Influence of rooting media and number of nodes per stem cutting on nursery performance of vanilla (Vanilla planifolia Andr. syn. Vanilla fragrans)
The effect of rooting media and number of nodes per cutting on nursery performance of vanilla fragrance were evaluated in South-western Ethiopia in 2011/ 2012. Six rooting media (forest soil, decomposed animal manure, fine sand, 1:1 mixture of forest soil: fine sand, 1:1 mixture of decomposed animal manure: fine sand and 1:1:1 mixture of forest soil: decomposed animal manure: fine sand) and four levels of node number...
The effect of plant growth regulators and their concentration in vitro on mass poropagation of Myrobalan 29C rootstock
Myrobalan 29C is one of the most important rootstocks that is widely used for plum and apricot trees. This study was conducted to determine the most suitable media culture and regulators of plant growth for micropropagation of Myrobalan 29C in Khorasan Natural Resource and Agricultural Research Centre Mashhad, Iran. 10 explants treated were sterilized in 70% Ethanol for 1 min, Mercuric chloride (0.1%) for 1, 2 and 3 min...
Lettuce growth characteristics as affected by fertilizers, liming, and a soil conditioner
The aim of this work was to test fertilizers, liming, and levels of a soil conditioner produced from leonardite, composed by humic and fulvic acids on “iceberg” lettuce growth characteristics. The experimental design was completely randomized in a 5×3×2 factorial scheme, with 5 levels of soil conditioner (0, 20, 40, 100 and 200 L ha-1), 3 fertilizers [chicken manure, plant compost (plant residues...
Tolerance of bio-fertilized Delonix regia seedlings to irrigation intervals
This work aims to investigate the effect of different bio-fertilizers (Arbascular mycorrhizae fungi, Azotobacter chroorcoccum, yeast strains and mixture of all inoculum) and irrigation intervals (3, 6 or 12 days) on the growth and chemical composition of Delonix regia seedlings grown in sandy soil. Pot experiments were conducted using a randomized complete blocks design with three replicates during two successive...
