“…1. As expected, each homeologues gets downregulated especially in case of chronic stress (Botella et al 1993;Golberg et al 1995;Santos et al 2019;Gao et al 2021), in fact, all the three sets of NR genes were downregulated under N-stress.…”

“…It has also been reported that the OsNR2 allele of the NR gene can increase the nitrogen use efficiency in rice (Gao et al 2019). It is well reported that this enzyme is responsive to nitrogen stress, mainly nitrate stress in different cereal crops including wheat (Botella et al 1993;Golberg et al 1995) (Botella et al 1993;Golberg et al 1995;Nathawat et al 2005;Santos et al 2019). Though an extensive study on NR gene has been conducted in Arabidopsis and Rice, understanding of this gene in wheat is limited.…”

Nitrate reductase (NR) is the key rate-limiting enzyme of the nitrogen (N) assimilation process in plants, which has not been characterized in bread wheat under nitrogen stress, especially with respect to their homeologues. Total 9 NRs were identified and classified into 3 groups, which showed a close relationship with different wheat ancestors. The occurrence of N-responsive cis-acting regulatory elements like MYB, MYC, G-Box and GATA-motif confirmed their N-responsiveness. Expression of all the three groups of NR under N-stress revealed NR 6-1ABD group to be the most N-responsive, which was characterized further in detail. The study was carried out in two genotypes contrasting for their N-responsiveness (HD 2967: Highly responsive to applied N, and Choti Lerma: Less responsive to applied N) selected on the basis of field evaluation. Homeologous differences within a genotype were found much more than the genotypic differences of a specific homeologue coding sequence. Among the three homeologues, though NR 6-1D homeologue was found most responsive to N-stress, the contribution was maximum for this homeologue followed by NR 6-1A and least by NR 6-1B. We found that the expression of homeologues was linked to the presence of N-responsive cis-elements. All the homeologues of NR 6-1 in Choti Lerma were found less responsive to N-stress, in comparison to HD 2967, which might also be linked to N-use efficiency. Homeologous expression of NR 6-1ABD revealed negligible contribution of B-homeologue to N-stress. Homeologous differences of NR 6-1ABD was found much more than the genotypic differences. Hence, our study on wheat NR will be helpful in manipulating the specific homeologue of the NR gene in the future.

“…The synergistic relationship between N and Mo reported by Marschner (2011) and verified by Imran et al (2019) for wheat, and by Santos et al (2019) for sugar cane, was not observed in this study. The results suggest that the content of Mo in Conilon coffee was influenced by the acidity of the soil resulting from the doses of N, indicating that the effect of pH on the specific adsorption and lability of Mo, elucidated by Rutkowska et al (2017), has a greater influence on the absorption of Mo by coffee, outdoing the effects from ionic interactions.…”

“…Nitrogen sources such as NaNo 3 produced the highest of NRA compared to nitrogen sources of NH 4 Cl and Urea [21]. The increase in N accumulation in the root or leaf tissue by fertilization stimulated NRA in both leaves and roots 13 and 42%, respectively [22]. Mensah et al [23] that NPK fertilization (15:15:15) at a certain dose range significantly increased the number of leaves, plant height, and leaf area of the Punica granatum plant.…”

Aims: The objective of this study was to determine the optimal fertilizing method and NPK fertilizer dosage for plant physiology and nutmeg yield. Study Design: The experimental design was a completely randomized block design (CRBD) in a 4x3 factorial arrangement with three replicates. The first factor was four NPK fertilizer doses: 1, 1.5, 2.0, and 2.5kg NPK (15:15:15)/tree/year. The second factor was the manner of fertilizer application: (1) fertilized in spot, (2) fertilized in-furrow trenches trunked and (3) fertilized in hole. Place and Duration of Study: The research was conducted in Tobelo North Halmahera (1°44'45.3"-1°44'54.4" N, 127°59'54.4"-127°59'53.2" E), North Maluku, Indonesia from January 2019 to May 2020. Methodology: The nutmeg trees used was 30 years old. The population of trees plants in the study area was 40 trees. Observation parameters on leaves are chlorophyll a, b and total, nitrate reductase activity (NRA), N, P, K, proline content, number of young and old fruits. Results: The fertilization treatment with the fertilizer application method into the crack/hole fertilizer with a dose of 2.5 kg NPK significantly produced high levels of chlorophyll a, chlorophyll b, total chlorophyll of leaves and old fruit. The number of old fruits is positively correlated with chlorophyll a content (0.615*), chlorophyll b (0.663*), total chlorophyll (0.634*) and number of young fruits (0.748 **). The application of fertilizer hole produces plants that recover quickly from drought stress, as evidenced by the highest proline content. Conclusion: NPK fertilization using the hole method and at doses of 2.0-2.5 kg/tree/year are recommended for improving plant physiology and yield.
