Abstract

The aim of this study was to evaluate the effect of temperate climate plant species and two different types of fertilizer on the yield components related to summer maize crop productivity in an area with a history of 5 years of soybean/black oat succession cropping in a no-tillage system in ArenitoCaiua, Northwestern Paraná State, Brazil. The experiment was conducted in split blocks, with 6 blocks and 16 treatments (8 winter crops and 2 types of fertilizer). The maize hybrid used was DKB 390PRO. The following yield components were evaluated: plant height and height of first-ear insertion; final plant population; ear length and diameter; number of rows per ear, number of grains per row and number of grains per ear; weight of 100 grains and yield. It can be concluded that all succession systems are agronomically viable for maize production in the ArenitoCaiua region, in conjunction with adequate crop nutrition management, especially the winter common vetch/summer maize succession system fertilized with poultry litter which produced the best maize yield.   Key words: Green manure, poultry litter, commercial formulation, yield component, Zea mays.

Highlights

The production of maize (Zea mays L.) is one of the most important economic activities in Brazilian agribusiness due to its various forms of use, ranging from human and animal nutrition to high technology industrial uses, as well as its importance in social and economic terms

Summary

Introduction

The production of maize (Zea mays L.) is one of the most important economic activities in Brazilian agribusiness due to its various forms of use, ranging from human and animal nutrition to high technology industrial uses, as well as its importance in social and economic terms. The State of Paraná is the main Brazilian producer, accounting for 9.70% of the cropping area (768,000 ha) and 16.83% of domestic yield (6.05 million metric tons) (CONAB, 2012). The no-tillage system is one of the best alternatives for conserving natural resources, in conjunction with crop rotation and green manures that increase organic matter content, helping conserve and improve the structure of the soil (Calegari et al, 2006). These management strategies optimize fertilizer use since they increase biological activity in the soil (Calegari et al, 2006). The combined use of mineral fertilizers and green manure is aimed at conserving the environment while maintaining high crop yields (Arf et al, 1999)
