Title: Spatial Variability of Sugar Cane Yield Related To Soil Physiochemical Properties In Gunaid Sugar Scheme
Author: Taha, Huda Hassan
Abstract: This study presents spatial variability of soil physiochemical properties related to sugarcane yield in Guneid Sugar scheme. The study was conducted in Adham and Syeid fields. The parameters measured were soil electrical conductivity (EC), soliable ions (Ca+2+Mg+2), sodium (Na+), pH and sodium adsorption ratio (SAR), in addition yield. In Adham field, the average EC was found to be varied from 0.2693 to 0.2681 dS.m-1, average Ca+2+Mg+2 was varied from 1.1759 to 1.1944m.eq.l-1, average Na+ was varied from 1.2007, to 1.2044 m.eq.l-1, the average pH was just 7.7807, average SAR was varied from 1.5522 to 1.6070 for 0- 15 and 15 - 30 cm, respectively, while average yield was found to be 51.20 Ton.fed-1. In Syied field, average EC was found to varied from 0.2944 to 0.2830 dS.m-1, average Ca+2+Mg+2 was varied from 1.6481 to 1.5648 m.eq.l-1, average Na+ was varied from 1.2689 to 1.2626 m.eq.l-1, average pH was varied from 8.1333 to 8.1993, average SAR was varied from 1.3900 to 1.4374, for depths of 0-15 and 15- 30 cm, respectively, while average yield was found to be 41.0356 Ton.fed-1. Two regression models was formulated and verified to predict soil SAR based EC and pH for Adham field (SAR= 0.727PH+6.419EC-5.835), while based on EC for Syied field (SAR=7.334EC-0.77). Slight to moderate reduction in infiltration rate were evident on both fields based on EC and SAR, except 2.124 Fedan that had severe infiltration rate problem on Adham field based on the relationship between EC and SAR.
