List of top Soil Science Questions on Plant Physiology

Given below are two statements: Assertion (A): Soil water is the most predominant and limiting factor for crop production. The goal of a soil-water-plant continuum is to maintain the soil water between field capacity and wilting point. Reason (R): Most of the plants withdraw water from the soils until soil moisture pressure reaches about 15 bars.

The amount of water including transpiration, plant growth, evaporation from the soil, and drainage loss required to produce a unit of dry weight material is a measure of:
