این مطالعه با هدف بررسی تأثیر کاربرد کودهای زیستی و محلول‌پاشی اسیدهای آمینه بر رشد، عملکرد و جذب برخی عناصر غذایی در گیاه سیب‌زمینی انجام شد. آزمایش در مزرعه تحقیقاتی دانشگاه آزاد اسلامی واحد ملکان به‌صورت کرت‌های خرد‌شده در قالب طرح بلوک‌های کامل تصادفی در سه تکرار ودر سال 1397 انجام شد. تیمار‌ها شامل محلول‌پاشی اسید‌های آمینه (عدم کاربرد، محلول‌پاشی با غلظت 5/2 و 75/3 گرم در لیتر آب) و باکتری‌های محرک رشد (عدم کاربرد، کاربرد سودوموناس، ازتوباکتر و آزوسپریلیوم) بود. بر اساس نتایج به‌دست‌آمده، درصد پروتئین غده تنها تحت تأثیر محلول‌پاشی اسیدهای آمینه با غلظت 75/3 گرم در لیتر آب افزایش یافت. تعداد غده در بوته، قطر غده، متوسط وزن غده، عملکرد غده و درصد نیتروژن غده سیب‌زمینی تحت تأثیر محلول‌پاشی اسیدهای آمینه با غلظت 5/2 و 75/3 گرم در لیتر آب افزایش معنی‌داری داشت. عملکرد غده در واکنش به محلول‌پاشی اسیدهای آمینه با غلظت 75/3 گرم در لیتر آب حدود 6/44 درصد افزایش یافت. در این مطالعه، کاربرد ازتوباکتر و کاربرد آزوسپریلیوم نیز اثر افزایشی معنی‌داری بر صفاتی نظیر تعداد غده در بوته، عملکرد غده و درصد پروتئین غده داشت. عملکرد غده تحت تأثیر کاربرد ازتوباکتر و آزوسپریلیوم به‌ترتیب به‌میزان 7/35 و 7/41 درصد افزایش یافت. نتایج نشان داد کاربرد ازتوباکتر، آزوسپیریلیوم و محلول‌پاشی با غلظت 75/3 گرم در لیتر آب می‌تواند نقش مؤثری در بهبود عملکرد سیب‌زمینی داشته باشد.

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.
