Feeding Tomorrow: Maize Silage for a Resilient Livestock Farming in India
Livestock is an integral part of Indian agriculture and plays a pivotal role in the national economy. The sector contributes around 4.5% to India’s total GDP and over 25% to agricultural GDP, while providing livelihood support to millions of rural households. Beyond economic value, livestock acts as a reliable buffer against crop failure and of fers a steady income through milk, meat, wool, and manure. With rising demand for animal-based products and a growing focus on sustainable agriculture, the livestock sector holds immense potential to drive rural economic growth, enhance resilience, reduce poverty, and ensure nutritional security across the country. Despite being the world’s largest milk producer, India’s dairy sector faces a major structural challenge: a 32% deficit in green fodder and a 23% shortage of dry fodder. This chronic fodder gap results in inconsistent feed availability, higher input costs, and reduced milk yields—ultimately threatening rural livelihoods as well as national food security. To address this issue, the ICAR–Indian Institute of Maize Research (IIMR), Ludhiana, has launched the project “Upscaling Maize-Based Silage Value Chain in Punjab & Haryana”, supported by the Ministry of Agriculture and Farmers’ Welfare. This initiative promotes maize silage as a sustainable, scientifically proven solution to fodder scarcity, offering farmers a dependable and nutritious feed resource for dairy animals year-round.
Maize is widely regarded as an ideal crop for silage because of its high biomass production, rich starch content, excellent digestibility, short crop duration (80–90 days in spring/rabi and 70–75 days in kharif), round the year availability, and superior storage stability. These traits make maize a reliable and efficient fodder source across diverse production systems. Maize silage is often referred to as the “pickle (achar) of animals” which is high-energy, fermented green fodder preserved under anaerobic conditions. Once ensiled, it becomes ready for feeding within 40–45 days and retains its nutritional quality for several months, providing dairy farmers with a dependable and nutritious year-round feed option. Maize silage is a good source of dry matter (25-35%), energy (Metabolizable Energy), good carbohydrates (14-20% starch), moderate protein (around 8-10% DM), and fiber (NDF ~45-50%, ADF ~25-30%), with fermentation improving nutrient availability, making it a cost-effective roughage rich in minerals like Potassium, Calcium, phosphorus and Magnesium. The whole-plant silage providing balanced nutrition (DM, CP, NDF, ADF, energy), bridging fodder gaps and reducing concentrate costs.
Maize silage promoting in Punjab & Haryana (5 clusters)
IIMR’s interventions span genetic, agronomic, and institutional innovations to strengthen the maize-based silage value chain. High-yielding silage-specific maize hybrids, improved scientific cultivation practices, and mechanized harvesting technologies have been introduced to enhance fodder quality, reduce field losses, and improve overall efficiency. A strategic emphasis on kharif-season silage production was given to promotes crop diversification, reduces groundwater extraction compared to paddy cultivation, and ensures year-round fodder availability, thereby contributing to environmental sustainability in the region. To make silage accessible to farmers of all scales, IIMR has promoted a range of silage preparation models, including pit, drum, bag, and bale silage. These flexible and cost-effective options have catalyzed rural entrepreneurship, enabling the establishment of commercial silage units and strengthening local fodder markets. Through extensive field demonstrations and capacity-building programs, more than 1,000 farmers and dairy stakeholders across five clusters in Punjab and Haryana have been trained in advanced technologies for producing high-quality, nutritious silage.
Impact in action-reducing the fodder shortage: IIMR’s field demonstrations have showcased the transformative potential of maize-based silage in addressing fodder scarcity. The use of whole-plant maize silage, including the cob, has been shown to significantly enhance energy content, leading to improved milk yield (10-20%) in dairy animals. Across nearly 400 acres of demonstrations conducted during both kharif and spring seasons, IIMR’s improved silage cultivation technologies have delivered a 15% increase in fodder yield compared to prevailing farmer practices. IIMR has also highlighted the value of utilizing leftover biomass from baby corn and sweet corn. After cob removal, this biomass often treated as waste can be converted into high-quality silage with supplemental energy sources, effectively turning “waste into feed/wealth” and improving overall crop-use efficiency.
The efforts of IIMR have contributed to the widespread adoption of maize silage, improved fodder availability during lean periods, increased livestock productivity, and the rise of silage-based rural enterprises. To scale out the progress, IIMR is establishing model silage bale-making units in Punjab and Haryana, each costing around Rs. 1.30 crores. These units will function as hubs for demonstration, training, and entrepreneurship development. These units will serve as role models for other silage entrepreneurs and the dairy sector in maintaining high-quality standards. Through these hubs, nearly 3,000 farmer families including maize growers and dairy stakeholders across Punjab and Haryana will be benefited each year.
Driven by scientific rigor and farmer-centric innovation, maize silage is reshaping livestock feeding in North-west India. It is empowering farmers, boosting dairy productivity, and contributing to a resilient, sustainable agricultural future. The IIMR initiative helping in capacity building of silage farmers/entrepreneurs through scientific cultivation and management of maize for silage in 500 acres each in kharif and spring season in both Punjab and Haryana to motivate entrepreneurs and mitigate the fodder shortage in the region.
