Effect of nitrogen and potassium on growth parameters of banana
Journal of Bioscience and Agriculture Research , 2020
Banana (Musa spp.) is a vigorously growing, monocotyledonous herbaceous plant. Though Bangladesh is more suitable for production of banana but its productivity is very low due to a lack of improve variety, sustainable production & protection technology, soil fertility and fertilizer management. Fertilizers i.e. nitrogen and potassium are one of the most important elements that can play vital role to increase productivity of banana. Hence, the present research investigation was were studied in a randomized complete block design (RCBD) with three replications. The results revealed that the single application of N3=500g Urea/plant, K3=450g MOP/plant and their combination (N3×K3=500g urea/plant×450g MOP/plant) showed more significant increase in morpho-physiological characteristics namely pseudo-stem height (m), pseudo-stem girth (cm), number of functional leaves, total number of leaves per plant, minimum days to bunch maturity & crop duration (days) and increase in yield contributing characters viz. total number of fingers per bunch, total number of hands per bunch, bunch weight (kg/plant), yield (t/ha) and benefit cost ratio in this study. The application of these two fertilizers as single or their interaction would be the most appropriate level for getting the superior growth and yield performance of banana.

Tomato is the most commonly consumed and marketed vegetables in the world and one of the plants that respond more to fertilization, and particularly in demanding potassium, which is responsible for stomata opening, sugar translocation, protein synthesis and enzymatic activation. Analysis of nutrients contents made available to the plant and its relationship with what is present in plant tissue is a great alternative for the correct handling of mineral nutrient solutions. The objectives of this study are to evaluate the influence of increased K doses on the growth of tomato and its relationship with other nutrients. For the study, two experiments of fertirigated tomatoes in pots were preformed with sand as substrate, and five different doses of potassium, grown in a greenhouse. Nutritional content in the fruit in early development and leaf immediately above each bunch was evaluated. Data were submitted to polynomial regression analysis to the second degree. Results showed that increa...
THE EFFECTS OF ORGANIC AND INORGANIC FERTILIZERS ON THE EARLY GROWTH AND DEVELOPMENT OF
Applied Tropical Agriculture, 2019
Soil fertility is a major limitation to seedling production, hindering the growth and development of indigenous tree species in the nursery in sub-Saharan Africa. In this study, the effects of organic and inorganic fertilizers on the growth and development of Vitellaria paradoxa seedlings were investigated for six months. Using a Completely Randomized Design,six month-old uniformly growing seedlings were potted in topsoil mixed with poultry-1-1 droppings, cow dung, water hyacinth and N.P.K. 15:15:15 fertilizer at 100 kg ha and 200 kg ha dosage levels, while untreated topsoil served as control. Thetotal plant height(cm), stem collar diameter(mm) and number of leaves were assessed monthly, for six months. The data collected were subjected to descriptive and two-way ANOVA at p≤ 0.05 level of significance.The organic and inorganic fertilizers had significant main and interaction effects on the seedling growth variables measured. The highest mean total height (14.2 ± 0.07 cm), number of leaves ((9.25 ±-1 0.25)and collar diameter (4.95 ± 0.02 mm) were observed for seedlings treated with 200kg ha N.P.K 15:15:15 fertilizer. The least mean total height (11.95 ± 0.06 cm), number of leaves (6.75 ± 0.25) and collar diameter (4.26 ±-1 0.07 mm) were observed for untreated seedlings (the control), 100 kg ha poultry manure and water hyacinth, respectively. Increase in dosage levels of organic and inorganic fertilizers improved tree seedling performance. Nutrients supply from N.P.K and organic manure enhanced growth performance of Vitellaria paradoxa seedlings. Thus, they could help improve mass production of the target species in the nursery. However, organic manure which is environmentally friendly and easily accessible would also have longer residual influence on the seedling performance and reduce soil toxicity. Abstract Introduction
Nitrogen and potassium fertilization affects banana production
Research, Society and Development, 2020
Banana crop presents rapid growth and high fruit production, demanding intense fertilization, with nitrogen and potassium being the most outstanding nutrients. However, national productivity is still low, indicating the need for studies to improve the performance of this fruit. Thus, the objective of this work was to evaluate the productivity and fruit characteristics of Thap Maeo banana, second cycle, under nitrogen and potassium fertilization. Plants of the cultivar Thap Maeo were used in spacing of 2.5 m x 2.5 m. The experimental design was in randomized blocks in a 2 x 4 factorial scheme with three replicates. The combination of presence (400 kg ha -1 ) or absence of nitrogen and four doses of potassium (0, 300, 600 and 900 kg of K 2 O ha -1 ) composed the treatments. It was observed that the application of K 2 O at the best doses gave gains of 8.5; 5.9; 16.3; 50.2; 20.0 and 27.6%, respectively, for the hands per bunch, fruits per hand, fruits per bunch, fruit diameter and fruit...

In the Democratic Republic of Congo, banana is the third largest source of starch after cassava and maize and is the primary fruit crop. However, its cultivation remains secondary due to its high mineral demand, the infertility of tropical soils (ferralsol) and the low income of farmers. The dynamics of mineral elements and the understanding of its influence on crop growth are a necessity for a better use of fertilizers and an optimal crop production. The objective of this study was to evaluate the influence of organo-mineral amendment inputs on banana growth and
