Abstract:
The paddy crop was harvested at 100% flowering. The initial soils analysis for physico-chemical properties were determined. The concentration and uptake of nutrients (N, P, K, Fe, Mn, Zn and Cu) by upland paddy (Cv. Bhogavati) were determined at 100% flowering. Correlation coefficient between initial soil chemical properties and nutrients uptake without K showed that, the soil potassium was significantly positively correlated with all nutrients uptake without potassium. The soil nitrogen was positively correlated to plant N, P, K, Zn uptake and negatively correlated to plant Fe, Mn, and Cu uptake. The soil phosphorus was significantly positively correlated to plant N, Fe, Zn, Cu uptake and positively correlated to plant P, K, Mn uptake. The soil electrical conductivity, soil calcium carbonate and soil zinc were positively correlated and soil pH, exchangeable calcium were significantly positively correlated to all nutrients uptake by paddy plant. Soil organic carbon significantly positively correlated with plant P, Mn uptake and positively correlated with plant N, K, Fe, Zn,Cu uptake. Soil Fe and Mn were negatively correlated and soil Mg and Cu were significantly negatively correlated with all nutrients uptake by paddy plant.
