Abstract:
Climate change is a natural phenomenon occurring at its own pace since the evolution of earth about 4-5 billion years ago. It gained momentum mainly due to rising greenhouse gases (GHGs) in the atmosphere by burning fossil fuels which affect the Earth’s temperature, precipitation, and hydrological cycles. A field experiment was conducted during Kharif season 2018-2019 at the Forest Nursery and Research Centre, College of Forestry, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj study the “To Study the different date of sowing and Agro meteorological Condition on growth and yield of Maize (Zea maize) crop at Prayagraj condition”. Maize is the third most important cereal crop of world and India after wheat and Rice. Maize has been an important cereal crop sowing to its highest production potential and adaptability to wide range of environment hence called as ‘Queen of Cereals. In horticulture, heat units are regularly communicated as developing degree days (GDD). Now and then developing degree days are called developing degree units (GDU) however the two terms are indistinguishable. Ascertaining GDD for a particular day utilizes a basic equation that includes subtracting a base or limit temperature from the normal temperature through the afternoon. The base temperature is the limit temperature for which plant development starts. The soil of experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH 6.7), low in organic carbon (0.35%), available N (230 kg ha-1), available P (20 kg ha-1) and available K (189 kg ha-1). The result showed that growth attributes viz., highest germination percentage (9.66%), Plant height (170 cm) at 90 DAS, No. of leaves per plant (99) at 90 DAS and Number of cobs/plant (22.82), Test weight (202.18g) and grain yield (30.24q/ha) and Straw yield (41.14 q/ha) was recorded highest under Agro meteorological Condition.
