Abstract
The Egyptian Government has always been interested in increasing the horticultural “including vegetables” exports in order to increase the national income as well as the foreign exchange currency. Traditionally, growers always relay on their own experience when deciding on the maturity level of the vegetable crops and the optimal harvest time. The main objectives of this research are to determine the optimal harvest time for snap beans (Phaseolus vulgaris L. var Paulista) and Sweet pea’s (Pisum Sativum L. var Sugar Lays) according to physical properties.  The optimal harvest time of snap beans was specified as length ranged from 110 to 140 mm, maximum diameter is ranged from 5.5 to 8.0mm, minimum diameter is ranged from 2.25 to 5 mm, mass is ranged from 2.25 to 5 g, and the moisture content is ranged from 91.17 to 89.8% at about 16 to 22 days from flower appears. The optimal harvest time of sweet peas which has length ranged from 61 to 73 mm, maximum diameter is ranged from 13 to 15mm, minimum diameter is ranged from 9 to 13mm, mass is ranged from 2.5 to 4.5 g, and the moisture content is ranged from 88.5 to 87% at about 12 to18 days from flower appears.
