Further progress in crop water relations

WebMuch progress has been made in quantifying and understanding crop growth in relation to water in the last 30 years. This led to the development of AquaCrop, the FAO’s crop water productivity simulation model. For this development, FAO organized consultations with recognized authorities and experts from major scientific and academic institutions, WebThe relationship between the stress parameters relative water content (RWC), leaf water potential (LWP) and stomatal diffusion resistance on the one hand and photosynthesis on the other is discussed. Further it is shown how the amount of water needed by the potato crop depends on climate, soil and plant characters.

WebThese water challenges are expected to strongly impact agriculture – a highly water-dependent sector – undermining the productivity of rain-fed and irrigated crops and livestock activities particularly in certain countries and regions. These changes could in turn further impact markets, trade, and broader food security. WebThis review looks at the effect of moisture stress on potato growth, development and production; plant emergence and tuberization were identified as two critical periods when water stress mostly affect final tuber yield and possibilities of conventional and marker assisted breeding to increase drought resistance or tolerance were explored. 14.
