Oil quality and quantity of three olive cultivars as influenced by harvesting date in the middle and southern parts of Jordan. ABSTRACT Olive fruits of three promising Jordan cultivars (Nabali, Improved Nabali and Abo-shoka) were harvested at different harvesting dates at...

The objective of this study was to determine if the application of two antitranspirant compounds would moderate water deficit stress effects on physiological responses of “Granny Smith”, “Royal Gala” and “Golden Delicious” apple (Malus domestica Borkh.) trees on MM106 rootstock that occur during deficit irrigation. Uniform trees were grown in pots...

Salt stress conditions have been found to destroy the vital physiological process in plant where slower cell division and cell enlargement or both and limit mineral nutrient uptake with clearly nutritional imbalance. A greenhouse pot experiment was carried out at Agricultural Research Station, Mu'tah University, Jordan to evaluate growth responses...

This study was conducted to determine the influence of irrigation regimes on yield of two tomato cultivars – TY-DANA and GS12. Experimental treatments were three irrigation intervals (2, 4, and 6 days), and three irrigation quantities (50%, 75%, and 100% of pan evaporation [Ep]). The total yield increased with increasing amount of irrigation water...

Seeds of the mahaleb cherry, Prunus mahaleb L., used as a rootstock in cherry production, germinate and emerge poorly due to seed dormancy. A greenhouse experiment was done to determine the effects of several treatments to overcome this dormancy, i.e. prolonged (30, 60 and 90 days) stratification followed by hot water treatment at 90°C (for 0, 10,...

The effect of beta-pinene polymer based Vapor Guard surround-type film antitranspirants on plant gas exchange (stomatal behavior, carbon assimilation and transpiration) and biochemical parameters (chloro-phyll and proline) of orange (Citrus sinensis L.) cultivars, namely 'Washington Navel', 'Red Blood' and 'Shamouti', under progressive water defici...

The suitability of treated industrial wastewater for irrigation of ‘Improved Nabali’, ‘Nabali’, and ‘Manzanillo’ olives was investigated. Irrigation with six electrical conductivity (EC = 0.78, 1.0, 2.0, 3.0, 4.0 and 5.0 dS m-1, respectively T0, T1, T2, T3, T4, T5) were compared in the greenhouse experiment. The olive trees in the field experiment...

The response of 'Nabali' olive plants to salt stress relief or exogenous salicylic acid (SA) pre-treat-ment under short-term salinity to improve salt tolerance was investigated. Transplants of 'Nabali' olive grown in plastic pots in sandy loam soils and irrigated with a nutrient solution supplemented with multicomponent electrolyte solutions were u...

Olive fruits of three promising Jordan cultivars (Nabali, Improved Nabali and Abo-shoka) were harvested at different harvesting dates at two locations in order to investigate the influence of cultivar and harvesting date on oil quality. The olive fruits were harvested manually at 15 day intervals throughout the experiment period, starting in Octobe...

A pot experiment was carried out to determine the changes in gas exchange, growth and chlorophyll contents of 'Washington Navel', 'Red Blood' and 'Shamouti' oranges (Citrus sinensis [L.] Osbeck) treated with 0.1 and 1 mM abscisic acid (ABA) under water deficit conditions in a partially controlled greenhouse for 150 days. The drought treatments were...

The reuse of saline treated industrial wastewater generated by textile firms mixed with municipal domestic effluent for irrigation was used to asses its effect on the mineral content of three olive (Olea europaea L.) cultivars under greenhouse and field conditions during two complete vegetative cycles. Chemical analysis of the treated wastewater in...

The effect of five irrigation regimes (20%, 40%, 60%, 80%, and 100% of "Class A" pan evaporation rate) were studied under field conditions in the main fruit growth phase of two apples genotypes, 'Red Ace Gold-en Delicious' and 'Red Edna', grafted on MM106 rootstock. The crop was harvested on 15 September 2008 and fruit size and weight were determin...

Sci., 14: 564-575 The suitability of treated industrial effluent came from Al-Husseun Bin Abdullah II Industrial Estate (HUIE) wastewater Treatment Plant for irrigation of olive (Olea europaea L.) was in...

The response of Zini grapevine to chloride salinity of six electrolyte concentrations of the irrigation water was investigated on two years old transplants grown hydroponically for nine months. Irrigation water salinity was increased at 20 mol_c m^-3 increments to a maximum of 100 mol_c m^-3 at constant stoic...

An experiment was carried out to study the influence of five concentrations of Indole butyric acid (IBA) i.e., 0, 2000, 4000, 6000 and 8000 ppm and two dates of collecting cuttings (December, 2000 and April, 2001) on rooting percentage and average number of roots for two local olive cultivars (Nabali and Improved Nabali). It was obvious that the ro...

A pot experiment was conducted to investigate the response of 2 olive cultivars 'Nabali Muhassan' ( NM) and ' Frantoio' (F) to osmotic stress and specific chloride toxicity. The plants were irrigated with multicomponent electrolyte solution of increasing salinity and 2 ionic compositions. Irrigation water salinity was increased at 10 molc/m3 increm...
