ABSTRACT Remote sensing is being increasingly used in agricultural stress management, offering real‐time analysis of crop beyond what can be observed visually alone. Hopper burn, induced by brown planthopper (BPH, Nilaparvata lugens ) a significant challenge to rice production India. This study aims characterize the spectral reflectance plants with different infestation levels 2 nd instar BPH nymphs across three varieties namely Pusa Basamti‐1509, Basmati‐1121, and TN‐1 (susceptible variety BPH). The differential included 0, 5, 10, 20, 40, 80, 100, 200 number nymphs. signatures were collected at 20 40 days after (DAI). results indicated distinct change pattern between healthy infested all green (490–559 nm), yellow (560–584 orange (585–639 red (640–699 nm) region visible portion as affected chlorophyll pigments NIR (700–1800 cell structure water absorption (1915 SWIR portion. specific wavelength band (470, 660,750, 1800, 1915 showing correlation above 0.8 pest severity level, was identified sensitive for assessing damage. Analysis changes wavelengths highlighted that first derivative has strong (500–540 edge position (680–760 nm). amplitude value decreased an increase level insects. identifies sensitivity near‐infrared regions detecting severity.

Rhizosphere Microbiome and Functioning in Alternative Rice Cropping Methods: A Critical Review for Rice Sustainability

Frontiers in Bioscience-Elite, Journal Year: 2025, Volume and Issue: 17(1)

Published: Feb. 14, 2025

Rice is a staple crop worldwide, providing sustenance to over half the global population. The rice microbiome represents complex interaction between plants and their surrounding microbial communities. Plants host various microorganisms in different regions, including rhizosphere, surface tissues, such as rhizoplane phylloplane, inner tissues (endosphere). These engage diverse interactions with plants, ranging from beneficial neutral or harmful. This rhizosphere plays crucial role improving resilience sustainability of cultivation. relationship communities imperative for developing farming practices that maximize yields while minimizing biotic abiotic stresses. Our examination underscores functions microbiota within systems, particularly nutrient uptake, drought resilience, pest disease management, tolerance salinity. review describes types cultivation methods farmers use worldwide improve efficiency production agro–ecological contexts. Moreover, details how alternate cropping influence functioning techniques managing function sustainability.
