soils. 2 kg silicon/hectare is required for better yield of rice [10, 11].

Silicon is the second most abundant mineral in the earth's crust but is not considered an essential element for many plant species. Silica is considered a beneficial element for rice growth, because it has not been shown that rice fails to complete its life cycle in the absence of Si. Plant species are categorized as either Si-accumulators or non-accumulators. Rice is considered as Si-accumulator specie. Application of Si amendments have been shown to be beneficial to rice growth, yield, and pest reaction in some areas of the United States. Research in Pakistan has demonstrated that Si containing soil amendments have produced significant yield increase on mineral

The change in greenhouse gasses concentration leading to global climate change is evident at present. In this global climate change we can now address plant ability to efficiently use the nutrients available to it whether from chemical fertilizers, manures or what is naturally available in the soil and water by inventing a simple hypothetical

The aim of this contribution is firstly to print out of some if presently available plant nutrition ways to rice crop and secondly to demonstrate the impact of global climate change on the rice crop growth. We should that efficient use of fertilizer material have to potential combat agent the climate change situation. This enables us to construct a new approach of plant nutrition new concept and methods are desperately needed to achieve the goal of sustainable agriculture growth of rice under alarming global climate change situation. Low productivity in rice crop is mainly caused by native low soil fertility and water stress. The low soil fertility is associated with low organic matter and clay content in soil, which also produce low recovery

The field of investigation revealed a linear relationship between paddy yield and fertilizer application rate between N and Zn. Frequent split fertilizer application of slow release fertilizer improved fertilizer recovery efficiency that a key to feature in

The integrated use of natural and chemical fertilizer improved the fertilizer holding capacity that critical factor to enhance rice productivity under all type of rice culture. Application of poultry litter, either fresh or composted, has been shown to be the most effective means of quickly restoring rice productivity to soils that have been altered by precision grading. Graded soils have lower organic matter
