Jharkhand farmers’ innovative way to reduce rotting of potatoes


By Deepanwita Gita Niyogi

  • Two- and three-tier bamboo structures are being made by farmers to store potatoes for a longer period of time.
  • Earlier, farmers used to spread harvested potatoes under beds and cots, resulting in blight disease as well as wrinkling and shrivelling of their precious produce.
  • These structures have helped reduce rotting to a great extent. Earlier, if a farmer harvested a quintal of potatoes, 60 kilograms (kg) used to rot. But the bamboo storage facility has brought it down to 10-20 kg.

Anita Devi’s life was different even a year ago. A potato farmer from Jharkhand, her fortunes have taken a turn for the better. Earlier, a distressed farmer dealing with huge post-harvest losses, she has now turned into a confident woman, who can meet unforeseen financial exigencies.

A resident of Chanda village in Ichak block of Hazaribagh district, Jharkhand, Anita earns her livelihood by growing and selling potatoes. However, like most of her fellow farmers, Anita used to suffer heavy losses due to the practice of storing harvested potatoes underneath beds and cots in homes. This not only caused wrinkling and shrivelling of her precious produce, but also resulted in blight disease that made them rot.

Most of these farmers lack proper storage space. As they are smallholders, their production volume is not that high for cold chains. Also, cold chains are expensive and, for many, going long distances to keep produce in cold chains is an issue. Things changed, however, over the last two years.

In 2017, global development organisation Digital Green, along with the Jharkhand State Livelihood Promotion Society, introduced a set of smart practices among Jharkhand’s smallholder farmers, who mainly grow potatoes for subsistence.

One of the innovative interventions introduced was the building of two-tier, three-feet by six-feet bamboo structures where harvested potatoes can be stored. These structures can be dismantled and customised as per needs. “Earlier, if I grew six quintals (600kg) of potatoes, almost three quintals used to rot within three-four months. This structure keeps my potatoes fresh for almost six-seven months,” Anita told Mongabay-India.

The stored potatoes also used to leave ugly marks on the floor, said Reena Devi, a farmer in Ichak’s Shailkala village, who also had a two-tier structure built in her house.

A big advantage is that cleaning of potatoes is not necessary on a regular basis when kept in the bamboo structure. The potatoes get enough light and fresh air and stay firm, she explained. Reena Devi just turns over her potatoes once in 15-20 days.

In Ichak, 312 farmers have had these structures built in their homes. According to Anita’s neighbour, Tanuja Devi, farmers now don’t have to worry about getting rid of their produce at low rates for fear of losing both crop and money. Cultivators can store their produce for months without worrying. The two-tier structure holds six quintals of potatoes, with one stack holding three quintals at a time.

“Apart from being able to store potatoes for our own consumption, we can now wait to sell them when rates are high. I also keep colocasia in my five-month-old bamboo structure after a thorough cleaning,” said Tanuja Devi. Her structure was built over three days by a local carpenter. Tanuja’s income, like most other farmers’, has increased since the bamboo structures came into use. Earlier, 50 kg of potato seeds used to yield 100 kg potatoes (in 2169 square feet) of the land but now 50 kg seeds give 150-200 kg.

Anita Devi has six quintals storage. In October 2019, the rate per kg was Rs 14 but she did not sell at that time. In November, she sold at Rs 25 per kg. When rates are low, farmers don’t sell and keep in these structures. Earlier, the potatoes used to rot a lot and used to become unfit for sale. With these structures, farmers said that the rate of rotting is low which ultimately means an increase in sales and more money for them.

Homegrown innovation

According to the United Nations’ Food and Agriculture Organization, a specialized agency that leads international efforts to defeat hunger, smallholders or family farmers are crucial to the eradication of rural poverty, hunger and malnutrition and in preserving natural resources and biodiversity. About 80 per cent of the world’s farmers are smallholders and supporting them is the need of the hour.

Ritesh Kumar, deputy programme manager at Digital Green, shares how the idea germinated. He said a discussion was held with 150 farmers of the Ichak village who all suffered due to the lack of proper storage facility and that is where this idea first took shape.

As part of Mahila Kisan Sashaktikaran Pariyojana (MKSP), smallholder farmers are covered for improvement of livelihood. Potato bamboo structures and the potato set of practices are also part of the MKSP project. Kumar explained that the talks with farmers gave them an idea about cultivation practices and hurdles. “We came to know, that potato loss was high during storage,” he said.

According to Kumar, the bamboo structures, that promote the idea of household storage, have helped reduce rotting to a great extent. Earlier, if a farmer harvested a quintal of potatoes, 60 kg used to rot. But the bamboo storage facility has brought the loss down to 10-20 kg – a big difference to the farmers.

The two-layered structures cost Rs 1,500 and can come down to around Rs 700 or 800 if the bamboo is provided by the farmers themselves. In Ichak, the cost of some of the structures was borne by the non-profit Srijan Foundation, which is helping Digital Green implement the programme. Dayal Prasad, the block coordinator for Srijan, informed that the non-profit pays for nuts, bolts and carpenters’ fees while most farmers provide the bamboo. In Chanda village, 22 such structures have been built. One needs 4-5 bamboo logs for a two-tier structure.

“The rates of bamboo vary according to quality. Bamboo has been chosen as it is lighter than wood and is not affected by pests,” said Kumari Nikki, a community mobiliser for Srijan Foundation.

As far as the benefits of using bamboo is concerned, it was pointed out that it is definitely cheaper than wood and lighter in weight too but their cost varies according to availability, locality and quality.

Smart practices for greater gains

The bamboo storage structure is part of the potato package of practices, which lays down certain guidelines for increased production. Selection and treatment of seeds is the most important factor according to the package.

Potato package of practices was launched in 2017 by Digital Green to increase potato production in Jharkhand, where its yield has been low compared to other states. Potato was chosen because it is a very basic crop and is cheaper than many other vegetables.

These practices were launched to increase potato production in Jharkhand, which has always been low compared to Bihar where a standard packet of seeds yields six packets of potatoes. One packet holds about 50 kg of potatoes. In Jharkhand, the yield stood at three packets. But now, farmers are getting five packets after harvest, thereby increasing their income.

According to Gandori Mahato of Kaladwar village in Ichak, his income from selling three packets used to be Rs 1,500 before he adopted the smart package of practices. But now he is able to make and sell a total of five to six packets.

Potatoes weighing 30-35 grams (they are used as seeds) are considered ideal for sowing, said Prasad. Farmers need to soak the seeds in M-45 solution (a fungicide) for 15 minutes to prevent wrinkling. The sprinkling of Trichoderma (it is used for plant diseases) powder is also important for disease control.

After that, the potatoes are grown on raised beds. Farmers are also advised to dig a set of irrigation furrows for optimum water supply. Mahato has been following these practices for the last two years on his 217 square feet plot. “The distance between the two plants should be six inches. If planted closer, the production goes down,” he said.

Kumar said that in the beginning, 9,000 farmers were targeted by Digital Green for the potato set of practices. Now, the scale has gone up to include 20,000 farmers across 12 districts in 24 blocks of Jharkhand. “Most of these farmers now have more to offer to the markets as production has jumped and post-harvest losses have reduced,” he added.

Uttar Pradesh-based agriculture expert Ravi Bhushan Singh said that potatoes are a perishable item. The harvest period window is usually (low) 15 to 20 days, unlike other crops. This results in a glut and the prices come down. He said storing the harvest for a longer time, therefore, becomes necessary.

“This is where the multi-layered portable structures made of locally available materials was the ideal solution to the problem,” said Singh.
