Effect of Phosphorous and Boron Levels on Growth and Yield of Lentil (Lens culinaris L.)

Abstract

A field experiment was conducted during Rabi season (2021) at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P.). The soil of experimental plot was sandy loam in texture, nearly natural in soil reaction (pH 7.1), low in organic carbon (0.28%), available Nitrogen (225 kg/ha), available Phosphorous (19.50 kg/ha) and available potassium (213.7 kg/ha). The Treatments consisted of 3 levels of Phosphorous (Phosphorous -30 kg/ha), (Phosphorous -45 kg/ha) (Phosphorous -60 kg/ha) and 3 levels of Boron (Boron -1 kg/ha), (Boron -1.5 kg/ha) and (Boron - 2 kg/ha). The experiment was laid out in Randomized Block Design with 9 treatments and replicated thrice. The results reported that significantly maximum plant height (53.50 cm), dry weight (8.26 g/plant) and a greater number of nodules (7.80) were found higher with application of treatment 60 kg/ha phosphorous + 2 kg/ha Boron. No. pods/plant (103.70), seeds/pod (2.00), test weight (24.38 g), grain yield (1837.72 kg/ha) and Stover yield (2906.16 kg/ha) were recorded in (treatment-9) that is with 60 kg/ha phosphorous + 2 kg/ha Boron.
