An investigation to evaluate the effect of Oil Palm Bunch Ash on Meloidogyne incognita infections on soybean (Glycine max) was carried out at the Research and Teaching Farm of the Federal College of Agriculture Ishiagu, Ebonyi State, Nigeria, in 2012 and 2013 cropping seasons. The treatment was Oil Palm Bunch Ash at different levels, (control, 5tons/ha, 8tons/ha and 11tons/ha) and was fitted into a Randomized Complete Block Design (RCBD) with three replications. Data collected were averaged on plant height (cm), number of leaves, number of galled roots, and number of galls per root (gall index) and initial nematode population and final nematode population at harvest. The data were subjected to statistical analysis of variance. Results showed that Oil Palm Bunch as at 11tons/ha produced the greatest control for root-knot nematode by significantly (P0.05) reducing the number of galled root and galls per root at harvest (gall index). Results also revealed that nematode population was high in the control plots. The growth and yield parameters were significantly (P0.05) higher in the plots treated with 8tons/ha and 11tons/ha of Oil Palm Bunch Ash. It is therefore, recommended that oil palm bunch ash from 11tons/ha could be employed by farmers to suppress root-knot nematode in soybean field and increase soybean yield.

Aim: A study was conducted to evaluate supplementary effects of oil palm bunch ash (OPBA) and poultry manure (PM) on the growth and yield performance of mungbeans. Study Design:  The study used a 3 x 3 factorial experiment laid out in randomized complete block design with three replications. Place and Duration of Study: The experiment was carried out at the University of Calabar Teaching and Research farm, Calabar, Nigeria during the 2014 and 2015 cropping seasons respectively Methodology: Mung bean variety NM 92 was planted in a well prepared field to evaluate its response to PM and OPBA applications. The treatments included three levels of OPBA (0, 5 and 10 t ha-1) and three levels of PM (0, 5 and 10 t ha-1. PM was cured and applied two weeks before planting while the OPBA was applied at planting.  Plant growth data including plant height, number of leaves, number of branches and leaf area were measured at 2,4, 6 weeks after planting whereas the yield data including days to fifty percent  flowering, number of pods, pod length , pod  and seed yield were recorded Results: The highest agronomic parameters as well as yield attributing characters and yield were obtained when 10 t ha-1 OPBA or 10 t ha-1 of PM were applied. Each of the levels of applications significantly decreased the number of days to 50% flowering. The highest seed yields of 0.77 t ha-1 in 2014 and 0.82 t ha-1 in 2015 were obtained with the applications of 5 t ha-1 OPBA + 10 t ha-1 PM and 10 t ha-1 OPBA + 10 t ha-1 PM, respectively. Conclusion: The best agronomic, yield attributing characters and yield of mungbeans were obtained when 10 t ha-1 OPBA or 10 t ha-1 of PM were applied. Also the combined application of 5 t ha-1 OPBA + 10 t ha-1 PM or 10 t ha-1 OPBA + 10 t ha-1 PM gave significantly higher increment in yield. Hence, from our study, it was found that both organic matter sources may be used to obtain higher yields in mungbeans.

The evaluation of nematicidal activity of the non- fumigant nematicide (fluensulfone) was evaluated for the control of the root-knot nematode Meloidogyne incognita in bell pepper crop (Capsicum annuum L.) under field conditions. The experiment was set up under a randomized complete block design with four replications. Six treatments were assessed for control of M. incognita: four doses of fluensulfone, one of the nematicide oxamyl and a control without application of nematicides. Ten days before transplanting, nematicides were applied in a single application via irrigation systems. The lowest final population densities of M. incognita in bell pepper crop were recorded in plots treated with fluensulfone at the dose of 2.75 L.ha-1, with an average of 25 juveniles. The higher percentage of efficacy was obtained with the application of fluensulfone at a dose of 2.75 L.ha-1. Fluensulfone showed a more efficient nematicidal activity as compared with oxamyl, which is the most used nematicide in horticultural crops in Mexico. Our results indicated that fluensulfone can be used as an alternative nematicide for the control of M. incognita in horticultural crops.

Red rice was one species of rice in Indonesia that was superior in nutritional content and selling price compared to white rice but the productivity of red rice is still low. One of way to improved rice growth and productivity is fertilization red rice was one type of rice in Indonesia that contains high nutrition. This research aimed to observe the effects of  the combination of organic and inorganic fertilizers on the growth and yield of red rice (Oryza nivara L.). The research used a Randomized Completely Block Design (RCBD) with 7 treatments. Each treatment had 3 replications and each experiment unit consisted of 3 plants so that there were 63 plants. The best treatment was compost of oil palm empty fruit bunch (125 g) + N, P, and K fertilizer 50%. The highest production was on oil palm empty fruit bunch compost (125 g) + Fertilizer N, P and K 50%,  it was equivalent to 5.49 ton/ha. In the red rice crop farming system it can be recommended to provide a combination of oil palm empty fruit bunch (125 g) compost and 50% N, P and K fertilizer to increase yields in the cultivation of red rice.

