To study the effect of different growth regulators at various concentration on fruit drop control in mango cv. Lagra


Author(s): Surjeet Pandey, Madhuri Garg and Dr. SS Singh

Abstract: Mango (Mangifera indica L.) is the most important among the tropical fruits of India. It is the premier and choice fruit of India and undoubtedly is one of the best fruits of the world. Mango occupies a pre-eminent place amongst the fruit crops grown in India and is acknowledged as the king of the fruit of the country. The Langra, also known as Banarasi Langra, is a mango cultivar primarily grown in Banaras, Northern India, Bangladesh and Pakistan. This cultivar retains a greenish tinge while ripening. It is normally harvested during the last half of July. Around 2006, it was known to be gaining popularity on the international market. It is considered suitable for slicing and canning. Fruit drop is the serious problem of central and north India. There is a lot of problematic factor for fruit drop like low stigmatic receptivity, defective perfect flowers (having defective embryo sac development at anthesis), poor pollen transference, occurrence and extent of self-incompatibility, competition between developing fruitlets and drought or lack of irrigation and incidence of insect pest and diseases. NAA is a plant growth regulator. The effect of growth regulator i.e. naphthalene acetic acid (NAA) on fruit drop, yield and quality in mango, cultivar 'Langra' was studied. Full grown mango plants were sprayed with 10, 20, 30 and 40 ppm NAA at different stages of fruit development. It shows the positive response to all yield attribute. 2,4-D is a also plant growth regulator and also applied in 5, 10, 15 and 20 ppm.3rd plant growth is taken GA3 with 50, 100, 150 and 200 ppm. And the result shows that the NAA is most suitable for yield attribution.
