SEASONAL VARIATION OF PHYLLOSPHERIC MICROFLORA OF SUGARCANE CROP IN AMBEDKAR NAGAR DISTRICT, U.P.

Abstract

The phyllosphere, representing the aerial surfaces of plants, harbors diverse microbial communities including bacteria, fungi, and yeasts. These microorganisms play a crucial role in plant growth, health, and productivity. The present study investigates the seasonal variation of phyllospheric microflora associated with sugarcane (Saccharum officinarum L.) in Ambedkar Nagar district, Uttar Pradesh. Leaf samples were collected during three major seasons (summer, rainy, and winter) and analyzed using standard microbiological techniques. The results revealed significant variation in microbial population density and diversity across seasons, with maximum microbial load observed during the rainy season and minimum during winter. The study highlights the influence of climatic factors such as temperature, humidity, and rainfall on phyllospheric microbial dynamics.
