Assessment of growth parameters and yield of lentil under different level of phosphorus, sulphur and zinc under Southern Rajasthan

The field experiment was conducted during the winter (rabi) seasons of 2020-21 and 2021-22 at Instructional Farm, Rajasthan College of Agriculture, Udaipur (Rajasthan) to assess the impact of different levels of phosphorus, sulphur and zinc on growth parameters and yield of lentil under Sub-humid Southern Plain and Aravali Hill Zone (IVa) of Rajasthan. Impact of three levels of phosphorus and sulphur and two levels of zinc were evaluated in three replications using factorial randomized block design. The plant growth and yield of lentil were significantly influenced by 40 kg P2O5/ha and 25 kg S/ha along with 0.5% ZnSO4 as foliar spray at 55 days after sowing as compared to other treatment combinations and resulted in to higher dry matter accumulation (9.77, 9.88 and 9.72 g/plant, respectively) and seed yield (1755, 1790 and 1756 kg/ha, respectively). The dry matter accumulation (0.838**) and plant height (0.871**) had a significant and positive correlation with the seed yield in lentil.
