Abstract:
A field experiment was conducted at Castor Mustard Research Station, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar during the Kharif 2020-21 to investigate the “Effect of castor transplanting and different organic manures on growth, yield and quality of castor (Ricinus communis L.) Under North Gujarat agro climatic conditions”. The soil of the experimental area was loamy sand in texture, slightly alkaline in soil reaction, low in organic carbon, available nitrogen and available sulphur, medium in available phosphorus and available potash. The experiment comprised of main plot treatments of four levels of age of seedling (A₁: Two week old seedling, A₂: Three week old seedling, A₃: Four week old seedling and A₄: Normal sowing), four levels of source of manures (S₁: No compost, S₂: Vermicompost, S₃: FYM and S₄: Castor shell compost) was laid out in randomized block design with factorial concept with three replication. Castor variety GCH 8 was used as a test crop. The plant height at 60 DAS was found significantly highest (50 cm) with treatment of normal sowing while it was at par with transplanting of two week old seedling and three weeks old seedling. Number of leaves at 60 DAS was found significantly highest (16.28) with normal sowing while, it was found at par with treatment of two weeks old seedling. Number of effective branches plant^-1 was found significantly highest (17.95) with treatment of normal sowing, while it was at par with transplanting of three week old seedling. Significantly higher seed yield (3165kg ha^-1) was recorded with treatment of normal sowing, but it was found at par with treatment of three week old seedling and two week old seedling. Interaction effect of age of seedling and source of manures recorded significantly higher seed yield (3656kg ha^-1) with treatment three week old seedling + castor shell compost.
