Abstract:
... Chemical analysis of leaves is an effective tool for detecting nutritional imbalances and providing data for fertilizer recommendations. Therefore, it is extremely important to establish criteria for interpreting these results. The DRIS (Diagnosis and Recommendation Integrated System) method is an alternative to the interpretation of results of leaf analysis as it allows the calculation of indexes ...

Diagnosis and Recommendation Integrated System; Musa; bananas; calcium; fertilizers; magnesium; nitrogen; nutrient deficiencies; nutrient-nutrient interactions; phosphorus; potassium; soil fertility; Uganda
Abstract:
... Despite low yields and soil fertility problems, fertilizer use in the East African Highland banana (AAA-EA) production is absent. High fertilizer costs increase the need for site-specific fertilizer recommendations that address deficiencies. This study aimed to derive and compare norms for AAA-EA bananas, using Compositional Nutrient Diagnosis (CND), Diagnosis and Recommendation Integrated System ...

Abstract:
... Low soil fertility is one of the main constraints to crop production in the West African savanna. However, the response of major cereals to fertilizer applications is often far below the potential yields. Low fertilizer efficiency, inadequacy of current fertilizer recommendations, and the ignorance of nutrients other than N, P, and K may limit crop production. Nutrient limitations to maize product ...

Diagnosis and Recommendation Integrated System; annuals; fertilizer requirements; fertilizers; leaves; magnesium; nutrient balance; nutrient content; nutritional status; perennials; product quality; soil test values
Abstract:
... For annual plants, leaf analysis cannot replace soil testing in order to determine their fertilizer requirements. In contrast, leaf nutrient concentrations of perennial plants, since they grow in rotations of 10 to 30 years, with no change in species and with changing soil test values, often reflect, excepting annual fluctuations, the fertility status of sites. The compositional nutrient approach ...

Abstract:
... Foliar analysis has been practiced widely in sugarcane (a complex trispecies hybrid of Saccharum) for planning and evaluation of fertilizer programs and harvest schedules. On the mainland of the USA, sugarcane farmers have traditionally relied on soil testing to plan fertilizer programs. Soil testing remains an excellent preplant practice but its reliability for the successive ratoon crops has bee ...

In order to eliminate possible imbalances among nutrients, the Diagnosis and Recommendation Integrated System (DRIS) was adapted to monitor the nutritional status of sugarcane in an experiment with varying P and K levels. Standard DRIS reference norm ...

Abstract:
... A long-term experiment using corn (Zea mays L.) was initiated in 1973 on calcareous strip-mine spoil to evaluate the effects of anaerobically digested sewage sludge on the spoil-crop system. Treatments consisted of a check (336-224-112 kg ha⁻¹ year⁻¹ N-P-K) and sewage sludge applications, weather permitting, at weekly rates of 0.64, 1.27, and 2.54 cm. In 5 years, 1973–1977, a total of 258 dry t ha ...

Abstract:
... The Crop Log system of sugarcane (Saccharum spp. hybrid) tissue analysis is a critical concentration approach which is widely used for the diagnosis of nutrient deficiencies and imbalances in the Hawaii sugar industry. Recent studies conducted elsewhere suggest that the Diagnosis and Recommendation Integrated System (DRIS), which utilizes ratios of tissue nutrient concentrations rather than the co ...
