Abstract

A field experiment was carried out with different treatment combinations of organic manures (FYM @ 25 and 50 kg, vermi-compost @ 5 kg and organic mulch 10 cm thick per plant), inorganic fertilizers (full dose of recommended NPK, 50% dose of recommended NPK), bio-fertilizers (Azospirillum, Azotobacter, Pseudomonas flourescence Aspergillus niger etc.) and foliar spray of micronutrients on eight-year-old guava trees cv. Sardar under high density planting. The results revealed that the application of 50 percent dose of recommended NPK + 50 kg FYM + 250 g Azotobacter (T7) significantly increased the canopy volume (201.42 m3), fruit weight (153.30 g), TSS (14%), ascorbic acid (198.30 mg/100 g pulp), reducing sugar (4.77%), total sugars (8.10%), leaf nitrogen (1.40%), phosphorus (0.46%), potassium (1.17%) contents and fruit yield (28.95 kg per plant). Nitrogen, phosphorus and potassium content of the leaf were positively correlated with fruit yield. Further, regression analysis revealed that fruit weight (r2 = 0.914) dominantly influenced the fruit yield and leaf nitrogen content also influenced (r2 = 0.499) fruit yield significantly. The combined application of 50 percent dose of recommended NPK + 50 kg FYM + 250 g Azotobacter (T7) gave significantly higher fruit yield plant−1 (28.95kg) with higher B: C ratio (2.53:1).

8 of 10 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.
