Abstract
Pot studies were conducted to observe the effect of indigenous plants such as Prosopis glandulosa, Cassia angustifolia, Azadirechta indica and Sphaeranthus indicus on the growth, yield & quality parameters of rice cultivar IRR1-6. Powdered form of indigenous plants (leaves and flowers) was incorporated @ 2000 kg/ha into the soils belonging to four cropping histories i.e. orchard, kallar grass, wheat & rice fields. Pots were arranged in RCB design with four replicates. The data were collected on growth, yield and grain and straw nitrogen contents. The plant treatments, applied to all the four soils resulted in diversified environments for the rice crop parameters. Variability however depended on the nature of soils used. Among the soils tested orchard and wheat soils were found to provide most favourite soil rhizosphare for rice growth in the form of good soil structural conditions & high organic matter contents. Treatment with P. glandulosa has a profound effect on parameters of rice growth and yield as compared to the other treatments. Among rice quality parameters grain and straw nitrogen contents were improved over the control due to the wild plants treatment under various soils.
