“…Farmers are adopting various practices to enhance the productivity of agronomic and horticultural crops (Khasanah and Rachmawati, 2020 ; Hossain et al, 2021 ; Rehman et al, 2021 ), including intercropping, application of mineral elements, synthetic compounds (Afzal et al, 2020 ; Nurhidayati et al, 2020 ; Abello et al, 2021 ), organic amendments (Iqbal et al, 2020 ; Sarwar et al, 2020 ; Tabaxi et al, 2021 ), plants extracts, and biostimulants (Makawita et al, 2021 ; Khan et al, 2022 ) via soil (Rahim et al, 2020 ), seed coating (Javed et al, 2021 , 2022a ), and seed priming agents and foliar spray (Khan et al, 2017 ; Batool et al, 2019 ; Farooq et al, 2021 ). In a study on rice and its response to urea fertilizer amended with bacteria, Fatma et al ( 2021 ) indicated that amended urea was responsible for the variation in the various biochemical activities. Similarly, several strategies are being utilized to improve the efficiency of slow or controlled-release fertilizers.…”

An ample quantity of water and sufficient nutrients are required for economical rice production to meet the challenges of ever-increasing food demand. Currently, slow-release nitrogenous fertilizers for efficient inputs utilization and maximum economic yield of field crops are in the limelight for researchers and farmers. In this study, we evaluated the comparative efficacy of conventional urea and coated urea (zinc and neem) on rice grown under aerobic and anaerobic regimes in greenhouse conditions. For the aerobic regime, field capacity was maintained at 80–100% to keep the soil aerated. On the other hand, for the anaerobic regime, pots were covered with a polythene sheet throughout the experimentation to create flooded conditions. All forms of urea, conventional and coated (zinc and neem), improved plant growth, gas exchange, yield, yield contributing parameters, and quality characteristics of rice crop. However, better performance in all attributes was found in the case of zinc-coated urea. Gas exchange attributes (photosynthetic rate, 30%, and stomatal conductance 24%), yield parameters like plant height (29%), tillers per plant (38%), spikelets per spike (31%), grains per panicle (42%), total biomass (53%), and grain yield (45%) were recorded to be maximum in rice plants treated with zinc-coated urea. The highest grain and straw nitrogen contents, grain protein contents, and grain water absorption ratio were also found in plants with zinc-coated urea applications. In irrigation practices, the anaerobic regime was found to be more responsive compared to the aerobic regime regarding rice growth, productivity, and quality traits. Thus, to enhance the productivity and quality of rice grown in anaerobic conditions, zinc-coated urea is best suited as it is more responsive when compared to other forms of urea.

“…Meng and Du (2013) showed that an appropriate N application rate could ensure that the rice canopy population reached a higher leaf area index. It was investigated in a study of rice that nitrogenous fertilizer, amended with bacteria, was responsible for the variation in the various biochemical activities ( Fatma et al, 2021 ). Breeding techniques are also under consideration in developing new varieties of field crops, particularly rice ( Darwish et al, 2021 ; Herawati et al, 2021 ; Rahman et al, 2021 ), with respect to enhanced nitrogen use efficiency ( Javed et al, 2022a , b ).…”

Rice is a staple food for more than 50% of the global population and it is one of the most valuable cereal crops. To fulfill the dietary requirement of the ever-growing world population, an increase in per-unit production of rice is direly required. In Pakistan, it stands as the 2nd in consumption after wheat, which is a staple food. A huge gap is observed between yield potential and actual yield of the aromatic rice cultivars at a farmer-field level. The significant limitations responsible for this gap are shortage of irrigation water, inappropriate application of fertilizers, less plant population, deficiency of micronutrients, and improper and poor plant protection measures. A field study was planned to assess the yield response and quality attributes of aromatic rice to three levels of zinc (Zn) and nitrogen (N) under three irrigation regimes (8-, 12-, and 16-acre inches) in the Sheikhupura and Sargodha districts of Pakistan. Irrigation treatments significantly influenced the growth, yield, and quality attributes; however, maximum improvement was observed by the application of irrigation at 12-acre inches. Among the Zn treatments, application of Zn at 10 kg ha–1 was observed to be more responsive to improving the growth and quality parameters of aromatic rice crops. In the case of N treatments, application of N at 140 kg ha–1 produced the maximum total tillers, as well as productive tillers per hill, spikelets per panicle, leaf area index, leaf area duration, crop growth rate, total dry matter, harvest index, kernel length, kernel width, and 1,000-kernel weight. Application of N at 140 kg ha–1 not only improved the growth attributes but also increased the net assimilation rate, photosynthetically active radiation, and radiation use efficiency, with respect to total dry matter and kernel yield. The maximum percentage of normal kernels and minimum percentage of opaque, abortive, and chalky kernels were also recorded by application of N at 140 kg ha–1. The outcomes of current experiments depicted that application of irrigational water, zinc, and nitrogen at 12-acre inches, 10, and 140 kg ha–1, respectively, are responsible to achieve maximum resource utilization efficiency, along with increased yield and quality of rice.
