Introduction Localized nitrogen (N) supply affects rice N uptake by influencing release, and few studies have examined the effects of root zone distribution growth on yield under localized (LNS). Methods A two-year field experiment was conducted with six treatments: no application, farmers’ fertilizer practice (FFP), four LNS treatments, including two types urea (U) controlled release (CRU) were mechanically side deep fertilized (SDF) or (RZF) at 10 cm soil depth (US, UR, CRUS CRUR respectively). Results Compared FFP, dry matter accumulation, uptake, increased 27%, 21%, 17%, respectively. For type, compared U, NH 4 + -N concentration, total surface area, volume, average diameter, biomass CRU significantly 50%, 43%, 53%, 23%, respectively, which resulted in a significant increase 12%. Regarding application methods, SDF 32%, 24%, 10%, 25% RZF, However, RZF more stable lasted longer, concentration 21% to SDF. Moreover, yield, agronomic use efficiency, gross return 3.15%, 5.62%, 2.81%, CRUS. Conclusion should be selected as recommended types, combination most effective choice for production.

Deep placement of controlled-release urea is an effective fertiliser management strategy for improving the maize productivity, but it not clear whether and how depth affects stem root lodging spring maize. Two consecutive years field experiments were conducted to elucidate properties their relationship between grain yield behaviours under various depths. Results depicted that compared broadcast nitrogen treatment (D0), deep significantly decreased rate by 34.7–80.4%, which contributed mechanical characteristics internode optimising diameter dry matter in third basal as well higher lignin content. In addition, due a greater deeper system (root weight, surface area, length width) larger angle, diameter, tension aerial (37.0–88.4%). Furthermore, increased 100-grain number harvested index constructing system, improved 14.2–38.5%, use efficiency 4.8–10.7%. The highest yield, lowest occurred depths 15 cm. Hence, our study suggests cm efficient improve crop productivity resistance

The optimal combination of the nitrogen fertilizer application and planting density with reference to silage maize yield quality remains unclear. We hypothesized that increasing both would increase yields following law diminishing returns. Yayu26, a cultivar, was used in split-plot experiment investigate effects on growth, nutrient characteristics, chlorophyll fluorescence. main plots were assigned three densities: 60,000 (A1), 75,000 (A2), 90,000 (A3) plants hm−2, subplots four rates: 0 (B1), 120 (B2), 240 (B3), 360 (B4) kg hm−2. results showed rate enhanced yield. Nitrogen accumulation agronomic use efficiency peaked at Structural equation modeling affected properties by influencing fluorescence parameters efficiency, ultimately resulting positive effect A3 × B2 treatments exhibited higher accumulation, potentially compensating for any deficiencies dry-matter Therefore, treatment evaluated as achieve sustainable economically feasible production.
