EFFECT OF ORGANIC AND INORGANIC FERTILIZERS ON PHYSICO-CHEMICAL PROPERTIES OF SOIL AND CLUSTER BEANYOGITA SHARMA, AMREEN HASAN, TARENCE THOMAS, ARUN A. DAVID AND TARUN KUMARAbstract An experiment was conducted during Kharif season (July â October) 2021 on crop research farm Department of Soil Science & Agricultural chemistry at SHUATS. The experiment was laid out in Randomized Block Design having three levels of Neem Cake @ 0%, 50%, 100% and three levels of Biofertilizer (Rhizobium) @ 0%, 50% and 100% respectively. The results show that the application of different levels combination of Neem Cake and Biofertilizer increased growth, the yield of cluster bean and improved soil chemical properties. However, some parameters of soilâs physical properties decreased. It was recorded from the application of Neem Cake and Biofertilizer (Rhizobium) treatment T9[ NC @ 100% + R @ 100%] maximum Bulk density 1.177 Mg m-3 at 0-15 cm and 1.382 Mg m-3 at 15-30 cm, Particle density 2.145 Mg m-3 at 0-15 cm and 2.410 Mg m-3 at 15-30 cm, % pore space 45.11% at 0-15 cm and 42.66% at 15-30 cm, Water holding Capacity 59.09 % in 0-15 cm and 48.44 % at 15-30 cm, pH 7.25 at 0-15 cm and 7.46 at 15-30 cm, EC 0.260 dSm-1 at 0-15 cm and 0.230 dSm-1 at 15-30 cm, % Organic Carbon 0.615 % at 0-15 cm and 0.464 % at 15-30 cm, Available Nitrogen 215.12 kg ha-1 at 0-15 cm and 286.90 at 15-30 cm kg ha-1, Available Phosphorus 30.72 kg ha-1 at 0-15 cm and 28.35 kg ha-1 at 15-30 cm, Available Potassium 232.55 kg ha-1 at 0-15 cm and 196.10 kg ha-1 at 15-30 cm. |
