    Abstract : A field study was conducted to evaluate the different forms and levels of potassium on growth and yield of hybrid maize crop in low K soils at farmer's field in Eastern dry zone of Karnataka. The results revealed that among the different sources (forms) of potassium fertilizers, potassium schoenite (S2) increased the growth and yield parameters of maize crop and among the levels of potassium 125 per cent of RDK (L4) has recorded higher growth and yield parameters. Similarly, higher grain yield (77.45 qt ha-1) and stover yield (116.38 qt ha-1) was recorded in treatment (S2L4) which received 125 per cent of RDK through potassium schoenite compared to that of MOP and Bio-K.
