EFFECT OF NITROBENZENE ON GROWTH AND YIELD OF BOTTLE GOURD (Lagenaria siceraria L.)
(DEPARTMENT OF HORTICULTURE, 2019) SAMAD, MD. ABDUS
The experiment was conducted in the Horticultural Farm of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh. The experiment consisted of two factors. Factor A: Different concentrations of nitrobenzene as C II 0 = Control (Water only), C = Nitrobenzene @ 2 ml/L, C 2 = Nitrobenzene @ 3 ml/L and Factor B: N = One spray, N 2 = Two spray, N = Three spray in the growing period. The experiment was laid out in a Randomized Complete Block Design with three replications. In case of different concentrations of nitrobenzene the maximum number of flower (male 51.06 and female 40.18), the highest number of fruit harvested per plant (10.95) and the highest yield (55.69 t/ha) were found from C 3 1 1 treatment, whereas the lowest from C treatment. For number of spray the highest number of flower (male 49.02 and female 38.05), the maximum number of fruit per plant (10.32) and the highest yield (52.94 t/ha) were recorded from N 3 treatment, while the minimum were from N treatment. Due to combined effect, the maximum number of flower (male 57.78 and female 47.12), the maximum number of fruit harvested per plant (12.55), the highest yield (63.38 t/ha) with net income (Tk. 587384.7) and BCR (2.23) were observed from C 1 N 3 treatment combination, while the lowest were from C So, economic analysis revealed that the C 1 N 3 0 N 1 1 treatment combination. treatment combination appeared to be the best for achieving the higher growth, yield and economic benefit of bottle gourd.
EFFECT OF STEM PRUNING ON YIELD AND YIELD CONTRIBUTING CHARACTERS OF CHERRY TOMATO IN SOILLESS CULTURE
(DEPARTMENT OF HORTICULTURE, 2021) SAMAD, MD. ABDUS
A pot experiment was conducted in the semi-greenhouse at the Horticulture Farm of Sher-e- Bangla Agricultural University, Dhaka 1207, Bangladesh, during October 2019 to March 2020 to investigate the effect of stem pruning on yield and yield contributing characters of cherry tomato in soilless culture . The experiment consisted of three level of pruning viz. P ii 0 = No pruning; P = One stem pruning and P 2 = Two stem pruning and four different cherry tomato varieties viz. V = BARI Tomato-11; V 2 = BARI Tomato-20; V 3 = Red Star and V = SAU Tomato-2. There were 12 treatment combinations and experiment were setup in Completely Randomized Design (CRD) with three replications. In case of pruning, the highest plant height, maximum branch number per plant, maximum chlorophyll content, minimum days required for first flowering and first fruiting, maximum flower cluster per plant, maximum fruit number per plant, highest single fruit weight (9.31 4 g), highest amount of TSS (9.46 degrees Brix) and yield per plant (2.37 kg) were obtained from P treatment at 60 DAT. Similarly, in case of varieties, the highest plant height , maximum branch number per plant, maximum chlorophyll content, minimum days required for first flowering and first fruiting, maximum flower cluster per plant, maximum fruit number per plant, highest single fruit weight (8.50 g), highest amount of TSS (8.92 degrees Brix) and yield per plant (2.63 kg) were obtained from V treatment at 60 DAT. In combined effect, the highest plant height , maximum branch number per plant, maximum chlorophyll content, minimum days required for first flowering and first fruiting, maximum flower cluster per plant, maximum fruit number per plant, highest single 2 fruit weight (12.42 g), highest amount of TSS (10.53 degrees Brix ) and yield per plant (2.98 kg) were obtained from V 2 P 2 treatment. Among the treatment combination, V 2 P (BARI Tomato-20 variety with two stem pruning) treatment seemed to be more promising for obtaining the maximum yield of cherry tomato.
