Aims: An experiment was conducted to compare the growth performance of two varieties of Moringa oleifera (wild variety and PKM-1) under different seasonal period at two locations in northern Burkina Faso, and the potential for improving household nutrition. Study Design, Place and Duration of Study: Two separate trials corresponding to sowing period (cold and warm) were laid out at each site (Bani and Tougou) in a completely randomized block design with three replicates between December 2017 and September 2018. Methodology: Each block was subdivided into two plots of 8 m² (separated from each other by 3 m break) intended to receive each variety of Moringa at each sowing period. The seeds were sown with 2 seeds by pit at 2 cm depth with spacing of 0.5 m x 0.5 m in each plot ploughed up to 30 cm. Watering was done daily during the dry season and consisted of applying 24 liters of water in each plot at two times. Vegetative growth measurements (plant height, number of leaves) were done weekly while leaf biomass production was assessed monthly from the 40th day after sowing. Results: The results showed that seedlings growth parameters and foliar biomass differed significantly (p < 0.001) among the two Moringa oleifera varieties and were influenced by the sowing period and sites. Although the two varieties grew well, Moringa oleifera var PKM-1 grew faster and produced much leaves compared to the wild or local variety. Then, greater growth attributes (height and number of leaves) and foliar biomass were noted for PKM-1. Conclusion: The warm period (March / April) appear to be the most recommendable period for the growth and biomass accumulation of the two varieties of Moringa oleifera.

A pot experiment was carried out to evaluate the influence of various organic manures on the growth performance and biomass production of Bryophyllum pinnatum. Nine kinds of organic manures, such as ACI, BGF-1, bone meal, Green life, Kazi, Majim, mustard cake, Payel and Shebok composts were applied individually at the rate of 15 ton/ha. Highest height (45.25 cm), leaf number (102.67 no./plant), leaf area (82.43 cm2/plant), number of branches (27.00 no./plant), girth (6.75 cm/plant), total fresh weight (334.02 g/plant) and total dry weight (86.09 g/plant) were recorded in mustard cake compost treatment at harvest. Results showed that the best growth performance and biomass production both were achieved by mustard cake compost treatment. Dhaka Univ. J. Biol. Sci. 29(2): 229-236, 2020 (July)

This work is part of a megaproject that seeks to isolate microalgae of the Chlorophyta division native to Norte de Santander and identify their potential applications such as lipid production to be used as biofuel. Here we present the isolation of 11 microalgae strains from the Chlorophyta division found in two different wastewater environments. The collected strains were cultivated in selective media and purified through serial dilutions, depletion culture, and application of penicillin and gentamicin. Biomass production was evaluated and two strains were selected: CHL1 (Chlorella sp.) and DES1 (Desmodesmus sp.). The strains were cultivated on wastewater and PCG media (control), and their biomass concentration and lipid content were measured. Both strains reached similar biomass concentrations compared to their respective controls (CHL1 PCG 1.5 mg/L ± 0.035 mg/L, CHL1 AR 1.68 mg/L ± 0.036, DES1 PCG 1.66 mg/L ± 0.007, DES1 AR 2 mg/L ± 0.03) and their lipid content was slightly higher compared to their controls. The results show that the isolated and evaluated strains may have potential to be lipid producers, since their environmental and nutritional conditions have not been modified yet and adaptation may improve the production yield of lipids.

<p style="text-align: justify;"><strong>Background and aims</strong>: Many models have been developed to evaluate crop growth and development, but few are capable of simulating grapevine systems. The present study was carried out to evaluate the ability of the STICS model to represent grapevine phenology, biomass production, yield and soil water content in two situations differing with respect to rainfall distribution and water management strategies.</p><p style="text-align: justify;"><strong>Methods and results</strong>: Simulations were performed for an irrigated vineyard in Chile and an irrigated and a non-irrigated vineyard in France. The crop model gave a good estimation of the main stages of grapevine phenology (less than six days difference between simulated and observed values). Soil water content was the best simulated variable (R2 = 0.99), whereas grapevine evapotranspiration observed only in Chile (R2 = 0.43) and leaf area index observed only in France (R2= 0.80) were the worst simulated variables. Biomass production, yield and their components were correctly simulated (within the 95 % Student confidence interval around the mean observed value). A comparison of the fraction of transpirable soil water and vine water potential measurements with the water stress indices calculated by the STICS model showed that the time and duration of the grapevine water stress period was correctly estimated.</p><p style="text-align: justify;"><strong>Conclusions</strong>: Therefore, the STICS model was reasonably successful in simulating vine growth and development, and identifying critical periods concerning the vine water status.</p><p style="text-align: justify;"><strong>Significance of the study</strong>: The STICS model can be used to evaluate various water management strategies and their impacts on grape production.</p>

Formulated Feed

The study was conducted to assess the effect of formulated feed on the growth performance of prawn both in aquarium and pond system during 25 September to 25 December 2013. The feeds/diets were, diet 1 (formulated feed), diet 2 (commercial feed), diet 3 (custard cake) and diet 4 (shuji-ata ball). Protein percent of the feeds were 34.51% in Diet-1, 32.67% in Diet-2, 25.41% in Diet-3 and 21.43% in Diet 4. Four experimental diets were assigned to four treatments viz. T1, T2, T3 and T4 both in aquarium and pond. The water quality parameters were monitored 15 days interval and the ranges were: temperature 26°C to 29.8°C (aquarium system) and 24.5°C to 29.9°C (pond system) ; pH 7.07 to 8.09 (aquarium system) and 7.87 to 8.45 (pond system); DO 7.07 to 8.09 (aquarium system) and 5.08 to 5.86 mg/L (pond system). The result of the present study showed that Prawn feed Diet 1 and Diet 2 resulted highest weight gain 2.42 and 2.39 g (aquarium system) and 3.63 and 3.5g (pond system), respectively. Based on the result of present study, it could be suggested that shrimp waste can be replaced in the diets of prawn (Macrobrachium rosenbergii) along with other ingredients. J. Environ.
