Some aspects of weather dynamics influencing production and sustainability of mango (Mangifera indica L.) in Malihabad belt of Uttar Pradesh

A weather dynamics appraisal at the Malihabad farm and regional scale during 2010-11 clearly indicated overall detrimental impacts on Dashehari mango fruit production. The appraisal of key weather parameters with potential to impact mango crop phenology viz., temperature, rainfall, relative humidity, bright sunshine hours, wind speed, open pan evaporation indicated their possible influence. Conducive temperatures (Tmin) prevailed favouring FBD in the region leading to satisfactorily flowering in different mango varieties during February 2011. Sudden increase in temperature (Tmax and Tmin) couples with reduction in RH and concomitant increase in bright sunshine hours, wind speed and pan evaporation during the post flowering period severely impacted fruit set, nubbin fruit formation, fruit drop, fruit growth and development and incidence of pest and diseases. Advancement, delay, multiple flushes of flowering coupled with changes in flowering and fruiting pattern, fruit development and maturity periods in mango, is becoming worrisome for growers in recent years.Sudden rise in temperature above 350C during March-April coupled with high wind velocity and low relative humidity may cause severe damage to the panicles; sometimes heat injury due to dehydration or embryo abortion leading to nubbin fruit formation, causing drop in fruit yields. The agro-climate analysis would empower the farmers to adopt effective orchard management practices that minimize the adverse effects of weather dynamics.
