| Abstract | ||||
| Two field experiments were conducted during winter seasons of 2014/2015 and 2015/2016at Sahl El-Hossinia Agric. Res. Station, El-Sharkia – Governorate, Egypt to evaluate the effect of humic acid, compost tea and bio-fertilizer using two methods of application (foliar and soaking) on some chemical and physical soil properties and Egyptian clover (TrifoliumalexandrinumL.) var. Meskawy productivity under saline soil conditions. The soil pH and EC values decreased due to different treatments using soaking or foliar application.The lowest value of EC in soil reached (4.61 dSm-1)by applying humic acid as foliar application.The soil content of O.M increased in caseof bio-fertilizer, humic acid and compost tea compared with control using soaking or foliar application, however, a high increase was attained by humic acid foliar application.The CEC (cmolkg-1) valuewas affected by different fertilizer sources using soaking or foliar application. The high mean value of CEC was 41.42cmolkg-1in case of humic acid foliar application compared with other treatments and control. The highest values of field capacity and available water were found in case of humic acid foliar application compared to other treatments and control using soaking or foliar application. The values of soil bulk density of soil profiles treated by all treatments were relatively low compared to those of control, whereas the maximum decrease exists in soil treated byhumic acid foliar application compared to other treatments and control using soaking or foliar application. Adding humic acid as foliar application increased the soil total porosity values compared to other treatments and control. Data showed that the values of drainable pores (DP) and water holding pores (WHP) were higher than the other pores in different treatments. The highest diameters of dry aggregates were affected by humic acid foliar application compared to other treatments and control. The high values of total stable aggregates were observed incase of humic acid foliar application. Applying bio-fertilizer; humic acid and compost tea on seeds using soaking or foliar application increases significantly the clover yield and yield components except the interaction between treatments and methods of application. Humic acid with foliar application gave the highest values of Egyptian clover yield and yield components as compared by other treatments. The obtained data indicate that the Egyptian clover yield was clearly affected by all treatments under saline soil conditions. The beneficial effects of all treatments compared with control using soaking or foliar application on Egyptian clover yield could be arranged as follows according to the increases in dry yield (ton/fed)of clover: Humic acid > compost tea> Bio-fertilizer > control, for soaked application and humic acid > Bio-fertilizer > compost tea > control, for foliar application. | ||||
