Influence of Integration of Inorganic Nutrient Sources with Organic Manures on Growth and Yield Attributes of Wheat (Triticum aestivum L.)
Abstract
Afield study was conducted during rabi season 2022-23 and 2023-24 at the Department of Agriculture, Sri Guru Granth Sahib World University, Fatehgarh Sahib on Influence of Integration of inorganic nutrient sources with organic manures on growth and yield of Wheat (Triticum aestivum L.). The experiment was laid out in Randomized Block Design in three replications with 14 treatments. The values for growth attributes such as plant height (81.66 cm), leaf area (6.14 m2), dry matter per meter row length (302.48 g)and no. of tillers per meter row length (124.33) were recorded maximum under T 9 (100 % RDN through chemical fertilizer + 25% RDN through poultry manure) for both years. This was statistically at par with treatment T (100 % RDF (125 kg ha-1)), T (100 % RDN through chemical fertilizer + 25% RDN through FYM) and T (75 % 2 5 7 RDN through chemical fertilizer + 25% RDN through poultry manure). On the contrast, the lowest values were observed under treatment T (control) for growth attributes. Similarly, the yield attributing characters viz., no. of spikes, spike length, total no. 1 of grains and 1000 grain weight were maximum under T and also at par with treatment T and T . The lowest values were 9 2 7 observed under treatment T (no nutrient source) forgiven parameters. This study revealed that integration of organic nutrient 1 sources with inorganic sources showed better results for mentioned growth and yield attributes of wheat crop.

Introduction
Wheat (Triticum aestivum L.) a member of family Poaceae, is chief staple food which supplies approximately 35 percent of total food consumed by the global population (Mohammadi-Joo et al 2015). It is one of the most important cereal crops of the world, which globally stand in second position both in terms of area and production next to rice. In Punjab, it is cultivated over an area of 35.17 lakh hectares with annul production of 165.67 lakh tonnes and average productivity of 47.10 quintals ha-1 (Anonymous, 2022-23). The demand for wheat is expected to increase due to increase in population and affordability due to improved income status of the people (Gangwar et al 2018).
Integrated nutrient management refers to the combination of all possible sources of nutrients like organic, inorganic and biological sources in a judicious way for obtaining an ecologically sound environment and economically optimal farming system (Jat et al 2015). Integrated use of organic and inorganic nutrient sources helps in gaining sustainable yield and improved soil quality for enhanced production (Brar et al 2015). Continuous application of organic manures year after year improves physical and chemical conditions by providing a favourable soil structure, enhanced soil cation exchange capacity, increased quantity and availability of plant nutrients, increase humus content and substrate for microbial activities (Bohme and Bohme, 2006).
Conclusion
Based on present study it was concluded that the combination of RDF and organic amendments helps to improve the growth and yield attributes of wheat which plays important role in the sustainable agriculture. Moreover, the significant improvement ingrowth parameters viz. plant height, leaf area index, dry matter accumulation and number of tillers per meter row length and yield parameters such as number of spikes plant-1, spike length and number of grains spike were also recorded under T (100% 9 RDN through chemical fertilizer + 25% RDN through poultry manure) as compared to other treatments. But, 1000 grain weight show no significant variations among all the treatments. The treatment T Control (no nutrient source) recorded minimum 1 results under all the growth and yield attributes of wheat in both the years.
