one production factor influences the response to another factor. A positive interaction occurs when the influence of the combined practices exceeds the sum of the influences of the individual practices. Such positive interactions have served as the science-based justification for development of a “balanced” plant nutrition program. Positive interactions with P and other nutrients are well docum...

Plant growth-promoting rhizobacteria (PGPR) of the genus Pseudomonas have been reported to increase the yield of nonleguminous plants. Inoculation with Pseudomonas has been found by some authors to improve nodulation of legumes. This work examined the response of various legumes to a combined inoculation with Pseudomonas and nodule bacteria in pot experiments under field conditions in gray fore...

Establishment of the effectiveness organic micronutrient complex on growth and biological mass juniper (Juniperus sabina L.) seedlings in an enclosed ground UNPK “Agrocenter” was purpose study. The application increased current seedlings, root neck diameter, system length total height planting material juniper. Close interdependence between dose fertilizer used is determined by coefficients det...

this fertility experiment was carried out using split plots based on a randomized complete block design of three replications in 2006 at sari agricultural sciences and natural resources university. the aim of the experiment was to investigate some macronutrient and micronutrient accumulation in leaves of different soybean cultivars as influenced by some organic fertilizer types and levels. main...

The growth responses of alfalfa (Medicago sativa L.) to azomite, a natural composite earth mineral, were assessed in greenhouse experiment at Virginia State University, Chesterfield, VA. Alfalfa plants raised on lime-amended Bojac, Bourne, Emporia and Cullen soils that received 224 kg K/ha 14 × 16 cm pots. Azomite, micronutrients fertilizer, was applied 0, 200, 400, 600 kg/ha replicated three t...

Abstract In the context of black soldier fly (BSF) rearing, often residues from production — mainly faeces but also undigested substrate are addressed as frass in a broader sense. As BSF is expanding, valorization organic fertilizer gaining importance. However, contrast to established fertilizers, little known on properties and variation this by-product, which essential for assessing possible a...
