A field experiment was carried out at the Horticultural farm of the Bangladesh Agricultural Research Institute (BARI), Joydebpur, Gazipur, during September 2006 to April 2007 to investigate growth and yield of sweet pepper as influenced by spacing. There were three levels of spacing viz. 50×50 cm, 50×40 cm, 50×30 cm. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. Data were recorded on various parameters and subjected to statistical analysis. 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. Considering the yield of fruits per hectare, cost of production and net return, 50×30cm spacing appeared to be recommendable for the cultivation of sweet pepper.

A pot experiment was conducted in the Net House of "Field Laboratory of Plant Stress Management" in the Horticulture farm of Sher-e-Bangla Agricultural University, Dhaka, during the period from October 2016 to March 2017. The two factors experiment was laid out in Complete Randomized Design with five replications. Factor A is three tomato varieties viz. V 1 = Exotic line 1 (Korean), V 2 = Exotic line 2 (Taiwan) and V 3 = BARI tomato 14 and factor B is seed priming treatment viz. P 0 = No priming (Control), P 1 = Hydropriming (distilled water), P 2 = NaCl priming (50 mM) and P 3 = KNO 3 priming (200 mM). The total treatment combinations were (4×3) 12 and 8 dS/m fixed salinity maintained for all the pots. The experimental results exhibited that seed priming treatment significantly affected growth, yield and quality parameters of tomato. The highest plant height (137.10 cm), number of fruits per plant (40.92) and fruit yield per plant (585.00 g) were found from V 1 under 8 dS/m salinity level. In case of seed priming, the highest plant height (150.10 cm), number of fruits per plant (48.11) and fruit yield per plant (755.80 g) were recorded from P 2 mostly at 8 dS/m salinity level. Regarding the combined effect, the highest plant height (187.00 cm), number of fruits per plant (55.00) and fruit yield per plant (829.30 g) were found from V 1 P 2 under 8 dS/m salinity level. So, Exotic line 1 with NaCl priming (50mM) showed better performance for growth, yield and quality of tomato under saline condition.

to add value to Watermelon rind and to study quality of watermelon rind jam as influenced by different concentration of rinds and sugar with flavors. This single factors experiment was consisted of sixteen treatments with three replications and laid out in CRD. The treatments were T 1 F 0 =50% rind+50% sugar+no flavor; T 1 F 1 =50% rind+50% sugar+strawberry flavor; T 1 F 2 =50% rind+50% sugar+pineapple flavor; T 1 F 3 =50% rind+50% sugar+vanila flavor; T 2 F 0 =80% rind+20% sugar+no flavor; T 2 F 1 =80% rind+20% sugar+strawberry flavor; T 2 F 2 =80% rind+20% sugar+pineapple flavor; T 2 F 3 =80% rind+20% sugar+vanila flavor; T 3 F 0 =60% rind+40% sugar+no flavor; T 3 F 1 =60% rind+40% sugar+strawberry flavor; T 3 F 2 =60% rind+40% sugar+pineapple flavor; T 3 F 3 =60% rind+40% sugar+vanila flavor; T 4 F 0 =40% rind+60% sugar+no flavor; T 4 F 1 =40% rind+60% sugar+strawberry flavor; T 4 F 2 =40% rind+60% sugar+pineapple flavor; T 4 F 3 =40% rind+60% sugar+vanila flavor. At first qualitative test was done for prepared jam. Then organolaptic test was done and last of all various chemical changes were determined with the storage period. T 1 F 1 was statistically best. The chemical analysis of T 1 F 1 jam was pH (3.80), TSS (6.00 %,), TA (2.48%), vitamin C (0.26mg/100g). This suggested that 50% rind+50% sugar and strawberry flavor was the promising formulation for the preparation of good quality of watermelon rind jam.

The experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, during the period from December 2017 to April 2018 to study the yield performance of some maize varieties as influenced by irrigation management at different growth stages. The experiment was laid out in a split plot design with three replications where factor (A) irrigation stages were allocated in main plots and factor (B) varieties were distributed in sub plots. In factor A five irrigation management viz. I0 = (No irrigation), I1= (Four leaf stage + eight leaf stage + tasselling stage+ grain filling stage), I2= (Four leaf stage+ eight leaf stage + tasselling stage), I3= (Eight leaf stage + tasselling stage +grain filling stage), I4=(Four leaf stage + tasselling stage+ grain filling stage), I5=(Four leaf stage+ eight leaf stage+ grain filling stage) and in factor B three varieties viz. V1= (BARI hybrid vutta-9), V2= (BARI hybrid vutta-13), V3= (pacific-559) were included as treatments in the experiment. Data were collected on yield and yield contributing characters. The highest grain yield (5.88 t/ha) was obtained with the water management treatment I1(Four leaf stage + eight leaf stage + tasselling stage+ grain filling stage) which is statistically similar to treatment I4(Four leaf stage + tasselling stage+ grain filling stage) and highest grain yield (5.87 t/ha) obtained due to the varietal factor V3 (pacific-559). Interaction between I1 irrigation treatment and V3 varietal factor (I1V3) were found to be the best combination which is statistically similar to I4V3 interaction. As I4 treatment and I4V3 interaction are cost effective than I1 treatment and I1V3 interaction, respectively, irrigation should be given at four leaf stage, tasselling stage, and grain filling stage with variety pacific-559 for better performance in maize production.
