EFFICIENCY OF NANOPOLYMER APPLICATION ON THE GROWTH, DEVELOPMENT AND YIELD OF SOYBEAN

Abstract

The current study was carried out to analyze the effects of agro-nanopolymer preparations application on the seed germination, seedling and root sprout lengths, growth, development, yield, and resistance to Fusarium wilt in Baraka and Selecta-302 soybean variety under laboratory condition. For encapsulation of soybean seeds and nanopreparation UZHITAN, nanochitosan, chitosan (initial), polymer metallocomplexes (PMCs) of copper and silver ions were used at various ratios for nanoascorbate chitosan, ascorbate chitosan, polymer metallocomplex (PMC) Cu2+:Ag 7:3 and PMC Cu2+:Ag 8:2 preparations,. Results of the study revealed a significant effect of these agronanoplymers on the studied soybean varieties; application of this nanoascorbate chitosan, ascorbate chitosan, polymer metallocomplex (PMC) Cu2+:Ag 7:3 and PMC Cu2+:Ag 8:2 showed 17 g, 14.6 g, 13.5 g, and 11.9 g weight of the 1000-grains respectively which was significantly higher than the Gaucho treatment. Further, these agronanoplymers also have a significant effect on the various yield attributes such as number of beans per plant, number of seeds per bean, and seed mass per bean. Application of chitosan and PMC agronanopolemers increased productivity by 4.5-6.1 kg/ha and 3.3-5.1 kg/ha, respectively, compared to the control. Also, the effect of these agro nanopolymer preparations on enzyme activity and protein content was studied in the current study. Among the various tested nanopreparation, the greatest effect on total soybean yield was observed when seeds were treated with nano ascorbate chitosan. All nanopreparation treated seeds has a significant effect on the accumulation of macro and micronutrient accumulation in Soybean seed and except few one rest are the superior to the control and UZHITAN.
