Abstract
A field experiment was conducted during the winter seasons of 1984-85 and 1985-86 to study the effect of schedules of irrigation, levels of P,O, along with 2 spacings (25 and 50 cm) on physiological characters of pea (Pisum sativum L. sensu lato). The maximum leaf area.plant was noted with 2 irrigations given at 50 and 70 days after sowing and the highest leaf-area ratio with 1 irrigation at 50 days after sowing during both the years.-Application of P,O, improved the leaf area, leaf-area index and leaf- area ratio over the control, but increase in row width reduced these parameters along with relative grow& rate. Significant reduction in relative growth rate of pea was noted with application of irrigation and P,OrReferences

Many physiological characters such as leaf arealplant, leaf-area index and leaf-area ratio might be directly correlated with growth and development of plant and contribute to yield. However, parameters like relative growth rate may have adverse affect on factors increasing yield of pea (Pisum sativum L. sensu lato) crop (Jenson, 1985). Since such information is meagre in pea, an experiment was conducted to assess the effect of irrigation
