Abstract

For effect of spacing and nitrogen on castor (GAC 11) grown in heavy black soil of middle Gujarat experiment was carried out at Narmada Irrigation Research Project, Anand Agricultural University, Khandha, Vadodara (Gujarat) during the years 2019-20, 2020-21 and 2021-22. The experiment was laid out in split plot design with three replications. Significantly the highest plant population was recorded under treatment S1 : 60-120-60 cm (Paired row). Growth and yield attributes of castor were remain unaffected due to the different spacing treatments, while, significantly the highest seed yield of castor was recorded under treatment S1 : 60-120-60 cm. Under nitrogen levels treatments, significantly the highest growth and yield attributes of castor like, plant height, number of branches per plant, number of spike per plant, main spike length and number of capsules per main spike and seed yield of castor were recorded under treatments N3: 100 kg/ha which was statistically at par with treatment N2: 75 kg/ha. Significantly the highest seed yield of castor was recorded under treatment S2N3 which was statistically at par with treatments S1N1, S1N2, S1N3, S2N2 & S3N3 ,while interactions effects were found non-significant with respect to growth and yield attributes. Maximum net realization and BCR were recorded under treatments S1N2, S1N3, S2N2 & S2N3, while, low cost of cultivation was found under treatment S1N1.
