Abstract
Lysimeter experiments were conducted at Sakha Agric. Res. Station Farm, North Delta, during two successive summer growing seasons (2013 and 2014) to study the effect of algae and compost extracts on some soil proprieties and maize yield (ZEA MAYS L.) under irrigation by low water quality condition in North Delta. The experiments were designed as split- plot with three replicates. The main plots were occupied by sources of irrigation water as: fresh water (F), drainage water (D), well water (W ), blend, F+D (1.15 dS m-1 at ratio of 1:1), F+W (2.01 dS m-1 at ratio of 1:1), D+W (2.65 dS m-1 at ratio of 1:1) and F+D+W (2.0dS m-1 at ratio of 1:1:1). Sub plots were devoted to control, compost extract, algae extract and compost + algae extracts .The main results can be summarized as follows: Different irrigation water sources had a significant effect on increasing salinity of the soil after the harvesting of plants during the two growing seasons, compared to fresh water. Salinity of the soil was slightly increased by application of compost extract and /or algae extract and recorded highest values by compost extract + algae extract during the two growing seasons. Alkalinity of the soil was high significantly increased due to irrigation water sources during the two growing seasons. Salinity and alkalinity of the soil was high significantly increased due to the interaction between irrigation water sources and extracts of compost and algae, during the two growing seasons. Soil bulk density high significantly decreased and porosity high significant increased due to irrigation water sources, extracts of compost, algae and due to the interaction between the treatments, during the two growing seasons. Soil available N, P and K were high significantly increased in the combined treatments of compost and algae extracts than those under their sole application and control, during the two growing seasons. Soil available N, P and K was high significantly decreased with increasing the salinity of the irrigation water sources, during the two growing seasons. Consequently the effect of irrigation water types on N- available can be arranged in the following order D < D+W<F+D< F<F+D+E<F+W, W. Irrigation with fresh water (control) gave the highest yield compared to the other irrigation treatments with different levels of saline water, Grain yield was high significantly decreased due to increasing salinity of irrigation water sources during the two growing seasons. The effect of organic application on grain, straw yield and 100 grain weight can be arranged in the following order compost extract + algae extract <algae extract < compost extract <control. Grain, straw and 100gw of maize were high significantly increased due to the interactions effect between irrigation water types and organic application, during the two growing seasons.
- It can be advised to use well and drainage water in irrigation and mix them with Nile fresh water in safe ratios taking into consideration low quality water characteristics and their impact on soil and plant. The addition of some soil conditioners (60 liters of compost extract Fed.-1 + 2kgm extract of algaeFed.-1), and use a large portion of the drainage water, and agricultural by-products can help as imperative to water deficit and soil improvement consequently, increased food production to face the population growth.
