Abstract:

A review study on plant population was done to assess the optimum population for improved grain yield and biological yield. The main perspective of this review study to evaluate the different planting population and to recommend it for future application. The increasing consumption of maize contributes a prominent place in economy of agriculture. The significance of planting density as a feature defining yield and growth has remained well recognized for the key areas of production of maize. Defining maize density reaction is a frequent part of study but it is unreliable across management practices and diverse environment. The grain yield of maize rise from 10.1 to 10.8 t ha-1 as population rise from 59000 to 89000 plants ha-1. The grain yield of maize normally reveals a quadratic comeback to planting population with a rise through a series of lower populations, a steadily reducing amount of yield increase comparative to population rise and lastly a yield plateau at certain reasonably higher populations of plant. Planting density influenced generally maize growth parameters in most promising growth condition and therefore it is measured as a vital aspect to regulate the range of interplant competition. Optimal planting density enlarged number of grains per cob, 1000-grain weight and eventually improved maize grain yield. This paper has reviewed the research work performed by numerous scientists in Pakistan and abroad.
