Integrated Nutrient Management of Organic and Bio-Fertilizer to Enhance Maize Production

Integrated nutrient management (INM) is the concept of using a combination of organic, inorganic, and biological amendments to increase nitrogen use efficiency (NUE) and reduce nutrient loss by synchronizing crop demand with nutrient availability in soil. In order to produce more food with limited space, farmers utilize several techniques. One of the best techniques is application of different types of organic and biofertilizers in soil in integrated nutrient management system and consequently maintain the soil nutrients level. It allows plant to grow, flourish, and keep the environment save. Importance of maize (Zea mays L.) crop is justified by its nutritious content especially because of the presence of high protein, minerals, vitamins and other energetic nutrients. In Egypt, maize production is insufficient, so various strategies have been developed to improve its production. In order to study the promoting effect of organic and biofertilizer on growth and yield of maize plant, a field experiment was conducted in Wadi El-Rayan, Fayoum Governorate, Egypt, during the two successive seasons of 2014 and 2015 to study the impact of organic or/and bio-fertilizer on growth, yield and its components and some chemical contents of two maize cultivars. The present study indicate that organic or/and bio-fertilizer had a positive effect on growth parameters. Yield and its components characters i.e. plant height (cm), number of rows per ear, length and diameter of ear, grain and straw yield per plant (g), seed index, grain, straw and biological yields (ton/fad.) of maize were also enhanced with organic or/and bio-fertilizer application. There were significant differences between two maize cultivars in growth parameters, yield and its components expect harvest index. The highest values of number of rows per ear (23.37), length of ear (22.517 cm ), diameter of ear (6.36cm ), grain yield per plant (151.67g) and straw yield per plant (262.33g) were recorded in High tech-2031 cultivar fertilized under 10 ton/fad. pigeon manure + foliar application of yeast bread. High tech-2031 cultivar fertilized with 10 ton/fad. pigeon manure + foliar application of yeast bread produced the highest value of carbohydrate and protein % in the grains.
