Background: Meconium staining of amniotic fluid harms newborns. Pregnant women in Palangka Raya City have the habit of consuming young coconut water to prevent the meconium staining of amniotic fluid. Young coconut water contains the highest mineral potassium. Potassium can affect the intestinal peristaltic.Objective: Analyzing the effect of potassium of young coconut water consumed by pregnant women in the third trimester on the levels of potassium saliva of mothers and the newborn and meconium levels of amniotic fluid.Methods: This study was a prospective cohort study of third-trimester pregnant women. The study sample was taken randomly, 24 pregnant women who consumed young coconut water and 24 who did not consume young coconut water.Results: Potassium levels of young coconut water had a positive correlation with levels of maternal salivary potassium (b = 0,414, p = 0,000). Maternal salivary potassium levels had a negative correlation with meconium levels of amniotic fluid (b = -0,603, p = 0,000). Maternal salivary potassium levels through infant salivary potassium levels had a negative correlation with meconium levels of amniotic fluid (b= -0,205, p = 0,000). Conclusion:Young coconut water consumed by pregnant women during the third trimester can prevent the meconium staining of amniotic fluid

“…Another approach to diagnosing K status is to analyze the K content of plant sap. Sap is extracted by pressing plant tissue with tools such as a pliers (Syltie et al 1972), a garlic press (Gangaiah et al 2016), or a press attached to a syringe (Burns and Hutsby 1984). Freshly sampled petioles and leaf midribs are the typical samples.…”

“…Some studies focus on correlating sap K concentration to leaf K concentration and do not include correlations to yield. This is often done in exploratory studies examining new analytical methods (Gangaiah et al 2016;He et al 1998;Iseki et al 2017). Eventually, however, each new method must be correlated to yield or some metric of crop performance.…”

Several methods exist for evaluating plant nutritional status. Looking for visual deficiency symptoms is perhaps the simplest approach, but once symptoms appear, crop performance has already been compromised. Several other techniques have been developed. All of them require correlation studies to provide plant performance interpretations. Reflectance is a remote sensing technique that detects changes in light energy reflected by plant tissue. It has proven successful in detecting nutrient deficiencies but does not yet have the ability to discriminate among more than one deficiency. Chemical assays of leaf tissue, known as tissue tests, require destructive sampling but are the standard against which other assessments are compared. Sufficiency ranges provide concentrations of each nutrient that are considered adequate for crop growth and development. They consider nutrients in isolation. Other approaches have been developed to consider how the concentration of one nutrient in tissue impacts the concentrations of other nutrients. These approaches strive to develop guidelines for maintaining nutrient balance within the plant. All approaches require large data sets for interpretation.

“…However, foliar analysis indicates an average value from the beginning of the growth cycle until the time the sample is taken and consequently many effects overlap and make the knowledge of cause/effect relations difficult (Cadahía 2008). Despite being a very good tool to detect deficiency and/or excess of nutrients along with the soil samples analyzed from the same site (Milošević and Milošević 2017), this analysis is costly and time consuming (Gangaiah et al 2016). Monitoring crop and soil nutrient status with quick analysis is a favorable approach for corrective management (Thompson et al 2009).…”

“…The majority of plant analysis is performed by inductively coupled plasma optical emission spectroscopy (ICP-OES) or by inductively coupled plasma mass spectrometry (ICP-MS) (Hansen et al 2013). The laboratory method is always destructive and implies dissolving the sample in at least one acid (Gangaiah et al 2016), usually nitric acid.…”

Sap quick tests are well established in vegetable crops. However, there is less equivalent investigation for perennial crops, such as apple trees. Accessing the nutrient content, as opposed to the foliar analysis, would increase the opportunity of adjusting the fertilization, along the growing cycle. This work evaluates the relation between the NO 3 −, K + , Ca 2+ , Mg 2+ , PO 4 3and NH 4 + contents in apple petiole sap, measured with the RQflex ® test strips and laboratory methods to assess the possibility of using this tool with accuracy in in-situ sap analysis. Petiole samples were collected from six apple tree orchards, frozen and pressed. Dilution was mandatory for all nutrient determination, except NO 3 − . The dilution factor varied with the stage of the annual cycle. The levels of NO 3 − , K + , Mg 2+ , and Ca 2+ followed the same pattern during the growing cycle, with both methods. Regression analysis resulted in high determination coefficients for NO 3 − (R 2 = 0.85), K + (R 2 = 0.86), Mg 2+ (R 2 = 0.81) and Ca 2+ (R 2 = 0.95), between RQflex ® and laboratory methods. No equivalent relation was found for ammonium and phosphate determination. These tests can be useful tools for rational fertilization management, mainly in high-density apple orchards. The calcium content in 45 DAFB leaves correlated well with the calcium content in sap at the same timing.
