Abstract

Growing populations, food demand and climate change necessitates the improvement of agriculture in sustainable ways. Microbials provide for an efficient green solution, and a potential replacement for the overuse of chemical pesticides. They have long been researched for their various beneficial effects in crop protection such as improving plant growth, stress tolerance and abetting plant pathogens. Despite their several advantages, the large-scale implementation of microbials is still at its primitive stage. This review attempts to identify the challenges that are barring the improvement of the microbials industry. Both the research and industry sections are explored, to recognize key issues, chokeholds and identify areas of improvement. This review provides a current and updated perspective into the use of microbials in agriculture.

Abstract

An investigation was carried out in green gram CO8. The objective of the experiment was standardization of NaCl to study the effects of salinity during seed germination of green gram and to study the response of green gram treated with plant growth regulators to salinity. In laboratory study, the standardization of NaCl was done first by using 75mM, 100mM, 150mM and 200mM NaCl. Among the four concentrations, 50% germination was observed in 150mM NaCl and it was standardized for further experiment. The plant growth regulators used were T3: NAA 100ppm, T4: NAA 200ppm, T5: kinetin 50ppm, T6: kinetin 100ppm, T7: GAᴣ 100ppm, T8: GAᴣ 200ppm along with T1: Absolute control and T2: Control (150mM NaCl). The experimental results showed a decrease in seedling growth due to salinity but with the seed treatment with the above mentioned PGRs showed an increased stress tolerance index, chlorophyll content and relative water content. The seeds treated with GAᴣ 200ppm recorded the maximum stress tolerance index (STI) (83.09) as well as higher relative water content (88.44%). While the seeds treated with kinetin 100ppm recorded the maximum chlorophyll content (1.22 gm/g). The whole study revealed that, in laboratory condition, with the imposition of salinity stress by 150mM NaCl, the seed treatment with GAᴣ 200ppm responded better compared to other treatments.

Abstract

Ethylene is an invisible, colorless and odorless gas, which has no known dangerous effect in humans, on concentrations found within the storage chain and sale of fruits and vegetables. The ethylene molecule is relatively small and simple: it consists of two carbon atoms associated with four hydrogen atoms. The molecular weight of ethylene is 28.05 gmol-1 and fruits and vegetables produce different amounts of ethylene as they mature. Usually, ethylene cannot be detected by humans, although sometimes only people with well-developed olfactory ability can smell large amounts, but to this fact other volatile organic compounds of fruits and vegetables also contribute. Since its specific weight (1,178 kgm-3 to 15oC) is similar to that of air (1,225 kgm-3 to 15oC), ethylene freely diffuses to any other adjacent fruit or vegetables and to the spaces in which they are stored.

In addition to CO and O , ethylene is the most important gas to be monitored and controlled in the fruit and vegetable supply 2 2 chain. Less than one part per million (1 ppm) in volume of ethylene gas, is enough to trigger the maturation process of the climatic fruit (which can continue to mature, once collected). Ethylene is considered a plant hormone that controls a wide range of physiological processes. During storage, after harvesting fruits and vegetables, ethylene may induce effects including senescence, over-maturation, accelerated quality loss, increased susceptibility to fruit pathogens and affecting different physiological processes. In addition to the endogenous production of ethylene by plant tissues, there are also external sources such as contaminants and the own metabolism of plants and fungi.

Abstract

The study investigated morphological variations among samples of Macrobrachium vollenhovenii captured from Taylor Creek, Calabar Estuary and New Calabar River in the Niger Delta Region. A total of 76 individuals were caught using cone-shaped bamboo basket traps. The prawns were identified and 18 morphological characters were measured on each individual. All the data generated were analyzed using the PAST3 and JASP statistical software. The results of the study indicated that the morphometric measurements among the populations of M. vollenhovenii total length, rostrum length, third segment length, fifth segment length and abdominal length were significant different (p < .05) while telson length, telson width, caudal length, merus length and palm length were not different (p > 0.05). The coefficient of regression in the length-weight relationship were positively allometric (p < 0.05) for all populations with values of 3.5402, 4.6686 and 4.420. The condition factor varied from 0.668 to 2.729 averaging 1.498, 1.628 and 1.630 for New Calabar River, Calabar Estuary and Taylor Creek, respectively.

Abstract

The hybrids of Clarias gariepinus with Heterobranchus species are economically very important. The reciprocal interspecific progenies of Clarias gariepinus♀ x Heterobranchus bidorsalis♂ (Cgf x Hbm) and H. bidorsalis♀ x C. gariepinus♂ (Hbf x Cgm) were produced in the Fish Farm Demonstration Unit of the University of Port Harcourt. At Two weeks, mean weights were 7.0mg±0.0008 and 6.5mg±0.0006 for CGm x HBf and HBm x CGf, respectively with the corresponding total lengths of 1.01cm ±0.011 and 0.97cm±0.008. At the end of the experiment, mean weight of 10.77±1.65/11.04±1.79 and total length of 11.08±0.38/ 10.96±0.54 were observed for Cgm x Hbf/Hbm x Cgf, respectively. The total length was significantly different (P< 0.05) at the commencement of the experiment, which leveled off by the third week. All the parameters including the Head length, Head width, Dorsal fin length and adipose fin length did not differ significantly (p>0.05) for the reciprocal progenies. The condition factor was 1.27 for Cgm x Hbf and 1.28 for Cgf x Hbm.

Abstract

Flours are among the essential raw materials used in industries such as food, pharmaceutical and other industries for the production of different products. Scarcity and undesirable qualities of flours now lead to search for plant materials of improved qualities from which flours of high value can be isolated. Improved variety of sorghum and cassava from the Anambra State Agricultural Development Program (ADP) were employed in this research. The proximate and physicochemical analyses were done using standard methods. Results showed that the sorghum and cassava yielded 44.8% and 68.7% quantities of pale white and white colour respectively with neutral pH. Sorghum flours had 4.35±0.11%, 2.6±0.23%, 0.26±0.03%, 3.28±0.06%, 2.16±0.10% and 25.02±1.02% respectively for moisture, ash content, fat content, crude protein, crude fibre and carbohydrate content. Cassava flour gave 5.24±0.58% (moisture), 3.35±1.02% (ash), 0.18±0.45% (fat), 1.02±0.33% (crude protein), 3.14±2.02% (crude fibre) and 28.06±0.54% (carbohydrate). Sorghum flour isolated also had 240.6±1.3%, 123.1±0.8%, 800.5±2.0%, 3.5±3.1%, 22.5±0.5%, 67.0±0.7 and 0.78±0.2% for water absorption capacity, oil absorption capacity, swelling power, solubility index, amylose content, amylopectin content and bulk density respectively while cassava flour showed 260.4±2.0% (water absorption capacity), 128.0±1.1% (oil absorption capacity), 744.3±2.2% (swelling power), 4.3±2.0% (solubility index), 32.0±1.2% (amylose), 78.0±0.2% (amylopectin) and 0.89±0.1% (bulk density). The two isolated flours showed good pasting properties with peak viscosity and final viscosity of 2215±2RVU and 1126±2 RVU for sorghum flour and 3204±5 RVU and 1422±3 RVU for cassava flour. It is therefore deduced that flours isolated from the improved sorghum and cassava varieties will be suitable and cheap source of raw material for food, pharmaceutical and other industries due to their high qualities.
