SUMMARY
A field study was conducted during two consecutive years (2018-19 and 2019-2000) at Research Farm, Department of Agronomy, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur to evaluate the infiltration behaviour of soil under eight grass based cropping system combinations. The recommended dose of 150 kg N, 80 kg P2O5 and 40 kg K2O/ha was applied through urea, single super phosphate and muriate of potash. Results revealed that highest (6.1 and 11.6 m/hr) infiltration rate at the initiation (July, 2018) and end (June, 2020) of the study, respectively, was recorded under pearl millet napier hybrid in paired rows + ricebean – egyption clover system, however, sole cropping of guinea grass (GG) system recorded lowest (5.0 and 7.4 mm/hr) infiltration rate at above respective
times which were higher than that recorded before initiation of the study (4.5 mm/hr) during 2016.
