(Oriental Scientific Publishing Company, 2016) S. A. S. Fard
To investigate the effect of biologic manures Super Nitro plus & Humic acid on quantitative & qualitative features of Solanum tuberosum var Mafrona , the test has been done as Factorial in the form of completely random block design with 3 replication in Dasht-e-Mir Farm sited 20 km far from Khodabandeh city with 36,03 longitude and 49,22 latitude during crop year 2014-15. Treatments include 3 levels of Humic acid 0, 2, 4 ( Liters per hectare) as foliar application after weeding bush & super Nitro plus in 3 levels 0, 2, 4 ( Liters per hectare) as tuber impregnating with manure solution has been done. Results have indicated that Humic acid effect on studied features has been significant in (P<0.01) level and the highest yield and percentage of tuber dry matter from 4 (L/ha) treatment has been obtained 31120(kg/ha) and 19.08(j), respectively. In investigating the interaction of Super Nitro plus and Humic acid in yield per unit area; 4 (L) biologic manure and 4 (L) Humic acid with 31740(kg/ha) value had the highest yield; also, the highest percentage of tuber dry matter has been obtained from 4 (L) Super Nitro plus treatment and 4 (L) Humic acid with 19.36 (j) value which is at the same statistical group with 2 (L) biologic manure and 4 (L) Humic acid with 19.13(j). Also, the highest percentage of Crude Protein (CP) has been obtained from 4 (L) Super Nitro plus treatment and 4 (L) Humic acid with 8.70 (j). the highest value of auxin hormone has been obtained from 2 (L) Humic acid treatment and 4 (L) biologic manure with 311.9 Micromole/g value.
