In order to investigate the effect of pruning and potassium nutrition on pumpkin grain yield and quality, a factorial experiment based on complete block design with four replications was carried out in nooshar village of ardabil province, Ardabil, Iran, in 2007. Experimental factors include potassium nutrition in three level (0, 75 and 150 kg/ha from potassium sulfate) and stem pruning (without...

Salinity is one of the most important limiting factors for growth and product of plants around the world. Identification of salt tolerant varieties and improvement of plants tolerance are the most effective way to increase its performance. Experiments were conducted in a hydroponic system in order to study the reaction of borage (Borago officinalis L.) to salinity in terms of developmental chan...

effects of different k/ca ratios on the growth, yield and physiological characteristics in galia (cucumis melo var. reticulatus l. naud. cv. galia) grown in hydroponics were evaluated. the experiment was arranged in a completely randomized design of three replicates. melon seeds were sown in a medium containing perlite and vermiculite (3:1 v:v) and then irrigated with water containing different...

African yam bean (Sphenostylis stenocarpa) is an underexploited legume with the potential of becoming an alternative food staple to alleviate the problem of food security. An assessment was carried out on the growth and yield of AYB affected by Telfairia mosaic virus (TeMV) Infection. Telfairia mosaic virus caused severe mosaic, leaf distortion and malformation on AYB. Analyses of results revea...

A pot experiment was conducted to evaluate the effect of synthetic wastewater containing various concentrations of cadmium and chromium on Eucalyptus camaldulensis. Six month-old seedlings of E. camaldulensis were treated with Cd (II) and Cr (VI) for 18 months. Treatments were; T0: (Tap water, control), T1: 0.05 +1.0 mg L, T2: 0.10+2.0 mg L, T3: 0.20+4.0 mg L and T4: 0.40+8.0 mg L of Cd and Cr ...

Frequency of irrigation to the crops is the key factor for proper growth and economic yield. Therefore, in the current study growth of broccoli plants was investigated under different irrigation levels in pot culture condition. Five levels of irrigation schedules were applied including I0 [Non-irrigation control], I1 [Irrigation up to 15 days after transplanting (DAT)], I2 [Irrigation up to 30 ...

in other to evaluation of morphological and phenological traits of 24 populations, from four species chamomile of the genus of anthemis, an experiment were carried out using randomized completely blocks design (rcbd) in three replications in alborz research station in karaj, iran during 2011-12. 13 traits including: length and width of canopy diameter, plant height, number of flower, shoot fres...

This study examined the lodging resistance of mulberry tree (Morus bombycis Koidz. cv Kenmochi) shoots treated or not treated with succinic acid 2,2-dimethylhydrazide (SADH). The lodging safety factor, an indicator of lodging resistance, was defined as the ratio of critical lodging load to the leaf fresh weight observed, provided that the distribution of the critical lodging load along the stem...
