EFFECT OF IRRIGATION SCHEDULING, SOIL MULCHING AND AMENDMENTS ON SOME SOIL PHYSICAL PROPERTIES, SOYBEAN YIELD AND CROP WATER RELATIONS UNDER CALCAREOUS CLAY SOILS
Calcareous soils generally have some problems; poor soil physical and chemical properties, crusting, salinity and low productivity. Optimizing water application by irrigation scheduling increases water use efficiency, growth and yield of crops in addition to water rationalization. The aim of the present work was to study the effect of irrigation scheduling, soil mulching and soil amendments application rates on some physical properties of a clay calcareous soil and soybean production and crop water relations. A field experiment was conducted at Menshat Rabie Village, Itsa District, Fyoum Governorate, Egypt. Three irrigation treatments were applied i.e., I1 (1.0 of cumulative pan evaporation, C.P.E.), I2 (0.8 of C.P.E.) and I3 (0.6 of C.P.E.). Two soil mulching treatments were applied, i.e., without soil mulching and black plastic mulching. The effects of two soil amendments namely poultry manure and agriculture sulfur were also tested. Three levels of each soil amendment were applied: (17.86, 35.71, and 53.57 m3 ha-1 of poultry manure) and (178.57, 357.14 and 535.71 kg ha-1 of agricultural sulfur). The experiment included 36 treatments distributed in a split split design with three replicates. Soybean (Glycine max. Giza 111 variety) was grown along two successive seasons (2014 and 2015). Obtained results showed that the applied treatments resulted in significant and considerable effects on the studied soil properties such as, decreases of soil bulk density and increases each of total porosity, available water content, soil hydraulic conductivity values and soybean plant growth and productivity. Applied treatments improved water consumptive use and increased the water use efficiency values of soybean crop. It was concluded the application of irrigation treatment 0.8 of cumulative pan evaporation with the use of poultry manure at the rate 53.57 m3 ha-1 under mulching with black plastic were superior than all other studied treatments and could save about 20% of water requirements of soybean crop grown on a clay calcareous soil.
