The Quick Stats Database is the most comprehensive tool for accessing agricultural data published by NASS. Narrower row spacings and higher plant populations are trending in dry bean production. Interrelationship between population and factors affecting yield: The basic principle is that the optimum density of crop should be lower than normal under conditions of limited moisture supply. The mating or crossing of two plants or lines of dissimilar genotype is known as hybridization. As plant density increases up to a certain limits a crop will continue to respond to higher level of added nutrients provided moisture supply is adequate. Plant population will depend on the soil, climate, and the type of crop being planted.

However it is desirable to have plant density between 50 to 100 thousands ha. Plant density is an important agronomic factor that manipulates micro environment of the field and affects growth, development and yield formation of crops. Definition of Compost: Compost is defined in the Oxford Advanced Learner's dictionary as the process of mixture of decayed organic matter, manure, etc. In every dense crop, there is competition among plants results in mortality of some plants. Even small plots of land - whether rural or urban - growing fruit, vegetables or some food animals count if $1,000 or more of such products were raised and sold, or normally would have been sold, during the Census year. With increase in crop density, the height of plant increases instead of lateral spreads. 1984. .traditional agricultural societies.

Within certain limits, increase of Plant Population Density (PPD) decreases the growth and yield per plant but the reverse occurs for yield per unit area (Caliskan et al., 2007). Section 207(f)(2) of the E-Government Act of 2002 requires federal agencies to develop an inventory of information to be published on their Web sites, establish a schedule for publishing information, make those schedules available for public comment, and post the schedules and priorities on the Web site. Competition for light was indicated as an impor- tant element for the growth of dimension inequality (Weiner 1990). For example, Nielsen says that at a $5-per-bushel corn price, $200-per-bag seed would dictate a plant population of just over 29,000 an acre to "maximize marginal return." At the same grain market price, $375-per-bag seed would be best planted at a 27,500-per-acre rate.
