Abstract
Abstract The research aims to evaluate the response of rice plant to fertilization with NPK, NPK Organic fertilizers and spraying of nano-vanadium and nano-selenium in some growth and yield indicators of rice (Anber 33 cultivar).A field study was conducted in Al-Tali’a district (41 - Al-Hussainiya, south of Hilla city) Babylon province Iraq, for the period from 15/6/2021 to 26/11/2021.The experiment was conducted according to a randomized complete block design (RCBD).The treatments were randomly distributed according to a simple one-way experiment. The experiment was applied by adding NPK fertilizer at two levels (0 and 300 kg ha -1 ) and NPK Amino Humic Compound fertilizer at two levels (0 and 1000 kg ha -1 ).While the treatments of spraying with nanomaterials represented by spraying nano-vanadium and nano-selenium at a concentration (100 mg L -1 ) were two sprays, bringing the number of experimental units to 16 treatments. The results of the statistical analysis of Duncan’s test showed that fertilizing with organic acids fertilizer with nanomaterials gave the highest plant height, reaching (120 cm). While the combination (NPK+NPKOrganic+nano-vanadium) showed the highest chlorophyll index, which amounted to (40.80) SPAD. While quadruple combination treatment of (NPK+NPKOrganic +nano-vanadium+nano-selenium) achieved the highest values in biological yield (15.93 Mg.ha -1 ) and grain yield (4.30 Mg.ha -1 ) and harvest index (27.0%) Also, the single (NPK) treatment gave the highest weight of 1000 grains, which weighed (21.37 g).The spraying of nano-selenium and vanadium recorded the highest agronomic efficiency, reaching (1676.7 and 1468.7 kg kg -1 ) to spray nano-Va and nano-Se respectively, followed by the dual- combination of nano-materials, which amounted to (1202.7) kg kg -1 .
