Abstract

This study was performed to examine the effects of different concentrations of magnetic nano-chitosan (MNC) and nano-Fe3O4 (NF) on the growth and yield of cucumber (Cucumis sativus L. cv. 'Negin'). The sizes of nano-particles were in the range of 20 nm to 50 nm, and their concentrations ranged between 10 to 100 mg L-1. The experiment was designed with nine treatments of MNC (10, 25, 50 and 100 mg L-1), NF (10, 25, 50 and 100 mg L-1) and one control treatment (iron chelate; IC: 60 mg L-1). The results showed that the foliar application of MNC and NF could improve yield and plant growth in cucumber, as well as iron chelate. The results of the present study suggest that the foliar application of nano-fertilizers similar to iron chelate could improve the plant growth and yield of the greenhouse cucumber. As regards toxicity of iron chelates, especially in high doses in the soil, the application of MNC may be safer in sustainable agriculture and even could be better than NF, because it has the combined effects of magnetism, chitosan and being nano-size.

Highlights

Cucumber is one of the main vegetables in Iran that is predominantly cultivated in plastic greenhouses it constitutes the fourth most important vegetable crop after tomatoes, cabbage, and onion in Asia (Eifediyi and Remison, 2010)
The obtained data revealed that foliar sprays with magnetic nano-chitosan (MNC) have similar effects with control treatment in terms of growth and yield of cucumber
According to Shafiee-Masouleh et al (2014), it seems that chitosan has a role to increase the photosynthesis by promoting the nutrient element uptake, and this would increase growth and yield of the plant

Summary

Introduction

Cucumber is one of the main vegetables in Iran that is predominantly cultivated in plastic greenhouses it constitutes the fourth most important vegetable crop after tomatoes, cabbage, and onion in Asia (Eifediyi and Remison, 2010). The fertilizers have an important role in increasing food production, and the foliar application of micronutrients has a positive effect in increasing fruit yield and quality. Researchers have indicated that foliar spraying of macro and micronutrients have been used as a means to improve the yield and quality of fruits (Kumar et al, 2014). The fertilizers derived from nanotechnology in agriculture have garnered excessive attention and have a fast-growing field. The use of nano-fertilizers leads to increased efficiency of the elements and improved growth, with improved fruit set and yield. This potential contribution of nano-fertilizers in improving growth and yield is derived from greater absorbance and high reactivity
