Title: Sugar Beet (Beta vulgaris) Production by A Package of Some Tillage Systems, Planting Methods and Irrigation Intervals in Guneid Area (Sudan)
Author: Basheeir, Elwaleed Mohammed Hassan
Abstract: The present research study was carried out at Guneid Research Sugar Cane Center during the two seasons of 2014 and 2015.The objective was to investigated the effect of four tillage systems (mouldboard plowing (T1), disc plowing (T2), chisel plowing (T3) and disc harrowing (T4)), three irrigation intervals (7, 10, and 14 days) and two planting methods (manual and mechanical) on sugar beet crop growth and yield. The parameters measured were machinery performance (ground speed, effective field capacity EFC, field efficiency FE and Fuel consumption), some soil parameters (soil moisture content SMC, bulk density BD and infiltration rate), some crop parameters (germination ratio (GR), root thickness (RIMD), root number per feddan (RNPF), leaf weight (LW), root crop yield (RY), polarization or sugar content (Pol%), estimated recovery sugar (ERS%) and sugar beet production (TSB). Production cost and manpower used. A spilt split blot design with four replications was used in this study. The results showed that all machine performance parameters measured were significantly difference. The planter recorded the highest forward speed and EFC (10.6 km/h and 5.1 feddan/h) respectively while mouldboard plow recorded the lowest values as (3.3 km/h and 0.6 feddan/h). The highest FE was recorded by ridger (75.8%). The highest Fuel consumption was recorded by chisel plowing as (7.1 litre/feddan). Tillage treatments significantly (P≤0.05) affected soil moisture and the maximum soil moisture content (22.5%) was recorded at the third depth (30-45cm) by T3 while the minimum soil moisture content (15.5%) was recorded at the first depth (0-15cm) by T4. The irrigation intervals also significantly (P≤0.05) affected soil moisture content at all depths. The maximum soil moisture content (24.8%) was recorded at the third depth (30-45cm) by the 7 days interval while the minimum soil moisture content (10.3%)was recorded at the first depth (0-15cm) by the 14 days interval. In addition tillage treatments significantly (P≤0.05) affected soil bulk density at the second and third depths. The maximum soil bulk density 1.311 g/cm3 was recorded at the third depth (30-45) by T2 while the minimum soil bulk density (1.213g/cm3) was recorded at the second depth (15-30cm) by T2 and T3. Different tillage systems significantly (P ≤0.05) affected RNPF and GR. The maximum value of RNPF 26157 roots/feddan, GR (76.2%) and TSB (4.2 ton/feddan) and were given by T2 treatment, while the maximum RIMD (35.5 cm )were recorded by T3 treatment and the maximum values of Pol% (18.6%) and ERS% (16.9%) were recorded by T4 treatment. While the minimum values of RY, (24.6 ton/feddan) and GR (66.5%) were given by T3 treatment. Irrigation intervals significantly (P≤ 0.05) affected RY, RIMD and TSB. The maximum values of RY (27.6 ton/feddan) and RIMD (35.2cm) were obtained by the10 days interval treatment, while the maximum values of TSB (4.2 ton/feddan) was obtained by the 7 days interval treatment. Methods of planting significantly (P ≤0.05) affected RY, RIMD, RNPF, GR, Pol%, ERS% and TSB. The maximum values of RY (27.4 ton/feddan), RNPF (28309 roots/feddan), GR (79.8%), LW (4.5 ton/feddan) and TSB (4.1 ton/feddan) were recorded by the manual planting method treatment, while the maximum values of RIMD (35.6cm), Pol% (18.4%) and ERS% (15.8%) were obtained by the mechanical planting method treatment. The highest total cost of sugar beet production (4280 SDG) was recorded by T1 with manual planting method and 7 days interval and the lowest total cost of (3290 SDG) was recorded by T4 with mechanical planting and 14 days interval, while the maximum net return of (5624 SDG) was recorded by T2 with manual planting method and 10 days interval and the lowest net return of (2685 SDG) was recorded by T3 with mechanical planting method and 7 days interval. The highest manpower used (219.45 man-h/feddan) for the field operations was recorded for the irrigation every 7days and the lowest manpower used (1.32 man-h/feddan) were recorded by insecticide application operation. It was concluded that using tillage practices with 10 days irrigation interval and appropriate planting method increased sugar production from sugar beet crops at Guneid Research Sugar Cane Center.
