This study was undertaken at the private Farm, Bani Mazar District, Minia governorate. during the two seasons of 2020 and 2021. The aim of this study was to investigate the effect of irrigation water salinity, mineral and biofertilization [effective microorganisms (EM) and Azotobacter chroococcum bacteria (AC)] treatments, as well as, their combinations on the root growth and some chemical constituents of bermudagrass (Cynodon dactylon, L.), grown in sandy soil. Results showed that the root growth parameters i.e., root length and fresh and dry weights/unit were enhanced with the low and medium levels of salinity (3000 and 6000 ppm), while, they decreased with the high level of salinity (9000 ppm) compared with control, in the third cut during both seasons. On the other hand, all salinity treatments increased Na, Cl, Ca (% in the dry herb) and proline content (in fresh weight), and decreased photosynthetic pigments as well as NPK %. All used mineral and/or biofertilization treatments significantly increased root length and fresh and dry weights/unit comparing with control treatment in 3 rd cut, except AC for root length and EM and AC in case of fresh and dry weights/unit, with the highest values that were obtained due to 100% mineral NPK followed by EM + AC during both seasons. N, P, K and Ca % as well as photosynthetic pigments and proline content were increased due to application with any of the sub-plot treatments, while, Na and Cl were decreased. The best interaction treatments which mitigate the adverse effects of salinity (9000 ppm) were 100% mineral NPK followed by biofertilizer (EM + AC).

“…Our results revealed that cold stress significantly reduced the photosynthetic pigments in overseeded perennial ryegrass while fertilization on the other hand highly increased photosynthetic pigments (Tables 4, 7). The effects were so obvious that necrosis in the leaves occurred under control conditions and zero N. The enhanced chloroplastic pigments in response to N, P, and K, particularly N and then P were correlated with increased turf color, total protein, and photosynthesis in previous studies (Ihtisham et al, 2018;Jena and Mohanty, 2020;Ihtisham et al, 2021). N fertilization promotes the accumulation of chlorophyll as it is the major component of chlorophyll (Raza et al, 2022;Roy et al, 2022).…”

Overseeded perennial ryegrass (Lolium perenne L.) turf on dormant bermudagrass (Cynodon dactylon Pers. L) in transitional climatic zones (TCZ) experience a severe reduction in its growth due to cold stress. Primary plant nutrients play an important role in the cold stress tolerance of plants. To better understand the cold stress tolerance of overseeded perennial ryegrass under TCZ, a three-factor and five-level central composite rotatable design (CCRD) with a regression model was used to study the interactive effects of nitrogen (N), phosphorus (P), and potassium (K) fertilization on lipid peroxidation, electrolyte leakage, reactive oxygen species (ROS) production, and their detoxification by the photosynthetic pigments, enzymatic and non-enzymatic antioxidants. The study demonstrated substantial effects of N, P, and K fertilization on ROS production and their detoxification through enzymatic and non-enzymatic pathways in overseeded perennial ryegrass under cold stress. Our results demonstrated that the cold stress significantly enhanced malondialdehyde, electrolyte leakage, and hydrogen peroxide contents, while simultaneously decreasing ROS-scavenging enzymes, antioxidants, and photosynthetic pigments in overseeded perennial ryegrass. However, N, P, and K application mitigated cold stress-provoked adversities by enhancing soluble protein, superoxide dismutase, peroxide dismutase, catalase, and proline contents as compared to the control conditions. Moreover, N, P, and, K application enhanced chlorophyll a, chlorophyll b, total chlorophyll, and carotenoids in overseeded perennial ryegrass under cold stress as compared to the control treatments. Collectively, this 2−years study indicated that N, P, and K fertilization mitigated cold stress by activating enzymatic and non-enzymatic antioxidants defense systems, thereby concluding that efficient nutrient management is the key to enhanced cold stress tolerance of overseeded perennial ryegrass in a transitional climate. These findings revealed that turfgrass management will not only rely on breeding new varieties but also on the development of nutrient management strategies for coping cold stress.

“…The negative impacts of irrigation water salinity on plant height were stated by many authors such as Adavi et al (2006) The role of NPK fertilization in improving plant height was also mentioned by Ammar (2018), Ihtisham et al (2018), Jena and Mohanty (2020) and Ihtisham et al (2020) on Cynodon dactylon, L.…”

This study was undertaken at the private Farm, Bani Mazar District, Minia governorate. during the two seasons of 2020 and 2021 to investigate the effect of irrigation water salinity, mineral and biofertilization [effective microorganisms (EM) and Azotobacter chroococcum bacteria (AC)] treatments, and, their interactions on the vegetative growth of bermudagrass (Cynodon dactylon, L.), grown in sandy soil. Our results indicated that the vegetative growth traits (covering density, plant height, as well as, fresh and dry weights of clipping) were increased with the low level of salinity (3000 and 6000 ppm), while, they were decreased with the high level of salinity (9000 ppm) comparing with control treatment, with significant differences in some cases, in the three cuts during both seasons. The mineral and biofertilization treatments significantly increased the previous parameters compared with the control treatment, except some treatments (EM or AC) in 2 nd and 3 rd cuts with the highest values which were obtained due to 100% mineral NPK followed by biofertilizer (EM + AC), without significant differences in some cases, in the three cuts during both seasons. The interaction treatments were significant for all vegetative growth traits in the three cuts during both seasons. The best interaction treatments that mitigate the adverse effects of salinity (9000 ppm) were 100% mineral NPK followed by biofertilizer (EM + AC).
