A 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, L₃-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 higher soil moisture content at all growth periodical days. Yield attributes viz. number of spikes plant-1, number of capsules plant^-1, seed yield plant^-1, test weight (g), seed yield, stalk yield, biological yield, GMR, NMR and B:C ratio, oil% and oil yield were significantly highest recorded inland configuration treatment ridges and furrows (L₂) which was remained at par with treatment BBF with paired row planting (L₄) and found significantly superior over treatment flat bed (L₁) and treatment flat bed with paired row planting (L₃) at all periodical days and at harvest except 30 DAS.

Similarly Yield attributes viz. number of spikes plant^-1, number of capsules plant^-1, seed yield plant^-1, test weight (g), seed yield, stalk yield, biological yield, GMR, NMR and B:C ratio, oil % and Oil 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) at all periodical days and at harvest except 30 DAS.. In case of moisture content in soil was found non-significant all periodical stages.
