Observational Yield Trial of Bitter Gourd for Summer Season

M.H. Al-Mamun

M.A.T. Masud

Abstract/ Executive Summary:

The study was conducted at the experimental field of Olericulture Division of HRC, BARI, Joydebpur to select superior lines of bitter gourd. Thirteen lines of bitter gourd were included in this study. The genotypes differed significantly for all the characters studied. Days to 1st harvest range from 74-38 days, fruits per plant 24.60-16.65, average fruit weight 132-54g, no. of fruit fly infested fruit 5.7-1.3 and yield per plant 0.8-3.25 kg. Considering earliness, high yield, fruit color and acceptable fruit size, shape, fruit fly infestation, 6 lines MC 107(A)-3, MC 106-1, MC 104-1,MC 105-8, MC 104-4 and MC 101-3 were selected for further evaluation.

Keywords: Observational yield trial, Bitter gourd, Yield performance

Location: Farm of Olericulture Division, HRC, BARI, Gazipur

Start Date: 20-03-2013

End Date:

Program Area: Variety and Species

Commodity: Bitter gourd

Objectives:

To select superior lines of bitter gourd.

Methodology:

The experiment was conducted at the farm of Olericulture Division, HRC, BARI, Gazipur during the summer season of 2013. The seeds of 13 bitter gourd lines were sown in the poly bag on 20 March 2013 and seedlings were transplanted in the main field on 25 April 2013. The experiment was laid out in RCB design with two replications. The unit plot size was 7.5 x 1.2 m maintaining 50 cm drain and 1.5 m (plant to plant) spacing. The land was fertilized with cow dung, urea, TSP, MP, gypsum and zinc oxide @ 10,000, 175, 175, 150, 100 and 12 kg/ha, respectively. The total amount of cow dung, TSP, gypsum, zinc oxide and 1/3rd of each of urea and MP were applied in pit. The rest of MP was applied in two equal installments at 10 and 20 days after transplanting. Urea was applied in four equal installments at 21, 35, 55 and 75 days after transplanting. The intercultural operations and plant protection measures were done as and when needed. Data on days to 1st harvest, marketable fruits per plant, single fruit wt.(g), fruit length (cm), fruit diameter (cm) and yield per plant (kg) were recorded from three randomly selected plants per replication. The data were statistically analyzed with MSTAT.
