Promoting field emergence of Palmyrah (Borassus flabellifer L.) seeds through dormancy alleviation

Studies were carried to find out the effect of pre-sowing seed treatments to alleviate the dormancy of Palmyrah. A total of ten pre- sowing treatments viz., soaking in water for 24 h, soaking in 1% cow dung solution for 24 h and control (dry seeds) were given to fresh nuts of Palmyrah. At 4, 7, 12, 18 and 24 months after planting in the field, performance of seedlings were evaluated for field emergence, seedling height and the results revealed that seeds soaked in 1% cow dung solution followed by seeds soaked in 1% CaOCl2 (103 days). Seven months after sowing the seeds soaked in 1% CaOcl2 recorded the highest field emergence of 56% with high leave production per seedling (2.1) when compared to control. This study also confirms the effect of pre-sowing treatments on field emergence and frond production of Palmyrah nut which has dormancy.

Studies were carried to find the effect of pre - sowing seed treatments on field emergence and seedling growth of palmyrah. The seeds were subjected to water soaking for 24 hours, soaking in 1% and 2% of cow dung solution, KNO3, H2O2 and CaOCl2 for 24 hours and dry seeds served as control. 120 days after sowing the observations were made on days taken for initial emergence, field emergence (%) and 210 days after sowing the observations were made on field emergence (%), seedling height (cm) and number of leaves per seedling. The results revealed that seeds soaked in 1% cow dung solution for 24 hrs took 102 days for initial emergence followed by seeds soaked in 1% CaOCl2 for 24 hrs (103 days), 210 days after sowing the seeds soaked in 1% CaOCl2 for 24 hrs. recorded the highest field emergence of 56 % and more number of leaves/seedling (2.1) when compared to control. It is recommended that palmyrah seeds soaked in 1% CaOCl2 for 24 hrs enhance the germination, field emergence and seedling growth.

The experiment was conducted in post graduate Seed Testing Laboratory and Field Department of Genetics and Plant Breeding, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (U.P) during Rabi season 2020-2021, in order to standardize the suitable pre-sowing seed treatment for Lentil (K-75). Different pre-sowing seed treatments viz.,T0-Control (untreated), T1- KCL @1%, T2- KCL @ 3%, T3- KNO3 @ 1%, T4- KNO3 @ 3%, T5- Panchagavya @ 2%, T6 – GA3 @ 20ppm, T7 – Panchagavya @ 4%, T8 – GA3 @ 10ppm,T9 – Panchagavya @ 6%,T10 – Tulasi Leaf Extract @ 2%, T11 – Tulasi Leaf Extract @ 4%,T12 – Tulasi Leaf Extract @ 6% were evaluated by screening of 12 hour. It was found that all the pre-sowing seed treatments recorded the significant difference with that of control. In field condition highest field emergence percentage,yield and yielding attributes was found in T7 -Panchagavya @ 4%. Pre-sowing seed treatment with Panchagavya @ 4% followed by GA3 @ 10 ppm, Panchagavya @ 2%, KCL @ 1% significantly increased the germination and yielding attributes of Lentil. Pre-sowing seed treatments with Panchagavya (4%) and GA3 (10ppm) resulted in maximum increase in field emergence, vigour of Lentil seeds and found to be lowest in control seeds. Pre-sowing seed treatment that leads to a physiological condition that allows the seed to germinate more effectively and no costly equipment and chemical requirements could be used. Hence it is a simple method for overcoming weak germination and seedling establishment and helps to preserve agriculture and economical, non-toxic, eco-friendly sources.

Background: Paspalum scorbiculatum is an annual crop and has superior nutritional properties including high micronutrients, dietary fiber content and gluten free. It has low glycemic index (GI) carbohydrate diets help in prevention of Obesity, Diabeties and Cardiovascular diseases, etc. The current study was aimed to find out the suitable pre- sowing seed treatments for Kodo millet. Methods: During the Kharif season 2019- 2020 total of 12 pre- sowing seed treatments were subjected with Botanicals, Magnetic and Electric fields, Thermal (Hot water) treatments and to fix the best treatment based on Seed Quality and Morphological traits of treated seeds. Morphological traits play an major role in crop growth and development where as, the present investigation was carried out with farmer’s variety in field (RBD) design in 3 replications and laboratory (CRD) design in 4 replications in order to “Standardization of different pre- sowing seed treatments on growth, yield and yield attributing traits of Kodo millet (Paspalum scorbiculatum). Seeds were subjected to various pre- sowing seed treatments viz. (T0) control, exposure to Magnetic field at 100 mT, 200 mT, 400 mT for 15,30 and 45 min; exposure to Electric field at 50 mA, 100 mA, 150 mA for 5,10, 15 min. Treatment with botanicals cow dung (5 gm) and Datura leaf extract (2.5 ml) for 12 hrs; Thermal hot water treatment at 46°C and 50°C for 10 min. Result: Among all the treatments, T4-Magnetic field (200 mT) gave the best results in field and lab conditions of field emergence (98.610) and germination% (98.5), Magnetic field (400 mT) shown the good results and significantly higher values of all other yield (45.867, 78.833, 660.480, 165.120) and morphological traits as well as seed quality parameters like shoot length (86.925), root length (44.55), seedling length (13.131), vigour index- I and II (1267.138 and 5.058), fresh (0.343) and dry (0.0524) weight of seedlings and comparatively control (T0) was observed lowest to other treatments. As such, Magnetic treatment is quite effective for seedling establishment to overcome low germination and yield which helps in Qualitative and Quantiative seed production of Millets in sustainable agriculture.

Background: Impaired neuromuscular function after concussion has recently been linked to increased risk of lower extremity injuries in athletes. Purpose: To determine if National Football League (NFL) athletes have an increased risk of sustaining an acute, noncontact lower extremity injury in the 90-day period after return to play (RTP) and whether on-field performance differs pre- and postconcussion. Study Design: Cohort study, Level of evidence, 3. Methods: NFL concussions in offensive players from the 2012-2013 to the 2016-2017 seasons were studied. Age, position, injury location/type, RTP, and athlete factors were noted. A 90-day RTP postconcussive period was analyzed for lower extremity injuries. Concussion and injury data were obtained from publicly available sources. Nonconcussed, offensive skill position NFL athletes from the same period were used as a control cohort, with the 2014 season as the reference season. Power rating performance metrics were calculated for ±1, ±2, and ±3 seasons pre- and postconcussion. Conditional logistic regression was used to determine associations between concussion and lower extremity injury as well as the relationship of concussions to on-field performance. Results: In total, 116 concussions were recorded in 108 NFL athletes during the study period. There was no statistically significant difference in the incidence of an acute, noncontact lower extremity injury between concussed and control athletes (8.5% vs 12.8%; P = .143), which correlates with an odds ratio of 0.573 (95% CI, 0.270-1.217). Days (66.4 ± 81.9 days vs 45.1 ± 69.2 days; P = .423) and games missed (3.67 ± 3.0 vs 2.9 ± 2.7 games; P = .470) were similar in concussed athletes and control athletes after a lower extremity injury. No significant changes in power ratings were noted in concussed athletes in the acute period (±1 season to injury) when comparing pre- and postconcussion. Conclusion: Concussed, NFL offensive athletes did not demonstrate increased odds of acute, noncontact, lower extremity injury in a 90-day RTP period when compared with nonconcussed controls. Immediate on-field performance of skill position players did not appear to be affected by concussion.
