A study was carried out at the Teaching and Research Farm of the Department of Crop Science, University of Nigeria, Nsukka to evaluate the growth and yield of four improved cassava varieties, determine their optimum NPK fertilizer rate and the best modes of fertilizer application for increased productivity. The experiment was factorial laid out in a randomized complete block design with three replications. Four varieties of cassava, four fertilizer rates and three modes of fertilizer application were used for the study. The early planting had higher survival count, number of leaves, tuber and garri yield when compared with late planting. The variety TMS 98 05 05 gave significantly (p< 0.05) higher number of leaves, tuber and garri yields of 39.8 and 9.68 t/ha, respectively, at 12 months. At 6 months of crop growth, 200 kg/ha fertilizer application rate gave significantly higher tuber and garri yield of 24.69 t/ha and 5.15 t/ha, respectively. Furthermore, 400 kg/ha of NPK fertilizer rate gave higher tuber and garri yields of 39.4 and 10.12 t/ha, respectively at 12 months of crop growth. Split application of fertilizer gave significantly higher tuber and garri yield from single application, though it is statistically similar to split-split application. Therefore, early planting, 400 kg/ha fertilizer rate and split application should be adopted for cassava production. The variety TMS 98 05 05 with higher growth and yield should also be adopted by farmers for cassava production in Nsukka derived savannah agro-ecology.

Inorganic fertilizer application and the quantity required by the crop for optimum production led agronomists to introduced varying measures in crop production. A study to investigate the effects of single and split NPK 15-15-15 fertilizer application on muskmelon (Cucumis melo L.) production was conducted at the Teaching and Research Farm of Ekiti State University. A 4 × 2 factorial experiment laid out in a Randomized Complete Block Design in three replicates with four varying rates (0, 167, 333 and 500 kg ha-1) of NPK 15-15-15 fertilizer applications and two-mode of applications (single and split) serves as the treatments. Data collected include the number of leaves and branches, vine length, number of fruits, fruit length and width, fruit weight, fruit flesh thickness (fruit pulp width), number of seeds fruit-1 and seed weight. Collected data were subjected to analysis of variance (ANOVA), and treatment means separated with Duncan Multiple Range Test at 5% level                            of probability. The split application at 333 kg ha-1 NPK fertilizer produced a significantly higher number of leaves (90), leaf area (109.58 cm2) and vine length (110.77 cm) at 10 WAS than other applied fertilizer rates. The split application of 500 kg ha-1 NPK fertilizer produced a higher fruit yield                    (12.64 t ha-1) than 12.09 t ha-1 from the single application which was not significantly different                  from the 333 kg ha-1 NPK fertilizer. The results indicated that the split application of NPK                 fertilizer is a better fertilizer application approach than a single application for muskmelon production.

A field trial was conducted at the experimental farm of the Department of Crop Protection and Environmental Biology, University of Ibadan, Nigeria, to determine the growth and yield response of cucumber (cv. Poinsett) to timing of fertilizer application. Fertilizer (20:10:10), at the rate of 150 kg N ha-1, was applied at: planting, 3 weeks after planting (WAP) and 6 WAP. Similarly, split applications were given at planting + 3 WAP, at planting + 6 WAP and at 3 WAP + 6 WAP. The experimental design was a randomized complete block with seven treatments (six fertilizer application treatments plus a non fertilizer control) and four replications. Means were separated using Duncan’s Multiple Range Test at the 5% level of significance. In general, plants that were fertilized performed better than control plants in terms of vegetative growth and yield. A split application at 3 WAP + 6 WAP performed the best in terms of vegetative growth and fruit yield. Fertilizer applied once-over at 6 WAP was the least beneficial; application of fertilizer once-over at planting, or a split application at planting + 3 WAP, resulted in a high level of vegetative growth but lower fruit yield compared with the split application at 3 WAP + 6 WAP.

Extending the planting area to a less-fertile soil, such as Ultisols, become inevitable choice to increase the national chili pepper production in Indonesia as this types of soil is the largest part of dry land of Indonesia, about 29.7% or around 51 million ha.  However, efforts to increase its productivity by providing sufficient fertilizers application is most frequently inefficient because in the conventional fertilizer applications, broadcasted fertilizer on the soil bed, are not readily available for the plant as their solubility is limited under the plastic mulch and still in the form of granular until the end of planting season.  Fertigation, therefore, maybe the answer for this problem.  The objective of this study was to determine the best NPK fertigation method on four chili pepper hybrids.  The experiment was conducted in a randomized complete block design with three replication, and the treatments were arranged in a split plot design.  As the main plots were NPK fertigation intensity, i.e. 100%, 75%, 50%, 25% and 0% fertigation with the remnant fertilizers were circularly broadcasted surrounding the plant.  As the subplots were chili pepper hybrids, i.e. ‘Maxima’, H39, H14, and ‘UNIB CHR17’.  The results showed that there was no interaction effect of fertigation intensity indicated that all hybrid genotypes showed similar pattern of responses.  The H39 hybrid had better vegetative growth compared to other hybrids in term of plant height, dichotomous height, stem diameter, number of branches, plant fresh-weight.  Whereas the hybrid cultivar ‘Maxima’ showed the highest yield followed by H14 and cultivar ‘UNIB CHR17’.  The 100% fertigation was the best method of NPK fertilizer application for chili pepper in Ultisols.keywowrd: fertigation, chili pepper, fertilizer application, acidic soil

<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>

Abstract Shallot production in Indonesia is still relatively low. This is due to the use of shallot bulbs that are not sterile and susceptible to disease. One way to increase the production of shallots is by using botanical seeds (True Shallot Seed). The research aimed to evaluate the growth and yield of two varieties of TSS with the application of NPK and Magnesium fertilizers. The treatment was arranged in a randomized block design with three factors. The first factor was varieties, which consisted of Sanren F1 and Lokananta varieties. The second factor was the application of magnesium, which consisted of without magnesium, 125, and 250 kg Mg ha−1. The third factor was the application of NPK, which consisted without NPK, 83.3, 166.6, and 250 kg NPK ha−1. The results showed that the effect of varieties, NPK fertilizer, and Mg were significant differences in the parameters of the number of leaves 7.0, and the number of bulbs plants 2.7 where sanren showed better results. While the effect of varieties, NPK, and Mg fertilizers was significant differences in the parameters of plant height 41.5 cm, the Lokananta varieties showed better yields.
