Abstract: Plants inhabit a range of soil and climate type for the growth. However, cultural practices make exotic species also inhabit a different soil and climate. With the idea of studying the requirement of a mangrove plant from the soil, a variety of soil including its native soil brought from different provinces (U.P., A.P., Uttaranchal) and provenances of U.P-Polluted, Irrigated, Roadside were studied for their physical and their nutrient properties initially and after the growth of the Rhizophora mucronata. Similarly in artificially made combination of soil to math with the area close to the coal fields, a study was carried out after growing a pulse crop. Barren soil of Uttaranchal with minimum organic matter, CEC, WHC, Moisture% and Total N2 exhibited best growth of Rhizophora mucronata in Meerut climate (35°C,60% RH). It also exhibited maximum Na+ uptake by the plant whereas, the plant did not take up Na+ from mangrove soil. Rest of the soil extracted out Na+ from the seedling in the form of leachates. The normal irrigated soil initially at pH 8.0, after growth of a pulse crop Pisum sativum, lowered down in pH with additional CEC in contrast to the previous observation and also lost organic matter by 50%. The study throws light on regeneration of abandoned and degenerating lands.
Key words: Rhizophora mucronata, Pisum sativum,Soil-climate regime and Salinity.
