The field experiment was conducted during rainy (kharif) season of 2017-18 at Experimental Farm, Agronomy Section, College of Agriculture, Latur. The experiment was laid out in Split plot design with three replications. The tremens comprised are Main plot treatment (Land configurations): L1- Flat bed – 90 cm × 60 cm, L2- Ridge and furrow – 90 cm × 60 cm, L_3-Flat bed with paired row spacing – (60 -120- 60 cm) × 60 cm, L4-BBF with paired row spacing – (60 -120- 60 cm) × 60 cm and Sub-plot treatments (Fertilizer levels) F1-75% RDF, F₂ - 100% RDF, F₃-125% RDF. The result indicated that the land configuration treatment ridges and furrows (L₂) recorded significantly increase growth and yield attributing characters and yield of castor viz. plant height, number of functional leaves plant^-1, number of branches plant-1, leaf area plant-1, total dry matter accumulation plant -1, number of nodes plant-¹, stem girth plant^-1, number of spikes plant-1, number of capsules plant^-1, seed yield plant-1, test weight, seed yield, stalk yield and biological yield and which was found significantly superior over treatment flatbed (L₁) and treatment flat bed with paired row planting (L₃) and remained at par with treatment BBF with paired row planting (L₄) at all periodical days and at harvest except 30 DAS.

Similarly growth, yield attributing characters and yield of castor was observed higher in application of 125% RDF treatment (F₃) and which was found significantly superior over 75% RDF treatment (F1), and found at par with 100% RDF treatment (F₂).
