Abstract:
Nitrogen (N) and phosphorus (P) are playing a vital role in several growth attributes of plants, hence they are essentially required in large quantities. However, N and P are present in the soil in limited amounts. Therefore, extraneous application of N and P usually boost potato yield, considering their application dose because higher or lower application rate may exert a negative impact on different growth parameters of potato and hence on overall potato tuber yield. It has been observed that although most of the farmers in the country recognize the application of chemical fertilizers in potato cultivation, they do not use them at their recommended doses due to limited credit supply, high fertilizer cost, lack of knowledge about the use of organic fertilizer etc. Besides, excessive use of fertilizers, mono-cropping, continuous cropping, and abandoning the following system, reduced use of manure and crop rotation may lead to land degradation, poor growth, tuber yield, and quality potato. However, the use of fertilizer is an inevitable concern to meet the present-day food crisis of the ever-increasing population in the world. Therefore fertilizers at their recommended dose areas essential to increase potato yield and ensure long-term food security. In this review an attempt has been made to describe and analyze the trends in current research on nutrient management practices, especially considering N and P, to improve and sustain potato tuber yield.
