Item DETERMINATION OF THE FREQUENCY OF IRRIGATION ON THE YIELD OF SELECTED MUNGBEAN VARIETIES(Department of Agricultural Botany, 2009) SHARMIN, SOHANAThe experiment was conducted at the Agricultural Botany, field of Sher-e-Bangla Agricultural university. Dhaka during the Rabi season from October, 2011 to February. 2012 to study the influence of water deficit on the morphophysiology and yield attributes of mungbean. In the experiment the consisted of five mungbean varieties viz. BARI mung 2. BARI mung 3, BARI mung 4, BARI mung 5. BARI mung 6 and four different number of irrigation, 11 = three irrigations. 12 = two irrigations. 13 = One irrigation, 14 = no irrigation. The experiment was laid out in a two factors randomized complete block design (RCBD) with three replications. The days to emergence was not significantly affected due to the variety of mungbean. The maximum days to emergence was obtained from days to emergence BARI mung 4. Results showed that a significant variation was observed among the treatments in respect of majority of the observed parameters. The tallest plant was obtained from BARI mung 2. Treatment BAR.!mung 3 produced maximum number of leaves and branches. The earliest of days to first flowering, the longest time of days to last flowering, the earliest of days to first pod setting and days to first maturity were found in BARI mung 2. The highest numbers of flower per plant, pod length and number of seeds per plant (5.04) was recorded in BARI mung 2. The highest yield (1.39 tfha) was recorded in BARI mung 2. The tallest plant was obtained from three irrigation levels. Treatment three irrigations produced maximum number of leaves and branches. The earliest of days to first flowering, the longest time of days to last flowering, the earliest of days to first pod setting and days to first maturity were found in three irrigations. The highest number of flowers per plant and pod length was produced in three irrigations. The highest number of seeds per plant (6.92) was recorded in three irrigations. The maximum yield (1.31 t/ha) was obtained from three irrigations. Interaction effect of variety and number of irrigation had a significant variation on all parameter. The tallest plant and highest number of leaves were obtained from BARI mung 2 with three irrigation treatment. The earliest of days to first flowering, the longest time of days to last flowering, the earliest of days to first pod setting and the earliest of days to first maturity were found in BARI mung 2 with three irrigations. The highest number of flower per plant, pod length was produced in BARI mung 2 with three irrigations. The highest seeds weight per plant (10.63g) was obtained from BARI mung 2 with three irrigations. The highest yield (1.62 tlha) was obtained from BARI mung 2 with three irrigations.Item PHENOLOCICAL CHANGES, YIELD AND QUALITY OF TOMATO (Lycopersicon esculentwn) AS INFLUENCED BY DIFFERENT DOSES OF FERTILIZERS AND COWDUNC(Department of Agricultural Botany, 2009) YESMIN, SABINAAn experiment was conducted in the field of Sher-e-Bangla Agricultural University. Dhaka, Bangladesh during the period from November 2008 to April 2009 to study the phenology. yield and quality of tomato 'Lycoperxicon esculentum) with different doses of Fertilizers and cowdung. The two factorial experiment was laid out in a randomized complete block design (RCI3D) with three replications. The experiment consisted of two factors, viz, factor A: Four levels of chemical fertilizer, F0: control; F1: 150 kg N + 100 kg P205 + 100 kg K20 + 10kg S/ha; 172: 200 kg N + 150 kg P205 + 125 kg K20 + 15kg S/ha and F3: 250 kg N + 200 kg P205 + 150 kg K20 + 20 kg S/ha and factor 13: Three levels of cowdung as Co: Control; C1: 5 ton cowdung/ha and C2: 10 ton cowdung/ha with the following treatment combinations of F0CO3 F0C1. F0C2. F1CO3 F1C1, F1C21 F2C0. F2C1, F2C2, F3C4, 173C1 and F3C2. The urea, TSP, MP and gypsum were used as a source of N. P205. K20 and S. respectively. The seedlings of tomato var. BARI Tomato-6 (chaiti) were raised at the nursery of the university farm. The plant height, number of leaves per plant and number of branches per plant were increased at different days after transplanting almost in the all treatments. The highest plant height (127.04 cm) and the lowest plant height (101.24 cm) were recorded with F1C2 and F0C2 treatment. respectively. The maximum number of leaves and branches were observed in F2C1. The highest number of flower cluster per plant, number of flowers per plant, number of flowers per cluster, number of fruits per plant. fruit length, fruit diameter and yield per hectare (67.93 i/ha) were observed from F2C1 treatment. In addition, F2C1 treatment produced tomato fruit earlier (76.30 days) than other treatments with highest shell life (10.67 days). Separately, the highest content of total soluble solid of tomato was recorded in F2C2 treatment. No significant differences were observed between F1C2 and 172C1 treatment in respect of phenology. yield and quality of tomato. The treatment combinations of F1C2 might be recommended for tomato production rather than 1`2C1, due to sources of plant nutrients through cowdung is better than inorganic sources to keep safe environment.
