Comparative efficacy of different farmyard manure sources on growth and yield of castor (Ricinus communis L.) 

Abstract

A field experiment was conducted at Castor-Mustard Research Station, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar in the North-Gujarat Agro-climatic region during kharif season of 2015-16. Results revealed that the plant height, 100 seed weight and oil content was recorded marginally higher with application of heap method FYM before one month of sowing and remains as pile for 15 days than incorporation into soil while length of main spike and seed yield of castor was registered higher under application of pit method FYM before one month of sowing and remains as pile for 15 days than incorporation into soil. Nutrient composition in FYM at the time of incorporation and soil fertility status after harvest of crop was also unaffected due to various treatments.
