Biophysical observation and XRD soil analysis for Rice Variety

Abstract

The supplementary function of organic manure in conjunction with chemical fertilizers plays a vital role in maintaining soil health, thereby potentially enhancing rice yield.A field trial was conducted in 2020 during the rice cultivation season in the kharif period at a farmer's field in Alwanneri village, Nanguneri Taluk, Tirunelveli district, Tamil Nadu. The study was designed following a Randomized Block Design (RBD) with seven treatments, three replications to assess various organic manures such as Farm Yard Manure (FYM), Vermicompost (VC), and Vegetable waste compost (VWC) at different combination and dosage levels of application (4.5 t ha^-1,11.5 t ha^-1, 17.5 t ha^-1) in comparison to a control plot without any manure amendment.The study focused on the impact of plant spacing on rice variety TKM 9, analysing plant growth and yield. Seedlings age under 25 days were transplanted with 30x 20cm spacing for six treatment and control plot. Data on plant height, Number of tillersand  leaf width were collected from 7 sampling plants in each plot. Results indicated significant effects of planting density and seedling age on plant height, number of tillers and grain yield. Soil samples were collected from random areas covering the entire area within each plot at (0-30cm) depth at before harvest and after harvest it is used for XRD soil morphology analysis.
