Impact Assessment of Manure and Nitrogen Level on Phenology, Yield Attributes, Yield and Energy Use Efficiency in Pearlmillet

Abstract

A field experiment was conducted at Agronomy Research Area, Chaudhary Charan Singh Haryana Agricultural University, Hisar during Kharif season 2016 to assess the impact of manure and nitrogen on phenology, yield and energy use efficiency of pearl millet hybrid (HHB-223). The treatment consisted of manurial treatment viz. control, biomix, and vermicompost at the rate of 2.5 t ha-1 and vermicompost at the rate of 2.5 t ha-1 + biomix and nitrogen levels viz. 70, 80, 90 and 100 percent recommended dose of nitrogen (RDN). Different nutrient management practices did not differ significantly in respect of various phenological events viz. emergence, five leaf stage and initiation of the milking while boot stage, 50 percent flowering and physiological maturity were affected significantly. Yield attributing characters viz. effective tiller per plant, earhead length, earhead girth, test weight and grain, stover yield affected significantly by the application of manure and nitrogen levels. Among manurial and nitrogen level treatment these character were higher with biomix + vermicompost at the rate of 2.5t ha-1 and 100 percent recommended  dose of nitrogen (RDN). The radiation used efficiency among different treatment there was not  found the significant variation in the incepted photosynthetic radiation use efficiency and lowest radiation use efficiency (RUE) was in grain yield and highest in biological yield of respective treatments.
