The annual degradation of biological soil health within Northeast China (NC), specifically in the context spring maize (Zea mays L.) cultivation, has been a growing concern. Improving straw management is potential strategy to ameliorate this ongoing deterioration. This study aimed determine responses gaseous nitrogen (N) losses deep-plowed into surface layer. field experiment was conducted from 2019 2021 with six treatments: no (S0N0), half (7.5 t ha–1, S0.5N0), and full return (15 S1N0) without N fertilizer; (S0N200), (S0.5N200), (S1N200) 200 kg ha–1. results indicated that cumulative ammonia (NH3) volatilization increased by 74.6% 120.0% S0.5N200 S1N200 compared S0N200, respectively. nitrous oxide (N2O) emissions were lower S0.5 S1 than S0 48.8% 45.3%, NO3–-N content 0−80 cm layer reduced 48.5% 56.5% S1, respectively, S0. However, agronomic efficiency (AEN) decreased 5.4% 17.6% 2021. Overall, deep incorporation farmland NC primarily NH3 emission short term. it beneficial for reducing N2O avoiding leaching deeper layers. An increase fertilization would better meet demand growth, thus enhancing yield. In future, controlling improve use can further unleash reservoirs, enhance ecological benefits, maintain food security.

Effects of Liquid Urea Rates on Nitrogen Dynamics, Growth, and Yield of Grain Corn (Zea Mays L.)

Research Square (Research Square), Год журнала: 2024, Номер unknown

Опубликована: Май 10, 2024

Arbitrary use of urea fertilizer reduces nitrogen efficiency (NUE) and increases the risk environmental pollution. An experiment was conducted at Universiti Putra Malaysia from November 2019 to March 2020 evaluate application methods rates liquid urea(LU) on yield performance corn. The treatments were, U0 = control, GU100 Granular urea(GU) 100%, LU100 LU LU50 50% LU33 33%, in two equal splits 10th 28th days after sowing (DAS) randomized completely block design, replicates four. Results showed that plant height (206.99cm, 216.92cm, 214.61cm), ear (88.13cm, 88.63cm, 86.00cm), maturity (88.75, 89.00, 86.75), number seeds per kernel row (32.25, 34.50, 33.75), fresh cob weight (10886.60kg/ha, 10946.60kg/ha, 10927.93kg/ha) 100-grain (20.51g, 22.50 g, 21.39 g) corn were not different significantly(p ≤ 0.05) GU100, treatments, respectively. highest found with (6249.03kg/ha) treatment whereas (5666.50kg/ha) (5746.64kg/ha) significantly. Nitrogen(%) plants followed by which significantly higher than treatment. total N content also (102.83kg/ha) though (77.62kg/ha) (83.84kg/ha) treatments. NUE (66.92%) (51.47%) results study suggested best rate while comparable cultivation.
