It is also of www.selleckchem.com/products/z-vad-fmk.html interest to report that calorie yield in maize is two and halftimes higher than that in paddy-rice [2]. In Bangladesh, the cultivation of maize has been gaining popularity in recent years. It is now becoming an important cereal crop for its high productivity and diversified use. The agroclimatic condition of Bangladesh is favorable for its cultivation all year round. However, the average yield of local maize in the country is comparatively low (1.06tha?1), whereas the newly released varieties have the potential to produce more than 5.2tha?1 [3, 4]. Agronomic practices such as seed rate, plant population and fertilizer management are known to affect crop environment, which influence the growth and ultimately the yield [5].

Optimum population nitrogen (N) levels should be maintained to exploit maximum natural resources, such as nutrients, sunlight, and soil moisture, to ensure satisfactory growth and yield. High density is undesirable because it encourages inter plants competition for resources. N has been found to be the most important nutrient for maize production [6]. Biomass production of a crop largely depends on the function of leaf area development and consequential photosynthetic activity [7]. Photosynthetic rate can substantially be increased with N-fertilization. Application of N-fertilizer has also been reported to have significant effect on grain yield and quality of maize [8]. Hardas and Karagianne-Hrestou [9] reported that 180kgNha?1 was optimum for maize, while Singh et al. [10] observed that application of 200kgNha?1 increased grain yield of maize.

However, a substantial percentage of applied N is also lost due to volatilization, leaching, and denitrification. Therefore, N should be applied in such a way that would maximize its utilization for grain production. There are some reports on N-management [6] and the optimization of population density per unit area [11] for the maximum harvest of maize. However, the relationship between maize forage yield and plant density is not well established. Maize producers require more information on how N-fertilization and plant density practices affect dry-matter yield and quality.Keeping the above information in view, the present study was conducted to (1) determine the growth and growth efficiency of maize at different levels of N-fertilizer and plant population and (2) determine the optimum N-fertilizer application and plant population density for the maize growing farmers.

We examined the plant height, light interception (LI), leaf area index (LAI), total dry-matter (TDM), grain yield (GY), and harvest index (HI) of maize plants in treated soils. In addition, soil-plant-analysis development (SPAD) values, dry-mass (DM), and harvest index (HI) of maize Carfilzomib plants were also evaluated.
