Background: Pulses are wonderful gift of the nature to agriculture. They provide nutrition to human beings and animals as food and feed respectively. Among the pulses, chickpea is an important rabi season crop with high acceptability and wider use in nutritional food basket. A field experiment was carried out on medium black calcareous soil at Junagadh Agricultural University, Junagadh, Gujarat during rabi season 2017-18 under saurastra condition to evaluate agronomic biofortification of zinc in chickpea (Cicer arietinum L.) varieties through seed, soil and foliar application.Methods: The experiment was laid out in factorial randomized block design with three replications. The treatment combinations comprised two varieties viz., GG 1 (V1) and GJG 3 (V2) and six zinc fortification treatments viz., control, seed treatment ZnSO4 @ 3 g kg-1 seed, 0.5% ZnSO4 foliar spray, seed treatment ZnSO4 @ 3g kg-1 seed + 0.5% ZnSO4 foliar spray, soil application ZnSO4 @ 25 kg ha-1 and soil application ZnSO4 @ 25 kg ha-1 + 0.5% ZnSO4 foliar spray. The chickpea was grown with standard package of practices.Result: The results revealed that a significant improvement in 100-seed weight, seed yield, stover yield and biological yield were observed with chickpea variety GJG 3 over GG 1. Significantly higher numbers of pods per plant (45.83) was recorded with variety GG 1. Significantly, chickpea variety GJG 3 was found superior in zinc content and uptake in seed and stover. Under agronomic strategy, zinc fortification through soil application ZnSO4 @ 25 kg ha-1 + 0.5% ZnSO4 foliar spray at flowering and pod filling stages significantly improved yield attribute and yield viz., pods per plant (55.17), seed yield (2288 kg ha-1) and stover yield (3553 kg ha-1) and quality parameters viz., protein content in seed (22.89%) and protein yield (523 kg ha-1), zinc content and uptake in seed and stover (45.98 and 37.51 ppm and 104.87 and 133.35 g ha-1, respectively) over all other zinc biofortification treatments.
