Nanotechnology is an emerging technique that helps in solving the biotic and abiotic agricultural issues leading to enhance crop productivity. Therefore, it was hypothesized to check the effect of Qiangdi 863 nano synergids biological-assisted growth apparatus and nitrogen, phosphorous, and potassium (NPK) fertilizers improving rice germination, early growth, physiology, and yield. An experiment was performed on five rice varieties for three consecutive years (2017-2019). The nanosynergids-treated water (NTW) significantly improved the speed of germination (25.3, 35.6, and 32.3%), final emergence percentage (100%) and seed emergence energy percentage (80, 95, and 90%), radical (1.25, 1.7, and 2.35 cm) and plumule growth (1.29, 1.24, and 1.66 cm), soil plant analysis development (46, 45, and 47), antioxidant enzymatic activities, such as catalase activity (34,376 μgFW h, 33,264 μgFW h, and 34,453 μgF W h), superoxide dismutase (18,456 μgF W h, 19,445 μgF W h, and 19,954 μgF W h), peroxide (745 UgF W, 734 UgF W, and 752 UgF W), production and declined malondialdehyde (4.5 μmolgF W, 5.1 μmolgF W, and 4.2 μmolgF W) for all years respectively in KSK 133. The application of nano-treated irrigated water enriched the biomass of rice seedlings. The overall nano synergid treatments successfully enhanced the endogenous hormones as salicylic acid (6,016.27 p mol/L, 5823.22 p mol/L, and 5922.12 p mol/L), jasmonates (JA) (5,175.6 p mol/L, 4231 p mol/L, and 5014.21 p mol/L) brassinosteroids (BR) (618.2 p mol/L, 546.83 p mol/L, and 582.1 p mol/L) quantification and yield 1000 grain weight (22.3, 22, and 23.2 g) of KSK 133. Hence, the overall results proved that NTW could effectively enhance the early growth and yield of rice varieties.
纳米技术是一种新兴技术，有助于解决生物和非生物农业问题，从而提高作物产量。因此，我们进行了一项研究，以检验强地863纳米增效剂生物辅助生长设备与氮、磷、钾（NPK）肥料对水稻发芽、早期生长、生理特性和产量的影响。连续三年（2017 - 2019年）对五个水稻品种进行了实验。纳米增效剂处理水（NTW）显著提高了发芽速度（分别提高了25.3%、35.6%和32.3%）、最终出苗率（100%）和种子出苗能量百分比（分别为80%、95%和90%）、胚根长度（分别为1.25厘米、1.7厘米和2.35厘米）和胚芽长度（分别为1.29厘米、1.24厘米和1.66厘米）、土壤植物分析发展指数（分别为46、45和47）、抗氧化酶活性，如过氧化氢酶活性（分别为34376μgFW/h、33264μgFW/h和34453μgFW/h）、超氧化物歧化酶（分别为18456μgFW/h、19445μgFW/h和19954μgFW/h）、过氧化物酶（分别为745UgFW、734UgFW和752UgFW），并降低了丙二醛含量（分别为4.5μmol/gFW、5.1μmol/gFW和4.2μmol/gFW），这些结果在所有年份的KSK 133品种中均有体现。应用纳米处理的灌溉水增加了水稻幼苗的生物量。总体而言，纳米增效剂处理成功提高了内源激素的含量，如水杨酸（分别为6016.27pmol/L、5823.22pmol/L和5922.12pmol/L）、茉莉酸（JA）（分别为5175.6pmol/L、4231pmol/L和5014.21pmol/L）、油菜素内酯（BR）（分别为618.2pmol/L、546.83pmol/L和582.1pmol/L），并提高了KSK 133品种的产量和千粒重（分别为22.3克、22克和23.2克）。因此，总体结果证明，NTW可以有效提高水稻品种的早期生长和产量。
