Influence of Nitrogen and Boron on Growth and Yield of Lentil (Lens culinaris Medikus.)

Abstract

A field experiment was conducted during Rabi season of 2021-22 at the Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology And Sciences, Prayagraj (U.P.) India. To study the Response of Nitrogen and Boron on growth and yield of Lentil. The treatments consist of nitrogen 10, 20, 30 kg/ha and boron 1.0, 1.5, 2.0 kg/ha. The soil of experimental plot was sandy loamy in texture, nearly neutral in soil reaction (pH 7.8), low in organic carbon (0.35%). Results revealed that the higher plant height (36.40 cm), higher plant dry weight (22.70 g/plant), higher number of pods/plant (174.44), higher number of seeds/pod (1.72), higher seed yield (1.75 t/ha) and higher stover yield (2.67 t/ha) were significantly influenced with application of Nitrogen 30 kg/ha + Boron 2.0 kg/ha. Higher gross returns (INR 89,059/ha), higher net returns (INR 59,652/ha) and higher B:C ratio (2.03) were also recorded in treatment-9 (Nitrogen 30 kg/ha + Boron 2.0 kg/ha).
