Effects of Different Organic Applications on Growth and Yield of Raphanus sativus (Raddish)

Radish is an edible root vegetable belonging to the Brassicaceae family. It is a vegetable that matures quickly and is simple to grow. More farmers are switching to use of organic manure as a result of rising knowledge of the risks associated with chemical fertilizers. A field experiment was conducted at the University of Colombo Institute for Agro-Technology and Rural Sciences in Hambantota, Sri Lanka, to evaluate the effects of several organic preparations on the growth and yield of radish. Thirteen treatments were replicated four times following RCBD design. Different organic preparations namely Newly Modified Panchagavya (NMPG), fish tonic, compost tea and a commercially available preparation of Crop Master were used in various concentrations based on the previous research findings and recommendations. Water was applied as a control. Data on plant height, number of leaves, leaf length (cm), leaf width (cm), fresh leaf weight (g), fresh root weight of plant and total yield per treatment (Kg/ha) were recorded and analyzed statistically using ANOVA in SAS 9.1.3 package. The treatment means were compared using DMRT at 5% significance level. The results revealed that, application of NMPG had a significant higher effect on most of the tested parameters. Further, 4% of the NMPG showed better values compared to other concentrations. It was followed by the 3% and 2% of NMPG. Compost tea and crop master followed values next to NMPG. Based on the present findings it can be concluded that, Newly Modified Panchagavya can be used as organic application to cultivate Radish plants with a better growth and yield to obtain potential yield of radish.
