Effect of Solid and Liquid Manures on Growth and Yield of Maize (Zea mays L.) in Malwa Region of Punjab, India

A field experiment was conducted entitled “Effect of Solid and Liquid Manures on growth and Yield of Maize” in Agronomy field at Guru Kashi University, Talwandi Sabo. The experiment was conducted in kharif 2023 in Randomized Block Design with three replications, under maize cropping system with eight nutrient management treatments. The data on number of plants revealed no significant difference between all other treatments and plant population observed similar at 30 and 60 DAS and reduced at 90 DAS. Similar to grain yield, the highest stover yield was observed in 75 percent recommended dose of Nitrogen VC Jeevamrit + 25 percent Panchgavya and 100 percent Recommended dose of Nitrogen Panchgavya with the value of 96.4 q/ha and 95.4q/ha, respectively. Solid and liquid manure treatment i.e., 100 percent Recommended dose of Nitrogen Panchgavya resulted in significantly higher dry matter accumulation by maize crop at all the observation stages. The diameter of cob directly affected grain yield and harvest yield. The highest numerical value of 100-grain weight (30.5 g) was recorded with the application of 100 percent Recommended dose of Nitrogen Panchgavya along with 75 percent Recommended dose of Nitrogen VC Jeevamrit + 25 percent Panchgavya. It is dependent mainly on genetic factors and is influenced little by the growing conditions.
