The influence of fertilizer regimes and water deoths on clonal growth, phenology and chlorophyll content of scirpus grossus in paddy soil

Scirpus grossus L. is a principal rhizomatous weed in the rice fields, drainage and irrigation canals, river banks, abandoned rice fields and wasteland in Malaysia. This study describes the spatio-temporal growth patterns of aerial plant on fertilized and unfertilized paddy soils. The fertilizer app...
