A field experiment was conducted during Kharif 2009 under AICRP of MSN at experimental farm of Department of Soil Science and Agricultural Chemistry, Jawaharlal Nehru Krishi Vishwa Vidhyalya, Jabalpur, Madhya Pradesh, India to find out high yielding and zinc efficient genotypes of rice in a Vertisols. The results revealed that the application of zinc @ 20 kg Zn ha-1 as basal +0.5% foliar spray of ZnSO4 was found positive and significant influence on grain yield (4.96 t ha-1) and Zn uptake (384.91 g ha-1) over control (4.04 t ha-1). Among the genotypes, the MTU-1010 was found superior in respect of grain yield (5.44 t ha-1).The highest uptake of Zn recorded by Kranti (350.35 g ha-1) but Swarna recorded the lowest (199.72 g ha-1). However, the cultivar ‘Shyamla’ recorded the highest yield as well as uptake efficiency index and found genetically efficient cultivar, while MTU-1010 was found as genetically inefficient and agronomically highly efficient cultivar.
