INTRODUCTION:
Agriculture is the most important sector of Indian Economy.Indian agriculture sector accounts for 18 per cent of India's gross domestic product (GDP) and provides employment to 50% of the countries workforce, making it crucial in the overall economy, the survey said. Poor agricultural performance can lead to inflation, farmer distress and unrest, and larger political and social disaffection — all of which can hold back the economy. Recent years have seen the downfall of agricultre. Food and Agriculture Organisation of the United(FAO) states that globally 1.3 billion i.e 33% of food or one-third of all food produced for human consumption is lost every year. These losses are governed by many factors namely lack of land holding,exhaustion of soil due lack of manures,choice of unsuitable crops,climatic changes,pest, weed etc.Among all these factors,about 30-33% of total yeild is lost in India due to pest as stated by P.K. Chakrabarty,asst. director general of plant protection and bio safety. So choosing a suitable crop and prevention of those crops hold an equal priority.It is vital as well as challenging as there are many factor that decides the crop that is suitable for growing and there are many insects which may affect the crops differently.
Many new technologies have been evolved to regain the health of crops. One such technique is precision agriculture.Precision agriculture was born with the introduction of GPS guidance for tractors in the early 1990s, and the adoption of this technology is now so widespread globally.A better name for precision ag might be “site-specific ag”.Indian farmers tend to choose unsuitable crop for their soil and this problem can be solved by precision agriculture where the soil characteristics like soil type,texture,pH value etc are used for detecting that which crop is suitable for cultivation in that soil. This reduces the wrong choice of crop and increases the productivity.Once the seeds are sown it's important for farmers to prevent it from insects and weed.Generally Indian farmers prevent their crops by detecting the pest manually and removing them which requires intense labour. So, using the technology of recommendation system we can recommend the crops suitable for growing and how to remove the pest which often attacks this crops.