Field experiments were conducted during the 2015 and 2016 cropping seasons at the Teaching and Research (T & R) Farm of the College of Agriculture, Kwara State University, Malete, to determine the effect of cropping patterns on weed infestation, growth and yield of a maize/soybean intercrop in the southern Guinea savanna of Nigeria. The experiments consisted of six treatments as follows: one row of maize alternated with one row of soybean (1:1), one row of maize alternated with two rows of soybean (1:2), two rows of maize alternated with one row of soybean (2:1), two rows of maize alternated with two rows of soybean (2:2), sole maize (1:0) and sole soybean (0:1). The treatments were laid out in a randomized complete block design with three replicates. Data collected were subjected to analysis of variance and means were separated by the least significant difference (LSD) at the 5% level of probability. Results showed that sole soybean consistently suppressed weeds and resulted in a higher yield. Similarly, the 2:1 ratio of maize to soybean did not only reduce weed density, it produced significantly higher yields of maize and lower yield of soybean, and had the higher land equivalent ratio and economic returns followed by sole maize.

Tomato (Solanum lycopersicum L.) is an important and widely grown vegetable crop all over the world. Although tomato is nutritionally and economically important, its production is constrained by biotic and abiotic constraints leading to poor marketable quantity and quality worldwide. Root-knot nematodes are one of the major pests affecting tomato production worldwide, especially, in the tropical and sub-tropical regions. Green house experiments were laid out in Complete Block Design (CBD) with a 3x7 factorial arrangement replicated three times carried out at the Department of Crop and Environmental Protection, University of Agriculture. The soil was sterilized before the experiment. Fresh leaves and seeds of Moringa oleifera, Ricinus communis  and Jatropha curcas were washed with tap water, 15 g  from each of leaves and seeds of the different botanicals was macerated separately in an electric blender at high speed for 4 minutes in 100 ml distilled water. The mixtures were passed through a Whatman filter paper number 1; the filtrates of the leaves/seeds were then collected. Three tomato varieties viz: Roma Vf, Rio Grande and UC82B were inoculated with approximately 5,000 freshly hatched second stage juvenile of Meloidogyne incognita, two weeks after transplanting.  Thirty percent aqueous extract each  of Castor, Moringa and Jatropha leaves and seeds was used, while double distilled water (0%) served as the control. Thirty ml of   each leaf and seed aqueous extract was applied, 48 hours after inoculation as soil drench. Application was done at 1 weeks intervals thereafter for a period of 16 weeks. Data collected include number of fruits per plant, root gall index, nematode reproductive factor, and final nematode population. The results showed that various Moringa oleifera, Ricinus communis  and Jatropha curcas leaves and seed extracts significantly (P<0.05) reduced root gall index, final population of M. incognita in the soil and nematode reproductive factor than the control. Application of the various treatments Moringa oleifera, Ricinus communis  and Jatropha curcas led to significant increase in mean number of fruits and mean fruit weight yield of all the three tomato varieties. Therefore, the application of leaf and seed aqueous extracts of Moringa, Jatropha and Castor will serve as good alternative for the management of root knot nematode Meloidogyne incognita.

Agricultural activities such as watering crops with nematode-infested water from wells and boreholes, and using infected plant debris as manure or mulch increase root-knot nematode infection. So, this study aims at assessing the influence of the inoculation method and inoculum level of Meloidogyne incognita on the development of root galls on okra plants. Two M. incognita inoculation methods (suspension of individuals and galled root explants) and six inoculum levels (0, 10, 100, 500, 1000 and 2000 second-stage larvae/plant) were studied. The gall index, total numbers and reproductive factor of M. incognita were used to assess the effect of treatments on root gall development. Unlike the reproductive factor, gall index and the total numbers of M. incognita increased with their inoculum level. The pathogenic activities of M. incognita were most significant when crop soils were infested with galled root explants. However, an inverse relationship was found between the inoculum levels of M. incognita and the okra plant’s development. It is reflected by negative correlation coefficients ranging from -0.90 to -0.62. It is therefore important to burn roots infected with root-knot nematodes left in fields so that they do not act as an inoculum for crops.

<p>Soils of the southern Guinea savanna zone of Nigeria are inherently infertile due to shortened fallow period and the continuous use of inorganic fertilizer which depletes the soil of micronutrients such as zinc over time. A field trial was carried out at the Teaching and Research Farm of the University of Ilorin, Nigeria during the 2016 and 2017 cropping seasons to evaluate the effect of zinc and NPK fertilizer on the growth, yield and zinc concentration of seeds of sesame. The experiment was laid out as a factorial fitted into a randomized complete block design (RCBD), replicated thrice. The treatment consisted of four levels of ZnSO<sub>4</sub> (0, 5, 10 and 15 kg ha<sup>-1</sup>) and four levels of NPK 15:15:15 (0, 100, 200 and 300 kg ha<sup>-1</sup>). Data collected were subjected to analysis of variance (ANOVA) and means were separated using new Duncan multiple range test at 5 % level of probability. Results obtained showed significant effects of Zn and NPK rates on plant height, number of leaves, yield per plot and yield per hectare. The application of 15 kg ha<sup>-1</sup> Zn and 300 kg ha<sup>-1</sup> (15:15:15) NPK resulted in high yield and high zinc content of seeds.</p>
