Abstract

An field experiment was conducted in vertisols during kharif season of 2016 at AICRP on cropping system, college of agriculture, Indore (M.P.) to study the impact of phosphorus levels on growth and productivity of soybean in calcareous vertisols. The area has almost uniform topography with light to medium black vertisols, formed from basaltic parent material. The growth and yield attributes such as seed yield and dry matter yield of soybean was not affected significantly by different levels of applied P in calcareous vertisols. The highest plant height (36.78 cm), no. of branches (6.80), fresh weight/plant (36.59 g), dry weight/plant (8.2), number of pods (8.96), seed yield (2124 kg ha-1) and total dry mater yield (3652 kg ha-1) was obtained under P180 and the lowest (2029 kg ha-1) under P0 soybean in calcareous vertisols.
