Canola Response to Alternate Furrow and cut-off Irrigation Combined with Bio-Mineral Fertilizer Applications at North Delta Region

Two consecutive winter seasons field experiments were held at Sakha Agricultural Research Station, Kafr El-sheikh Governorate.The productivity of canola, some water relations, and economic returns were the subjects of the study and evaluation of four irrigation regimes: cut-off irrigation at 100% (I1), 90% (I2), and 85% (I3) of furrow length and alternative furrow irrigation (I4); and four fertilization treatments: F1 (recommended dose of NP (100% RNP as control)), F2 (75% RN+100% RP+ rhizobactrien (BioI), F3 (100% RN + 65% RP+ phosphorien (BioII), and F4 (50% RNP+ the mixture of Bio1+ BioII). The findings demonstrated that, in both seasons, the sequence of seasonal water application and water consumptive usage was I1 > I2 > I3 > I4. Comparing the I2, I3, and I4 treatments to the I1 treatment, the water savings were 6.98, 10.47, and 20.11%, respectively. In all seasons, the (I3) and (F3) treatments are superior in raising canola seeds&, oil yield and most of its characteristics. Crop water and irrigation efficiencies as well as groundwater contribution, I4 had the best outcomes over the two seasons. Combining I3 and F3 treatments produced the maximum revenue and profitability of canola seed production; in contrast, I4 and F3 or F4 treatments produced the highest net revenue from the water unit in the two seasons. In conclusion, the most effective treatments for increasing canola production at a lower cost, generating a profit, and conserving water and mineral fertilizers were I3 or I4 treatments in conjunction with F4 treatment.
