Abstract: The present investigation entitled “Effect of nutrient management on yield and quality of lentil (Lens culinaris Medik.) cultivars” was conducted at Pulse Research Farm, CCS Haryana Agricultural University, Hisar during rabi seasons of 2016-17 and 2017-18 with the objective to find out the impact of nutrient management on growth, yield, seed quality, nutrient uptake and economics of different lentil cultivars. The field experiment was laid out with 30 treatment combinations comprising of three varietal treatments (Sapna, Garima, HM 1) assigned to main plot and ten nutrient management practices allocated to sub-plot of split plot design by replicating thrice. Ten nutrient management practices consisting of combinations of variable rates of vermicompost and chemical fertilizers i.e. N1: control, N2 – RDF (20:40:0), N3: vermicompost (VC) @ 2 t ha-1, N4: 50% RDN+100% RDP+VC @ 1 t ha-1, N5: RDF + 0.5% ZnSO4 foliar application, N6: RDF + 0.5% FeSO4 foliar application, N7: RDF+0.5% ZnSO4+0.5% FeSO4 foliar application, N8: 50% RDN+100% RDP+VC @ 1 t ha-1+0.5% ZnSO4 foliar application, N9: 50% RDN+100% RDP+VC @ 1 t ha-1+0.5% FeSO4 foliar application, N10: 50% RDN+100% RDP+VC @ 1 t ha-1+0.5% ZnSO4+0.5% FeSO4 foliar application. The foliar spray of ZnSO4 and FeSO4 was carried out at pre-flowering and pod formation stage. The cultivar HM 1 produced the best results in terms of primary branches (3.45, 3.61 plant-1), secondary branches (12.22, 12.55 plant-1), total dry matter accumulation (9.75, 9.97 g plant-1), dry matter partitioning (4.84, 4.92 g plant-1) & partitioning coefficient (49.0, 48.8%) in pods, pods plant-1 (106, 108), seed yield (15.86, 16.12 q ha-1), attraction index (0.79, 0.94), harvest index (48.5, 48.2%), total uptake of N (85.7, 86.9 kg ha-1) & P (10.82, 11.39 kg ha-1), net return (16540, 22439 ` ha-1) and BC ratio (1.35, 1.47) over the cultivar Sapna and Garima during 2016-17 and 2017-18, respectively. The extent of increase in seed yield in cultivar HM 1 was 22 & 24 percent over Garima and 23 & 25 percent over Sapna during 2016-17 and 2017-18, respectively. Cultivar HM 1 recorded maximum net return (16540 and 22439 ` ha-1) and BC ratio (1.35 and 1.47) which was 203 & 128 percent and 20 & 21 percent higher than cultivar Garima during 2016-17 and 2017-18, respectively. Although, the cultivar Sapna had higher leaf areas index (LAI), leaves biomass, 1000-seed weight, straw yield etc., which was statistically comparable with Garima in all these aspects. Among nutrient management practices, the application of 50% RDN+100% RDP+VC @ 1 t ha-1+0.5% ZnSO4+0.5% FeSO4 foliar spray (N10) recorded maximum growth and yield attributes, seed yield (16.25, 16.46 q ha-1), straw yield (19.6, 20.2 q ha-1), biological yield (35.8, 36.7 q ha-1), harvest index, content and uptake of N, P, K, Zn & Fe, protein content and economics of lentil during both the years, respectively. Although, this treatment was statistically identical with N9, N8 and N4 in most of these traits i.e. growth, yield attributes, yield, NPK content & uptake in seed and straw etc. This treatment (N10) increased the seed yield of lentil by 53 & 60 percent over control and 23 & 25 percent over RDF during 2016-17 and 2017-18, respectively. The treatment N10 provided the maximum net return (16136 and 22472 ` ha-1) and BC ratio (1.32 and 1.45) during both the years, respectively. The foliar application of 0.5% of each of ZnSO4 and FeSO4 at pre-flowering and pod formation stage improved the Zn and Fe concentration in seed by 7.6 and 10.4% over control, respectively which may help to combat the micro-nutritional deficiency in human beings temporarily.
