Potential Role of Cropping System and Integrated Nutrient Management on Nutrients Uptake and Utilization by Maize Grown in Calcareous Soil

Abstract

Inroduction Recently, much higher nutrient outflows due to some bad practices followed by farmer's viz., intensive agriculture, neglected cropping sequences and ignored fertilization programs; all these among the factors of soil degradation are the main challenges facing improving agriculture. Thus, low priority is given to increasing the current productivity to meet the present rapid population growth and changing in food preferences, as well as decreasing the gap between total food production and human consumption. Nutrient managements are therefore, a vital component of agriculture strategy plan to 2050. Although, the extension of the cultivated area is an urgent priority for increasing national income, regretfully the most of the allowed lands for reclamation are sandy or sandy calcareous soils contains relatively high

Evaluation of Long Term Different Nutrient Management Practices on Crop Productivity and Soil Quality in Rice (Oryza Sativa)-Potato (Solanum Tuberosum)-Groundnut (Arachis Hypogaea) Cropping System in New Alluvial Soil Zone of West Bengal, India

“…We can also interpret that the integrated application of organic and inorganic nutrient showed highest yield compared to all other inorganic and organic treatments. The result previously supported by many researchers indicated that INM practice can be an effective practice and eco-friendly approach to produce greater yield production and maintain satisfactory stable profitability to farmers (Selim, 2018;Parmar and Sharma, 2002;Cheuk et al, 2003;Sarwar et al, 2007;Sarwar et al, 2008;Abedi et al, 2010;Ghosh et al, 2010;Diacono and Montemurro, 2011). Whereas among all the organic treatment 33% of recommended N each from FYM, vermicompost and Neem cake along with Azospirillum, Azotobacter, Rhizobium and PSB (T5) showed highest yield in all the cropping system.…”

Introduction to the Integrated Nutrient Management Strategies and Their Contribution to Yield and Soil Properties

“…In addition, it can match the crop nutrient requirements and alleviate the constraints of nutrient deficiency without any harmful effects in the environment and products. In contrary, in the case of mismanagement, it always leads to soil degradation, nutrient deficiency, and quick soil runoff [7].…”

“…Since ancient times, farmers have known that soil health can be restored by applying organic manure; accordingly, they used to apply farmyard manure regularly and directly after crop harvest. Consequently, the custom of using organic manures after harvesting has been coupled with restoration of soil health and improvement of physical, chemical, and biological properties of soil, particularly in marginal soils, which are already suffering from low organic matter and low native nutrient content, low productivity, and limitations and unavailability of essential nutrients [3][4][5][6][7].…”

“…Under the heading of INM practices, many subheadings can be introduced, including the use of farmyard manures, natural and mineral fertilizers, soil amendments, crop residues, and farm waste recycling, agroforestry, green manures, and compost [6][7][8][9][10][11].…”

“…In conclusion, integrated nutrient management is a tool which can offer good options and economic choices to supply plants with sufficient amounts of most macro-and micronutrients and also can reduce the dose of chemical fertilizers, create favorable soil physiochemical conditions and healthy environment, eliminate the constraints, safeguard the soil nutrient balance in the long run to an optimum level for sustaining the desired crop productivity, and find safety methods to get rid of agriculture wastes [6,7,[19][20][21][22][23][24][25][26].…”
