TBI Blogs: How Growing Trees and Crops Together Is Helping Tamil Nadu’s Farmers Earn Better

Farmers in the southern reaches of Pudukottai district in Tamil Nadu have turned to agroforestry to protect and boost incomes, because falling groundwater levels and overuse of chemical fertilizers and pesticides has made agriculture unsustainable in the area. Jency Samuel takes a closer look.

“We have found our treasure in trees,” declares Ramanathan, a 70-year-old farmer of Pudukottai district in Tamil Nadu. Farmers in his locality have found prosperity in agroforestry, the practice of growing trees and crops in farmlands, instead of just cultivating crops. Agreeing with Ramanathan, Jesuraj shows his rice field, juxtaposed against a grove of coconut, banana, and jackfruit trees.

Pudukottai is considered a dry area. In spite of being close to the Cauvery delta, and in spite of Pudukottai’s Aranthangi taluk falling under the Cauvery delta, the district does not receive water from the river. Even as the delta farmers are financially distressed, reeling under a severe drought, the farmers in the southern taluks of Pudukottai district have not been affected. The farmers attribute their success to agroforestry, though they rely solely on deep borewells for irrigation.

From open wells to bore wells

Kaspar, a 42-year-old farmer of Kottai Kadu in Karamabakudi taluk, recalls his grandfather’s stories. “Water was available sometimes even at the depth of 10 feet, according to my grandfather. So they just dug up small ponds. When my father took up farming, he dug a 90-feet-deep keni (an open well),” Kaspar told VillageSquare.in.

Arokiasamy of Vanakkan Kadu village has started farming his ancestral lands after retiring from the state’s agriculture department. According to him, in the 1960s, water was available at a depth of 30 feet. Oxen were used to lift the water from open wells and irrigate the fields. Agricultural income, their sole earning, was limited. Senior citizen Chinnappa, of Pullan Viduthi village in Thiruvarankulam taluk, points out that the earlier generation of farmers such as his father and grandfather practised more subsistence farming.

Elderly farmers say that those were the mummaari days, when they had three rainy seasons in a year. Around the time the monsoons became irregular, the bore wells were introduced. Many farmers recall that bore wells were first sunk in their region in 1972.

Short-lived euphoria

Ramanathan recalls the initial days of euphoria. Suddenly there seemed to be plenty of water. Combined with the green revolution practices of using chemical fertilizers and pesticides, farmers enjoyed good farm income for the first time. However, their success was short-lived. After a decade, their expenditure on farm inputs increased. Beyond a point, the yield not only did not increase, but started decreasing.

Most of the farmers grew two crops. “My father grew pulses and paddy. He didn’t make any profit. He suffered a lot financially in the mid-80s,” recalls Kaspar. Ramanathan adds that those with more acreage grew more number of crops, such as groundnut, pigeon pea, and black gram. Yet, it was limited to two cropping seasons, and the farmers found it hard to make a living out of farming.

Foray into agroforestry

Sampath, from Keeramanagalam in Aranthangi taluk, is a graduate in agriculture science. He says that their ancestors had grown trees, but the later generation switched to mono-cropping. “We did have fruit trees in our farms earlier, but they were just a handful, and only for personal use,” Chinnappa told VillageSquare.in.

The present shift to agroforestry seems to have happened by chance. Ramanathan recalls an incident that led to the farmers slowly shifting from cultivating crops alone to agroforestry.

It was Thangasamy, popularly known as Maram Thangasamy (maram means tree in Tamil), of Senthankudi village, who showed the way. “We were part of a farmers’ federation. Once, Thangasamy dug a 100-feet well. But there was no water. He had already planted chillies in three acres. Unable to bear the plants wilting, he left the village. But after he came back, he started planting trees,” recalls Ramanathan.

Thangasamy was ridiculed by the villagers for using cropland for planting trees. “I too questioned his decision. He then told me that I’d be following his footsteps in five years,” Ramanathan told VillageSquare.in. Thangasamy’s words came true. Ramanathan was one of the first converts to agroforestry, followed by many villagers.

Systematic agroforestry practice

An unplanned agroforestry system does not work. The trick is to have a tiered tree planting plan, according to Ramanathan. “Teak can be used after 10 years, mahogany after 15 years. Include fruit trees such as mango, guava, gooseberry, and pomegranate that will give an annual yield. Also follow inter-cropping and multi-cropping,” he points out.

“When you plant, you leave a gap of 6 feet between tree saplings. For the next three years, before the saplings grow to full height, you can do inter-crop in the gap between the saplings. You can grow groundnut, sesame, pulses, or vegetables like tomato and okra in the gap. You will be able to harvest a minimum of five inter-crops in three years,” Ramanathan told VillageSquare.in.

This systematic approach has worked well for the farmers. Parimalam, a diploma holder in electronic engineering, quit his job and got back to farming. He earns ₹5-6 lakh per year, way more than what his job paid. “I have eight acres. In one portion, I have red sanders, mahogany, and teak trees. Elsewhere, I grow cashew, mango, and banana, which give yearly income,” he adds.

Kaspar grows lemon, coconut, and jackfruit, besides rice and vegetables. Sampath, who grows coconut, neem, and jackfruit in four acres, says that jackfruit never fails to give good returns. “I have 200 jackfruit trees. Even if I lease it out for the minimum of ₹1,000 per tree, I get ₹2 lakh,” he adds. In addition to the trees, he grows sugarcane in three acres, and maize and paddy in two acres each.

Chinnappa grows black gram, chilly, groundnut, and vegetables, not only as inter-crops but also as stand-alone crops. “Practising multi-crop system means we harvest a different crop at a different time. So, we get a steady income throughout the year. Also, even if one crop fails, the next one will help us,” says Kannan, son of Maram Thangasamy.

Trees in time of need

In times of necessity, the farmers fell a tree and sell the timber, or use it for themselves. “When I built a house, I found out that a single door frame cost ₹50,000. I cut one jackfruit tree and made all the doors and windows with the wood,” says Sampath.

Though the farmers feel concerned about the depleting ground water, they remain hopeful that the monsoons will improve the situation, as has happened in the past. They practice crop rotation, choosing crops to ensure optimal use of water and also to ensure the reclamation of soil fertility. “Maize will suck all the nutrients. So we grow black gram and groundnut after we harvest maize. When we harvest the pulses, we leave the roots behind, as they help in nitrogen fixation,” Sampath explained to VillageSquare.in.

Food and financial security

Some farmers like Kannan grow rice and vegetables for their consumption alone. Either way, the farmers are assured of food security. The farmers are unable to quantify the difference agroforestry has made in monetary terms. But they show their new houses, personal and farm vehicles, and their ability to send their wards to professional courses as proof of their prosperity.

“Trees are not only farmers’ assets, but the country’s too,” declares Ramanathan, reciting a poem he has written about the benefits of growing trees. Concurring this, Rajesh, a farmer in his 20s, says that this multi-crop agroforestry system has helped the farmers of this region move from subsistence farming to food security, and to financial security now.
