Abstract

An experiment was conducted to find out the effect of organic and inorganic sources of fertilizers on yield, quality and nutrient status of winter season guava. The two years pooled data revealed that highest soil nitrogen and phosphorous (269.97 & 19.77 kg/ha), Ca & Mg (7.03 & 2.76 meq/100 g soil), leaf nitrogen & phosphorous (1.76 & 0.26%) and leaf Ca & Mg (2.01 & 0.86%) contents, respectively, was obtained with the treatment comprising Azotobacter + 25% of N tree−1 through FYM + 75% of N tree−1 through inorganic fertilizer, whereas, the highest soil potassium (148.23 kg ha−1) and leaf potassium (1.25%) contents was obtained with the application of Azotobacter + 50% of N tree−1 through FYM + 50% of N tree−1 through inorganic fertilizer. The pooled analysis of two year data also indicates that 25% of N tree−1 through FYM + 75% of N tree−1 through inorganic fertilizer showed highest fruit yield (41.14 kg plant−1) maximum fruit length (8.39 cm), breadth (7.94 cm), weight (244.24 g) and pectin (0.81%), while, Azotobacter + 50% of N tree−1 through FYM + 50% of N tree−1 through inorganic fertilizer showed highest TSS (12.950Brix), total sugars (8.61%) and minimum physiological loss in weight (14.29%) after ten days under ambient conditions

8 of 11 groups shown: named compounds and organisms first, then groups whose results differ (checked claim by claim), then those with positive and negative results, then the smaller groups.

Claims are grouped by organism, treatment and what was measured or targeted. A paper counts as positive when any of its claims in the group is positive.
