Abstract:

Apple cultivation in Japan typically involves the use of chemical fertilizers and pesticides which can damage the environment. Therefore, in this study we investigated the orchard soil biochemical characteristics as well as the fruit nutrient contents, and pesticide residues of apples grown either organically (organic fertilizers + reduced pesticides) or with conventional chemical fertilizers and pesticide rates. Compared with conventional chemical fertilizer treatment, the organic fertilizer treatment produced fruit with significantly higher contents of sugar, as well as soil with higher tota

A study to assess the effects of fertilizer application on either coconut or coffee or both, in an intercropping system was conducted from 1985 to 1991. at the Davao Research Center, Mindanao, Philippines. The coconuts were planted at 8 m x 8 m square system.  Fertilizer application on coconut intercropped with either fertilized or unfertilized coffee increased copra yield significantly. A very slight increase in copra per nut was noted on un‑fertilized coconut even with fertilized coffee intercrop indicating coconut did not benefit from the fertilizers applied on coffee. Bean yie

Abstract:

Intensification of horticulture in Russia involves planting of new high-density orchards with drip irrigation and fertigation as well as intensification of the exploitation of traditional orchards. This approach involves an increase in mineral fertilizer application imposing the risk of soil fertility loss. For several reasons, the use of traditional organic fertilizers like manure in orchards is currently marginal. Although bacteria-based biofertilizers cannot substitute mineral fertilizers completely, they can significantly reduce the need for mineral fertilizer application. The effect of mi

Under intensive cropping systems in the tropics, application of chemical fertilizers becomes an apparently indispensable means of replenishing the rapidly depleting soil nutrients. However, the reported side effects of continuous application of synthetic fertilizers on soil and man are now a major concern. Hence, determination of the potentials of some easily exploitable natural or organic-based fertilizer material(s), which can effectively compete with the commonly used synthetic fertilizers like NPK 15-15-15, is a worthwhile scientific approach, not towards improved performance of versatile

Abstract:

Abstract The application of chemical fertilizers on the grain bean crop must be done due to the plant peculiarities (high consumption of nutrients, root system underrepresented, plant ability to synthesize up to 85% of the needed nitrogen) and its high sensitivity to stress conditions. Although the bean requirements for nutrients are high, the plant response to the application of fertilizers is smaller, the obtained production increase will vary widely depending on the type of fertilizer, the applied dose, but also on the climatic conditions in the area.

Abstract:

Slow-release nitrogen (N) fertilizers offer many potential benefits for vegetable production. In sandy soils, their use may lessen N leaching. If the slow-release fertilizer has a release pattern that matches crop needs, N uptake by the growing crop may become more efficient. Additionally, if slow-release fertilizers can be applied as a preplant application, production costs could be lessened, eliminating the need for multiple applications of soluble N fertilizer. Synthetic slow-release fertilizers can be separated into two general groups: those that are slow release as a byproduct of a chemic

The objective of this paper is therefore to review the effect of N fertilizers on sesame growth and productivity. Growth and yield of sesame are greatly influenced by the application of N fertilizer.
