| Abstract | ||
| Two field experiments were designed in a strip- plot with four replications were conducted in the Farm of Tag El-Ezz Research Station (latitude of 30.560 N and longitude of 31.350 E), Dakahlia Governorate during 2012/2013 and 2013/2014 seasons to study the effect of four plant spatial distributions and irrigation intervals on yield and quality of sugar beet preceded by rice crop. The present work included twelve treatments represent the combinations between four plant distribution patterns (D1: planting on one side of ridges of 50-cm, D2: planting on both sides of ridges of 50-cm width, D3:planting on both sides of beds of 100-cm width and D4: planting three rows on beds of 150-cm width, with hill spacing of 20 cm in case of D1 and D3 and D4 as well as 40 cm in case of D2) and three irrigation intervals [irrigation every 25 days (R1), 35 days (R2) and 45 days (R1)]. The obtained results revealed that plant distribution patterns significantly influenced every studied traits in both seasons, except purity % in the 1st season. The highest values of all studied characters resulted from D3, while the maximum percentages of TSS, sucrose and purity resulted from D1 in both seasons. Applying D3 increased root yield by 21.7, 11.5 and 6.2 % t/fad in the 1st season, corresponding to 18.2, 10.4 and 4.2% t/fad in the 2nd one as compared with D1, D2 and D4, respectively. Irrigation intervals had a significant effect on all studied characters except purity% in both seasons. The highest values of all studied characters produced from R2 treatment, while the highest values of TSS%, sucrose% and purity% were recorded by R1. Applying R2 increased root yield by 3.9 and 8.2% t/fad in the 1st season and 4.9 and 9.3% t/fad in the 2nd one compared with R1 and R3, respectively. Planting on two sides of beds of 100-cm width and 20 cm between hills and irrigation every 35-days recorded the highest productivity and quality of sugar beet under the environmental conditions of North Delta. | ||
