Effect of Organic and Inorganic Sources of Nitrogen on Growth, Yield, Quality and Soil Properties of Wheat (Triticum aestivum L.)

The concept of combined use of both organic and inorganic fertilizer should be followed to prevent severe health hazards and to protect the environment. The combined use of organic and inorganic fertilizers is an effective way to maintain nutrient supply, gives organic carbon to soil microbes and mobilizes soil-bound nutrients on decomposition through the release of organic acid. Combined use refers to combining all available nutrient sources, such as organic and inorganic sources with components in a prudent manner to create an environment that is both environmentally sound and economically ideal for farming.

The experiment was conducted at the research farm of the School of Agriculture, Department of Agronomy, Lovely Professional University, Phagwara (Punjab) during rabi season in the year 2021–2022. The objective of the study was to evaluate the “Effect of organic and inorganic source of nitrogen on growth and yield of wheat (Triticum aestivum L.)”. Data recorded on different aspects of crop viz., growth, yield attributes, yield, quality as well as soil chemical properties were recorded and subjected to statistical analysis.

Among various treatments 25% RDN with vermicompost + 75% RDN from inorganic fertilizers showed a significant impact on the growth and yield parameters of wheat crop. Significantly higher growth parameters viz., plant height, number of tillers m^-2, dry matter and relative growth rate were observed in T₁₂ (25% RDN with vermicompost + 75% RDN from inorganic fertilizers) of crop. It was also showed higher significant impact on yield attributes i.e., number of effective tillers^-2, grain yield, straw yield, harvest index, quality parameters as well as soil parameter like available nitrogen, phosphorus and potassium in T₁₂ (25% RDN with vermicompost + 75% RDN from inorganic fertilizers).
