Abstract/ Executive Summary:

The study was conducted with four ash gourd lines at the research field of Olericulture division of HRC, BARI, Gazipur during summer season of 2016-17 to assess yield potentiality and adaptability. The days to 1^st female flower opening earlier in the line BH001 (36.80 days) followed by BH002 (37.33 days), while late in BH027 (42.03 days). Days to 1^st harvest was earlier in BARI Chalkumra 1 (50.13 days) followed by BH027 (51.20 days) and BH 0027 (52.10 days) and late in BH029 (54.58 days). The number of fruits/plant was highest in BARI Chalkumra 1 (8.9) followed by BH001 (8.0) and lowest in BH027 (6.35). Individual fruit weight was higher in BH001 (1.75 kg) and followed by BH029 (1.68) and lower in BARI Chalkumra 1 (1.45 kg). Fruit length was highest in BARI Chalkumra 1 (21.25 cm) followed by BH001 (18.75 cm) and BH029 (18.35 cm) lowest in BH027 (16.98 cm). Fruit diameter was highest in BARI Chalkumra 1 (9.9 cm) followed by BH029 (8.72 cm) and lowest in BH027 (6.67 cm). The yield per plant was higher in BH001 (14.0 kg) followed by BH029 (13.24 kg) and lowest in BH027 (10.15 kg). Among the advanced line yield/t/ha was highest in BH001 (46.23 t/ha) followed by BH029 (43.67 t/ha) and lowest in BH027 (33.49 t/ha).

Keywords: Yield, Ash gourd, Adaptability, Regional yield trial

Location: Olericulture division of HRC, BARI, Joydebpur, Gazipur Bangladesh

Start Date: 00-00-2016

End Date: 00-00-2017

Program Area: Crop-Soil-Water Management

Commodity: Ash gourd

Objectives:

To find out high yielding having attractive quality of ash gourd variety.

Methodology:

The experiment was conducted at the farm of Olericulture Division, HRC, BARI, Gazipur, during the summer season of 2016. The seeds of 4 advanced ash gourd lines were sown in the polybag on 20 April, 2016 and the 15 days old seedlings were transplanted in the main field on 05 May, 2016. The experiment was laid out in RCBD design with four replications. The unit plot size was 2 m x 7.5 m maintaining 2.0 m x 1.5 m spacing the land was fertilized with cow dung, N, P, K, S and Zn @ 20000, 80.6, 35.0, 75.0, 16.0 and 4.3 kg/ha, respectively. The total amount of cow dung, P, S and Zn and 1/3^rd of each of N and K were applied during final land preparation in the pit. The rest of N and K were applied in four equal installments at 21, 35, 55 and 75 days after transplanting. The intercultural operation was done as and when needed. Data on days to 1^st male flower opening, days to 1^st female flower opening, node order of 1^st male flower opening, node order of 1^st female flower opening, days to 1^st harvest, fruits number per plant, single fruit weight (g), fruit length (cm), fruit diameter (cm), yield/plant (kg), and yield (ton/ha), fruit shape and fruit color were recorded from five randomly selected plants per entry per replication. The data on different characters was statistically analyzed and presented in tabular form in the next paragraph.
