The inter-specific attachment has emerged as a promising tool for increasing the tolerance to the organic phenomena and abiotic stresses, besides enhancing the productivity in vegetables. The twin or multiple attachments is a new technological possibility, wherein, 2 or over 2 scions of constant family area unit grafted along to reap over one vegetable from a single plant.
At ICAR, Indian Institute of Vegetable analysis, Varanasi, Uttar Pradesh after a successful field demonstration of Grafted Pomato (Potato + Tomato), the twin attachment of brinjal and Tomato (Brimato) was demonstrated within the field throughout 2020-21. The brinjal Hybrid – Kashi Sandesh and improved successfully of Tomato – Kashi Aman were with success grafted into mad apple rootstock – IC 111056.
The grafting Operation was carried out once eggplant seedlings were twenty-five to thirty days old and Tomato twenty-two to twenty-five days old. The eggplant Rootstock – IC 111056 contains a tendency to develop 2 branches in around five-hitter of seedlings. The grafting was done by the side/splice technique, wherein, five to seven-millimeter diagonal cuts (45° angle) were created each within the Rootstock and scion. Shortly after grafting, the seedlings were kept under controlled weather conditions, where the temperature, humidity, and light were unbroken at optimal for initial five to seven days, then in partial shade for another five to seven days.
The Grafted plants were transplanted within the field fifteen to eighteen days after the grafting operation. During the early growth stage, precaution was taken to keep up the balanced growth each in the eggplant bush and Tomato Scions. Also, shoots, if any arises below the grafting union, were removed right away. The fertilizers were applied at 150:60:100 kilo NPK/ha, apart from twenty-five Tonnes of FYM. Each eggplant and the tomato started to mature sixty to seventy days after planting.
The experimental findings discovered that about 36.0 fruits with 2.383 kg yields were harvested in Tomato/plant, whereas in eggplant bush two.684 kg yields were obtained from 9.2 Fruits/plant. The dual Grafted Brimato Technology would be very helpful for the urban and suburban areas, wherever the restricted areas are available for accommodating vegetables in a vertical garden or pot culture over the terrace and compound.
The analysis on commercial production of Grafted Brimato continued at the ICAR-IIVR, Varanasi, Uttar Pradesh.
