abstract
An experiment was conducted to examine the response of five different organic manures viz., Farmyard manure, Vermicompost, Castor Cake, Poultry manure, Neem cake as a source of nitrogen with or without chemical fertilizers in randomised block design with four replications during the kharif season of the year 2016. The results revealed that the significantly minimum days taken for first cutting at 20 cm height (23.25) and third subsequent cutting (44.00) at 20 cm height was recorded with treatment 20% N from Castor Cake + 20% N from Vermicompost + 30% N from Poultry manure + 30% N from FYM(T₉). The significant minimum days taken for fourth subsequent cutting (57.75) at 20 cm height was recorded with both treatments20% N from Castor Cake + 20% N from Vermicompost + 30% N from Poultry manure + 30% N from FYM(T₉) and 25% N from Poultry manure + 25% N from Neem cake + 25% N from FYM + 25% N from Vermicompost(T₈).Whereas, the effect of different sources of organic nitrogen was not found significant difference with respect to days taken for second cutting. The total number of cuttings is equal in all the treatments. The significantly maximum yield of first cutting (443.74g), second subsequent cutting (444.64g), third subsequent cutting (441.52g) and fourth subsequent cutting (442.97g) at 20 cm height was recorded with treatment 20% N from Castor Cake + 20% N from Vermicompost + 30% N from Poultry manure + 30% N from FYM(T₉). The maximum yield per plot (1.773 kg) and yield per hectare (101.02q) was recorded with treatment 20% N from Castor Cake + 20% N from Vermicompost + 30% N from Poultry manure + 30% N from FYM (T₉).
