Zinc (Zn) deficiency prevails in different soils and crops of the world. Soil Zn deficiency adversely affects growth, yield and micronutrients (Zn, copper (Cu), iron (Fe) and manganese (Mn)) concentration in different crops including pigeonpea (Cajanus cajan L. Millsp.), a protein rich legume crop grown consumed in different parts of the world. Therefore, we carried out a 2-years field experiment on a Zn-deficient Vertisol with 20 different pigeonpea genotypes and 3 levels of Zn treatments in a split-plot design with 3 replications, to study the effect of Zn application on yield, micronutrients concentration and uptake by pigeonpea genotypes. The 3 levels of Zn treatments were no Zn (no Zn fertilizer was applied), soil Zn (20 kg Zn ha⁻¹) and soil + foliar Zn. Compared to no Zn application, soil and soil + foliar application of Zn enhanced mean grain yield by 15 and 24%, stover yield by 13 and 29% and total biomass yield of pigeonpea genotypes by 13 and 29%, respectively. Soil + foliar application of Zn significantly increased mean grain Zn concentration by 33% compared to no Zn application. Soil and soil + foliar Zn application led to reduction in mean grain Cu concentration by 9 and 10%, respectively, and did not significantly increase or decrease grain Fe and Mn concentration. Soil and soil + foliar application of Zn significantly increased mean grain Zn, Fe and Mn uptake by pigeonpea genotypes compared to no Zn application. Soil + foliar application of Zn had significantly higher mean grain Zn, Fe and Mn uptake compared to soil Zn application. The grain, stover and total biomass yield, micronutrients concentration in grain and stover and micronutrients uptake by the genotypes were different under various treatments. The genotypes ICPL 87119, BDN 2, JKM 7, Virsa Arhar 1, DT 23 and AAUT 2007–10 under soil application of Zn and ICPL 87119, BDN 2, JKM 7 and Virsa Arhar 1 under soil + foliar application of Zn were found promising for cultivation to obtain higher grain yield and micronutrients uptake.

锌（Zn）缺乏症在世界各地的土壤和农作物中普遍存在。土壤缺锌对包括木豆（Cajanus cajan L. Millsp。）在内的不同农作物的生长，产量和微量元素（锌，铜（Cu），铁（Fe）和锰（Mn））的浓度产生不利影响，这是一种食用富含蛋白质的豆类作物在世界的不同地方。因此，我们在具有20个不同木豆基因型和3种水平的Zn处理水平的锌缺乏型Vertisol上进行了为期2年的田间试验，并进行了3次重复的分块设计，以研究Zn施用对产量，微量元素浓度的影响。和木豆基因型的吸收。锌处理的3种水平分别为：无锌（不施用锌肥），土壤锌（20千克锌ha ^-1）和土壤+叶面锌。与不施用锌相比，土壤和土壤+叶面施用Zn分别使基因型木豆的平均谷物产量提高了15％和24％，秸秆产量提高了13％和29％，总生物量提高了13％和29％。与不施用锌相比，土壤+叶面施用Zn可使平均籽粒Zn浓度显着增加33％。土壤和土壤+叶面锌的施用分别使平均晶粒铜浓度降低了9％和10％，并且没有显着增加或降低晶粒中的Fe和Mn浓度。与不施用锌相比，土壤和土壤+叶面施用Zn显着增加了木豆基因型平均谷物对Zn，Fe和Mn的吸收。与土壤锌施用相比，土壤+叶面施用Zn的平均谷物Zn，Fe和Mn吸收显着更高。谷物 秸秆还田和总生物量产量，谷物和秸秆中微量营养元素的浓度以及基因型在不同处理方式下的吸收差异。锌在土壤中施用的基因型为ICPL 87119，BDN 2，JKM 7，Virsa Arhar 1，DT 23和AAUT 2007-10，在土壤+叶面施用锌的情况下具有ICPL 87119，BDN 2，JKM 7和Virsa Arhar 1种植以获得更高的谷物产量和微量营养素的吸收。
