A field experiment was conducted during the winter seasons of 2011–12 and 2012–13 at New Delhi, to study the effect of varieties (desi types ‘Pusa 372’ and ‘Pusa 5028’ and Kabuli type ‘Pusa 2024’) and levels of zinc (Zn) (0, 2.5, 5.0 and 7.5 kg/ha) on the yields, protein content, Zn and nitrogen uptake by chickpea (Cicer arietinum L.). ‘Pusa 372’ chickpea recorded the highest grain yield (2.13 tonnes/ha), Zn concentration in grain and straw (42.9 mg/kg grain and 36.8 mg/kg straw respectively), total Zn uptake (229.0 g/ha), protein yield (480.6 kg/ha) and protein content (22.7%) in chickpea grains. Kabuli type ‘Pusa 2024’ chickpea had the lowest protein content (19.9%). Application of Zn significantly increased grain and straw yields, Zn concentration in grain and straw and its total uptake and protein yield, protein content in grain, nitrogen uptake and gross and net returns. It also increased the efficiency of applied fertilizer (NPK), being significantly highest (26.6 kg grain/kg applied NPK) with 7.5 kg Zn/ha and lowest (22.3 kg grain/kg applied NPK) with the control (no Zn).
