Growth and Yield Response of Sunflower to Organic Amendments in Aridisol

Abstract

A round the globe as population is increasing with the passage of time so dietary habits of individuals is also changing. Demand for food, fuel and feed is increasing associated with urbanization so there is huge pressure on agriculture to combat this type of situations ( Jouffret et al., 2011). In Pakistan agriculture is the occupation through with 70 % of the population is involved directly or indirectly but still Abstract | Phosphorus (P) is a limited natural reserve and a major limiting factor for global crop production. The adverse soil biogeochemical characteristics of alkaline-calcareous soils make P the least available macronutrient. Therefore, alternative P source such as rock phosphate (RP) can offer a promising choice for sustainable P supply under P stress environment. A pot research was executed to explore the response of sunflower (Helianthus annuus L.) to sparingly soluble P sources grown under P deficient environment at research area, College of Agriculture, University of Sargodha during 2018. The experiment was laid out in a Completely Randomized Design (CRD) with eight treatments replicated thrice.
