Allelopathic management of Avena fatua L. (Wild Oat) pernicious weed growing in Triticum aestivum (Wheat) L. crop fields

Study investigated the effect of aerial shoot of Fagonia arabica aqueous extracts (ASFAAE) on germination and some growth parameters as well as seedling protein profile of Avena fatua and Triticum aestivum in pure and mixed cultures. Phytochemical screening of F. arabica exerted the highest value of about (41.6 and 47.5mg/g) related to fagonine and saponin respectively and the lowest value of about (9.8mg/g) related to flavonoids.

No bake, vegan, easy to develop, shelf stable and convenience food “Fruit bars” are an excellent vehicle to provide nutrients especially iron as well as energy to its consumers. Eight treatments of fruit bars fortified with alternative ratio of indigenous iron fortificants (spearmint and apricot kernel) were developed with incorporation of (dried apricot, quince fruit paste, barley flour, dried milk powder) along with placebo and synthetic iron fortified fruit bars. Product was analyzed for proximate composition and Fe, for shelf stability water activity and free fatty acids were done, while were finally statistically analyzed after organoleptic judgment.Apricot kernel and spearmint had Fe 29.62 ± 0.47 and 87.32 ± 0.71 mg/ 100 g. During the storage study of 60 days, the Fe followed a non-significantly decreasing trend in all treatments. Ash content (%) was maximum in T2 followed by T1. Continue reading

Diverse influential factors for the growth and juice sugar production of Arenga pinnata plantation

Diverse influential factors for the growth and juice sugar production of Arenga pinnata plantation

jbes

This paper reported the environment study that influenced the growth of the arenga pinnata plantation in Tapanuli Selatan Regency of Indonesia. Three reasons that made this research play an important; it revealed the factors that affect the growth of Arenga pinnata; gave the calculation of production of this plant; and contributed to farmers, local government, and researcher.  Its methodology applied two ways; one was an observation in the field work for the growth based on the altitude position of plantation sites; second included a chemical analysis and calculation of juice production of Arenga pinnata.

Data found showed that the plantation sites affect the production of Arenga pinnata juice and sugar. If the site was on the 0-400 m above the sea level it made the low growth and less juice production of Arenga pinnata. In contrast, the highest growth and best juice production were found in the plantation site above 800 m from the sea level.  Analysis reported that the higher the pH the production of juice and the higher amount of sugar produced and the decreasing of C-organic soil was decreased C or N ratio which was made N easy to decompose and was accelerated N usage. the range of K at the study sites is between 0.11-2.35 and it can be seen that the relationship between K and the production of juice and the amount of sugar produced generally has a positive relationship. It concluded that the influential factors for the growth and juice and sugar production of Arenga pinnata plantation included the position of sites, pH, c-organic soil, the elements of N and K of soil.

Effect of biochar on soil chemical properties and nutrient availability in sandstone and shale derived soils

Effect of biochar on soil chemical properties and nutrient availability in sandstone and shale derived soils

Key Words: Biochar, Wheat straw, Sugarcane bagasse, Soil properties, Nutrient availability

A field study was conducted at Pir Mehr Ali Shah Arid Agriculture University (Research Farm Koont Chakwal, Pakistan) to investigate the effect of two different types of biochar on soil chemical properties and nutrient availability during Kharif season 2013-14. Two types of biochar were used wheat straw biochar (@ 5 and 10 t ha-1 and sugarcane bagasse biochar @ 5 and 10 t ha-1. Both types of biochar had no significant (P<0.05) change on soil pH, while electrical conductivity (EC) and total organic carbon (TOC) differed significantly (P<0.05) at higher rates i.e. 10 t ha-1 on both types of biochar. Nitrate-nitrogen and extractable potassium (K) did not significantly increase but available phosphorus (P), extractable zinc (Zn), iron (Fe), copper (Cu), and manganese (Mn) showed positive significant change. Soil treated with sugarcane bagasse biochar at @ 10 t ha-1 had greater TOC, EC, available P, zinc, and copper.
