“…In these experiments, irrigation increased the number of pods per plant by 13% averaged over both populations. Unlike Stoker (1974) this work showed that severe drought can also reduce the number of seeds per pod and seed weight. While these variates were unaffected in 1983/84.…”

“…The reason why irrigation affects seed yield can be determined by examining the yield components. Stoker (1974) showed that irrigation can have a larger effect on the number of pods per plant and a smaller effect on the number of seeds per pod. In these experiments, irrigation increased the number of pods per plant by 13% averaged over both populations.…”

In two growing seasons, navy beans cv. Sanilac were sown at populations ranging from 44 to 120 plants/m 2 with or without irrigation and shelter in Canterbury. In the two seasons, rainfall was 156% and 66% of the long term mean. Irrigation had the largest effect on seed yield. In 1983/84 irrigated plants yielded 319 g/m2 and unirrigated plants only 278 g/m2. In the drier season, irrigated plants yielded 309 g/m2 while the dryland crop yielded only 131 g/m2. Shelter had only a small effect on seed yield, in only one season, despite reducing wind run by about 40%. Generally, higher plant populations resulted in higher seed yields particularly with irrigation. However in 1984/85, unirrigated crop yield with 30 plants/m 2 was 135 g/m 2 and at 120 plants/m 2 only 125 g/m2. The results indicated that navy beans should be grown with irrigation in Canterbury to be a viable farm option. High plant populations may produce higher yields and ease harvesting problems.

“…When water stress was imposed during the flowering stage, the reduction was greater (Miller and Burke 1983). Stoker (1974) suggested that reduction in yield in dry beans subjected to water stress was caused mainly by abscission of flowers and young pods.…”

Lack of water during vegetative and/or reproductive growth stages is one of the most limiting factors for bean growth. The purpose of this study was to evaluate the effects of water stress applied during two phenological stages (flowering and pod filling) on growth, yield and yield components. Two genotypes of bean (Phaseolus vulgaris L.) were used in this study, cv. Carioca, an indeterminate Brazilian landrace, and cv. Prince, a determinate cultivar grown in Europe. Carioca appears to be generally stress‐tolerant while Prince is intolerant. Plants were grown in large plastic pots covered with a black plastic sheet to protect the soil from rain and evaporation. The water stress treatments were: control (well‐watered plants), WSFS (water stress during flowering stage) and WSPFS (water stress during pod‐filling stage). Water stress reduced yield and yield components at both flowering and pod‐filling stages. The parameters affected were seed weight, number of seeds per plant and number of pods per plant. Number of seeds per pod and seed weight were not affected. No effects of water stress were detected on harvest index. Time to maturity was slightly prolonged, especially for WSFS. Water stress at both stages resulted in lower accumulated water loss compared to the control plants. Water stress during both phenological stages reduced other growth parameters, the number of trifoliate leaves, stem height, number of main branches and number of nodes on the main stem.

“…3, D & E). Stoker (1974) found that even severe water stress to dwarf beans was not able to affect neither seed nor straw yield significantly when introduced after flowering. The influence of higher insolation subsequently turned tess favourable, and likewise the influence of rising temperature when insolation was high.…”

Daily contributions to the final yields were estimated by means of a second order response surface model. The combination of an energy, a temperature and a water state term showed the greatest coefficient of determination. The particular effect on the seed yield of insolation expressed as hours of bright sunshine, was positive from emergence to the ripening period, when no water stress was present. By water stress increasing hours of bright sunshine affected the seed yield negatively. The effect of night temperature was negative though small during the whole life cycle. The haulm yield was negatively affected by increasing insolation during the flowering phase. During the ripening phase a curvilinear effect with an optimum about 8 to 9 hours of bright sunshine was evident. From emergence to first flowering rising night temperature increased yield. During flowering and ripening a curvilinear effect with optimum from 12 to 15°C appeared.
