Lucknow :
It is believed that good things are difficult to get.
Perhaps that’s why every mango grower lives with the fact that his mango orchard will follow the accepted alternate bearing pattern. This pattern, common to mango and several other fruit crops, means that the yield of fruit will not be the same year after year. A heavy yield one year could be followed by a dismal one another year and vice versa.
However, if you pass through Kunwarpur village on Sitapur Road, there will be one mango orchard outshining all others. Here, unlike others, each tree is laden with the king of fruits, waiting to be plucked. This delighting yield is no freak of nature but a result of a well-researched technique and years of hard work.
City-based mango grower Kunwar Raghavendra Singh introduced the canopy management technique in his orchard over a decade ago.
Under this, trees are pruned regularly to turn the upper part of the tree to look like an inverted umbrella, instead of a canopy. Using this technique, Raghavendra has turned his barren land into a 100% productive mango orchard, producing varieties of mangoes including dussehri, langda and chausa.
Even when the weather was playing havoc with all kinds of crops and subsequently with the fate of farmers, Raghavendra was not worried.
His more than 3,500 mango trees were safe from the untimely rain and thunderstorms. “The most harmful factor for any mango tree is the canopy shape. It can have good flowering but not good fruiting. Apart from the fact that it hardly bears any fruit, this form limits the penetration of sunlight in the tree. This affects photosynthesis and the health of the tree,” says Raghavendra. The central shoots are the fastest growing in any tree and draw most of the nutrition and hormones. When the central shoots are removed, the nutrition flows side ways to lateral branches. This results in better size of the fruit, he explains.
Efforts must also be made to see that trees are gradually brought down to a maximum height of 22 feet-a manageable height which makes spraying pesticides easier, he adds.
Ready to extend a helping hand to other mango growers and also to the state horticulture department, Raghavendra claims that unlike a dense mango orchard, an open one reduces the cost of management and results in optimum flowering and fructification even in inclement weather.
The inverted umbrella structure allows free movement of air thus facilitating cross pollination. After untimely rain, the free movement of air helps evaporate moisture, the most devastating factor in the growth and spread of fungal infections.
Dr Mansoor Hasan, a city-based cardiologist, has also implemented this technique in his orchard in Manikpur, near Unchahar since 2011, with the help of his son Aly Hasan.
Happy with his produce, Dr Hasan says, “I have observed that fruits of a well-managed tree are also bigger in size and qualitatively better as compared to a taller tree. Even trees which were not giving any fruit for past many years have gradually started bearing fruit once they were pruned,” he adds.
In the case of mango trees, it seems, bigger is not better.
