and Bengal spinach were sown in between the two rows of carrot as intererops. The experiment was carried out in Randomized Complete Block Design with three replications. Leafy vegetables intereropping had significant influence on yield and yield attributes of carrot, except, root diameter. The highest root length (16.59 ern), fresh . weight of root per plant (135 g), and marketable yield (45.40 t/ha) were recorded from control intercrop (10) and lowest were found from Bengal spinach intercrop (i2). Nitrogen (N) had remarkable effect on growth and yield of carrot. The maximum root length '(16.83 em), root diameter (4.98 ern), fresh weight of root per plant (141.40 g), and marketable yield (47.06 t/ha) were obtained from 25b kg Nlha '(N2) and minimum from control (No). In respect of combined effect control intercrop with 250 kg N/ha (lON2) produced highest root length (17.3Tcm), root diameter (5.33 em), fresh weight of root per plant (161.70 g) and marketable yield (52.13 t/ha), Highest intercrop yield (28.33 t/ha) obtained from the IlN2 (Red amaranth intercrop and 250 Kg N/ha) treatment. Economic analysis showed that Red amaranth intercrop and 250 Kg N/ha gave maximum economic benefit with the benefit cost ratio of 5.22.

There were two variety of sunflower viz. Kironi, Sunwheat-103 and four intercrop viz. non­ intercrop, Red amaranth, Bengal spinach and Pak-choi. The treatment combinations were set in a Randomized Complete Block Design (RCBD) with three replications. Growth and yield parameters were recorded and the cost benefit analysis was computed to assess the yield potentiality and profitability of sunflower and intercropping of leafy vegetable. Sunflower variety Had significant effect on plant height, number of leaves, diameter of the head, seed yield, 1000 seed weight and oil content. The highest seed yield (961.11 kg/ha) was obtained from variety Kironi. Intercroppe.d leafy vegetables intercropping had remarkable effect on growth, flowering and yield. The combinations of variety and intercrop significantly influenced the plant height, number of leaves, diameter of the head, seed yield and 1000 seed weight. The highest seed yield (1133 kg/ha) was found in the treatment combination of tall variety sunflower (Y.r) and control intercrop (Io). Highest intercrop yield (13.69 t/ha) obtained from the dwarf variety and Red amaranth intercrop (VDIL) treatment combination. Economic analysis showed that tall variety sunflower (Vr) with Red amaranth intercrop (I1J gave the best economic return (Tk 77539/ha) and benefit cost ratio of 2.4 5.

REZAUL The present study was conducted at the Biotechnology Laboratory, Biotechnology Division, Bangladesh Agricultural Research Institute (BARI), Gazipur during the period from September, 2004 to June, 2005 to investigate the effect of different concentrations of BAP and NAA on virus free plant regeneration, shoot multiplication and different concentrations of IBA and IAA on in vitro root formation ofbanana cv. BARI-I. The culture meristem first turned brown in colour in 4-5 days and after 30-50 days later a green globular hard coat mass grow to be round in shape producing a ball like structure. From this ball like structure adventitious plantlets were developing. Among the different concentration 7.5 mgl," BAP + 0.5 mgl," NAA showed the highest shoot proliferation 0.75, 2.75 and 6.25 shoots per explant at 10, 20 and 30 DAI respectively. The longest shoot was produced by the treatment concentration 7.5 mgl," BAP + 0.5 mgl," NAA treatment (1.03, 2.45 and 3.38 cm) at 10, 20 and 30 DAI respectively. The maximum number of leaves (2.50, 3.25 and 7.00 leaves/explant at 10, 20 and 30 DAI) produced on the medium supplemented with 7.5 mgl," BAP and 0.50 mgl," NAA. The longest leaves was produced by the treatment concentration 7.5 mgl," BAP + 0.5 mgl," NAA treatment (0.85, 2. 70 and 4.23 cm at 10, 20 and 30 DAI) respectively. For root initiation half strength MS medium supplemented with different levels of IBA (0, 0.5, 1.0 and 1.50 rngl.") and IAA (0, 0.5 and 1.0 mgL"1) in order to allow root formation. Root numbers varied with different concentrations of IBA and IAA. The highest number of roots were produced by 0.5 mgl." IAA + 0.5 mgl," IBA (3.50, 4.50 and 6.50 per explant respectively). The highest length was observed at 10, 20 and 30 DAI in the treatment concentration 0.5 mgl," IAA and IBA (2.93, 4.63 and 5.88 cm) which was statistically significant. Meristem derived plantlet transferred to polybags containing 1 : 1 (ground soil : cowdung) mixture after 7 days hardening in room temperature (28-30°C) and established plantlet is ready for planting.
