Abstract/ Executive Summary:

A multi-location trial conducted at 6 locations with 4 selected indigenous potato varieties (IPV) demonstrated a high yield potential of the selected IPVs when high quality seed potatoes and optimal levels of production inputs were used. The trial was conducted during the 2013-14 season, and the locations were, Hajee Danesh Sc & Tech University, Burirhat ARS, Rangpur ARS, Hathazari RARS, Shibgang and Gouripur. The selected IPVs used in the trial were, Pakri-1, Pakri-2, Ausha-1 and Dohazari-1. The variety Pakri-1 was recorded to be the highest yielder of potatoes, giving an average yield of 32.7 Mt/ha; which was about 2.9 times than the national average yield of IPV. Use of high quality seed potatoes, produced through positive selection, was recognized to be an important reason for getting a very high yield of potatoes in the trial. Organized production and supply of high quality seed potatoes of selected IPVs would ensure effective improvement and extension of IPV production in targeted areas of the country.

Keywords: Yield and yield components, Indigenous Potato Varieties, Multi-location Trial, Performance

Location: Hajee Md. Danesh Sc. & Tech. University (USTU),Dinajpur; Burirhat, Rangpur; Alamnagar, Rangpur; Hathazari, Chittagong; Shibganj, Bogra and Gouripur, Mymensingh.

Start Date: 00-00-2013

End Date: 00-00-2014

Program Area: Crop-Soil-Water Management

Commodity: Potato

Objectives:

i. To assess the growth and development of the selected 4 IPVs at 6 trial locations.

ii. To assess the yield of the selected 4 IPVs at 6 trial locations.

iii. To assess the genotype-environment interaction of the selected 4 IPVs in relation to development of yield components and their contribution to yield.

Methodology:

The multi-location trial was conducted during the 2013-14 season at the following 6 locations : i. Hajee Md. Danesh Sc. & Tech. University (USTU), Dinajpur; ii. Burirhat Agri. Res. Station, Burirhat, Rangpur; iii. Rangpur Agri. Res. Station, Alamnagar, Rangpur; iv. Hathazari Reg. Agri. Res. Station, Hathazari, Chittagong; v. Roynagar, Shibganj, Bogra; vi. Kaltapara, Gouripur, Mymensingh. The trials conducted at Shibganj and Gouripur upazillas were non-replicated, and those at other 4 locations were replicated. The unit plots of replicated trials were 3.6 m x 3.0 m in size; and those of non-replicated trials were 3.6 m x 6.0 m. Four selected IPVs, namely, Pakri-1, Pakri-2, Ausha-1 and Dohazari-1 were used for the replicated as well as non-replicated trials. Whole tubers were planted at a spacing of 60 cm x 15 cm; accommodating 120 hills in each of the unit plots of a replicated trial, and 240 hills in each of the unit plots of a non-replicated trial. Planting was done on 12 Nov at HSTU, Burirhat and Rangpur sites, on 17 Nov at Shibganj and Gouripur sites; and on 22 Nov 2013 at Hathazari site. Irrigation, weeding, earthing-up, spraying of insecticides and fungicides were done as per schedule/ as and when needed for the production of a table potato crop. Roguing and haulm pulling operations were not done. Replicated trials were conducted at 4 locations, namely, HSTU, Burirhat ARS, Rangpur ARS and Hathazari RARS. The trial, at each location, was set in RCBD with 3 replications. Data were collected, processed and analyzed as per standard procedure. Non-replicated trials were conducted at Shibganj of Bogra and Gouripur of Mymensingh. Data were collected and processed as per standard procedure.

Achievement/Findings:

i.The selected 4 IPVs gave much higher yields in the multi-location trial conducted in the year 2013-14, than the national average yield of IPV. The variety Pakri-1 gave the highest average yield (32.7 Mt/ha) in the trial, which was about 2.9 times higher than the national average yield of IPV. ii.The yields of the selected 4 IPVs were the lowest at Hathazari RARS site, and the low yields were particularly due to sub-optimal production environment of the trial site. Repetition of the trial in Chittagong region under optimal production environment is needed for a clear recommendation on IPV production in Chittagong region. iii.The use of high quality seed potatoes of selected IPVs, produced through positive selection, was recognized to be an important reason for getting high yield of potatoes in the trial. iv.Encouraging results of the multi-location trial suggest the need for setting demo trials on Pakri-1 variety of IPV in areas where there is a scope for improvement and extension of IPV. The areas should include Mymensingh, Sherpur, Jamalpur, Kishoreganj, Sylhet, Moulavibazar, Chittagong, Patuakhali, Barisal, Borguna and Bhola. v. Organized production and supply of high quality seed potatoes of selected IPVs will ensure effective improvement and extension of IPV production in the targeted areas of the country.
