Abstract
This work was conducted to study the effect of four sowing dates started on 8'h Nov. with 30 days intervals and three drip irrigation levels i.e. 80, 100 and 120 % Ep' on cv. Paulista of snap bean growth, yield and pod quality. It was carried out al shark el-owlnat region, southern Egypt during two gr~wing seasons at 200012001 and 200112002.
On (he second sowing dale ( a!!! December) where plants were grown under low lunneles. growth parameters, minerals uptake (N,::> and K) and yield components and attributes were significantly increased, but Ihe ,i! harvesl time was Significantly decreased.
Increasing water irrigation quantity from aO% up to 120% Ep gave significant increase in growth characters ( plan I height, number of leaves and branches and dry weight of leaves and branches ) , minerals uptake, yield components ( number of pods I plant , pod weight I plant, early Yield and total yield) and pod quality i.e. pod diameter, length and weight.
Interaction between SOwing date and irrigation lovel had signilicant effect on all characters of this study. High irnqauon level under second sowing date gave signlncant increase in plant growth and minerals uptake as well as yield characters and earlier production
