Potassium and magnesium relationship in cowpea ( Vigna unguiculata (L.) Walp.)

摘要: The effects of K and Mg application on dry matter yield uptake K, Ca in cowpea were studied greenhouse at Haryana Agricultural University, Hissar (india). Dry yields leaves, stems roots increased by 17, 30 27 per cent over control due to 150 ppm 16 26 40 respectively. Potassium has antagonistic effect concentration synergistic root concentrations upto 25 K. However, had a 20 all plant parts. Uptake application, but only uptake.
