Abstract
The paper studies the effect of growth stimulants on morphometric indicators of cucumber plant growth and development in the phase of intensive vegetation and transition to fruiting. The study was carried out at LLC Agricultural Enterprise “Teplitsy Belogorya” on the parthenocarpic hybrid of cucumber Tristan F1. Within the scientific and production experiment the grown cucumber plants on cotton-mineral cubes with drip watering were additionally vegetatively treated with a humic fertilizer solution and Azosol 36 microfertilizer. Phenological observations were carried out and morphometric parameters were determined: plant height, stem and leaf weight, leaf area, root system weight. Under the influence of treatments, the leaf area and weight of cucumber leaves increased by an average of 20 and 17%, respectively. It was established that vegetative treatment with the studied solutions allows partially controlling physiological processes and organogenesis of the greenhouse cucumber plant. The vegetative organs of the cucumber plant leaf, stem and root were found to exhibit different abilities to accumulate chemical elements within the two experiments. The series of element distribution in the natural substance of the plant vegetative organs are shown (in a decreasing amount, total nitrogen, phosphorus, potassium for a series: leaf – stem – root; calcium, magnesium, zinc, iron, manganese and copper for the series: root – leaf – stem). The use of the studied fertilizers increased the commercial quality of cucumber fruits. Button contained a higher amount of total sugar and vitamin C, were environmentally safe in terms of the content of nitrates and heavy metals (cadmium, lead, arsenic, mercury). The optimization of productivity and quality improvement of cucumber plants using biological humic fertilizer and chelate microfertilizer increased the average yield by 5.5% and the profitability of ecologically safe greenhouse vegetables by 3.3%.
Highlights
The increase in the profitability of vegetable production of protected ground is often caused by the increase in the volume of production, but not by the increase in production efficiency
It should be noted that the use of environmentally friendly growth stimulants as an alternative to synthetic ones increases the quality of the output of protected ground, and significantly improves the environmental situation of production itself, which corresponds to indicators and strategies for the sustainable development of the modern agricultural market
Mass seedlings of Tristan F-1 cucumber hybrid were obtained on the 4th day after planting
Summary
The increase in the profitability of vegetable production of protected ground is often caused by the increase in the volume of production, but not by the increase in production efficiency. The development of the plant is accelerated, resistance to adverse environmental factors is increased. This allows inducing the genetic potential of productivity of modern varieties of greenhouse crops [7,8]. A typical example of biogenic stimulants is humic substances Tests show that they reduce the energy consumption of the plant body to overcome the negative effect of xenobiotics and stimulate metabolism [9]. It should be noted that the use of environmentally friendly growth stimulants as an alternative to synthetic ones increases the quality of the output of protected ground, and significantly improves the environmental situation of production itself, which corresponds to indicators and strategies for the sustainable development of the modern agricultural market
