Abstract

A field experiment was undertaken in the post-Rabi season of 2019-2020 to reveal the response of greengram (Vigna radiata L.) to seed dressing and seed priming with nano molybdenum trioxide (MoO3). The experiment was laid out in randomized block design (RBD) consisting of 10 different treatments i.e., M0 (no seed treatment with Mo); M1 (seed dressing with Sodium molybdate @ 400 ppm); M2, M3, M4, and M5 (seed dressing with nano Molybdenum trioxide-MoO3 @ 50, 100, 200 and 400 ppm, respectively); and M6, M7, M8 and M9 (seed priming with nano MoO3 @ 50, 100, 200 and 400 ppm, respectively). Inoculation of greengram seeds cv. Shreya (IPM 2-14) with Rhizobium sps. was undertaken in all treatments as per the recommended practice, except in M0 (control). The MoO3 nanoparticles (NPs) synthesized from Ammonium molybdate through calcination at 600 0C for 5 hours indicated globular-shaped NPs of 68.55 nm in TEM and XRD. Nanopriming with MoO3 @ 200 ppm (M8) was most promising in recording significantly superior growth and yield attributing parameters and yield, whereas Mo (control) produced the least. Crop height, number of branches, root length, shoot dry matter, pods/plant and seeds/plant and root nodulation at harvest in M8 were 39.4% and 22.6%; 39% and 5.6%; 23% and 9.3%; 43.9%, and 16.3%; 28.2% and 5.3%; 28.1% and 0.8%, and 73.3% and 36.5% higher than M0 (control) and M1 (farmers’ practice), respectively. Superior growth and yield attributing characters in M8 treatment produced the highest grain and stover yield of 0.88 and 3.74 t/ ha that was 32.53% and 8.37%, and 35.5% and 14.7% higher than M0 (control) and M1 (farmers’ practice), respectively. Seed priming with nano MoO3 @ 400 ppm (M9) and seed dressing with nano MoO3 @ 400 ppm (M5) were of second and third order in recording grain and stover yield but M0 recorded the lowest among all the treatments.

三氧化钼纳米颗粒介导的种子引诱对青蒜（Vigna radiata L.）产量的影响

在 2019-2020 年后赤霉病季节进行了一项田间试验，以揭示青稞（Vigna radiata L.）对纳米三氧化钼（MoO3）拌种和种子处理的反应。实验采用随机区组设计（RBD），包括 10 个不同的处理，即M0（不使用钼处理种子）；M1（使用钼酸钠 @ 400 ppm 拌种）；M2、M3、M4 和 M5（使用纳米三氧化钼-MoO3 @ 50、100、200 和 400 ppm 拌种）；以及 M6、M7、M8 和 M9（使用纳米 MoO3 @ 50、100、200 和 400 ppm 引种）。除 M0（对照）外，所有处理都按照建议的方法给 Shreya（IPM 2-14）品种的青禾苗接种了根瘤菌。用钼酸铵在 600 0C 煅烧 5 小时合成的 MoO3 纳米粒子（NPs）在 TEM 和 XRD 中显示为 68.55 nm 的球状 NPs。用二氧化钼（MoO3）@ 200 ppm（M8）进行纳米微粒化处理最有希望获得显著的生长和产量属性参数及产量优势，而钼（对照）产生的效果最小。与 M0（对照）和 M1（农民做法）相比，M8 的作物高度、分枝数、根长、芽干物质、豆荚/株、种子/株和收获时的根瘤率分别高出 39.4% 和 22.6%；39% 和 5.6%；23% 和 9.3%；43.9% 和 16.3%；28.2% 和 5.3%；28.1% 和 0.8%，以及 73.3% 和 36.5%。与 M0（对照）和 M1（农民的做法）相比，M8 处理的优异生长和产量特征产生了最高的谷粒和秸秆产量，分别为 0.88 吨/公顷和 3.74 吨/公顷，分别高出 32.53% 和 8.37%，以及 35.5% 和 14.7%。用纳米氧化钼（400 ppm）拌种（M9）和用纳米氧化钼（400 ppm）拌种（M5）在谷物和秸秆产量方面分列第二和第三位，但在所有处理中，M0 的产量最低。
