Abdel-Aal M.H, D. M. khalifa and Abdalla I.M.( 2018). Impacts of Different Rates of Compost,Proline-Spray and Irrigationon Saline Some Soil Properties under Growing of Sudan grass.Menoufia J.Soil Sci.,Vol.3(2018):267-281
Abstract: An experiment was conducted during the season of 2017, at South of Sahl El-Hosainiya Research Station, Agricultural Research Center (ARC) Sharkeia Governorate, Egypt. The experimentaltreatments were:
1) Compost(C)at rates control(C0), 10 ton.(C10)and 20ton./fed (C20) .
2) Irrigation upon 25% available moisture depletion (AMD) (I25%), 50% AMD (I50%)and 75% AMD (I75%).
3) Proline treatments which included spray with 2 mg Proline L-1 (P1) as well as No-Porline spray (P0). Whereas,spraying wasdone at the times 20, 45 and 60 days post-seeding (500L/fed).The crop used was Sudan grass. Two cuts were taken after 60and 120 days from sowing.
Obtained results showed that:
• Soil organic matter increased by 18.4% by (c20). Soil bulk density significantly decreased with the application of compost.Values of total porosity, hydraulic conductivity; field capacity and available water were significantly increased as a result of compost application.
• Available N, P and K in the soil at the end of experiment were greater in treatments receiving compost and irrigated upon depletion of 50% available water (I50%).
• Yield of fresh and dry plant cuts (two cut) were the highest with irrigation upon 50% depletion of water (I50%), compost at 20ton/fed(C 20ton) and Proline-spray (P1).
