Pesticide residue fears prompt caution on intercropping in apple orchards
Srinagar, Feb 20: As high-density apple plantations expand across Kashmir, horticulture experts are cautioning growers against indiscriminate intercropping, citing rising concerns over pesticide residues, orchard health and long-term sustainability.
High-density orchards, characterised by closely spaced trees, controlled canopies and early bearing, have transformed apple production in the Valley. While the system promises higher yields and quicker returns, specialists say it also requires stricter management practices, especially when selecting crops to be grown between apple rows.
Intercropping has traditionally been a part of Kashmir’s orchard economy, helping farmers supplement incomes and utilise vacant land. However, experts warn that the intensive spray regimes required in apple cultivation—particularly fungicide and insecticide applications that begin early in the season—pose serious risks when edible crops are grown alongside apple trees.
“When food crops share space with apple trees, they are inevitably exposed to spray drift,” said an expert associated with SKUAST-K. “This raises concerns about pesticide residues, especially in vegetables that are consumed fresh.”
Leafy vegetables are considered particularly vulnerable due to their broad surface area and direct exposure to chemical sprays. With spray frequency increasing after March, experts say continuing such crops inside orchards beyond the early season could unintentionally compromise household food safety.
Dr Tariq Rasool, a plant pathologist, said intercrop choices must be guided by agronomic compatibility and health considerations rather than short-term gains. He recommended garlic and legumes as safer alternatives, noting that they compete minimally with apple trees and carry lower risks of residue accumulation. He advised growers to avoid vegetables that are directly consumed and remain highly exposed during routine orchard spray schedules.
Garlic has emerged as one of the most orchard-friendly options due to its underground harvestable part, which limits chemical exposure. It also adapts well to orchard conditions, competes modestly for nutrients and has steady market demand. Legumes such as peas and beans are also encouraged for their ability to fix nitrogen and improve soil health, particularly during the early years of orchard establishment.
Non-food crops are increasingly being promoted as safer diversification options. Lavender, which requires limited water and is suitable for border planting, has drawn attention for eliminating dietary residue concerns while offering returns through essential oil markets and supporting beneficial insects.
In parts of south Kashmir, some growers have already adopted this approach.
Manzoor Ahmad, a progressive farmer from Bijbehara, has integrated lavender into his high-density apple orchard, a move officials say reflects a growing shift towards cautious and science-backed diversification.
Experts caution that tall or aggressive intercrops that compete heavily for water, nutrients or light can disturb the delicate balance required for optimal apple growth. Crops prone to high pesticide retention, they add, may pose risks that outweigh immediate income benefits.
“Any intercrop introduced between apple rows should complement, not compete with the trees,” an expert said. “Scientific crop selection, awareness of spray schedules and attention to residue risks are essential to protect farmer income, fruit quality and consumer health.”
With consumer safety and environmental sustainability gaining prominence, horticulture specialists argue that agricultural success must extend beyond yield alone. In Kashmir’s changing apple economy, they say, informed intercropping decisions will be key to ensuring resilient orchards, safe food and sustainable livelihoods.
