dc.description.abstractABSTRACT The present investigations entitled “Nutrient optimization for growth and yield of Silybum marianum under peach based agroforestry system” was carried out at the experimental field of Department of Silviculture & Agroforestry,Dr. Y.S. Parmar University of Horticulture and Forestry, Nauni, Solan (H. P.) during 2013-2014. The experiment was laid out in randomized block design (factorial) comprising of peach var. nectarinaplanted at a distance of 9 m x 4 m and open field condition, under which milk thistle cropwas grown with five integrated fertilizer doses viz., T 1 (RDF), T2 (75% RDF + 25% VC), T3 (50% RDF + 50% VC), T4(25% RDF + 75% VC) and T 5 (100% VC). The plot size was 4 m x 2 m and spacingof 60 cm x 60 cm was maintained for milk thistle. The findings indicate that the effect of different fertilizer doses on growth and yield parameters viz., plant height (cm), leaves per plant, branches per plant, thistles per plant, LAI, root-shoot ratio, total biomass production (q ha -1 ) , yield (q ha -1 ) of milk thistle was significant. The peach trees had a positive effect on growth and yield performance of Silybum marianum and were found healthier and more thriving underneath peach than in sole cropping system. Among the different doses of fertilizers tried, T3 (50% Recommended dose + 50%Vermicompost) was found to be most efficient. The use of chemical fertilizers + organic manures has been found to be more efficient than inorganic as well as organic fertilizers alone. Different doses of chemical fertilizers and organicmanures are found to have influence on soil pH, EC, organic carbon, available N, P and K in thesurface soils. Soil chemical parameters viz., OC, available N, available P, available K showed maximum value in treatment T 3 (50% RDF + 50% VC). However, pH and EC was reported maximum intreatments T4(25% RDF + 75% VC) and T 1(RDF) respectively. Based on the economic returns, it was found that T1(Recommended doses of fertilizer) gives more profit in terms of monetary value since the inorganic fertilizers are cheaper as compared to organic fertilizers. But on contrary, the use of organic fertilizers improves the soil physico-chemical properties. Hence, from the present investigation it can be concluded that milk thistle can be successfully grown under peach based agroforestry system.en_US
