Abstract
Grain yield and harvest index also influenced significantly with the application of zinc and silicon and maximum grain yield was recorded with the application of 150:80:40 NPK + two Zn spray 0.5% (65.88 q ha-1) followed by treatment 150:80:40 NPK + Two Si spray @ 0.3% (63.46 q ha-1) and lowest in T1 control (30.12 q ha-1). Harvest index was recorded non-significant.
Highlights
As a semi-perennial, semi-aquatic grass, when grown in flooded-soil conditions, rice (Oryza sativa L.) is able to act as a conduit for gases from the soil to the atmosphere through aerenchyma tissue [1]
Initial soil-test P and K were above optimum ( > 50 mg kg-1) and optimum (131 to 175 mg kg-1), respectively, while soil Ca, Mg, S, and Mn were all above the low soil-test levels, the only category given for soil Ca, Mg, S, and Mn concentrations for fertilizer recommendations for rice grown in Arkansas [24]
A comprehensive and mechanistic understanding of how environmental parameters interact with greenhouse gas (GHG) production and release can lead to the evaluation and design of new management practices, especially in rice production systems, where, to date, numerous studies are focusing on mitigation and abatement techniques
Summary
As a semi-perennial, semi-aquatic grass, when grown in flooded-soil conditions, rice (Oryza sativa L.) is able to act as a conduit for gases from the soil to the atmosphere through aerenchyma tissue [1]. The large amount of water used to flood rice fields and the biochemical reactions that occur in the resulting anoxic environment, which are responsible for the production of methane (CH4), require evaluation across different production techniques in order to determine the best management practices to maintain profitable yields and reduce greenhouse gas (GHG) emissions to the atmosphere [2]. Different water management and field preparation practices greatly affect the production and emissions of GHGs from rice fields [2]. The drying process associated with alternate wet-dry (AWD) and DF water management schemes causes an increase in soil oxidation-reduction (redox) potential and favors oxidation and microbial reactions, such as the Accepted: August 24, 2020.
