Last harvest, many farmers in lower Eastern Kenya were left staring in dismay at their failed maize crops. Once again, droughts had left people in the area desperate; they must purchase maize themselves or rely on famine relief food operations.
However, a few farmers were expecting bumper maize harvestsâ€•neither via miracles nor witchcraftâ€•thanks to a new maize variety which is both drought tolerant and resistant to stalk borers, two of the biggest production constraints in the region.
The variety, referred to as CKIR04003 (CIMMYT/Kenya Insect Resistant), represents joint breeding efforts between the Kenya Agricultural Research Institute (KARI) and CIMMYT, under the Developing Maize Resistant to Stem Borer and Storage Insect Pests for Eastern and Southern Africa – IRMA III Conventional Project (a predecessor to the Insect Resistant Maize for Africa Project). Released in 2006, CKIR04003 has the added advantage of being an open-pollinated, early maturing, and high yielding varietyâ€•31 to 45 bags/ha, according to Stephen Mugo, CIMMYTâ€™s Maize Breeder.
One of the farmers benefiting from the new variety was Paul Ndambuki. He chose CKIR04003 because, as he said, he needed a variety that could withstand droughts as well as being resistant to stem borers. â€œFrom the information provided by KARI, I felt CKIR04003 was the variety I wanted. I did not need any further prodding before trying it out.â€
It was a decision that paid off, despite less than perfect preparation. â€œI got the seeds towards the end of March. Because I was in a rush to plant before the onset of rains, I didnâ€™t plant with fertilizer. I added compound fertilizer only after germination. I had hoped to top-dress with CAN fertilizer. But this did not happen as it rained for only two weeks in the entire growing season. I was a worried man,â€ states Ndambuki. â€œBut my worries gradually turned into amazement. In complete contrast to my neighborsâ€™ farms, under local varieties or other hybrids, my maize was so green and robust. It looked like a crop under irrigation.â€
After six weeks, the maize remained free from stem borers. These borers normally cause huge losses in the region, and also make the attacked maize susceptible to fungal infestation and aflatoxin. Ndambuki got 35 bags of maize from his 0.8 ha of CKIR04003, compared with the 12 bags he had obtained from 1 ha the previous season.
Impressed by Ndambukiâ€™s enthusiasm, KARI has named the variety Pamuka1, in honor of Paul, his wife Jane Mumbua, and the Kamba community.
