Drought-Resistant Pigeon Pea: A Game-Changer for Farmers in Mbeere, Eastern Kenya

Farmers in Mbeere, Eastern Kenya, have embraced drought-resistant pigeon peas as rains become unreliable, a crop that also assisted them in doubling their incomes and yields due to growing markets.

Maize Disappointments and Rising Costs Drive Farmers towards Pigeon Pea

Traditionally, the farmers heavily relied on maize. However erratic weather patterns coupled with the ever-rising cost of fertilizer have pushed the farmers out of the crop. “The switch to pigeon pea was after years of disappointments in the farms and years of loss-making. It has been the fourth year since we last got sufficient rainfall,” said Jacinta Nyakio one of the farmers who have switched to pigeon pea farming.

According to NyakioNyaga, a mother of four, she had planted 0.8 hectares of maize but was unsure whether she would harvest more than two 90kg bags. “Normally, I get up to 20 bags,” she added. Declining maize yields, due to climate variability and high fertilizer costs, have caused maize prices to soar.

Successful Pilot: Four Drought-Tolerant Pigeon Pea Varieties Shine in Mbeere

Four drought-tolerant pigeon pea varieties have been piloted in Mbeere, and specialists say the crop is hardy and can grow in a range of environments and cropping systems. The International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) is providing farmers with free seeds.

“They select the preferred varieties and sizes,” said Richard Jones, ICRISAT Eastern, and Southern Africa assistant director. The selection is based on maturity times, plant height, stem thickness, amount of leaves, susceptibility to disease, cooking times, and soil types.

“Depending on rainfall availability, one can harvest 750kg per 0.5ha,” said Jones. The new varieties mature in about 120 days while the traditional varieties flower at the end of the long rains, growing to maturity from October to August. “Old varieties will not give you a crop until after the long rains [April-June]. If the long rains fail, then there is no harvest,” he said.

Nyakio said the uptake of the new varieties would be higher if pesticides were provided during the first planting. “The pesticides are very costly for a first-time farmer,” she said.

Pigeon Pea: A Versatile Crop with Multiple Benefits for Farmers and Livestock

Pigeon peas are a high protein dietary staple providing 20 to 22 per cent of the protein where it is grown extensively (India, Myanmar, Nepal, China, and south-eastern Africa).

Besides its de-hulled split peas, its immature green seeds and pods are also used as a vegetable. “We have been experiencing a lot of hunger and the first harvest really helped my family. I did not have to look for beans to mix with the maize to make githeri [a maize and bean stew],” John Ngari, a farmer in the Mbita area said. “I am now trying to move my wife away from growing maize. We can sell some of the pigeon peas and buy maize instead.”

Crushed dry pigeon pea seeds are also fed to animals, while the green leaves are quality fodder. The dry stems are used for fuel. According to Jones of ICRISAT, the pigeon pea is a bonus crop, which can be grown alongside early maturing cereals while acting as a nitrogen fixer.

Pigeon Pea as a Profitable Alternative: A Cost-Effective and Low-Maintenance Crop

“I have not had to add manure or fertilizer as I would have for maize,” said Carol Maringa, a farmer in Gachoka, adding that it was also not labor-intensive. She planned to increase her pigeon pea production.

“Even when I combine the cost of ploughing, seeds, weeding, and spraying, I am still able to make a good profit,” Samuel Mulinge Kyalo, 45, a farmer from Riakanau said.

Urgent Need for Drought-Tolerant Crops to Combat Falling Food Production in Gachoka

According to Fred Njeru, Gachoka Division crops officer, food production in the region has fallen: “Now a big number of people are getting famine relief food and this is not sustainable.”

The hardest-hit localities, he said, are selling their livestock and burning charcoal to meet their food requirements. “We are encouraging farmers to adopt drought-tolerant crops, but this will take time,” he said. “In the long term, farmers should plant drought-tolerant crops to not only meet their food requirements but also to get more income.”

Scaling Up Adoption: Encouraging Farmers to Embrace Drought-Tolerant Crops

According to Jones of ICRISAT, there is a need to scale up the planting of drought-tolerant crops. In Eastern Kenya, about 20 per cent of the farmers have adopted the new pigeon pea varieties, which have been developed using conventional breeding.

Already, there has been about 80 per cent uptake in the eastern Makueni District. “Often, information does not move well,” Jones noted. “It is like lighting a fire, it burns, then it goes out; you have to keep lighting many smaller fires.”
