Abstract :

Gandhinagar is the capital city of Gujarat State. The paper deals with the estimation of nutrients (pH, EC, N, P, K, Zn) in soil of different talukas of Gandhinagar district. This district has four talukas with 290 villages and 10 urban habitations in the district. For the study purpose, the entire district was divided into 20 sites. Five sites of each talukas were selected. Total 20 sampling sites were selected to collect samples. The study was carried for a period of 2 year (2011 to 2013). Soil samples were colleted and analysed for their parameters like pH, EC, Nitrate, Phosphorus, Potassium and Zinc (Zn) at monthly. Zn was recorded critical in Mansa and Dehgam taluka and quite low in Kalol taluka. The occurrence types and distribution of Amaranthus viridis L., Achyranthus aspera L., Trianthema portulacastrum L, Boerhavia diffusa L., Cyperus rotundus L., Cynodon dactylon (L.) Pers., Tridex procumbens L., Parthenium hysterophorus L., Euphorbia hirta L., Vernonia cinera (L.) Less., Digera muriata (L.) Mart., Cassia tora L., Chenopodium album L., Portulaca oleracea L. in the study area of Gandhinagar showed relations with the soil in which they occur.
