Abstract:

Minimizing mineral fertilization through use of different sources of organic manure was studied on four walnut selections in temperate region of India (Kashmir) The experiment consisted of four selections [SKAU/002 (S1), SKAU/008 (S2), SKAU/024 (S2) and SKAU/040 (S2)] and six treatments [T1 (NPK recommended as per package of practices through inorganic fertilizers), T2 [100 % through manure (FYM 50% + vermicompost 25% + poultry manure 25%)], T3 (75% NPK through inorganic fertilizers + 25 % through FYM), T4 (75 % NPK through inorganic fertilizers + 25 % through vermicompost), T5 (75 % NPK through inorganic fertilizers + 25 % through poultry manure) and T6 [75 % NPK through inorganic fertilizers + 25 % through manure (1/3 FYM + 1/3 vermicompost + 1/3 poultry manure)] replicated five times and three tree in each replication in Factorial Randomized Block Design. All fertilizers and manures were applied in the first week of December beneath the tree canopy and mixed well with soil. There were significant differences in yield and nut quality parameters among different walnut selections under different treatments. Maximum yield (5.53 kg/tree) was found in selection S2 while treatment T4 showed maximum yield of 5.87kg/tree. The quality parameters of walnut were found improved by combined effect of inorganic fertilisers and vermicompost. Maximum nut length (38.65 mm), nut diameter (35.54 mm), nut weight (13.16 g), kernel length (30.77 mm), kernel breadth (23.64 mm), kernel weight (7.17 g), kernel percentage (55.56%) kernel protein content (18.31%), kernel fat content (60.39%), kernel fill (6.15 points) and kernel colour (3.32 points) was found in treatment T4. Among selections highest nut length (41.00 mm), kernel length (33.16 mm), nut weight (12.5 g) was found in S4 while as nut diameter (36.18 mm), kernel breadth and (24.01 mm) was found in S3 selection. So it seems that yield and nut quality of walnut selections could be greatly improved through fertilization of 75% fertilizer through inorganic coupled with 25% vermicompost followed by 75 % NPK through inorganic fertilizers + 25 % through poultry manure . Among the selections, S2 showed better performance with respect to yield and quality followed by selection S1.
