The Three-hundred-variety mango of Malihabad
Another reflection on a remarkable Indian mango tree from our friend Bhuwon Sthapit of Bioversity International.
It is hard to believe that a farmer can have as a hobby the grafting of multiple varietal scions of interesting and unique mango diversity on to a single tree. I certainly did not believe it. Until I saw the orchard of Haji Kaleem Ullaj Khan in Malihabad. There he maintains several trees with many varieties grafted onto them as sources of scions for his mango nurseries. A good and reliable source of scions is essential to run a successful and credible mango nursery, but to have a conventional scion block is expensive in terms of maintenance and land.
The son of the magician grafter, Najmi, showed me two very remarkable mango trees. One is said to be 100 years old and is named Al-Muqarrar. It has had more than 300 varieties of mango skilfully grafted onto it by Najmi’s father father. The other, younger tree has more than 150 mango genotypes grafted on to it. Each branch looks like a different tree! Both trees are bearing fruits of different colour, shape and size, and at different times.
Born in 1945, Haji Kaleem Ullaj Khan does not have any academic horticultural degrees, but he is widely renowned in India for his skills and knowledge in multiple grafting on a single tree. He was awarded the title of Udhyan Pandit (Professor of the Orchard) by a former President of India. He has also presented a mango tree bearing 54 varieties to the current President for the premises of the Mughal Garden of Rastrapati Bhavan. He has been acknowledged by many high-profile visitors from abroad and also decorated with the Padamashri award. His name is recorded in the Guinness Book of World Records for his grafting feats.
Abdullah Nursery is famous in Malihabad and throughout India for Haji Kaleem Ullaj Khan’s innovations, and markets saplings of commercial varieties to such distant places of Bhutan, Nepal and Bangladesh. Unlike government research stations, Haji Kaleem Ullaj Khan uses ground layering for his propagation for most commercial saplings, and veneer or wedge grafting in special cases. He has also grafted a guava tree that flowers and fruits all year round, which is another attraction for the nursery.
This innovation borne out of local need is a promising way for nurseries to maintain many scions at relatively low cost. However, this can be a high risk practice, because many varieties depend on one mother tree’s survival. It is thus important to have adequate safety duplication or maintain some scion material trees separately. Multiple variety grafting can also be used as an attraction in agrotourism, and for innovative marketing of diversity in urban and home gardens. This will create a new market for nursery growers and raise public interest in the diversity of mangoes. This activity has been conceptualized in the context of the UNEP/GEF project Conservation and Sustainable Use of Tropical Fruit Tree Diversity in India.
Clean water and indigenous knowledge
SciDev.net reports that prickly pear cactus (Opuntia spp) can be used in a simple process to remove 98% of bacteria from dirty water. ((I worry about the other 2%, really I do.)) That would be good news for poor people who may be surrounded by prickly pears, but lack clean water. Alas, (some) poor people don’t want pure water.
“Stomach and intestinal infections are considered a way of cleansing the body, and are not conceived as diseases.”
Oh the dilemma. Preserve their indigenous knowledge, or offer them better health? ((Yeah, yeah, another damned binary choice, I know.))
Strangely, among other communities, on another continent, indigenous knowledge of the water purifying properties of Moringa seeds is just plain confused. Some people know all about it, others believe that more than three Moringa trees are “a source of misfortune that brings poverty and death”. But not from water-borne diseases, perhaps.
Bob is healthy
Via Lois Englberger comes news of Bob Festival Day in the Marshall Islands last Saturday, 24 April. Bob is not some guy, but rather the Pandanus tree. Lois shared Lydia Tibon’s description of the event, which we reproduce below. Pandanus is very important throughout the Pacific, where it has multiple uses. Lois is particularly interested in its beta carotene content. Our thanks to both her and Lydia.
KIJLE (Kora in Jiban Lolorjake Ejmour), meaning “women assisting to promote good health,” participated. We wanted to remind everyone that Bob is better than eating processed foods.
As you can see, the table, chairs, everything hanging and inside our float were pandanus-made. Our kids, grannies were chewing and throwing bobs to everyone. Our billboard message was to promote both education and health.
Our motto is Bob Dikdik Kejadikdrik, the translation is something like “Bob is so fruitful.” It produces so much, it gives us so much knowledge that we use the leaves by weaving the mats, making hats, use to drink medicines, also gives Vitamin A that is very rich to protect our skin, vision, bones and many more….
Our T/shirt that day was “Bob is healthy.”
