Book Description
This study involves the effects of water stress timing and duration on growth, development and yields of dry beans (Phaseolus vulgaris L. variety red Kidney) under field conditions. Emphasis was given to dry matter accumulation and partitioning to different plant parts, development of reproductive organs and yield components.

Book Description
The effects of water stress timing and duration on growth, dry matter accumulation and partitioning, reproductive development and yield components of dry beans (cv. Red Kidney) was studdied in the field at Davis, California. The plants water relations were monitored by measuring leaf water potential and leaf resistance to water vapor diffusion. Soil water content was measured frequently. The following differntail treatment were given in 1976 following uniforms preirrigation, Wet - Irrigation every week to ten days. Symptoms - Irrigation when the plants showed water stress symptoms (dark green foliage). Pod - Irrigation every week to ten days starting in early pod stage. Dry - No irrigation. In 1977, the wet, Pod and Dry treatments were repeated, while the flowering treatment (irrigation every week to ten days starting at blooming) replaced the Symptom treatment. Diurnal variation in leaf water potential followed the usual pattern in the field with -12 to -15 bars minimum in the mid-afternoon. Leaf water potentials in irrigated and unirrigated plants did not differ significantly. Solute potential measurements suggested diurnal osmotic adjustment. Leaf diffusive resistances were not signicicantly different among treatments, Leaf resitance increased with plant age. The average daytime leaf resitance was 4 to 6 sec/cm at day 48 after planting and 6 to 12 sec/cm at day 80. Leaf area index (LAI) was drastically reduced by water stress. In 1977 the Dry treatment reached maximum LAI (1.6) at day 62 after (...).
