title: Effect of available nutrients on yield and quality of pear fruit Bartlett in Kashmir Valley India.
abstract: Pear is one of the most important commercial crops grown in the Kashmir valley of India. A study was conducted during 2008 to find out the effect of available nutrients on yield and quality parameters of pear cultivar "Bartlett" which revealed that nitrogen, phosphorus and potassium exhibited significant and positive relationship with fruit length (0.882, 0.856, and 0.482 mm, respectively), diameter (0.869, 0.794 and 0.458 mm, respectively), weight (0.876, 0.825 and 0.439 g, respectively), volume (0.908, 0.806 and 0.404, Cm3 respectively) and yield (0.908, 0.764 and 0.702 kg tree(-1), respectively) however, only nitrogen and phosphorus showed similar relationship with total sugars (0.833 and 0.838% respectively). The calcium indicated significant and negative relationship with fruit diameter (-0.433) and yield (-0.589), while as it showed significant and positive correlation with fruit firmness (0.442) only. The sulphur revealed significant and positive relationship with fruit length (0.440), diameter (0.434), TSS (0.482) and yield (0.729) whereas zinc, copper, iron and manganese exhibited significant and positive relationship with fruit length (0.889, 793, 0.671 and 0.619, respectively), diameter (0.875, 0.807, 0.653 and 0.576, respectively) weight (0.881, 0.784, 0.669 and 0.615, respectively), volume (0.885, 0.832, 0.692 and 0.572, respectively) TSS (0.858, 0.761, 0.735 and 0.609, respectively), total sugars (0.853, 0.890, 0.705 and 0.517, respectively) and yield (0.777, 0.618, 0.789 and 0.701, respectively). It is therefore suggested that nutrients have effect on quality and yield of pear fruits.
