Abstract
To study the effect of application of manures and different amino acids on
growth and quality of kalmegh, a pot experiment was undertaken during July -2010 to
October -2010 at the Department of Agricultural Chemistry and Soil Science, B.A
College Of Agriculture, Anand Agricultural University, Anand. The study was
conducted to understand the effects of different sources of nitrogen on yield and
chemical composition of kalmegh, to study the comparative effects of application of
amino acids (organic nitrogen) on alkaloid content of kalmegh and to suggest the
suitable combinations of organic and inorganic sources of nitrogen for quality and
better production of kalmegh. Different amino acids were tried here viz - aspartic
acid and glutamic acid the two acidic amino acids, tryptophan, a neutral amino acid
and arginine, the basic amino acid as alone and as their mixtures with and without the
inorganic fertilizer. Organic manures which are conventionally used for raising this
crop were also tried here for a better evaluation of the crop response to the application
of amino acids. In total it accounted to thirteen treatments with three replications
designed in CRD. A Recommended dose of nitrogen 75 kg ha-1 was adopted as per
the earlier work done by Patel (2009). Of this 50% dose was given on the day of
transplantation along with irrigation water except in the case of treatments where
complete organic manures were used to supply the nitrogen. In these two treatments
organic manures were mixed with the soil two weeks before transplantation. Rest
50% of the dose was divided into two splits, as 25% one month and other 25% two
months after transplantation. Periodic plant as well as soil samples was collected at
75 DAT. Final harvest was made at 100 DAT
