The purpose of this type is to evaluate the pattern of fertilizer consumption, production trend in India and suggest the sustainable fertilizer based on requirement of various crop, aggro climate zones, soil, and climate. The data for major for fertilizer consuming based on zones and state helps us to understand consumption pattern in our country. During the period of 2007-2011 it was observed the west zone consumption 31,116,73 kiloton’s of fertilizer which was the highest among the four one and was also having highest total annual compound growth rate percentage of 9.68 Among major consuming state of the india Uttar Pradesh was found to be consuming maximum fertilizer, that are 16,621,29 kiloton’s Rice and wheat are the major crops which are consuming 37% and 24% of the fertilizer consumed in india among various crops Climate factor, like rainfall pattern have a very crucial role in this the consumption of fertilizer of as demand increase area of the irrigated.
Agriculture is one of the most important economic activities in almost all the developing countries and also in India. Fertile soil is important for increasing agricultural production. Excess usage of chemical fertilizers is one of the reasons for decline in soil fertility. Public policy plays an important role in influencing the behavior of the farmers. The present chapter reviews the research studies relating to public policy and its impact on agricultural sector. Several researchers have made attempts to evaluate the impact of Agricultural policy on the Soil Fertility Management Practices (SFM). Agricultural policy has been analyzed focusing on its impact on production, prices, exports etc. Similarly, studies on SFM are focused on the documentation of SFM practices under different agronomic conditions and factors influencing SFM.
Empirical literature on impact of agricultural policies has been classified into three sections focusing on the following issues:
1. The studies related to Agriculture, Agricultural policy and Cropping Pattern.
2. The studies on Fertilizer policy and Fertilizer consumption.
3. The studies about Soil fertility management practices.
Various data mining techniques are implemented on the input data to assess the best performance yielding method. The present work used data mining techniques PAM, CLARA and DBSCAN to obtain the optimal climate requirement of wheat like optimal range of best temperature, worst temperature and rain fall to achieve higher production of wheat crop. Clustering methods are compared using quality metrics. According to the analyses of clustering quality metrics, DBSCAN gives the better clustering quality than PAM and CLARA, CLARA gives the better clustering quality than the PAM. The proposed work can also be extended to analyze the soil and other factors for the crop and to increase the crop production under the different climatic conditions.
The paper also aims to recommend that fertilizers should be used in a balanced manner through integrated management of nutrient involving the use of chemical fertilizers, bio fertilizers, compost and vermicompost. Balanced use of fertilizers will reduce harmful effects of chemical fertilizers on the environment and will help in making our agriculture sustainable. It also increases water and nutrients use efficiency, improve grain quality, soil health and give better economic returns to farmers and helps in sustainability. So, for sustainable growth in agriculture sector, it is imperative to reduce demand of chemical fertilizers without hampering food production.
