Abstract/ Executive Summary:

A pot experiment was conducted at the research field of Olericulture Division, Horticulture Research Center, Bangladesh Agricultural Research Institute, Joydebpur, Gazipur during the Kharif season of 2017-18 to investigate the effect of salinity on different ridge gourd genotypes. Eight ridge gourd varieties / advanced line; BARI Jhinga-1 (RG-1), BARI Jhinga-2 (RG-2), P2 × P1 (RG-3), P2 × P6 (RG-4), P1-8 (RG-5), P2-1 (RG-6), P3-1(RG-7) and P7-7 (RG-8) were included in this study. After transplanting into 15-L pots containing coco-dust, the plants were exposed to 0 (control), 6 and 12 dS/m salinity stresses and continue up to 30 days. The results revealed that soil salinity had negative impact on the physiological as well as yield and yield contributing parameters in all ridge gourd genotypes. At control condition, the numbers of fruits/plant were higher in RG-2 and RG-7 while, at 6 dS/m salinity, RG-7 produced the highest number of fruits/plant and at the highest salinity, RG-5 produced the maximum number of fruits/plant followed by RG-1 and RG-2. Individual fruit weight (IFW) was the highest in RG-6 followed by RG-7 and RG-5 at moderate salinity but at higher salinity, IFW was the highest in RG-6, followed by RG-3 and RG-5. In case of fruits yield/plant, RG-7 produced the maximum yield at normal condition followed by RG-6 and RG-1. Similarly trend of fruit yield were recorded at 6 dS/m salinity stress. However, at 12 dS/m salinity, RG-5 produced the maximum yield, followed by RG-2. Based on most of the parameter studied, RG-7, RG-6 and RG-5 found to be tolerant at 6 dS/m salinity; while, only RG-5 found to be tolerant at 12 dS/m salinity stress.

Start Date: 00-00-2017

End Date: 00-00-2018

Program Area: Variety and Species

Commodity: Soil salinity, Ridge gourd

Objectives:

To screen out ridge gourd genotypes against salinity and to investigate the mechanism of salt tolerance.

Methodology:

The experiment was conducted at the Olericulture Division, Horticulture Research Center, Bangladesh Agricultural Research Institute, Joydebpur, Gazipur during the months of May 2017 to August 2017 following a completely randomized design with three replications for screening the salt tolerant ridge gourd varieties/lines. Seeds of 8 varieties/lines (2 varieties and 6 advance lines) were sown on plastic pots (3" dia) containing loamy soil and cowdung. When the seedlings were developed 2 true leaves (22 days after sowing), they were transplanted into 15-L plastic pot containing coco-dust and irrigated with fresh water. Application of specific salt concentration were done into pots according to the treatment (0, 6 and 12 dS/m) after 7 days of transplanting. The plants were irrigated at every 3^rd days and continue up to 30 days. Hogland nutrient solution was applied to the pots in every 7^th day. Salinity concentration in the pots was monitored by Soil Conductivity/Salinity Meter. Data were collected on vine length, the number of lateral vines, nodes and green leaves per plant, fresh and dry weight of vine and root, SPAD value, number of fruit/plant, individual fruit weight and yield/plant. Collected data were statistically analyzed using XLSTAT 2015 software.

Achievement/Findings:

Based on higher number of leaves per plant at 60 DAT, lower number of damaged leaves per plant at 45 DAT, improved length, fresh and dry weight of vine and yield and yield contributing parameters, the lines P3-1, P2-1 and P1-8 found to be tolerant at 6 dS/m salinity while only P1-8 found to be tolerant at 12 dS/m salinity stress. However; the experiment may be repeated in the following year for more confirmation.
