Impact of Sulphur Nanoparticles on Growth and Biological Yield of Groundnut-Mustard Crop Sequence Under Sandy Loam Soils of Central Gujarat

Abstract

In the present era of farming, the farmers were not using the secondary fertilizers for supplementing the sulphur nutrient and groundnut and mustard crops require the higher amount of sulphur. While, the traditional sulphur fertilizers have very low nutrient use utilization efficiency, moreover nano fertilizers have high nutrient use efficiency. So, the present experiment was conducted with using the different sources of sulphur. The existing experiment was conducted at Anand Agricultural university, Anand, in 2021-22 using completely randomized design with 11 treatments replication 4 times. The results reveal that the significantly higher plant height at 30 DAS was registered with the application of RDF + sulphur nanoparticles @ 4 mg S/kg (T10), than rest of the treatments. The significantly higher plant height, branches/plant and biological yield of groundnut-mustard cropping sequence was obtained with the fertigation of RDF + sulphur nanoparticles @ 3 mg S/kg soil, 50% at basal & 50% at 30 DAS (T9). It can be concluded that application of 3 mg S/kg soil, 50% at basal & 50% at 30 DAS can be an optimum dose of sulphur in pot experiment through fertigation under sulphur deficient soil.
