Assessment of Different Fertilizer Levels on Growth and Yield Returns of Coriander Crop. (Coriandrum sativum L.) cv- JD-1

Using chemical fertilizers or organic manures alone as amendments may be detrimental to the soil health and crop quality and neither of these alone can sustain productivity. Hence the combination of nutrients from different sources together in optimum ratio is a way forward to achive optimum returns and to protect soil health. In view of this a trial was conducted in coriander cv- JD-1 over winter 2012-13 at Horticulture research farm, Department of Horticulture, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur, Madhya Pradesh to evaluate the effect of organic manures and chemical fertilizers with different levels on growth and yield parameters of coriander. The experiment consists of four levels of organic manures viz Vermicompost 5 t/h, Vermicompost 2.5 t/h, Farm yard manure 20 t/h and Farm yard manure 10 t/h with two fertilizer levels 100 % RDF and 50 % RDF laid out in a randomized block design replicated thrice. The study shows that among the organic manures vermicompost 5 t/h and among the fertilizer levels RDF 100% showed maximum values for growth and yield parameters comparison to other levels of manures and fertilizer. Results in relation to interaction effect shows that vermicompost 5 t/h + 100 % RDF was superior over other treatment combinations. Highest gross income were observed with vermicompost 5 t/h + 100 % RDF and highest benefit cost ratio with farm yard manure 20 t/h + 100 % RDF.
