Abstract

The present study deals with the effect of 1.0 Hz electric pulses on potato plant (Solanum tuberosum L.) in both Lab and Field Condition. A recently discovered technique proven to be effective against bacterial brown rot.
the Lab Experiment were done using Seed tubers variety (Spunta) and under normal environmental conditions in day light in plastic bags which were divided into two groups one is clay and the other in sand soil and each group divided into 3 groups for exposure the first did not receive any exposed (control). The second were exposed to electric impulses at day 35 post implantation for a period of one hour. The third group received further exposure to the electric impulses at day 70 post implantation for a period of one hour.
The Second Experiment were conducted in growing season (2017/2018), at a farm in El Monufia Governorate as a field model using two Seed tuber cultivars (Spunta and Almond) in clay soil Land. Half of the fields were planted with variety Spunta and the other half were planted with variety Almond. The land was equally divided into three subgroups the first were used as control which did not receive any treatment. the second exposed to electric field (EF) at day 35 post implantation for a period of one hour. The third exposure done at day 70 post implantation for a period of one hour.
The electric field used in the experiment is the lowest of the non-ionizing radiation with the lower energy possible, Lower than visible light, infrared, and radio waves, and mechanical waves such as ultrasound. The common sources of such waves include the sun, electrical appliances, mobile phones, and Wi-Fi.
The used EF in the experiment is of extremely low energy with almost no heat effect and far below the permissible range of residential exposures, Safety limits of exposure guidelines and limits where considered.
Plant growth parameters were recorded namely Leaf number, shoot and root length and Weight, number of tubers per Plant, Potato tuber weight, Leaf area, total chlorophyll, total proteins and Elements were determined for both experiments but amino acids, ascorbic acid and anti-oxidant enzymes for lab experiment only.
In the first experiment potato plants exposed to the EF treatment showed increase in shoot, root and tuber dry weight with increase of N, P, K+ and Ca2+ content along with total chlorophyll, carbohydrates, proteins, amino acids, ascorbic acid and anti-oxidant enzymes specially for the second treatment . but with almost no change to the number of tubers per plant.
In the second experiment Improvement of plants parameters in the field. The exposure effected the tubers as a result of source-sink relationship between Plant photosynthetic organs and storage organs. EF Effects Leaves area which showed significant increase with shoot and root weight increase then extended to tubers chemical content. tubers obtained from treated plants recorded high elements content, vitamin C, Carbohydrate and Protein content which contribute to a healthy and higher quality potato crop.
Recommendation
The improvement of the vegetative growth and tuber quality Revealing the advantages of the technique which could help prevent environmental pollution by reducing the use of chemicals that would be environmentally harmful for humans and biodiversity. Also, the need of further investigation to understand the mechanism and the potential of using such a promising technique as a sustainable agriculture method.
