Nutritional survey of kinnow orchards soil series at Rawatsar and Fatehgarh of Hanumangarh district of arid Rajasthan

Abstract

The present study was conducted to evaluate the fertility status of kinnow orchards at Rawatsar and Fatehgarh soil series of Hanumangarh district in irrigated area of arid Rajasthan. All kinnow orchards soils were found saline in nature, EC2 of all the orchard soil samples was normal. The calcium carbonate content in soils showed increasing trend with depth, low in organic carbon and available N, low to medium in available P2 O5, medium to high in available K2O content, majority of samples were found high in available Fe, available Mn and low to sufficient in available Cu and low in available Zn content. Leaf N content were found low in kinnow orchards, majority of leaf samples found medium to optimum in leaf P, Fe, and Mn content, whereas leaf K content and Zn content were found low to medium in kinnow orchards. The leaves Cu content were found optimum range in kinnow orchards. Fruit juice N, Fe and Mn content were found low to optimum, whereas fruit juice P, K and Cu content were found optimum and Zn content low at Rawatsar and Fatehgarh soil series of Hanumangarh district.
