Effect of sulphur and zinc on growth and yield of lentil (Lens culinaris M.)

The experiment was conducted during the period from December to March, 2019-21 at Crop Research Farm, Department of Agronomy, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj to study the effect of sulphur and zinc on yield attributes and yield of lentil. The variety Krish-KLS-09-03 was used as test crop during this experiment. It consists of two factors: Factor A: Sulphur (3 levels); 15, 20 and 25 kg/ha and Factor B: Zinc (3 levels); 4, 5 and 6 kg/ha and one control plot. The experiment was conducted by following a randomized block design with three replications. The results revealed that treatment combination of S at 25 kg/ha + Zn at 6 kg/ha obtained highest in pods/plant (208.53), seeds/pod (1.67), test weight (26.17 g), seed yield (1.84 t/ha), stover yield (3.75 t/ha) and harvest index (32.57%), respectively. On the other hand, control plot showed least values among all of the above parameters. It may be defined that sulphur and zinc had a significant influence on the yield of lentil and 25 kg S and 6 kg Zn per hectare can be the optimum dose for attaining higher yield.
