Abstract/ Executive Summary:

An experiment has been carried out at the organic block of Olericulture Division under HRC, BARI to find the suitable F1 genotypes of virus-resistant summer tomato during May 2016 to October 2016has been developing by matured cowdung compost 15 t/ha/year. Five lines, CLN-3324A x CLN-3241AA, CLN-3324A x CLN-3125-O-19, CLN-3150-A-5 x CLN-3125-O-19, including two released varieties BARI hybrid tomato 4 and 8 were evaluated by applying hormone and without hormone. RCB design was followed with three replications. All treatment combinations were varied significantly. It was observed that application of hormone influenced the yield contributing characters, and quality of summer tomato genotypes. However, further study is required to confirm the results.

Start Date: 00-00-2016

End Date: 00-00-2017

Program Area: Crop-Soil-Water Management

Commodity: Tomato, Organic fertilizer

Objectives:

To test under organic practices, and hormone was applied to increase the yield and quality of summer tomato.

Methodology:

An experiment has been carried out at organic block of Olericulture Division under HRC, BARI has been developing by matured cowdung compost 15 t/ha/year to find the suitable F1 genotypes of summer tomato during May 2016 to October 2016. Five lines, CLN-3324A x CLN-3241AA, CLN-3324A x CLN-3125-O-19, CLN-3150-A-5 x CLN-3125-O-19, including two released varieties BARI hybrid tomato 4 and 8 were evaluated by applying hormone and without hormone. RCB design was followed with three replications. Tomato seeds were sown in an organic seedbed on 10 May 2016. At two true leaves seedlings were double transplanted in another organic seedbed, and 21 days old seedlings were planted on 5 June 2016 in the organic field developing by applying matured compost 15 t/ha /year. Before, ploughing the half amount of fully matured compost was applied and ploughing by a Power tiller and leveled. Then the 2.3 m tunnel was constructed apart from 70 cm drain surrounded. two beds 1 m in width were made apart 30 cm drain The beds then made furrow by spade and applied half of remaining half amount of compost. Finally, pits were dug by 50 cm x 50 cm and then applied the last amount of poultry compost and 100 g BAOFER in each pit followed by watering. In the afternoon, seedlings were transplanted. Tomato plants were stalked by a bamboo stick in a way of “A” shape. De-suckering and other intercultural operations were carried out as and when needed. Any pest management measurements except trap/barrier crop were taken in the study. Qualitative and quantitative horticultural traits data were recorded and here quantitative data are shown. Data were analyzed statistically using STAR software.

Achievement/Findings:

Fruit setting percent increase by the hormone in all varieties. Brix value showed mysterious results in the different genotypes two genotypes showed increased other three decreased. However, further study is required to confirm the results.
