Abstract/ Executive Summary:

The experiment was conducted at TCRC, Joydebpur, Gazipur during 2008-09 to find out the b time of harvest for getting desirable yield of promising potato varieties. Four harvesting was done at 10 days interval started from 60 DAP and continued up to 90 DAP. Three promising variety and two hybrid clones include in the study. Some growth and yield contributing characters varied significantly in all the cases. Number and weight of tuber, tuber yield and dry matter percent increased up to 80 DAP in all the variety/hybrid clones. The highest number of weight and tuber yield was recorded in Meridian when harvested at 80 DAP. The lowest number of tuber was obtained in Sassy 60 DAP where as the lowest weight of tuber and tuber yield was in 1.25 60 DAP. Dry matter percent and tuber grading varied significantly.

Keywords: Bulking Behaviour, Promising Potato, Gerplasm

Location: Joydebpur, Gazipur

Start Date: 21-11-2008

End Date: 21-02-2009

Program Area: Variety and Species

Commodity: Potato

Objectives:

i) To know the bulking behaviour of promising potato varieties

ii) To identify early varieties

iii) To find out optimum time of harvesting for maximum production of large tubers required for processing.

Methodology:

The experiment was conducted at TCRC, Joydebpur, Gazipur in the growing season 2008-09. The treatment of the experiments consisted of five variety/clones viz. Almera, Meridian, Sassy, 1.25 and V4 and four harvesting time viz. 60, 70, 80 and 90 DAP (Days after Planting). The two factor experiment was set in RCBD with 3 replications. The whole tuber of all varieties or germplasm planted on November 21, 2008. The unit plot size was 1.8 m x 3m with spacing of 60 x 30 cm. Harvesting was done according two factor B (harvesting time). Fertilizers, irrigation and necessary intercultural operations were done as per TCRC recommendation. Data on different growth, yield and yield contributing characters were recorded and were analyzed statistically and means were separated by DMRT.

Achievement/Findings:

Some growth and yield contributing characters varied significantly in all the cases. Number and weight of tuber, tuber yield and dry matter percent increased up to 80 DAP in all the variety/hybrid clones. The highest number of weight and tuber yield was recorded in Meridian when harvested at 80 DAP. The lowest number of tuber was obtained in Sassy 60 DAP where as the lowest weight of tuber and tuber yield was in 1.25 60 DAP. Dry matter percent and tuber grading varied significantly.
