The objective of the present study is to investigate the impact of spraying boric acid on vegetative and reproductive growth of ‘Camarosa’ strawberry (Fragaria × ananassa Duch.). The strawberry plants were sprayed with Boric acid at 0 (control), 50 and 100 mg L-1 at 30 days after planting. In general, results indicated that spraying plants with boric acid had a significant effect on yield, frui...

The aim of this work is to explore the suitability of the complementary use of mass spectra and the corresponding statistical analysis (principal components-Pareto analysis (PCA) and discriminant analysis (DA)) of these spectra to differentiate diverse humic samples as a function of their structural and conformational features. To this end, the mass spectra of humic samples belonging to the mai...

Organic compounds including seaweed extract were applied in organic production system and sustainable agriculture. One of these compounds is humic acid that was used widely in research and commercial programs. Humic acid is an organic acid obtained from humus and other natural resources with hormonal effects and improving nutrient absorption, increasing root and shoot biomass. In order to inves...

Increasingly, products containing humic substances are appearing in the turf industry market claiming to reduce water and fertilizer use by increasing soil moisture and nutrient availability. Humic acid is the most common humic substance that has been studied, but results have been highly variable (Cooper et al.; 1998).The response of humic acid is difficult to interpret due to confounding effe...

introduction drought stress is one of the most yield reduction factor of lima bean where effects on the more than 60% of bean world production. in this regard, solutions that help increase productivity with high water efficiency in this region can change the agricultural crop production. one of the solutions is using organic materials (acid humic). humic acid with linkage of water molecules and...
