| Abstract | ||||
| A field experiment was carried out at El-Roba village, Baltim, Kafr El- Sheikh Governorate, Egypt during two consecutive growing seasons (Late winter seasons 2003/2004 and 2004/2005) to study the effect of irrigation regimes, organic manure and source and levels of nitrogen fertilizers on tomato yield and water efficiency. The obtained results could be summarized as follows: The highest values of tomato total fruit yields (34.782 and 32.733 ton fed.-1) were obtained from tomato plants irrigated at 1.3 evaporation pan coefficient and fertilized with 10 m3chicken manure fed.-1 and enciabeen (SRF) at 320 kg N fed.-1 in the 1st season and at 240 kg N fed.-1 in the 2nd season. The highest values of N concentration in tomato plants at 70 days from transplanting (4.06 and 4.03 %), P% (0.340 and 0.346 %) and K concentration (3.63 and 3.67 %) were obtained from tomato plants irrigated at 1.3 evaporation pan coefficient with 10 m3 chicken manure and fertilized with enciabeen at 320 kg N fed.-1 in the both seasons. Results indicated that the amounts of seasonal water consumptive use were (84.73, 71.01 and 58.96 cm) in the 1st season and (87.40, 73.09 and 60.54 cm) in the 2nd season from irrigation at 1.3, 1.0 and 0.7 evaporation pan coefficient, respectively. The highest values of water use efficiency (11.816 and 11.947 kg fruits m-3 water consumed by tomato plants) were obtained from tomato plants irrigated at 0.7 evaporation pan coefficient, fertilized with 10 m3chicken manure fed.-1 and fertilized with enciabeen at 320 and 240 kg N fed.-1 in the 1st and 2nd seasons, respectively. | ||||
