Response of Rice Yield and Grain Quality to Combined Nitrogen Application Rate and Planting Density in Saline Area
نویسندگان
چکیده
To determine the combining effects of nitrogen application rate and planting density on rice yield grain quality formation under salinity conditions, a field experiment was conducted in coastal saline area using Oryza sativa L. cv. Nangeng 9108 from 2019 to 2020. The designed with six rates (0, 210, 255, 300, 345, 390 kg ha−1; denoted as N0-N390, respectively) two transplanting densities (334,000 278,000 hills D1 D2, respectively). results indicated that, increase input rate, panicles number spikelets per panicle increased first, subsequently decreased, peaked 300 ha−1 N, whereas filled-kernel weight displayed decreasing trend. were higher treatment compared those D2 treatment, while spikelet an opposite highest N300D1 among all treatments, accompanied by agronomic N use efficiency, actual reached 8060.4 7869.8 2020, respectively. Increased significantly improved processing nutritional quality, reducing appearance cooking/eating quality. Higher transplant conductive but notably reduced Overall, combination 334,000 recommended for relatively better area.
