The research was carried out during 2015 and 2016 seasons at Arab El-Mulk village, Banias district, in Tartous Governorate, to study the effect of planting peanut seeds size (mixture, small, medium and large), and spraying plants with bread yeast (Saccaromyces serevisiae) concentration of (4%) in three treatments (control, once and twice), on biological yield (BY), Economic yield (EY) and some physiological indicators; yield index (YI), Harvest index (HI), crop index (CI) and seed index (SI). The experiment design was set as split plot in a randomized complete block with four replications. The seeds size considered the main factor, while spraying yeast allocated the sub plots. The results showed that seed size caused significant increases in all of the studied indicators. The large seeds gave better values of (BY) 210 g, (HI) 30.56%, (CI) 44.12%, (SI) 74.85 g, except (EY) compared with mix, small and med seeds. Also the results showed that there were no significant increase between mixture and medium seed size in (YE) and (HI), but there was a significant increase in (BY) and (SI), on the other hand the treatments; spray yeast for once and twice had significant increases compared to the control, and the twice yeast spraying gave better values (215.22 g ,63.98 g, 29.64%, 42.37 % and 73.45g ) of (BY , EY ,HI, CI and SI) respectively, compared to the control. The interaction between seeds size and bread yeast spraying caused a significant increase which achieved 15.78 % in (BY), 23.99 % in (EY), 9.74 in (HI), 13.68% in (CY) and 7.87g in (SI) compared to the interaction between untreated treatment and small seeds size.

A field experiment was conducted in Agriculture collage –Tishreen University for two years 2011&2012 to evaluate the effect of tillage depths and nitrogen fertilizer timing application on growth productivity indicators and seeds' chemical compositi on of peanut plant. The experiment was designed in split plots with three replicates. The main plots included shallow tillage (8-10) cm, medium tillage (18- 20) cm and deep tillage (28- 30) cm tillage depths D1, D2, D3 respectively. Timing application (split- plots) were: T1 all nitrogen fertilizer applied at planting ,T2 half nitrogen applied at planting and half at flowering ,T3 all nitrogen fertilizer applied at flowering .Deep tillage caused significant differences and increased leaf area index to (11.93,11.80) for the two seasons respectively . For dry weight/plant were (285.9, 266.6) g for two seasons respectively and seeds index arrived highest values (74.32, 74.53) g for two seasons respectively. Tillage depth increased protein and oil percentage in seeds, but the effect was insignificant. Timing of nitrogen fertilizer had significant effect on leaf area index. The best values were (11.80, 11.60) for two seasons respectively in the treatment T2, and dry weight/plant (283.0, 263.4) g/plant respectively. Significant effect was observed for seeds index. The highest values were (74.41, 74.21) g for two seasons respectively in the treatment T2, so that for protein percentage in seeds arrived highest values (24.35, 25.24) % respectively in the treatment T2. But the highest values of oil percentage were (47.10, 47.21) % for two seasons respectively in the treatmentT3. Interaction (D x T) had significant effect on leaf area index. The best values were (12.53, 12.07) for two season respectively at (D3 x T2) interaction treatments. This interaction had no significant effects on the rest of the indicators
This research was conducted during the growing season of 2015 at AL-Arema village of governorate Tartus, to study the effect of three spray bio-fertilizer times (1- flowering stage. 2- pods formation stage . 3- seeds formation stage), and four rat es of biofertilizer (zero, 2 cm3/liter ,4 cm3/liter,6 cm3/liter) in the growth and productivity of peanut crop. The experiment was designed by using Split-plot design three replications.
The research was conducted in Dabba site for Agricultural Scientific Research at Lattakia region in the growing season 2011 during the period from early June to mid-October. The experiment included four cultivars of peanut (ICGV 92022, C16 local 262, Souri, Al-Baladi), three row spacing (40, 60, 80 cm), and two levels of number of plants per hole-1 (one plant per hole-1, two plants per hole-1). The experiment was designed by using split-split plot design with three replications. The results of the study showed that Al-Baladi variety was superior to all other cultivars in weight pods/plant (108.8 g), weight seeds/plant (56.8 g), weight 1000 seed (914.7 g) with yield of seeds reaching (3529 kg/h). On the other hand, ICGV 92022 was superior in number of mature pods (29.22 mature pod), in number of seeds/plant (53.90 seed) and in yield (3058 kg/h). Regarding the effect of row spacing, the spacing 80 cm between rows had given the highest values significantly for yield attributes in comparison with row spacing 40 and 60 cm. Yet the highest yield per unit area obtained with row spacing was 40 cm. As about the effect of number of plants per hole-1, two plants hole-1caused significant decrease in yield attributes and significant increase in seed yield in comparison with one plant hole-1
The search was conducted in Dabba site for Agricultural Scientific Research at Lattakia region in the growing season 2011 to study some physiological and productive parameters for peanut cultivars under the row spacing effect and number of plants p er hill, the experiment was designed by using split-split plot design with three replications. The treatments of experiment included four cultivars of peanut (ICGV 92022, C16 local 262, Souri, Al-Baladi) and three row spacing (40, 60, 80 cm) and two levels of number of plants hill-1 (one plant hill-1, two plant hill-1).
This research was conducted during 2014 season at Miaar Shaker plains in Tartous region, to study the effect of applied drought stress for 24 days in 4 growth stages of peanut crop, i.e., 1. Brunching stage, 2. Flower initialing stage, 3. Pod form ation stage, 4. Seed formation stage, beside of control (full irrigation by 12 days intervals). And effect of these treatments on some growth attributes and yield to peanut genotype (Sahel).
