Effect of Alternative Irrigation on Tomato (Solanum lycopersicum L.) Growth and Productivity under Clay Soil Conditions

Afield explore was led on tomato plants (Solanum lycopersicum L.) In the mid year times of 2023 and 2024, at Benha College's Staff of Horticulture's Exploratory Homestead in Moshtohor, the location of the experimental site is latitude: 30o36"N, longitude: 31o22"E. The trial was designed as randomized completely block with three replications, where the treatments were I0= traditional irrigation like practice by local farmer within the investigated area I1= alternative irrigation furrow by furrow exchange and I2 = alternative irrigation furrow by furrow fixed through the whole growing season the main findings. The most significant values for all the investigated vegetative parameters were recorded under irrigation treatment I0 on comparison with I1 and I2 . The highest values for early yield, total yield and marketable yield were noticed under I0 in comparison with I1and I2, on the contrary, the unmarketable yield the highest values were record under stress conditions I2. For chemical parameters the highest values of T.S.S% , lycopene and acidity were recorded under irrigation treatment I2 stress conditions, but for V.C were recorded under I0 .The best values for applied water and consumptive use were recorded under irrigation treatment I0 . On the contrary, the highest values for consumptive use efficiency were recorded under irrigation treatment I2. The highest values for Wp and PIW were noted under irrigation treatment I1 comparing with I0 and I2. The values for water saving were observed under using alternative irrigation system.
