Abstract :
Potato (Solanum tuberosum L.) is one of the staple foods for humans, with a very high yield. This experiment was conducted in 2014 at the Agricultural Research Station of Ferdowsi University of Mashhad with a geographical position of 59 degrees and 28 minutes east, latitude 36 degrees and 15 minutes north and an altitude of 985 meters above sea level on a factorial potato plant. In the framework of the basic design, randomized complete blocks with 9 treatments and 3 replications were performed. Experimental factors included nitrogen at 3 levels (0, 100, 200 kg / ha) and fungal compost at 3 levels (0, 15, 30 t / ha). Traits such as leaf area index, shoot dry weight, mean tuber weight , Number of tubers, total gland function were examined. The results showed that all measured traits except total yield were affected by fungal compost residue and also except for the number of tubers, other cases were affected by nitrogen. The effect of combining fungal compost waste and nitrogen also had a significant effect on all parameters. The highest leaf area index (2.52) and total yield (28 tons per hectare) from the combined application of 100 kg of nitrogen with 15 tons of mushroom compost waste were obtained per hectare. Based on the results, the application of nitrogen fertilizer and fungal compost and their interaction had a very important effect on the yield and yield components of the tuber. Our results show that fungal compost waste, with proper nutrient management, can be used to benefit crop production.
