In a significant stride towards agricultural self-sufficiency, the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) has introduced a groundbreaking variety of pigeon pea, known as ICPV 25444. As farmers grapple with seasonal limitations and climate change, this innovative cultivar promises not only to enhance yields but also to revolutionize the cultivation practices of pulses in India.
The new pigeon pea variety is engineered to mature in just 125 days, making it suitable for cultivation during both the kharif (monsoon) and summer seasons. This is a pivotal breakthrough for Indian farmers, particularly in regions where rice is traditionally followed by fallow periods. With the ability to withstand temperatures soaring up to 45º Celsius, ICPV 25444 provides a viable alternative for farmers often constrained by seasonal crops.
Field trials conducted across Karnataka, Odisha, and Telangana have demonstrated impressive results, revealing yields of up to two tonnes per hectare. This performance surpasses that of traditional pigeon pea varieties, which typically yield between 1 and 1.5 tonnes per hectare. Such advancements are crucial for a country that currently imports a significant portion of its pigeon pea to meet domestic demand.
The development of the speed-bred ICPV 25444 comes at a time when farming communities face increasing environmental challenges, including erratic weather and diminishing water resources. Dr. Himanshu Pathak, the director-general of ICRISAT, remarked on the potential economic impact, stating that farmers cultivating this new variety could enhance their profitability by as much as ₹20,000 per hectare.
Unlike genetically modified organisms (GMOs), ICPV 25444 was developed using speed breeding techniques, allowing researchers to fast-track the growth cycle from 15 years to just five. This method enables the cultivation of multiple generations per year, facilitating rapid crop improvement and timely responses to agricultural needs.
Beyond its remarkable yield potential, the ICPV 25444 pigeon pea offers additional advantages. As a legume, it naturally contributes nitrogen to the soil, enriching the land for future crops. This is particularly beneficial for farmers following rice cultivation, where fields often lie fallow. Furthermore, the cultivar demonstrates strong resistance to prevalent diseases, mitigating the risk of crop loss during the monsoon season.
Water conservation is another significant advantage of this new variety. Traditional rice cultivation in regions like Punjab requires approximately 25 irrigation cycles. In stark contrast, pigeon pea cultivation using ICPV 25444 demands only six to eight irrigations depending on soil conditions, reducing water consumption significantly.
Farmers involved in the trials have expressed enthusiasm about the new variety. “No diseases or pests were observed in our field. We are happy and plan to grow more next summer,” said Gururaj Kulkarni, a farmer who participated in the trials. This positive feedback highlights confidence in the new variety and its potential to enhance agricultural resilience.
The implications of this development are profound, not just for farmers but for India as a whole. Currently, India produces about three million tonnes of pigeon pea annually, with the potential to reach five million tonnes. The introduction of ICPV 25444 could bridge the gap, reducing the reliance on imports and the associated $800 million cost per year.
Looking ahead, ICRISAT aims to expand the cultivation of this variety across other states and engage more farmers in adopting the new methods. Key agricultural regions such as Tandur, Warangal, and Mahbubnagar are being prioritized for future cultivation, which can enhance local economies and improve food security.
