proved to be the safest and most effective method of increasing and sustaining yield. Various methods fall under organic farming‚ such as composting‚ green manuring‚ legume inoculating‚ and utilizing animal manure as fertilizers. Mulching is a simple process that increases soil fertility and regulating several factors affecting overall plant growth. In this method‚ a layer of material-the mulch-is placed on soil surface around the plant. The mulch is used to retard the growth of weeds‚ protect roots

Theoretical Fluid Mechanics Module#1: 1 1. OBJECTIVE The purpose of this module is to investigate hydrostatic forces on a plane surface under partial and full submersion. 2 2. DESCRIPTION The apparatus shown in Figure 1 will be used. It consists of a quarter circle block attached to a cantilevered arm with a rectangular surface on the other end. The pivot point on the arm corresponds to the center of radius of the block. With no water in the tank‚ and no weights on the

As of 2011‚ 99% of Mercury’s surface has been mapped by NASA. Overall‚ Mercury’s surface has many similarities to the Moon’s surface with many plains and craters. The largest crater on Mercury is the Caloris Basin with a diameter of 1550km. Venus‚ the second planet from the Sun‚ is a solid and rocky terrestrial planet. Named by the

Title______________________________________________________________________ Influence of Rhizobium on the growth and yield of Rice Abstract___________________________________________________________________ Rice (Oryza sativa L.) is one of the world’s most important crops. The present investigation was designed to assess the range of growth-promoting activities of various diazotrophic bacteria on rice seedling vigor‚ its carryover effect on straw and grain yield‚ and the persistence of an inoculant strain on rice roots under greenhouse

Soil is one of the most important natural resources of man. Soils are essential for man for growing crops‚ fodder and limber. Once the fertile portion of the earth’s surface is lost‚ it is very difficult to replace it. In India‚ the destruction of the top-soil has already reached an alarming proportion. Land degradation problems have resulted in increasing depletion of the productivity of the basic land stock through nutrient deficiencies. In addition to the direct loss of crop producing capacity

A shaping process changes the geometry of the work material (machining or forging). A surface processing operation does not alter the geometry‚ but instead alters the properties and/or appearance of the surface of the

The Consequences of Water Pollution Annually‚ 90 million people add to the current population of 6.5 billion. At this rate the global population will reach approximately 8.5 billion by 2025 (http://dieoff.org/page120.htm). As the global population grows exponentially‚ so does the demand for natural resources. Of all these natural resources‚ water‚ is the most vital for survival and expansion. Human’s dependency on water will never go away‚ making it a key part to any civilizations future. It
