Comparative Analysis of Organic Manure Amendments on the Growth and Yield of Wheat

Abstract

Manure is an important agricultural amendment that contains essential nutrients for the soil structure as well as organic matter present in the soil. It contains nutrients such as phosphorous, nitrogen and potassium that provides elevated yield of crop by improving the structure of soil and without deteriorating the ecosystem as compared to the use of inorganic amendments. A field experiment was conducted at Hohai University, Nanjing, China to determine the efficiency of different types of manure on the production and yield of wheat during winter growing season 2023-2024. To evaluate the effects of different treatments like control (T0), sheep manure (T1), cow manure (T2) and poultry manure (T3) randomized complete block design (RCBD) was employed using three replicates. It is concluded that poultry manure was much effective in promoting the wheat growth as compared to the other treatments with sheep manure and cow manure. It has been noted that the incorporation of poultry or farmyard manure significantly improved the grain yield to 6.752 t ha⁻¹, biological yield to 15.674 t ha⁻¹, and grain protein content to 14.7125%. These results showed that poultry manure has tendency to elevate the soil conditions and can increase the wheat growth and yield.
