Impact of Fertigation on Soil Nutrient Dynamics in Dalbergia sissoo tree plantations
Abstract: Fertigation allows the controlled placement of nutrients reducing fertilizer losses through leaching and minimize groundwater pollution. In fertigation Nutrient Use Efficiency (NUE) could be as high as 90% compared to 40-60% in conventional method of fertilizer application. Standardizing nutrient management with micro-irrigation system would require consideration to be contributed to soil nutrient dynamics. A field trial was conducted in Forest College and Research Institute, Tamil Nadu Agricultural University, Mettupalayam, Tamil …

Nuclear Hulthén potentials for F and G partial waves
Abstract: In the past few decades, several investigation have been made and at the same time a number of theoretical models have also been projected for the nucleon-nucleon scattering in the low and intermediate energy range. These phenomenological models involve large number of free parameters to be fitted to reproduce the physical observables. In contrast to these potentials a two-term four parameter nuclear Hulthén type interaction is proposed to describe the …
