Abstract

The objective of this research was to evaluate the performance of different types of summer green manures in conventionally used soil. This research project was carried out in the district of Concepción (Paraguay). A Randomised Complete Block Design (RCBD) was used, consisting of four treatments and five repetitions. The treatments were Mucuna pruriens (T1); Canavalia ensiformis (T2); Dolichos lablab (T3) and Cajanus cajan (T4); each experimental unit had an area of 10 m2. The measurements that were evaluated were the green mass of weeds at 60 and 90 DAE, and the production of green mass and dry mass by each of the evaluated varieties of green manure crops at 90 DAE. The results were analysed using the Tukey Test at the 5% level of probability. The results that were obtained show that there were differences in the production of green mass: the biggest production was shown by T2 with 27.6 mg ha-1. The biggest producer of dry mass was T4 with 7.06 mg ha-1. Key words: Cajanus cajan, Canavalia ensiformis, Dolichos lablab, Mucuna pruriens. &nbsp

Highlights

The use of leguminous species as green manure for the improvement of soil through the incorporation of large quantities of organic material, whether in the form of green matter or crop stubble, is a common practice and recommended for the improvement and maintenance of the organic material content and productivity of soils in almost all of the world’s production regions.Green manures are cultivated plants that provide benefits to the soil, generally during the flowering period, with the aim of achieving agronomic improvement

Summary

Introduction

The use of leguminous species as green manure for the improvement of soil through the incorporation of large quantities of organic material, whether in the form of green matter or crop stubble, is a common practice and recommended for the improvement and maintenance of the organic material content and productivity of soils in almost all of the world’s production regions. Green manures are cultivated plants that provide benefits to the soil, generally during the flowering period, with the aim of achieving agronomic improvement. They are grown between rows of crops in fruit plantations or between two main crops that are temporally separate in rotation. Bad practices for working the soil should be mentioned, as they do not favour the improvement of the physical, chemical and biological properties of soil
