“…under the condition of a 20% reduction in water supply, the average yield of grass and tubers increased significantly by 6.31% and 23.13% respectively, compared to the CK treatment ( Figure 4A ). Bhattacharyya et al. (2018) Study on maize in an inceptisol of West Bengal, India found that 50% available soil moisture deficit (CK:75% available soil moisture deficit) significantly increased yield, which is consistent with the results of our study.…”

IntroductionPlastic film mulching (PFM) and deficit irrigation (DI) are vital water-saving approaches in arid agriculture. Cyperus esculentus is a significant crop in dry zones. However, scant data exists on the impacts of these water-saving methods on C. esculentus yield and quality.MethodUsing randomized block experiment design. Three irrigation strategies were tested: CK (standard irrigation), RW20 (20% water reduction), and RW40 (40% water reduction). Mulchin treatments included film mulching (FM) and no film mulching (NFM).ResultsResults revealed substantial effects of film mulching and drip irrigation on soil nutrients and physical properties, with minor influence on grass, root, and tuber stoichiometry. PF treatment, DI treatments, and their interaction significantly affected C. esculentus forage and tuber yields. Initially, grass and tuber yields increased and then decreased with reduced irrigation. The highest yields were under RW20 (3716.31 and 4758.19 kg/ha). FM increased grass and tuber yield by 17.99% and 8.46%, respectively, over NFM. The water reduction augmented the biomass distribuiton of the leaf and root, while reducing the tuber biomass in NFM. FM significantely impacted grass ether extract content, while reduced water influenced grass and tuber crude protein and tuber ether extract content. Mild water stress increased ether extract, crude protein, and soluble matter in grass and tubers, while excessive RW decreased them.ConclusionIntegrating soil traits, nutrients, yield, and quality, findings indicate C. esculentus yield and quality primarily hinge on soil water content, pond hydrogenase, and electrical conductivity. Based on this results, the recommended strategy is to reduce irrigation by 20% for cultivating C. esculentus in this area.

“…Hence, post-silking K accumulation failed to exert significant impact on grain yield. Positive effects of dry matter ( Birch et al, 1999 ; Bodnár et al, 2018 ), N ( Tsai et al, 1992 ; Plénet and Lemaire, 1999 ), P ( Wang and Ning, 2019 ; Ahmed et al, 2020 ), and K ( Bhattacharyya et al, 2018 ; Ul-Allah et al, 2020 ) accumulation on grain yield of maize have been well documented by previous researchers across different geographical locations. Findings of our study agree with those outcomes of the previous research.…”

It is critical to understand nutrient dynamics within different plant parts to correctly fine-tune agronomic advices, and to update breeding programs for increasing nutrient use efficiencies and yields. Farmer’s field-based research was conducted to assess the effects of nitrogen (N), phosphorus (P), and potassium (K) levels on dry matter and nutrient accumulation, partitioning, and remobilization dynamics in three popular maize ( Zea mays L.) hybrids (P3522, P3396, and Rajkumar) over two years in an alluvial soil of West Bengal, India. Experimental results revealed that NPK rates as well as different cultivars significantly ( p ≤ 0.05) influenced the dry matter accumulation (DMA) in different plant parts of maize at both silking and physiological maturity. The post-silking dry matter accumulation (PSDMA) and post-silking N, P, and K accumulations (PSNA, PSPA, PSKA) were highest in cultivar P3396. However, cultivar P3522 recorded the highest nutrient remobilizations and contributions to grain nutrient content. Total P and K accumulation were highest with 125% of the recommended dose of fertilizer (RDF) while total N accumulation increased even after 150% RDF (100% RDF is 200 kg N, 60 kg P 2 O 5 , and 60 kg K 2 O ha –1 for the study region). Application of 125% RDF was optimum for PSDMA. The PSNA continued to increase up to 150% RDF while 125% RDF was optimum for PSPA. Cultivar differences significantly affected both remobilization efficiency (RE) and contribution to grain nutrient content for all tested macronutrients (N, P, and K). In general, RE as well as contribution to grain nutrient content was highest at 125% RDF for N and K, and at 100% RDF for P (either significantly or at par with other rates) for plots receiving nutrients. For all tested cultivars, nutrient remobilization and contribution to grain nutrient content was highest under nutrient-omission plots and absolute control plots. Both year and cultivar effects were non-significant for both grain and stover yields of maize. Application of 75% RDF was sufficient to achieve the attainable yield at the study location. The cultivar P3522 showed higher yield over both P3396 and Rajkumar, irrespective of fertilizer doses, although, the differences were not statistically significant ( p ≥ 0.05). The study underscores the importance of maize adaptive responses in terms of nutrients accumulation and remobilization at different levels of nutrient availability for stabilizing yield.

“…However, inappropriate management of fertilizer N could decrease nitrogen use efficiency (NUE) and result in environmental contamination, 3 particularly in the tropics and subtropics. 4 With limited agricultural land, there is a great need to improve crop yield while minimizing environmental impacts. 5 To achieve yield potentials for direct food and nutritional security in some subtropical regions with high temperature and high humidity conditions (e.g.…”

BACKGROUND: Effective nitrogen (N) management measures are required to control environmental problems caused by N fertilizer use in intensive maize production systems. Soil N losses associated with high precipitation and over-fertilization in maize production can cause substantial environmental problems, whereas there is a lack of quantitative data and effective study countermeasures. A 2-year field study was conducted in the subtropical maize production system in Southwest China to quantify N leaching under varying N application rates of 0, 90, 180, 270 and 360 kg N ha −1 yr −1 . RESULTS: The results indicated that N leaching accounted for 16-38% of N fertilizer input. For farmer practice treatment (360 kg N ha −1 yr −1 ), N leaching loss was high at 110 kg N ha −1 yr −1 and accounted for 31% of the N applied. As an indicator of the ambient water quality pollution, the grey water footprint across all treatments ranged from 376 to 1092 m 3 Mg −1 , with an average of 695 m 3 Mg −1 . Reducing N rate to agronomically optimized treatment (180 kg N ha −1 yr −1 ) significantly decreased N leaching by 77%, and maintained high grain yield of 8.1 Mg ha −1 . The grey water footprint was reduced by 52-63% with N rates from 270 or 360 kg N ha −1 yr −1 to 180 kg N ha −1 yr −1 . CONCLUSION: Nitrogen surplus (applied N rate minus N uptake by maize) resulted in higher soil residual nitrate concentration and consequently high N leaching. High precipitation and low soil pH were the main ecological factors leading to high N leaching.
