Abstract/ Executive Summary:

The trial was carried out at the TCRC, BARI, Gazipur during 2001-2002.There was on significant interaction between varieties and different concentration of ethrel in respect of length of main vine, weight of vine per plant, weight of tubers per plant, tuber length and tuber yield per hectare . But the number of tubers per plant, individual tuber weight and tuber girth were significantly influenced by different treatment combinations. Insignificant variation in the yield indicated that the variety and the different concentrations of ethrel acted independently on each other. However, the highest yield was obtained by ethrel at 500ppm in both the varieties. The study needs further investigation for confirmation of the findings.

Keywords: Growth regulator, Yield, Sweet potato.

Location: Joydebpur, Gazipur.

Start Date: 09-12-2001

End Date: 05-05-2002

Program Area: Crop-Soil-Water Management

Commodity: Sweet potato

Objectives:

To investigate and determine the effect of growth regulator on the growth and yield of sweet potato

Methodology:

The trial was carried out at the TCRC, BARI, Gazipur during 2001-2002. There were two varieties of sweet potato viz. BAR SP-4 and BARI SP-5 and five levels of ether viz. (control), 250, 500 1000 and 2000 ppm. The trial was laid out in a randomized complete block design in a factorial experiment. The plot size was 3.0 × 2.4 m each accommodating 40 plants in four rows at 60× 30 cm spacing. The crop was fertilized at the rate of 10 tones of cow dung, 135 kg of urea, 90 kg of TSP and 135 kg of MP per hectare. Foliar spray of ethrel was applied at fortnightly intervals commencing after 45 DAP. The trial was set up on December 9, 2001 and harvested on May 5, 2002. Data was recorded form 10 randomly selected plants.

Achievement/Findings:

There was on significant interaction between varieties and different concentration of ethrel in respect of length of main vine, weight of vine per plant, weight of tubers per plant, tuber length and tuber yield per hectare. But the number of tubers per plant, individual tuber weight and tuber girth were significantly influenced by different treatment combinations. Insignificant variation in the yield indicated that the variety and the different concentrations of ethrel acted independently on each other. However, the highest yield was obtained by ethrel at 500ppm in both the varieties. The study needs further investigation for confirmation of the findings.
