Biocomposting of Anagallis arvensis and Impact of Prepared Vermicompost on the Growth of Tagetes erecta, Plant

In western Uttar Pradesh state of India, several crops viz. , Brassica campestris, Brassica nigra, Saccharum officinarum, Mentha piperita, Cicer arietinum (Chana), Lens esculenta (Masoor), etc. are grown in agricultural lands. In these crops, various kinds of weeds are also grown simultaneously, thereby reducing the crop yields, because most of the fertilizers using for growing crops, are absorbed by these weeds also. Anagallis arvensis is a common weed of these crops which appears and grown greatly during the winter season. Hence, in the present studies, an attempt was made, especially for the bioconversion of this weed into vermicompost and impact of prepared vermicompost on the growth of an ornamental plant, Tagetes erecta (marigold). Present study revealed that prepared vermicompost in different combinations have showed better results if it is used at 11 and 12, ratios of vermicompost + soil, and successively, lower in 13, 31, and control (only soil) media. The results were discussed in the light of physico-chemical parameters (PCPs) of different experimental media, shoot length and total number of flowers of Tagetes erecta and data available.
