Nowadays determining the optimum crop water requirements is considered one of the most important factors affecting plant productions, especially, with scarce water resources. This may be due to the interrelation between the amount of water added and the ability of plant. Two field experiments were carried out during the two growing seasons 2010/2011–2011/2012, at the Research Farm of the National Research Centre in Nubarya region, Egypt, to study the effect of both deficit irrigation and laser land leveling on saving water and increasing yield of wheat crop under Egyptian growing conditions. Studied factors were deficit irrigation (100% Irrigation Requirements "IR", 80%IR, 60%IR and 40%IR) and land leveling techniques (conventional "C" and laser "L"). The following parameters were studied to evaluate the effect of deficit irrigation and laser land leveling; (1) Soil moisture distribution, (2) Growth of wheat plant, (3) Yield of wheat , (4) Irrigation water use efficiency of wheat and (5) Economical parameters of wheat production process. Statistical analysis of the effect of the interaction between land leveling and irrigation on IWUE of wheat indicated that the maximum values were detected at adding 100%IR*L. However, no significant difference was observed between 100%IR*L >80%IR*L >and 60% IR*L, this means that we can save 40% of irrigation water by adding 60% IR with laser land leveling technique to irrigate wheat under sandy soil conditions.
This study contributes in the existing literature to improve water use efficiency of wheat under deficit irrigation conditions and rotational irrigation system by using laser land leveling techniques.

The interaction between tillage tools and soil is of a primary interest to the design and use of these tools for soil manipulation. A new explicit mathematical model to calculate the angle of soil failure plane when soil is cut with narrow tine was developed. Equations of Soil cohesion and soil adhesion cutting factors were partially differentiated with respect to angle of soil external friction, were maximized; Values of angle of soil failure plane were calculated by the model for tine rake angle range from 00 to 900 operated at 0.3 m depth and 0.15 m width in soils with different mechanical properties. It was found that angle of soil failure plane is acute and its values were used for calculating soil frictional cutting factor, soil overburden cutting factor, soil cohesion cutting factor, soil adhesion cutting factor, rupture distance, width of side crescent and soil resistance force. It was found that the force values were realistic. Therefore, the model is valid.

The present study is emphasized on find out the awareness level and perception about e- learning among agricultural research scholars at Banaras Hindu University, Varanasi (Uttar Pradesh) India. This research study is based on the primary source of data which was collected from fifty respondents through structured questionnaire during the year 2013. Statistical tools such as frequency, percentage, and standard deviation were used to analyze the data for making interpretation. In this study, it was found that majority of respondents have a low awareness about e-learning whereby it accounted for 70 per cent of the respondents, 10 have moderate awareness about e-learning and only 20 per cent of the respondents have high awareness about e-learning. Overall awareness of respondents about e-learning tended to be low (M=1.44, SD=0.49, range=9-18). Thus, there is need that government should promote researches on the various aspects of e-learning and maintaining standard of e-learning resources by establishing national level standards of e-resources.
