Effect of Silica, Bio-Organic Fertilizers, and Spraying of Nano-Titanium and Nano-Cobalt on the Growth and Yield of Rice

Abstract In order to evaluate the response of rice plant (Anber 33 cultivar) fertilization with silica, bio-organic fertilizers and spraying nano-titanium nano-cobalt on some growth indicators yield crop Anber cultivar, The field study was conducted in Al-Tali’a district (boycott 41 - Al-Hussainiya) Babylon province, Iraq. for period from 15/6/2021 23/11/2021.The experiment according a randomized complete block design (RCBD).The treatments were randomly distributed simple one-way experiment, where silica fertilizer added at two levels (0 300 kg ha-1), as well 1000 ha-1).While nanomaterial’s represented by dual sprays nanomaterials concentration 100 mg L-1 each, so number 16 three replicates. results statistical analysis Duncan’s test showed that combined effect (silica + spray nano-titanium) recorded highest height (122.0) cm, chlorophyll index (40.97) SPAD, Netting percentage (70.20)%, spray). increase biological (16.25) Mg ha-1, treatment doul nano-materials) grain (4.43) ha-1 harvest (29.69)%, weight grains (20.90) g. agronomic efficiency (4270.8) kg-1.
