Unfavorable environmental conditions cause tension in plants and impairment in the development and survival of plants. Water deficit is one of the most important environmental factors limiting the cultivation of almond under rain fed conditions of Guilan province. The foliar application of plants growth regulators, such as ascorbic acid and methanol due to physiological and morphological effects improve plant tolerance to unfavorable environmental conditions. The present factorial experiment was conducted in a randomized complete blocks design with three replications in two locations north of Iran (Astaneh Ashrafiyeh and Kiashahr) in 2015 cropping year. Two factors investigated including methanol foliar application at four levels of zero (control), 7, 14, and 21 volumetric percentage and four levels of ascorbic acid foliar application at zero (control), 250, 500, and 750 milligram per liter were considered. Foliar application spraying started during code stage 73 (pod growth) and it was repeated 15 days later. The results showed the simple effects of methanol and ascorbic acid foliar applications on measured pod yield, mature pod number per plant, shelling percentage, one-hundred seed weight, immature pod number per plant, plant height, seed protein and seed oil traits were positive and significant. The results of the experiment showed that foliar application of growth regulators increased peanut yield under rain fed conditions by improving the seed yield components. The maximum amount on pod yield, mature pod number per plant and shelling percentage traits were observed by two foliar application treatments of methanol (14 and 21 volumetric percentage) and two ascorbic acid treatments (500 and 750 milligram per liter). Therefore, it can be concluded that in the conditions of peanut rain fed cultivation, the use of methanol and ascorbic acid can improve grain yield and yield components. |
