Abstract
The present study was carried out in Tamil Nadu State of India to quantify and prioritize the constraints causing yield loss in rice. Data were collected from 120 scientists across various disciplines working on rice. Priorities were arrived then by comparing the relative yield losses caused by constraints and ranking them. The total loss in Tamil Nadu was 2.73 million tonnes accounting for about 39 per cent of production. Leaf folder emerged as the major constraint in the study area. The present study attempted to prioritize those constraints by bringing them under the purview of research aimed to eliminate their ill effects on rice yield.
Key words:
Quantification; Prioritization; Rice and Constraints.
