Abstract/ Executive Summary:

The study was carried out in the field of Olericulture Division, Horticulture Research Centre, Bangladesh Agricultural Research Institute, Joydebpur. Two summer tomato hybrids were tested against net and open field condition during summer season of 2011. Net protection had significant influence on summer tomato production. Plants grown under net protection condition produced significantly higher number of fruits per plant (26.78) compared to that of open field condition (21.13). Fruit yield per plant was also higher in net protected plants (1.22 kg) and only 0.85 kg per plant when grown under open condition. Plants grown in open field were more than 40% plants were infected with TYLCV in open field while it was only 1.5% in net protected condition.

Keywords: Summer tomato, Netting, Virus, Yield

Location: The experimental field of Olericulture Division, HRC, BARI, Gazipur

Start Date: 30-05-2011

End Date: 00-09-2011

Program Area: Pest Management

Commodity: Tomato

Objectives:

To observe the effect of net protection on summer tomato production.

Methodology:

The experiment was conducted at the experimental field of Olericulture Division, HRC, BARI, Gazipur during the summer season of 2011. The experiment was conducted in RCB design in which two tomato varieties were grown in open and net protected condition. The seeds of BARI hybrid tomato-3 and BARI hybrid tomato-4 were sown in two separate seed bed on May 30, 2011. One seedbed was covered with nylon net while other seed bed remained open. Seedlings were transplanted in the main field on June 29, 2011. Under net protection condition the whole bed was covered with white nylon net (60 mesh) to protect the crop from white fly infestation. The unit plot size was 3.6 m x 2.3 m accommodating 24 plants in each plot having 60 cm x 40 cm plant spacing. The crop was fertilized with cow dung 10 ton, urea 550 kg, TSP 450 kg and MP 250 kg per ha, respectively. Half of the quantity of cowdung, entire TSP and half of the MP were applied during land preparation. The remaining half of the cowdung was applied during pit preparation. The rest of MP and entire urea were applied in three equal installments at 15, 30 and 45 days after transplanting. Irrigation, pruning, mulching weeding and other intercultural operations were done as and when necessary. No insecticidal spray was made in the present study. Data were recorded for some yield and yield contributing characters. Per plant yield was converted from plot yield. The recorded data under the present study were statistically analyzed using MSTAT programme. The level of significance and analysis of variance along with the Duncans Multiple Range Test (DMRT) Test.

Achievement/Findings:

Plants grown under net protection condition produced significantly higher number of fruits per plant (26.78) compared to that of open field condition (21.13). Fruit yield per plant was also higher in net protection plants (1.22 kg) and only 0.85 kg per plant when grown under open condition. Virus infection was also less in net protected field.
