The study investigates the effects of varying levels of vermicompost and recommended fertilizer doses on pearl millet yield in Rajasthan. Conducted in a randomized block design, the experiment included sixteen treatment combinations. Results indicated that applying 6 t/ha of vermicompost significantly increased grain yield compared to lower levels. However, key metrics such as dry matter accumulation and harvest index showed little variation across fertility levels. The highest economic return was achieved with 100% recommended fertilizer dosage without vermicompost.

Most athletes are familiar with, and have experienced anxiety and stress that reduces their performance. Heart rate variability (HRV) is a well-established non-invasive tool which can be used to study the effect of mental stress and anxiety on autonomic control of the heart rate. HRV technique teaches athletes how to self regulate these functions through diaphragmatic breathing performed at an optimal pace to ensure coherence between heart rate and respiration. HRV is used in sports to maximize emotional stability, focus, concentration, and physical coordination. This Book will help/guide the athlete about the effectiveness of HRV biofeedback training on the psycho-physiological performance of track athlete.
