Height, weight of wood, vegetative growth rates in field and pot condition and a comparison of biomass of Jatropha curcas L. by using fertilizer and without fertilizer were studied. Results showed that although survival rate in pot condition was higher (58.06%) than that of field condition (49.14%), other biomass parameters were better in field condition. Average biomass of plants (dry weight) in pot condition was 62.09 g, and it was 209.28 g in field condition after one year. Associations among the parameters of biomass growth of the plant also studied here to show how the rate of change of length and diameter of stem, number of branches are interrelated in overall vegetative growth. Fertilizers used in the process of cultivation of J. curcas, better yield in terms of biomass production could be obtained than the condition where no fertilizer was used. Here on an average biomass of plants was 291.25 g without fertilizer and it was 683.75 g when fertilizers had been used. The extent of differences in all conditions are analyzed in the paper. Analysis and findings of this study might help to get information on better cultivation of J. curcas for mass production of this plant.

The objective of this study was to evaluate the production of jatropha (Jatropha curcas L.) submitted to fertilization with cow urine and cassava water. The experiment was conducted under field conditions in the municipality of Lagoa Seca, Paraíba State, Brazil. A 5 x 5 factorial scheme was used in a randomized complete block design with 25 treatments and 4 replicates, using different volumes of cow urine and cassava water. Irrigation was performed twice a week corresponding to 100% of ET0, where all plants received the same water blade. The syrup with 750 mL of cassava water and 750 mL of cow urine provided a greater number of fruits (33.00); however, the larger green mass of the fruits (224.59 g) was obtained when cow urine was added into 1,000 mL of cassava water. The dry weight of the fruits obtained the lowest value (48.92 g), when 250 mL of cow urine was used in the absence of cassava water. The cow urine and cassava water increase production and weight of the fruit of jatropha, which can be used as organic fertilizer for the crop.

In this study, laboratory-scale suspended and biofilm microalgal systems were constructed under outdoor climatic conditions in Northern Thailand to compare their performances on nutrient nitrogen (N) and phosphorus (P) removal and biomass production from anaerobically digested piggery wastewater. At a cultivation time of 14 days, the results showed that removal efficiencies of nitrogen and phosphorus from digested piggery wastewater in biofilm microalgal system were higher than suspended microalgal system. Biofilm system removed on average of 96 % of TKN-N and 92 % of PO43--P, whereas suspended system removed on average of 84 % of TKN-N and 87 % of PO43--P. Average biomass production achieved 1.17 g dry weight/day for suspended system, while a lower production of 0.78 g dry weight/day was found for biofilm system in which possibly due to a long harvesting frequency of every 2-weeks. Meanwhile, biofilm system has an advantage over suspended system with respect to simple biomass harvesting. This combination of findings demonstrates that biofilm microalgal system is more suitable for removing N and P from digested piggery wastewater than suspended microalgal system. Besides, biomass production in biofilm microalgal system could be further optimized by shorter harvesting frequency and partially harvesting of the biofilm biomass. This study indicates that microalgae offer the potential to recover valuable nutrient resources from piggery wastewater and use biomass for sustainable energy production or other high-value products, which will improve sustainability of agro-industrial wastewater management in the future.

[THE EFFECTIVENESS Jatropha curcas (L.) LEAF EXTRACTS IN INHIBIT ROOT-KNOT NEMATODE (Meloidogyne spp.) INJURIES ON TOMATO].  One of the main problems in tomato cultivation is the attack of root purse nematodes (Meloidogyne spp.). Some methods of controlling Meloidogyne spp. which can be done including using plants as vegetable nematicides. This study aims to get the concentration of Jatropha leaf extract which is effective in inhibiting the Meloidogyne spp attack on tomato plants. This study used 48 plants, 24 plants for observation 35 days after planting and 24 plants for observation until the age of 77 days after planting. This study used a Completely Randomized Design (CRD) with the treatment of Jatropha leaf extract concentrations (0%, 10%, 20%, 30%, 40%, 50%), and repeated four times. The results showed Jatropha curcas extract in inhibiting the attack of root purse nematodes (Meloidogyne spp.) can maintain plant height, fruit number, fruit weight, and plant stover wet weight 35 days after planting, but no significant effect on stover wet weight plants 77 days after planting and dry weight of plant stover 35 days after planting and 77 days after planting. The concentration of Jatropha leaf extract tends to increase the concentration, the smaller the rate of infection and the population of Meloidogyne spp on tomato plants. The concentration of Jatropha leaf extract 35% - 45% is the optimum concentration in inhibiting Meloidogyne spp. on tomato plants.
