Productivity and Water Use Efficiency of Two Canola Genotypes Under Different Irrigation Systems, Fertigation Levels and Sowing Space in New Vally.

In order to increase productivity in Egypt, we must be cultivate oil crops outside the Nile Valley to conduct the strategic goal to minimizing the gab be-tween oil production and its consumption. The field experiments were conducted in a sandy loam soil at Experimental Farm of the Agricultural Research Station, New valley Governorate during the winter seasons of 2011/2012 and 2012/2013. The objective of this investigates was aimed to study the productivity of two ca-nola genotypes under modern irrigation and fertigation systems which preferable as a new techniques in the newly reclaimed soils. The relationship among plant, soil and water are presented in the form of consumptive water (CU) and the wa-ter use efficiency (WUE) of two canola genotypes, fertigation levels and plant spacing under sprinkler and drip compared with surface irrigation systems. Re-sults revealed that tallest plants, No of primary racemes/plant, No of sili-quas/plant, seed index and consequently seed yield/plant (gm) were obtained un-der drip irrigation system compared with the other irrigation systems. Planting Serw 6 genotype under fertigation rate of 60, 30 and 36 kg/fed of N, P2O5 and K2O, respectively with 10 cm sowing space and one plant in hill must be recom-mended. The results indicated that highest water use efficiency (WUE) was ob-tained from sown Serow 6 genotype compared with the other genotypes. Drip irrigation system proved to be the best in decreasing consumptive use (CU) and consequently increased water use efficiency (WUE) compared to either sprinkler or surface irrigation systems. It could be recommended that soun of Canola Serow 6 genotype in hills 10 cm between in rows 20 cm abart one fertigation using 60, 30 and 36 g N,P2O5 and K2O, respectively during drip irrigation to maximize Canola productivity and increase water use efficiency under of soil condition of New Vally governorate.
