“…Besides, phosphorus stimulates cell division, elongation as well as flowering and fruit set. This finding was in conformity with the work of Khandaker et al, (2017) who reported that the highest number of branches (7) per plant recorded form the highest rate of NPK fertilizer rates. Depending on the cultivar used the environmental condition and soil factors the number of branches per plant completely different.…”

Yield and productivity of Okra (Abelmoschus esculentus L. (Moench)) in Ethiopia has been far below other developing country standards partly due to poor nutrient management practice. Thus, a field experiment was conducted at Pawe Agricultural Research Center during 2018 main growing season to determine the effects of Nitrogen (N) and Phosphorus (P) fertilizer rates on growth, yield, yield components of Okra under Pawe conditions, Northwestern Ethiopia. The treatments consisted of factorial combinations of four levels of Nitrogen (0, 50, 100 and 150 kg/ha) and four levels of Phosphorus (0, 37.5, 75 and 112.5 kg/ha) that were laid out in a Randomized complete Block Design with three replications. Results of this study revealed that N and P had a highly significant effect on growth, yield and yield components such as plant height, branch number, node number, number of leaves per plant, leaf area, pod number per plant, average fruit weight, total fruit number per plot and fruit yield. The highest total fruit yield of 11.47 t/ha was recorded from treatment combination of N and P at the rate of 50 and 37.5 kg/ha, respectively. The maximum (150 kg/ha) Nitrogen rate resulted in luxuriant vegetative growth, reduced fruit number per plant, while application of phosphorus significantly increased fruit number per plant, fruit number per plot, total fresh fruit yield. According to the partial budget analysis, the highest net benefit (153958.16 ETB per hectare) was recorded from the combined applications of N and P at the rate of 50:37.5 kg/ha. Nevertheless, since this is a one season result at one location more researches are needed in different locations on different representative soils for more seasons to reach at conclusive fertilizer recommendation for this specific crop in the area.

“…This may be higher doses of N and P fertilizer causes drop of leaf, drop of pod and reduce the quality of Okra pod. The result is in line with Khandaker et al (2017) who reported that Okra pod weight decreased with higher dose of NPK fertilizer. 3.2.4.…”

“…Results from this experiment shows that higher rate of vermicompost enhanced the stomatal conductance of watermelon crops. According to Khandaker et al (2017), the highest value of stomatal conductivity of chilli was recorded with the application of vermicompost. It was also observed from the results the higher the net photosynthetic rate the higher the stomatal conductance.…”

A study was conducted at the teaching and research farm of the Faculty of Bioresources and Food Industry at Universiti Sultan Zainal Abidin (UniSZA) with an objective of determining the best rates for vermicompost application on red seedless watermelon var. Crimson sweet. In this research, watermelon crimson red flesh seedless variety was used as planting materials and different application rates of vermicompost were the major factor of the experiment. The research was a potted layout experiment in a completely randomized design (CRD). Sixteen (16) pots were randomly arranged in a nursery and 10 kg of BRIS soil was added in to each pot until 10 cm of soil furrow slice was achieved. Application of vermicompost at the rates of 5, 10, 15, 20 t ha-1 and untreated control were applied, with four replications each, single plant was taken as an experimental unit from each replicate. Vermicompost treatment at the rate of 15 t ha-1 increased stomatal conductance, transpiration rate and the least days required to 50% flowering was significantly different compared with other treatments and control. The vermicompost application at the rate of 20 t ha-1 positively influences leaf area, net photosynthetic rate, internal carbon dioxide, number of flowers and fruits weight of watermelon. This findings also revealed that quality properties of watermelon like rind thickeness, TSS, pH, anthocyanin, juice and ash contents were improved with the application rate of 20 t ha-1. Vermicompost application rate of 15-20 t ha-1 is recommended for watermelon production.

“…On the other side, the weakest values were resulted with plants fertilized by 50% RDF. Khandaker et al (2017) on okra demonstrated that application of NPK shows the highest values regard chlorophyll content. Nasarudin et al (2018) found that the effect of NPK on the chlorophyll contents of rice was investigated with a view to the enhancement of high yield production.…”

The current study was achieved to evaluate the influence of different NPK formulas at (20:20:20, 20:10:5 and 16:6:5), NPK rates at (2, 4 and 6 g/pot) and their interactions on vegetative growth and chemical compositions of golden photos (Epipremnum aureum). Two field experiments in a plastic greenhouse were conducted at the Nursery of Vegetables and Floriculture Department, Faculty of Agriculture, Damietta University, Egypt, during the two consecutive seasons of 2018 and 2019. The experiment was designed as a factorial in randomized complete block design, since the NPK formulas was the first factor and the NPK rates was the second factor. The obtained results cleared the importance of NPK formulas and rates on improving golden photos growth. Golden photos plants treated with NPK fertilizer formula of 16:6:5 at 4 g/pot gained significant increases in vegetative growth (vine length, vines number, leaf area, leaves number, fresh and dry weight), pigments content (chlorophyll a, b and carotenoids) and leaves macronutrients contents (N, P and K%). In general, these results may decrease the total NPK fertilization which needed for commercial production of this important foliage indoor plant through decreasing the NPK formula from 20:20:20 to 16:6:5 although increasing the NPK concentrations. Generally, from the previous results can reduce the use of compound fertilizers, especially nitrogen and phosphorus through the use of the least fertilizer equation content (16: 6: 5) and the use of fertilizer dose 4 g where there is no significant differences with the dose of 6 g so we recommend the use of 4 g /pot every three weeks where they reduce the economic cost.
