A survey on rice disease pests and nutritional deficiency classification

Agriculture is critical to our country’s economic success. It yields the most profit in crop production on the farmer’s land. India is a developing country, and agriculture is a major component of the Indian economy, accounting for approximately 17% of GDP. India is also the world’s second largest producer and the largest exporter of rice. Being the chief grain of India, the country has the largest area under rice cultivation, but the optimal yield would only be guaranteed if the field is free from diseases, whether it be fungal or bacteria, pests and nutritional deficiencies. The presented study will be very beneficial for the researchers to recognize any diseases, pests and nutritional deficiencies of the rice plant. As pest attacks also result in damage to the entire field, causing a reduction in the optimal yield production. Plant nutrients are also required for plants’ good overall health. These nutrients are classified into three classes: primary nutrients, micro-nutrients and macronutrients. Each of these nutrients is essential for plant growth and development, but for optimal rice production at least primary nutritional deficiency should be taken care of which includes nitrogen, potassium and phosphorus. Agricultural crop losses directly attributed to fungus are significant, but to increase the productivity to the fullest pest attacks as well as primary nutrition deficiencies must also be detected. In this paper, we have conducted a literature study on various approaches and analysis of rice plant diseases, pests and nutritional deficiencies have been shown in tables which highlight the number of diseases focused, numbers of pests focused and number of nutritional deficiencies focused by different researchers.
