This study was about the water-nitrogen regulation model and its soil nutrient environment effect for increasing yield efficiency of Bromus inermis in Hexi Corridor, Gansu Province, China. used as research object this four irrigation management types nitrogen application levels were set. The (controlled by percentage field capacity (θf) at jointing stage) 75–85% (W0), 65–85% (W1), 55–85% (W2) 45–85% (W3). pure 0 kg·ha−1 (N0), 60 (N1), 120 (N2) 180 (N3). effects on spatial temporal distribution moisture nitrate (NO3−–N), plant height, chlorophyll content, use studied. Results demonstrated that (1) water content (SWC) mainly affected W1 treatment helped maintain shallow (0–40 cm) water’s stability avoided redundancy or deficit 60–80 cm layer. NO3−–N application.

Meanwhile, N2W2 (WUE) (23.12 kg·m−3), N1W1 PFPN (170.87 kg·kg−1). In summary, moderate rate (120 kg·ha−1) combined with mild (65–85% θf not promote high but also avoid deep soil.

To address the problems of extensive field management, low productivity, and inefficient water fertilizer utilization in wolfberry ( Lycium barbarum L.) production, an appropriate nitrogen regulation model was explored to promote healthy sustainable development industry. Based on a experiment conducted from 2021 2022, this study compared analyzed effects four irrigation levels [75%–85% θ f (W0, full irrigation), 65%–75% (W1, slight deficit), 55%–65% (W2, moderate 45%–55% (W3, severe deficit)] application [0 kg·ha −1 (N0, no application), 150 (N1, 300 (N2, medium 450 (N3, high application)] soil distribution, nitrate (NO 3 − –N) migration, yield, water-nitrogen use efficiency wolfberry. The moisture content 40–80 cm layer higher than those 0-40 80-120 layer. average followed order W0 > W1 W2 W3 N3 N2 N1 N0. NO –N 0–80 more sensitive regulation, cumulative amount W1> N0 during vegetative growth period. There evidently change accumulation between different treatments autumn fruit. yield under W1N2 treatment highest (2623.09 ), which 18.04% that W0N3 treatment. consumption each period flowering period, by fruit periods, lowest reached peak value 6.83 ·mm uptake recovery first increased then decreased with increasing application. obtained fruit, were 63.56 8.17%, respectively. Regression analysis showed improved when ranged 315.4 374.3 mm, combined amounts 300.0 308.3 . Additionally, residue reduced, making it optimal management for planting. present findings contribute novel insights into production saving reducing nitrogen, helps improve level productivity Yellow River region Gansu Province other areas similar climate.

The agricultural sector faces the dual challenge of enhancing crop productivity and mitigating environmental impacts. Optimizing nutrient management is vital for sustainable agriculture, particularly in sloping terrains like Himalayan region, where damaged soils require restoration. This study explores synergistic effects urea, poultry manure, zeolite on wheat growth yield degraded mountainous soils. A total twelve treatments were implemented a randomized complete block design, replicated three times. included control (T1); urea nitrogen at 120 kg N ha−1 (UN120) (T2); manure (PM) (T3); zeolite-1 (Z1) 5 t (T4); zeolite-2 (Z2) (T5); UN120 + Z1 (T6); PM (T7); Z2 (T8); (T9); ½ UN (T10); (T11); (T12). treatment demonstrated significant improvements growth, with notable increases shoot length (79.7%), fresh weight (50.8%), root (50.6%), chlorophyll content (53.6%), leaf area (72.5%) compared to control. Wheat its components experienced when treated (UN) zeolites. Among these treatments, exhibited highest efficacy. Nutrient analysis revealed substantial (70.6%), phosphorus (33.3%), potassium (15.6%) concoction zeolites further enhanced levels. Integrating mineral sources organic amendments proved effective Despite positive results, research essential widespread recommendations.

Abstract A deficient supply of both macro- and micro-nutrients (minus one test) will respond negatively to the generative characteristics (cobs seeds) maize plant. The aims this study were (1) determine impact nutrient omission techniques fertilization on cob seed developments plants, (2) investigate relationship between seed. This was conducted in a farmers’ field, Medan Selayang, North Sumatra, Indonesia from May September 2023. single-factor Randomized Block Design selected with three replications, namely elimination macro (N, P, K, Ca, Mg, S) micro (Mn, Zn, Fe, Cu) nutrients. Data analyzed by ANOVA followed DMRT at P <0.05 as well Pearson correlation. results indicated that among fertilization, absence nitrogen significantly inhibited highest development 12.61 30.48% not fertilizing manganese ranging 8.45 28.72%. Cob woody ring diameters positively correlated increased embryo length, crown width, length maize.
