Background: Cereal based cropping systems are predominantly followed in south Asia because of higher productivity and profitability and ensuring food security. Rice is grown once a year in rotation mainly with wheat. Continuous cultivation of rice results in the formation of a hard pan below the ploughing layer, which may act as a barrier to normal root growth of the subsequent wheat crop. Consequently, soil bulk density is increased and hydraulic conductivity is reduced thus leading to non-conducive soil physical characteristics for the subsequent wheat crop. To reduce these ill effects, FYM is used as organic source. But live stock population is not increasing in the ratio as it is required to meet the FYM demand. Organic source requirement cannot meet through use of FYM in rice-wheat system, which is vital for food security point of view. There is need of alternate cost effective source of FYM which could enhance the soil health as well as productivity of rice-wheat system. The present study aimed to see the efficacy of growing green manure crop (Sesbania aculeata) as an alternative of FYM in the rice-wheat rotation.
Methods: In this experiment conducted during kharif and rabi seasons of 2014-15 and 2015-16 in on-going long term permanent manorial trial since 1984 at research farm (Bihar Agricultural University, Sabour, Bihar, India), twelve treatments were taken under RBD in four replications. Observations and analysis were carried out by following the standard procedures.
Result: The present investigation showed that combination of inorganic fertilizer and Sesbania aculeata helped in increasing yield as well as improving soil health. Sesbania aculeata can be used as a viable and cost effective alternative through partial substitution of inorganic fertilizers to enhance the soil health and productivity of rice-wheat system.
