Read More Abstract Background and Objectives Biofertilizers are now one of the most important inputs to increase agricultural production. The use of biofertilizers in potato production could reduce the use of nitrogen fertilizers. On the other hand, previous studies have shown that the spraying of amino acids not only improves the growth and yield of plants, but also improves the activity of useful microorganisms. Materials and Methods The aim of this study was to investigate the effect of application of biofertilizers (non-application of fertilizers, application of pseudomonas, application of azotobacter, and application of azospirilium) and spraying of amino acids (non-spraying of amino acids, spraying with 2.5, and 3.75 g /L) on growth, yield, and nutrient uptake of potatoes. The study was carried out in Malek Azad University as a split plot based on the randomized complet block design with three replications in 2018. The studied traits in this study included the number of tubers per plant, length of tuber, number of tubers per plant, mean weight of tuber, tuber yield per m2, nitrogen percentage, phosphorus percentage, and tuber protein percentage. Results Based on the results of this study, all traits except the percentage of phosphorus, the interaction of two factors such as biofertilizer, and the spraying of amino acids did not have a significant effect, but each of the studied factors had a significant effect on the growth and yield of potatoes. The yield of potato plants affected by spraying with a concentration of 3.75 g / l of water increased by 44.6% due to an increase in the average weight of the tubers (7.7%) and the number of produced tubers (32.2%) was in the bush. The application of biofertilizer increased the yield of both functional components, the average weight of the tuber and the number of tubers on potato tuber yields. Azotobacter application treatments and Azosperilium application increased the potato tuber yield by 29.6 and 34.1%, respectively. Potato leaf area was not affected by amino acid spraying, but the biofertilizer had a positive effect on this trait. The percentage of protein in potato tubers also increased by the influence of amino acid spraying and the application of bio-fertilizer. Discussion Both spraying agents of amino acids and biofertilizer had a positive effect on the dry weight of potato leaves. Improving the assemilation of carbon dioxide in leaves due to the use of amino acids and biofertilizers was probably due to increased potato growth and yield. The results of this study showed that soluble treatments with a concentration of 3.75 g / L of water, application of Azotobacter and application of Azospirilium could have an effective role in increasing potato yield.

Read More Abstract Background and Objectives Sprouting is one of the main reasons of wasting about one half of potatoes during the storage. The existing methods to control sprouting in long term storage (for example postharvest applications of chlorpropham) can do the job as well, but the incidence of quality problems and undesirable side effects in such potatoes, and more importantly, the growing interest in organic food products, have challenged the application of these methods. Materials and Methods The peppermint extracts used in the experiment were obtained from dried peppermint leaves in 48 hours, at room temperature using 1:1 distilled water-alcohol solution, and with the normal air pressure. The peppermint extracts were dried for 10 days and then transferred to a dark glass bottle by means of petroleum ether (as solvent) and were kept at 2°C until being used for later use. Herbal extracts of peppermint were used at concentrations of 0, 0.5, 1, 2 and 4 g/l, with regular intervals of 2, 4 or 6 weeks during the 5 months of potato (Agria cultivar) storage while sprouting was monitored. Direct contact between tubers and the peppermint extracts was not allowed. To provide the needed oxygen for the tubers respiration, the containers apertures were opened for 15-20 minutes every four weeks and were sealed again. A group of tubers was only treated by 37g chlorpropham (5% purity). To do this, the powder was poured into the container, completely sealed and slowly shaken for 10 minutes. The sealed container was kept at room temperature for 48 hours. All experiments were repeated 3 times. Data was analyzed by a completely randomized design (CRD) with a factorial experiment. Results According to the results, by increasing the concentration of mint from 0.5 to 2 g/l, sprouting potato was controlled more effectively and meaningfully. More concentration in the control of potato sprouting was not significant. Use of this extract at a concentration of 0.5 g/l stimulates the germination of tubers compared to the control. Extensive sprouting of tubers was delayed for up to 4 months compared to the control treatment too. Application of peppermint extract caused %92 and %96 decrease in potato germination and total weight sprouting respectively. Organoleptic evaluation of the boiled and fried potato samples, treated with the mint extract and chlorpropham, did not show significant differences. Discussion Use of 2 g/l mint extract will be able to decrease waste potato tubers in storage up to 6 percent. Replication of every 4 weeks extracts application is absolutely essential for the best result. Organoleptic evaluation of the boiled and fried potato samples, treated with the mint extract and chlorpropham, received more points compared to control.
