A pot experiment was conducted during a two-year period in order to evaluate and compare the salinity tolerance of 10 Iranian commercial cultivars of pomegranate. Pots were arranged in a split plot design with two factors included water salinity as main plot in 3 levels of 4, 7 and 10 dS/m and 10 pomegranate cultivars as sub-plot and 3 replications. The properties concerned during the experiment were vegetative growth, percentage of alive cuttings after 2 month and the necrosis and chlorosis of leaves. In the end of the experiment the vegetative yield and root dry weight were also measured. In addition, irrigation water, drainage water, soil in plots, root, stem and leaves were analyzed for elements such as Na<SUP>+</SUP> and Cl<SUP>–</SUP>. The obtained results indicated that the best vegetative growth conditions were related to Voshike -e- Saravan and Tab -o- Larz cultivars at 4 and 7 dS/m salinity levels, respectively. Moreover, the most significant percentage of alive cuttings was related to Voshike -e- Saravan cultivar at each of the three studied salinity levels. Similarly, this cultivar had the minimum values of leaves necrosis and chlorosis at all three levels of salinity. Furthermore, the highest level of fresh yield was related to Zagh cultivar at 4 dS/m salinity level. The highest values of total Na<SUP>+</SUP> and Cl<SUP>–</SUP> were observed in shoots and leaves of Zagh and Voshike -e- Saravan cultivars at 10 dS/m salinity level as well. In general, Voshike -e- Saravan is the most salinity-resistant cultivar among 10 studied cultivars. Besides, Malas -e- yazdi and Tab -o- larz can be planted as salinity resistant cultivars in the second hand. Other cultivar cuttings were not resistant in salinity and finally died (even after the second year) and three cultivars of Gabri, Malas -e- Esfahani and Khafri -e- Jahrom were the most sensitive cultivars with the lowest salinity resistance.

Dioscorea is potentially used as staple food to support food security. The research was aimed to determine the effect of stake length and time of  stem twining  on  the growth of Dioscorea sansibarensis Pax. The experiment was conducted  in  Purwodadi Botanic Garden from December 2014 until May 2015 using split plot randomized block design consisted of two factors, i.e. the stake length and time of stem twining. The stake length was the main plot consisted of 150 cm, 100 cm and 50 cm above soil surface and without stake (control). The time of stem twining as subplots, i.e. stem twined early, twined at the time of 4 leaves stage, and twined at 8 leaves stage. Each combination of the treatments was replicated three times. The results showed that there was significant effect on the stake length  and the time of stem twining treatments on the plant growth and yield. The stake  length of 150 cm treatment produced the highest fresh tuber and total plant dry weight, i.e., 257.24 g and 132.77 g per plant, respectively. On the contrary, the plant without stake produced the lowest fresh tuber and  total dry weight of plant, i.e., 112.10 g and 48.65 g per plant, respectively.<br /><br />Keywords: biomass,leaf area, photosyntesis, tuber weight

Nitrogen was a key component for increasing yield and quality of vegetables like shallots. The growth and development of plants were influenced by nitrogen form. Common plants preferred nitrate for growth, but the enormity preference varies within plant species and other environmental factors. The purpose of this experiment was to study the effect of ammonium:nitrate ratio in sandy soil to growth and yield of shallot (Allium cepa L. Aggregatum group). The experiment had been conducted in August-October 2015 in the sandy land on Samas Beach, Bantul, Yogyakarta, Indonesia. The research was arranged in a Split-Plot design. The main plot was the source of nitrogen (NH4+; NO3-; NH4+: NO3- 1:1; NH4+: NO3- 1:2; and NH4+: NO3- 2:1) and the subplot was cultivars (Crok Kuning, Tiron, and Bima Brebes). Each subplot covered an area of 2.5 m² (2.5 m x 1 m) with three blocks as replications. Shallot bulbs were planted in sixth-row, spacing 20 cm between rows and 15 cm within rows. The dose was applied according to the recommendation of BPTP (urea 200 kg ha-1, ZA 250 kg ha-1, SP-36 150 kg ha-1, and KCl 150 kg ha-1) 144.5 kg N ha-1. Ammonium:nitrate ratio influenced shallot growth in sandy soil through number of leaves at maximum vegetative phase and its leaf area. The NH4+: NO3- 1:2 ratio gave the best result in dry weight of leaves following bulb dry weight than other ratio. Nevertheless, ammonium:nitrate ratio had no significant influence on bulb dry weight (ton ha-1).
