Abstract:
This research aimed to study the effect of application mineral fertilizer (MF), liquid biogas digestate (BD), on some vegetative, productive and quality characteristics of peanuts. The experiment was carried out during (2020) at Zahed station for Water and Irrigation Research, which is located in Tartous Governorate – Syria. The experiment was designed in a Randomized Complete Blocks Design (RCBD), which were 5 treatments and each of them was by 3 replications. The treatments were distributed as follows: control treatment which it was not fertilizer (T0), one MF alone (T1; N 140 kg/h, P 174 kg / h, K 80 kg/h), and three organic BD treatments (6, 8, 10) L/m2; (T2, T3, T4). The results of the statistical analysis of the BD treatments showed the superiority of the third level (T4) treatment (10) L / m2 over the first and second level (T2) and (T3) treatments in plant height, leaf index area, dry weight and biological yield characteristics. While it was not found any statistically significant difference between the two treatments of BD from (T2) and (T3) levels, according to total number of pods and pod yield characteristics. As for the oil ratio, it was found that there were no significant differences between all BD treatments at all levels. The results showed that for MF and BD treatments, each one alone, MF and BD of level T4 (10) L/ m2 had the same effect on plant height, dry weight, total number of pods, biological and pod yield characteristic. As for oil ratio; it was noticed that both MF and BD had the similar effect. Also, the results of the experiment showed that both treatments MF and BD were superior to the control treatment with high significant.
