3. RESULTS AND DISSCUTION
3.1. Meteorological parameters
Daytime average values of meteorological parameters measured by the automatic weather station in experiment period are shown in table 1. Plant in days 41- 44 DAE was in developing stage and in days 59-62 DAE was in mid-season stage. Irrigation has been done on 41, 44, 59 and 63 DAE, which exceptionally because of some problems the last one irrigated with 4 days interval. In the experiment period the 42 and 60 DAE received maximum and minimum solar radiation respectively. Table 1. Daytime average values of meteorological values in experiment period Jour des valeurs moyennes des valeurs météorologiques période dexpérimentation3.2. Energy balance measurements
Daytime average of energy balance measurements in terms of wm2 at soil surface in two irrigation systems are shown in table 2. Net radiation values which was measured in only one irrigation system due to lack of instrument ranged between 304 to 333 wm2. It was considered correctly because all effective parameters on net radiation such as climate and meteorological conditions, soil texture, crop, soil surface color, etc. were the same in two irrigation systems. Then since leaf area index LAI measurement resulted the same values in two irrigation systems, net radiation reaching the soil surface R ns was the same. Since there was short irrigation interval in drip irrigation the crop root zone area and also soil surface was wet. Therefore there were no significant changes in net radiation before and after irrigation. Net radiation measurements also showed R ns values decreased with crop growth and LAI increase as would be expected later in measurement period. Latent heat flux at soil surface accounted for about 32 to 60 wm2 in surface drip irrigation and and 40 to 73 wm2 in subsurface drip irrigation.
