Wheat production in India faces challenges due to water scarcity and suboptimal nitrogen (N) management practices. To address this problem, a multi-location (9) field experiment comprising of 9 treatments by including nano and prilled urea alone or in combination was conducted under restricted irrigation conditions (only two irrigations i.e., first at crown root initiation stage and 2nd at flag leaf stage) during 2021–2022 and 2022–2023 in randomised block design with three replications in three agro-climatic regions (NWPZ- North Western Plains Zone, NEPZ- North Eastern Plains Zone and CZ- Central Zone) of India. Results indicated that combining recommended nitrogen (RDN) i.e., 90 kg/ha with two sprays of 5% urea increased grain yield by 4.1% and 41.9% in NWPZ and NEPZ, respectively, over RDN alone. Two sprays of nano urea at tillering and jointing stages significantly outperformed the control (Zero N), increasing grain yield by 14.5%, 34.0%, and 19.2% in NWPZ, NEPZ, and CZ, respectively. Moreover, RDN with two sprays of nano urea increased the grain yield and agronomic efficiency by 12.1% and 12.0% in CZ and 25.2% and 24.6% in NEPZ over RDN alone, respectively.

In CZ, applying RDN with two sprays of nano urea provided 15.5% higher net benefit over RDN. The recommendation for wheat cultivation in small-scale farming systems in India under restricted irrigation conditions suggests adopting a nitrogen management approach combining RDN with two sprays of 5% urea in NWPZ and NEPZ or with two sprays of nano urea in NEPZ and CZ improved the productivity, profitability and agronomic efficiency.</p>","PeriodicalId":54947,"journal":{"name":"International Journal of Plant Production","volume":"48 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2024-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141169522","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To combat this menace, a three-year study (2020-21 to 2022-23) was conducted, investigating the effects of rice residue retention (RRR) and rice residue incorporation (RRI) at graded N levels (0, 50, 100, 150, and 200 kg/ha) alongside farmers’ practices. The primary objective was to enhance wheat productivity, profitability, and soil fertility within this system. Pooled analysis revealed that RRR outperformed RRI at lower nitrogen doses, while RRI excelled with 7.5%, 7.4%, and 10.0% higher biological yields at higher nitrogen doses (100, 150, and 200 kg/ha). The success of RRR and RRI was attributed to 10.5% and 5.0% higher effective tiller/m², respectively, compared to farmers’ practices at 150 kg N/ha. Notably, RRR exhibited superior NDVI values at the flag leaf stage (0.76) over farmers’ practices (0.73). At the 150 kg N/ha, RRR displayed a 9.6% lower cost of cultivation compared to farmers’ practices, with 19.6% higher net returns at lower N levels (50 kg/ha), suggesting its greater benefits under low-input conditions. Furthermore, RRR showed the highest benefit-cost ratio (2.75) at 150 kg N/ha, followed by RRI (2.59) and farmers’ practices (2.55). Over the three-year period, RRR significantly increased organic carbon content (0.49–0.54%) compared to the initial value (0.38%), affirming its long-term benefits. Consequently, the adoption of RRR by farmers is a preferable eco-friendly option over RRI and present practices for enhancing wheat productivity within the rice-wheat system. Due to 60–65% saving of fuel with the practice of zero tillage along with rice residue retention, it can reduce CO₂ emission by 120 kg/ha, therefore, its implementation can reduce CO₂ release by 1.62 MT in South Asia per year.

The first year, with lower rainfall, resulted in a 16% decrease in grain yield and dry matter compared to the second year with higher rainfall. The rainfed treatment, supplemented with irrigation at sowing, yielded about 44% of the full irrigation regime in both years.

When accounting for time-lag effects, the correlation between climate change and both phenology and NEE significantly strengthens, with the lagged impact on NEE primarily mediated through changes in phenology. Specifically, climate change accelerates the green-up and heading dates but delays the maturity date, while crop management extends the phenological period. Our findings indicated that during the green-up stage, NEE is mainly influenced by temperature changes resulting from climate change. During the heading stage, it is predominantly affected by crop management, and during the maturity stage, it is impacted by both factors, with crop management having a more significant effect.
