EFFECTS OF SALINITY ON GERMINATION, INITIAL GROWTH STAGE AND NUTRIENT CONTENTS OF MUNGBEAN
(DEPARTMENT OF AGRICULTURAL CHEMISTRY, SHER-E-BANGLA AGRICULTURAL UNIVERSITY, DHAKA-1207, 2021-06) ISLAM, MONIRUL
The experiment was undertaken in February 2019 to June 2020 in the net house of Agricultural Chemistry Department, Sher-e-Bangla, Dhaka, Bangladesh effects of salinity on germination, initial growth stage and nutrient contents of mungbean. In this experiment, the treatment consisted of four mungbean varieties viz., V 1 = BARI Mung 5, V 2 = Binamung 5, V =Binamung 7 and five salinity levels (0, 3, 6, 9 and 12 dSm 3 = BARI Mung 6, V -1 ). The experiment was set in Completely Randomized Design (CRD) having two factors with three replications. Results showed that a significant variation was observed among the treatments in respect of majority of the observed parameters. The collected data were statistically analyzed for evaluation of the treatment effect. Data were collected on germination percentage, population density, plant height, number of leaves per plant, length of root. A statistically significant variation was recorded in terms of all the characters related to growth and chemical analysis. The maximum plant height, number of leavess per plant, length of root was produced by Binamung 7. The maximum plant height, number of leave per plant, length of root was observed in levels of 0 dS . Among the combined effects of varieties and salinity levels, plant height, number of leaves per plant, root length was found in Binamung 7 with 0 dSm level and at 3, 6, 9 and 12 dSm -1 salinity levels. Among the four varieties, K content was highest in BARI Mung 6 among the other three varieties. In both varieties K content decreased significantly with the increasing salinity level. Na content was highest in BARI Mung 5 than Binamung 7. N and P content was highest in BARI Mung 6. -1 4 -1
INFLUENCE OF SOWING DATE AND SPACING ON GROWTH AND YIELD OF SWEET PEPPER
(DEPT. OF HORTICULTURE, 2007) ISLAM, MONIRUL
An experiment was carried out at the Horticultural farm of the Bangladesh Agricultural Research Institute, Joydebpur, Gazipur, during September 2006 to April 2007 to investigate growth and yield of sweet pepper as influenced by sowing date and spacing. There were altogether 21 treatments comprising seven levels of sowing date viz. September 1, September 15, October 1, October 15, October 30, November 15, November 30 and three levels of spacing viz. 50x50 cm, 50x40 cm, 50x30 cm. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. Data were recorded on various parameters and statistically analyzed. The results of the experiment demonstrated that the majority of growth parameters and yield components v/ere significantly increased at the earlier sowing (October 1 ). The plant spacing had significant variation in almost all the growth and yield components except pericarp thickness. Number of branches per plant, number of leaves per plant, stem girth, number of fruits per plant, days to first harvest, fruit length, individual fruit weight, yield per plant were found to be significantly increased with the increasing of plant spacing but plant height at different stages, number of fruits per plot, days to 50% flowering, fruit breadth, yield per plot and yield per hectare were found to be significantly increased with the decreasing plant spacing. The combined effect of sowing date and plant spacing also had significant effect on different growth and yield parameter and yield. The highest yield ( 19.36 t/ha) of fruit was recorded from the earlier sowing (October 1) with the closest spacing (50x30 cm) which also gave the highest benefit cost ratio (4.58). Considering the yield of fruits per hectare, cost of production and net return, the treatment combinations of October I sowing along with 50x30cm spacing appeared to be recommendable for the cultivation of sweet pepper.
