Abstract

An experiment was conducted to study the water requirement of two varieties of SORGHUM i.e. Speedo feed and Nothro feed in split, split-plot design in YAZD-Ardakan area. In this research, EVAPORATIVE PAN INDEXes (EPI) factors (0.4 and 0.6) studied as main factor and IRRIGATION intervals (II) (5, 9 days) and two varieties of SORGHUM considered as subfactors. Water SALINITY in the area was 2358 micro mhos/cm and area was covered with saline soil and considered antisoil in soil classification. Water efficiency in the area was 40% and PLANT INDEX for SORGHUM was calculated 0.3-1.1. Water quantity controlled by Parshal Flume. Parameters like, flowering percentage, number of leaf and tillering, diameter of stem, leaf area and YIELD were recorded in two harvesting times. Results showed that EPI was not significantly effected the YIELD, while IRRIGATION intervals at 9 days reduced the yiels significantly. Total YIELD was 19.2t/h and 14.5t/h and 5 and 9 days IRRIGATION intervals, respectively. Nothro feed variety YIELDs 18.98 t/h and Speedo feed 14.75t/h. While Northro feed variety showed the best result in 5 days IRRIGATION intervals at both 0.4 and 0.6 EVAPORATIVE PAN INDEXes, Speedo feed variety showed at 5 days and at 0.6 EPI. Considering economical use of water in the area and total YIELD (t/h), 5 days IRRIGATION intervals at 0.4 EPI found suitable for the area.
