Synergism of Organic Manure and Mycorrhizae Along with Inorganic Fertilizers on Crop Growth and Yield of Maize

Abstract

Field experiment was conducted during Rabi 2021-22 to evaluate the synergistic effect of organic manure and mycorrhizae on soil health and crop performance in winter maize (Zea mays L.) at Agronomy Research Farm of Acharya Narendra Deva University of Agriculture & Technology, Kumarganj, Ayodhya- 224229. The experiment was laid out in randomized block design and replicated thrice. The experiment consists of 8 treatments i.e. T1 (Control),T2 (100% RDF), T3 (80% RDF + 20% VC+ Mycorrhizae), T4 (80% RDF + 20% PM+ Mycorrhizae), T5 (60% RDF + 40% VC+ Mycorrhizae), T6 (60% RDF+ 40% PM+ Mycorrhizae), T7 (60% RDF+ 20% PM + 20 % VC+ Mycorrhizae), T8 (50% VC+ 50% PM+ Mycorrhizae). Results showed that growth and yields were substantially improved under Treatment T6 (60% RDF+ 40% N- PM+ Mycorrhizae) viz. plant height (cm), leaf area index (LAI), dry matter accumulation (kg ha-1), cob length (cm), number of grain rows cob -1, number of grains cob-1, test weight (g), weight of cob (g), grain yield (q ha-1), stover yield (q ha-1) and biological yield (q ha-1). Conclusively, synergistic incorporation of inorganic fertilizers with organic manure and mycorrhizae can be used with optimum rates to improve crop growth and productivity on sustainable basis.