The birthplace of the Dashehari mango
Our dear friend and colleague Bhuwon Sthapit has prepared this post for us with input from Dr H. Ravishankar, Dr BMC Reddy, Dr S Rajan and farming communities. Thanks, everyone!
‘Dashehari’ is one of the most popular mango varieties of North India, widely acclaimed for its exquisite taste and pleasant aroma. It is also my favorite. Naturally, I was excited to visit the Dashehari Village in Malihabad where the 200 years-old mother tree of the variety, a cultural heritage of the community, still lives.
It is believed that the trees on 80% of the area covered by mango in northern India can be genetically traced back to this very tree. The heritage is exciting, but the risks resulting from massive uniformity of orchards and lack of home gardens to harbour other interesting types of mangoes are terrifying.
Legend has it that a Pathan of Khalispur village of Malihabad Tehsil, transporting choicest mangoes for trade, happened to halt for rest in a hut of a poor Momedian, a monk. The Momedian helped travelers by offering water and shelter and the travelers reciprocated with ripe mangoes.
At the time of departure, the Pathan and the monk had an argument. In a fit of rage, the Pathan shoved one of his choicest ripe mangoes into the soil instead of gifting it to the monk, who however maintained the utmost calm and restraint. In the ensuing rainy season, a mango sapling emerged from the spot, which was duly nurtured to a robust tree by the Momedian. After about twelve years, the tree profusely flowered and yielded fruits of excellent quality.
The news of this unique mango reached the Nawab who owned the land. Being aware of the importance of genetic wealth, he took due care to protect and conserve this exquisite mango variety, which later became the popular ‘Dashehari’ variety of North India.
The tree is still very healthy and impressive, about 10m tall, having a mean canopy spread of 21.0 m and a trunk circumference of about 3.0 m (see picture 1).
The tree has a robust trunk with twelve main scaffolding branches originating and radiating at 1.5 m height almost parallel to the ground.
The tree has spreading canopy architecture with impressive fruiting at the time of the visit, completely overshadowing neighboring trees.
A scientist from the Central Institute of Sub-tropical Horticulture in Lucknow told me that fruits of this Dashehari tree are oblong, elliptical and medium size (13cm long and 8 cm breadth) weighing 130 to 260 g.
It has attractive yellow pulp, firm and non-fibrous, with very sweet taste (researchers told me that it has oBrix score of 21-23 as measure of sweetness in fruits) and pleasant aroma. CISH collected scion material of the tree for clonal propagation in 1977 and thereafter elite clones spread to northern Indian farmers from a network of private and government nurseries.
This cultural heritage tree belonged to the great-grandfather (Mr Ishtida Hussain) of farmer Mr Shamir Zaidi, now 30 years old, who has named his house in honour of the variety — Dashehari Kothi. Mr Kamil Khan, an 87 years old but rather progressive orchardist of the small hamlet of Kakori (close to Dusseheri village) of Malihabad Tehsil shared local legends with the visitors. He told us that the tree, under natural care, is free from stemborer and termites attacks, both common problems of mangoes. It is also free from Loranthus infestation. This tree has yielded on an average 80-190 kg in the last eight years, with a moderate biennial bearing habit.
In September 2009 the area was registered with Geographical Indication No 125 in the name of “Mango Malihabad Dusseheri” by India’s Geographical Indication Registry. The communities around the mother tree have also been selected for the UNEP/GEF Project “Conservation and sustainable use of wild and cultivated fruit tree diversity: Prompting sustainable livelihoods, food security and ecosystems services” in Malihabad, Lucknow. Communties such as Sarsanda, Kasmandi Kalam and Mohammad Nagar Talukedari have 7-29 cultivated varieties each.
They are also blessed by rich diversity in seedling mango trees, with an estimated population of 3000 to 5000 mango seedling trees. Almost all current commercial mango varieties in India are selected from the seedling population. Potentially research can identify many more consumer- and farmer- preferred diversity of mangoes and innovative farmers can work together with researchers and nurserymen to identify, select and popularize the elite materials from existing farmer’s orchards. The project aims to empower farming communities and local institutions to identify unique varieties from the orchards and scale up genetic resources and associated traditional knowledge for sharing wider benefits to farmers and consumers.
Almost all orchards in Malihabad are dominated by Dashehari (80%), with over 10-20 varieties of other cultivated types, but few trees of each. Around the orchards farmer maintain many seedling types and all of these trees produce diverse fruits with diverse shape, size, color and taste. There is thus scope to increase diversity in the market by sharing information with consumers in urban areas to stimulate demand for other varieties there, and thus minimize the risks posed by uniformity while also providing livelihood security for mango growers.
