Abstract

The present investigation was carried out to study the effects of inorganic, organic nitrogen fertilizers and activators (Humic and Fulvic acid) on chemical composition and productivity of corn. This study was conducted at Shandweel Agricultural Research Stations, Sohag Governorate, Egypt, and is situated at 26.60 N latitude and 37.70 E longitude. Its altitude is about 70 m above mean sea level. Also, this study was performed during two successive summer seasons 2014 and 2015. The experiments were laid down in split-split plot design with four replications. The treatments were included mineral nitrogen application in three levels (i.e. 60, 90 and 120 kg N fed.-1), organic and bio fertilizer application (without organic and bio fertilizer, 10 m3 FYM fed.-1 and Microbeine inoculume) as well as foliar spray of humic acid (water spraying, humic and fulvic acid spraying). The obtained results revealed that the interaction effects of all factors under study were significant for all studied traits.

Highlights

There are different applications for chemical compounds found recently, and this thing is important and can encourage scientists for more useful work.[1-18]
The results indicated that application of nitrogen fertilizer levels significantly increase the 100-grain weight of maize, over those obtained by control
The results obtained showed that the interaction effects between nitrogen fertilizer levels and farm yard manure (FYM) or Microbeine gave significant increases in the 100-grain weight more than those obtained by control

Summary

Introduction

There are different applications for chemical compounds found recently, and this thing is important and can encourage scientists for more useful work.[1-18]. Humic acid and fulvic acid increase the length and weight of root, number of lateral roots and flow of sap through the vessels They improve the quality and quantity of crops such as wheat, maize, etc., via increasing cell division and growth of crops, seeds germination.[33]. The major problems facing farmers are the high costs of excessive manufactured fertilizers needed for plants These chemical fertilizers are considered as air, soil and water polluting agents during their production and utilization. The present research aimed to study the effects of inorganic, organic nitrogen fertilizers and activators (Humic and Fulvic acid) on chemical composition and productivity of maize to reduce the mineral nitrogen fertilizer applications and to reduce production costs
