Abstract

Considered an agricultural input by the Ministry of Agriculture and Supply, homeopathy has been increasingly used in agriculture, especially in plants. It is an important technology to be adopted to reverse a framework of saline stress, because since the current procedures are little known, have hight costs and resources are not renewable. The present study aims to evaluate the effect of the homeopathic preparation Natrum muriaticum (Nat-m) on agronomic performance and physiological parameters of cherry tomatoes submitted to saline stress. The statistical design was a completely randomized design with eight treatments and five replications. The treatments consisted in the application of Nat-m 3cH, 5cH, 7cH, 9cH, 11cH, 13cH and two controls: etanol 70% and distilled water. They were conducted in a greenhouse and the treatments were applied weekly. Satisfactory results were observed with the applications of Nat-m 11cH and 13cH, with a significant increase in the characteristics such as height, diameter of the lap, number of leaves, number of flowers per cluster, number of fruits, fresh fruit mass, as well as on the productivity of tomato plants. Lower averages of the proline content were obtained with the application of these homeopathic preparations, this response may be associated with the osmotic adjustment promoted by the use of ultradiluitions. Natrum muriaticum positively affected the vegetative and reproductive development of cherry tomato plants submitted to saline stress.

Highlights

Salinity restricts growth by osmotic effect, water unavailability, toxicity, and/or nutritional disorder by altering the morphology, structure, and metabolism of plants, thereby inducing stress that affects plantRev
The response of plants to salinity conditions is related to the expression of several genes (ZHU 2001) as well as salt tolerance levels that depend on the concentration and nature of the dissolved salts, climatic factors, water absorption, and plant nutrition
Soil correction was performed with limestone and corral-tanned manure (30 t ha-1, converted to the pot volume), and a sample was sent to the FCA/UNESP Soil Fertility Laboratory for chemical analysis (Table 1)

Summary

INTRODUCTION

Salinity restricts growth by osmotic effect, water unavailability, toxicity, and/or nutritional disorder by altering the morphology, structure, and metabolism of plants, thereby inducing stress that affects plant. The recovery of saline or alkaline soils facilitate chemical, physical, and biological conditions that guarantee seed germination, plant growth, and economic production. Homeopathy is one of the technology options that facilitate the development of plant species in highsalinity conditions. The response of plants to salinity conditions is related to the expression of several genes (ZHU 2001) as well as salt tolerance levels that depend on the concentration and nature of the dissolved salts, climatic factors, water absorption, and plant nutrition These factors may be different based on the species (MOURA et al 2003). This study evaluates the action of Nat-m on the agronomic performance and physiological responses of cherry tomatoes subjected to saline stress, to identify a possible alternative facilitator for the development of plants in expropriated environments
