Effect of organic manures on soil physico-chemical properties of Ocimum sanctum under stone fruit based agroforestry system

Abstract

The study was conducted for two consecutive years during 2016 and 2017 at experimental farm of Department of Silviculture and Agroforestry, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan (HP) to evaluate the effect of different organic manures and their distance of application from tree trunk on soil physico-chemical properties under Peach and Apricot based agroforestry system. The experiment was laid out in randomized block design (factorial) consisting of seven treatments with three distance levels. The results revealed that among different organic manure treatments, FYM @ 25 t ha-1 significantly influenced the soil physico-chemical properties of Ocimum sanctum and recorded highest soil moisture (11.20% and 11.27%), electrical conductivity (0.29 and 0.29), organic carbon (2.35% and 2.12%), available nitrogen (354.97 and 255.42), available phosphorus (55.08 and 53.88) and available potassium (356.40 and 278.96) over control when applied at a distance of 1m away from tree trunk under peach and apricot based agroforestry system, respectively.
