Improvement of Egyptian Clover Yield and Quality by Using Bio and Organic Fertilizers in Newly Cultivated Saline Soil

Abstract

This work was performed at Sahl El-Hossinia Agric. Res. Station, El-Sharkia, Governorate, throughout winter seasons of the year 2016/2017 and 2017/2018 to investigate the foliar application of compost tea humic acid, and bio-fertilizer on forage production, seeds, chemical analysis of plant and soil. Using bio-fertilizer; humic and compost tea on plant increases significantly the clover yield. Humic acid recorded that increased of values for yield, yield components and quality as compared by other treatments. Results pointed that forage yield was affected by whole treatments under saline soil conditions. In general, berseem clover treated with humic acid increased the plant height, fresh, dry yield, seeds yield, weight of 1000 seeds, crude protein, fiber fraction, Total carbohydrate, digestible crude protein of forage yield as compared with control. Values of EC and pH of soil were decline due to various traits using foliar application, while the highest rate of EC in soil run to (5.72 dsm-1) at bio-fertilizer. Values of soil properties treated by whole traits were slightly low comparing control (7.72 dsm-1). It is clear that the minimum total costs were those of application of Bio-fertilizer, being 4570 L.E and the maximum total costs were those of the plants received Compost-t rate which was 5180 L.E. Average over all treatments of total costs were 4847.5 L.E for the two season. The highest value of net return per one invested L.E was achieved when using humic acid (5.40 L.E) and Compost-t (4.15 L.E) compared with N fertilization (control 2.63 L.E).
