Popis:	Background: Different levels of nutrient management practice and soil amendments charred rice husk with Arbuscular mycorrhizae during the critical stages of the crop growth enhances the productivity of the groundnut crop. Methods: The field experiments were conducted summer, kharif and rabi seasons of 2016-17 and 2017-2018 at AC and RI, TNAU, Madurai. The main plots consisted of three levels of irrigation scheduling viz., I1- 0.8 IW/CPE, I2- 0.6 IW/CPE and I3- 0.6 IW/CPE ratio and sub plot comprised of four level of nutrient management practices viz., N1-75% of recommended dose of fertilizer with 5t of charred rice husk, N2- 50% of recommended dose of fertilizer with 5t of charred rice husk, N3-75% of recommended dose of fertilizer with 5t of charred rice husk along with seed treatment of Arbuscular mycorrhiza and N4- 50% of recommended dose of fertilizer with 5t of charred rice husk along with seed treatment Arbuscular mycorrhiza. Result: The study revealed that the highest plant height, dry matter production, leaf area index, leaf single photon avalanche diode value, pod yield and haulm yield, nutrient uptake (N,P,K) of groundnut crop and soil enzyme activities in soil was registered with the application of 75% recommended dose of fertilizer and 5t of charred rice husk as basal with seed treatment of Arbuscular mycorrhiza. The highest pod and haulm yield of 1783, 1935 and 1854 kg ha-1 and 4743, 4272 and 4338 kg ha-1 during summer, kharif and rabi’ 2017 seasons respectively of groundnut was registered with 75% of recommended dose of fertilizer and 5t of charred rice husk as basal with seed treatment of Arbuscular mycorrhiza.
