Effect of Sources and Levels of Organic Manures on Growth and Yield of Black Cumin

A field experiment entitled �studies on sources and levels of organic manures on growth, yield and quality of black cumin� was conducted at RIOF, UAS, GKVK, Bengaluru during rabi 2017. The experiment was laid out in RCBD with 12 treatments replicated thrice and the cultivar used was Ajmer Kalonji-1. Results revealed that application of 125 per cent N equivalent through vermicompost recorded significantly higher seed yield (723 kg ha-1). This was attributed mainly by enhanced growth parameters like plant height (55.33 cm), primary branches per plant (8.07), dry matter accumulation per plant (12.93 g) at harvest and leaf area per plant (351.08 cm2) at 60 DAS. Yield attributes like number of pods per plant (28.67), size of pods (3.00 cm2) and seeds per pod (87.33).
