Abstract:
An experiment was conducted during kharif season of the year 2017-18 at Agronomy Instructional Farm, C. P. College of Agriculture, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar to study the “Effect of farm yard manure and nitrogen on growth, yield and economics of castor (Ricinus communis L.).” Growth, yield attributing and yield of castor like plant height at 60, 120 DAS, at harvest, number of branches per plant, length of main spike, number of capsules/main spike, number of spikes/plant, seed yield/plant, seed yield and stalk yield were significantly increased with application of FYM prepared by pit method (M₂). Treatment M₂ (pit method) realized the highest net return with benefit: cost ratio. With regard to effect of different nitrogen management treatments on castor, all the growth and yield attributes such as plant height, number of branches per plant, length of main spike, number of capsules/main spike, number of spikes per plant, seed index, seed yield/plant, seed yield and stalk yield showed significant improvement due to application of 100% RDN + bio NPK consortium (N₃) which remained at par with treatment N₄ (75% RDN + bio NPK consortium) except plant height. The highest net realization and BCR were obtained under 100% RDN + bio NPK consortium (N₃) followed by treatment N₄ (75% RDN + bio NPK consortium).
