Effect of Varieties sowing dates and density on the green pods yield of pea in Hama

The research was conducted during the growing season in 2013- 2014 in Bssiren Hama. In a split- plot design: the varieties were main plots (asgro, rama, Muncipal) and the sowing dates were subplots (15\11;30\11;15\12 and 30\12) and the densities were subplots (20 plant\m2, 13.33 plant\m2). The early planting went to Significant increase in the days to germination, long time of fruit; the number of days to flowering and the number of days to fruiting; Plant height; Number of branches plant ; weight of pod; number of pods plant; dressing percentage; Yield of green pods plant and Yield of green pods. While the high density was observed Significant increase in the Plant height; Number of branches plant; weight of pod; number of pods plant; and Yield of green pods plant, while the low density was observed Significant increase in the Yield of green pods. The Asgro variety was obtained at Rama and Muncipal varieties in the number of branches plant; number of pods; Yield of green pods plant and, while the Rama variety was obtained by the plant height, and non- significant results were found among varieties by the weight of pod. The positive results also showed in the interaction among factors.

Effect of organic and potassium fertilization on some productivity characteristics of olive cultivars Sorani and Kaissy grown in Basaltic soil

This investigation was carried out on fifteen years old Sorani and Kaissy olive cultivars (Oleaeuropaea L.) trees grown in Basaltic soil that was poor in organic matter and potassium. The aim of the present investigation is to study the effect of different amount of organic and potassium fertilization on yield, fruit weight, oil percentage, and oil acidity. Results obtained showed that the highest value of fruit weight, yield, and oil precentage exhibited statistically the highest values by trees fertilized with the treatments (Organic + Potassium). Acidity increased in (Organic + Potassium) treatments but it was less than 2% oleic acid , while it was less than 1% oleic acid in Potassium treatments and in Organic treatments (Extra vergin oil).

Effect of Row Spacing and Number of Plants per Hole on the Yield and Yield Components for Some Peanut Cultivars under Local Conditions

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

Estimation of Heterosis of some productive traits for hybrids of maize(Zea mays) under industrial infection by large corn stem borer Sesamiacretica

This study was conducted at the of field research station Sianow belong to the General Commission for Scientific Agricultural Research at Lattakia, to evaluate the susceptibility of maize hybrids produced by using half Diallel the cross according to the design ofrandomized completeblocks (R.C.B.D), under industrial infection by large corn stem borer Sesamia cretica. Hybrids were compared with the control (Ghouta- 82). The hybrid (P1 × P2) Showed positive and highly significantheterosis for Ear diameter and tolerance forlarge corn stem borer compared with the average of the parents and the best parents and the check (Ghouta- 82). The hybrid (P2 × P6) showed positive and highly significant heterosis for the number of kernels per row compared with the average of the parents and the best parents and the check (Ghouta- 82). Also the hybrid (P1 × P6) showed positive and highly significant heterosis for the number of kernels per row relative to the average of the parents and the best parents and the check (Ghouta- 82). hybrid (P4 × P6) showed positive and highly significant heterosis for the recipe grain yield compared with the average of the parents and the best parents and the check (Ghouta- 82). The hybrid(P5 × P6) also showed positive and highly significant heterosis for the Percentage of dead hearts of the developing summit compared with the average of the parents and the best parents, and compared with the check (Ghouta- 82), therefore it can be considered as a sensitive hybrid.

Effect of Spraying By Organic Fertilizers and Growing Point Pinching On the Growth and Yield of Okra. (Abelmoschus esculentus Ls.)

An experiment was conducted in agricultural college arboretum that belong to tishreen university on okra during the growing season of 2013-2014 to investigate the effect of spraying by organic fertilizers and growing point pinching on the growth and yield. The experiment include 8 treatments as control (without spraying by organic fertilizers or growing point pinching), two kinds of organic fertilizers (ultra humic acid and amino vega) with or without growing point pinching. Plots were completely randomized over the experimental area having four replicates for each treatment. Each replicate contained 14 plants. Results showed that the highest values of vegetative growth parameters are stem length branch number ,leave number per plant due to the interaction between pinching of growing point and spraying by ultra humic acid and amino vega . The experiment results revealed also ,that the highest yield and The largest number and weight of fruits was produced from growing point pinching and spraying by ultra humic acid and amino vega, compared to all other treatments.
