Title: Nutrient status of grape orchards in Punjab
Abstract: The nutrient indexing survey of 33 grape orchards in Bhatinda district of Punjab has indicated medium (23%) to high (71%) available P and high (100%) available K in the soils. The petiole analysis also showed high amounts of both P (36%) as wen as K (67%). The concentratioos of Zn, Sand N in the petioles were below their critical limits in 58, 27 and 9% of the samples. The categorisation of the petiole analyses on the basis of yield data confirmed the inadequacy of Zn. Comparison of the data of the present study with those of the 1979 survey in the same area has revealed that the concentrations of P, Zn, Fe and Mn have increased but those of K and eu have decreased over a period of ten years.
