Influence of Different Sowing Dates and Nutrient Management on Yield Attributes and Yield of Wheat (Triticum aestivum L.)

Abstract

A field experiment was conducted during Rabi season of 2020-21 and 2021-22 at Livestock farm, Department of Agronomy, College of Agriculture, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur, Madhya Pradesh, India to study the Influence of different sowing dates and nutrient management on yield attributes and yield of wheat (Triticum aestivum L.). The twelve treatments consisting of four sowing dates viz. 25th October, 05th November, 15th November and 25th November as main plot treatments and these were superimposed with three nutrient management i.e. Recommended Dose of Fertilizer, 150% RDF + FYM 15 t ha-1, 150% RDF + FYM 15 t ha-1 + Growth Regulators as sub plots and carried out in split plot design with three replications. On the basis of two year study it is evident that sowing of wheat on 5th November was found to be most suitable than rest of the sowing dates as it recorded significantly higher number of effective tillers (399.91 and 411.94 m-2), length of earhead (10.61 and 11.15 cm), number grains earhead-1 (45.75 and 46.86), grain (5494 and 5497 kg ha-1) and straw yields (7033 and 7128 kg ha-1) compared to rest of the sowing dates except 25th October during both the year. Among the nutrient management, application 150% RDF + FYM 15 t ha-1 + Growth Regulators recorded significantly higher number of effective tillers (405.51 and 416.72 m-2), length of ear head (9.99 and 10.50 cm), grains earhead-1 (45.89 and 46.60), grain (5735 and 5866 kg ha-1) and straw yields (7343 and 7514 kg ha-1) as compared to rest of the nutrient management during both the years.
