Abstract:

In present study a reliable data bank of nutrient concentration versus fruit yield was established from survey of litchi orchards grown in lower Himalayas (Uttarakhand, India). By using mean and standard deviation, five foliar diagnostic norms were derived as deficient, low, optimum, high and excess for each nutrient of both fruiting terminals (FT) and non-fruiting terminals (NFT) based on the principle of diagnosis and recommendation integrated system (DRIS). In FT of litchi, the optimum leaf N,P, K, Ca, Mg and S ranged from 0.79 to 1.32,0.19 to 0.41 0.57 to 0.94, 0.82 to 1.61, 0.32 to 0.45, and 0.11 to 0.18 per cent, respectively. Among, Fe, Mn, Zn, Cu B and Mo concentrations in FT of litchi ranged from 86.5 to 206.3, 11.9 to 49.3, 12.8 to 21.4, 5.62 to 13.4, 28.9 to 51.8 and 0.25 to 0.35µg/g, respectively. For NFT of litchi, the optimum leaf N, P, K, Ca, Mg and S ranged from0.65 to 1.18, 0.19 to 0.33, 0.59 to 1.03, 0.76 to 1.74, 23 to 0.50 and 0.09 to 0.15 percent, respectively. Whereas, Fe, Mn, Zn, Cu, B and Mo in NFT of litchi concentrations showed a wide range of 81.2 to 212, 16.4 to 42.8, 15.3 to 28.0, 8.9 to 14.7, 26.7 to 49.2 and 0.23 to 0.36 µg/g, respectively. The classification of the orchards based on foliar diagnostic norms in FT indicated S followed by Zn, Mo and B in FT whereas in NFT, S followed by Mo, B and Zn are most common yield-limiting nutrients in litchi. The optimum nutrient ranges developed can serve as a guide for a quick and routine diagnostic and advisory purpose for litchi orchardists of Uttarakhand.
