Influence of rooting media and indole-3-butyric acid (IBA) concentration on rooting and shoot formation of Warburgia ugandensis stem cuttings

This study investigated the influence of different rooting media and indolebutryic acid (IBA) hormone concentration on root and shoot development in stem cuttings ofWarburgia ugandensis. Stem cuttings were treated with three different levels (0.3, 0.6 and 0.8% w/w) of IBA concentration (including a control- no IBA hormone) and propagated in three rooting media (milled pine bark, top forest soil and sand) under...

Using sulfur oxidizing bacteria and P solubilizing for enhancing phosphorous availability to Raphanus sativus

The present research was conducted in the Research Field of Agricultural Research Center of Chahnimeh, Zabol, Iran. Data related to the combined effects of rock phosphate, P solubilizing bacteria, sulfur and sulfur oxidizing bacteria on Raphanus sativus growth is scanty. The experimental design was a completely randomized design with eight treatments in three replicates. Treatments including: (1) control, (2)...

Comparison of antioxidant enzyme activities in leaves stems and roots of Sorghum (Sorghum bicolor L.) exposed to Chromium (VI)

This study was conducted to determine the response between different organs to assess which one was more severely affected. Thus, we exposed sorghum (Sorghum bicolor L.) to five level 0, 30, 60, 100 and 130 mg/L concentration of chromium (Cr) VI during two weeks and measuring the activity of glutathione-s-transferase (GST), glutathione reductase (GR), glutathione peroxidase (GPX), catalase...

Effect of sheep grazing on forage yield, yield components and grain yield of local black barley, under rainfall conditions in Iraqi Kurdistan

In Iraqi Kurdistan, farmers usually graze young barley if it sown early in fall and then let the crops recover for grain production. Barley field that was established from the seeds of harvest lost from the previous season (2008 to 2009), due to poor adjustment of the combine harvester. The plant population density was 190/m² at 13-2-2010; this was close to the normal rate 200 /m². The...

Effect of calcium, magnesium, sodium and potassium on farm plantations of various agroeclogical zones of Punjab, Pakistan

The immense impact of trees in the development of a country cannot be denied and over-emphasized. Pakistan has a narrow forest resource base extending over only about 4.8% (4.59% excluding farmland plantations) of its area, which is insufficient to provide the material needs for the growing population, expanding and to retard and arrest the ongoing environmental and ecological degradation process. Based on...

Seedbed preparation influence on morphometric characteristics of perennial grasses of a semi-arid rangeland in Kenya

Semi-arid rangelands in Kenya are an important source of forage for both domestic and wild animals. However, indigenous perennial grasses notably Cenchrus ciliaris (African foxtail grass), Eragrostis superba (Maasai love grass) and Enteropogon macrostachyus(Bush rye grass) are disappearing at an alarming rate. Efforts to re-introduce them through restoration programs have often yielded little...

Evaluation of anthelmintic activity of the stem bark extract and chemical constituents of Bridelia ferruginae (Benth) Euphorbiaceae

Anthelmintic properties of the stem bark extract and compounds isolated from Bridelia ferruginae were investigated. In relation to the traditional use of B. ferruginae against gastro-intestinal infections, bioactivity-guided fractionations of the CHCl3- and CH2Cl2-soluble fractions of the 80% MeOH extract from the stem barks of B. ferruginae yielded two known triterpenoids:...

Soil physicochemical properties under Acacia senegal varieties in the dryland areas of Kenya

Acacia senegal is a multipurpose drought-tolerant tree or shrub legume and is commonly used in agroforestry systems in sub-Saharan Africa for gum arabic production and soil fertility improvement. Despite its wide distribution in Kenya, there has not been exhaustive evaluation on the effects of the extant varieties (kerensis, leiorhachis and senegal) on soil properties under their...
