EFFECT OF ORGANIC-CUM-INORGANIC SOURCES OF NUTRIENTS ON PHYSICO-CHEMICAL QUALITIES OF GUAVA
Neelam Tiwari*, Dr. S. S. Singh, Dr. Rajesh Singh, Neeraj K. Charmkar
ABSTRACT A field experiment find out result during 2015 and 2016 to study the organic-cum-inorganic sources of nutrients on physico-chemical qualities of guava trees. Application of 100% NPK with Zn, B, Mn micronutrients and organic mulch (T4) brought about significantly highest fruit length (6.76 cm), pulp thickness (1.44 cm), seed cavity diameter (4.43 cm), number of seeds (3.47/fruit), 100-seed weight (1.36 g) and pulp-seed ratio (74.47). This was followed by T10 and T15. In case of chemical qualities, the same T4 treatment recorded highest TSS (12.21 oBrix), lowest acidity (0.53%) and ascorbic acid (157.8 mg/100 g pulp) and higher reducing and non-reducing sugars (4.85 and 3.15%, respectively) with increased storage life of fruits. The maximum N, P and K contents in leaves were found in T7 to T11 treatments. Keywords: . [Download Article] [Download Certifiate] |
