## ANSWER

THE MINISTER OF STATE FOR AGRICULTURE AND FARMERS WELFARE कृ ͪष एवं ͩकसान कãयाण राÏय मंğी (SHRI RAMNATH THAKUR)

(a) & (b): The mango cultivation in the entire country is not affected by the problem of biennial  (alternate)  bearing.  It  is  found  in  patches  of  North  India  and  has  less  impact  in South  India.  Scientific  studies  on  biennial  bearing  in  mango,  including  its  causes  and regional impacts, have been conducted by Indian Council of Agricultural Research (ICAR) institutes  like  ICAR-Indian  Agricultural  Research  Institute  (IARI),  New  Delhi,  ICAR-Indian Institute of Horticultural Research  (IIHR), Bengaluru and ICAR-Central Institute for Subtropical  Horticulture  (CISH),  Lucknow.  The  studies  indicate  that  varieties  such  as Dashehari, Langra, Chausa, Fazli and Alphonso are predominantly biennial bearing in habit. The  main  causes  of  the  biennial  bearing  is  attributed  to,  inherited  physiological  trait influenced  by  genetic  factors,  nitrogen  and  carbon  reserves,  hormonal  control  of  flower formation, climatological factors, cultural practices and crop load.

(c): Various steps have been taken by ICAR to address the problem of biennial bearing in  mango. These include development through breeding and promotion of regular-bearing mango varieties and hybrids such as Amrapali, Mallika, Pusa Arunima, Pusa Lalima, Pusa Pratibha, Pusa Shreshtha, Pusa Manohari, Arka Udaya, Arka Suprabhat, Awadh Abhaya,

CISH-Arunika, CISH-Ambika, Awadh  Samriddhi, Neelam, Totapuri, Banganpalli and Sonpari  etc.  The  dissemination  of  quality  planting  material  of  these  varieties/  hybrids  to farmers  is  done  through  ICAR  institutes  and  registered  nurseries.  Mission  for  Integrated Development of Horticulture has initiated Clean Plant Program for producing disease free quality  planting  material.  Other  Steps  include  development  and  promotion  of  improved horticultural  management  practices  such  as  canopy  management,  high-density  planting, balanced nutrient and water management, climate resilient technology like pruning coupled with application of Nanoflorin to induce regular flowering and application of Paclobutrazol at the pea stage to induce new shoots for supporting fruiting in the next season.
