Impact of Multiwalled Carbon Nanotubes for the Vegetative Growth and Yield Attribute of Wheat Triticum Aestivum L

Abstract

newline Present work entitled Impact of Multiwalled Carbon Nanotubes for the Vegetative Growth and Yield Attribute of Wheat (Triticum aestivumL.) has been conducted with the objectivesto synthesize, characterize the MWCNTs and to study their effecton the germination, seedling growth and the yield attributes of wheat crop. newlineSynthesis ofMWCNTs was madeby CVDmethod. Characterizations of MWCNTs were made by FESEM, XRD, Raman andFTIR and consequently a field experiment was conducted in RBD with three replicates at the farm land ofD.E.I. Dayalbagh, Agra.The MWCNTs were suspended directly in double distilled water by sonication in an ultrasonic bath. MWCNTssolution was prepared at four different concentrations i.e. T1(20µg/ml), T2(30µg/ml),T3(40µg/ml), T4(50µg/ml)along with itscontrol. newlineThe high yielding variety of test crop wheat was HD-2967.Various intercultural activities were performed asperneed of the crop. The time to time observations on vegetative growth parameters were taken from the each observation plot at 30, 60 and 90 DAS.Yield and yield attributes were also recorded accordingly. newlineIt has been observedthat Germination per unit area gradually increases as increases the dose of carbon nanotubes. T4 showed higher value in comparison to others. Hence carbon nanotubesshowed positive effect on the germination and growth of wheat.The effect of CNTs on wheat seeds was positively significant at 30, 60, 90 DAS. Number of tiller per unit area was found maximum in the T4 followed by T3 as compared to control. Hence the application of MWCNTs enhanced the vegetative growth gradually with the concentration. Yield attributes were also positively affected by the application of MWCNTs in different concentrations. Yield was also increased as the concentration increased i.e. more in the case of T3 and T4 in comparison to control and other lower concentrations of MWCNTs. newline
