Abstract
A field experiment was conducted to evaluate the effect of pruning and nutrient levels on growth and yield of guava cv. Allahabad Safeda. The treatment consists of four different levels of pruning P0: 00.0cm (Un-pruned plants/ Without Pruning), P1: Pruned at 30cm of the shoot length, P2: Pruned at 40cm of the shoot length and P3: Pruned at 50cm of the shoot length and four different levels of nutrients (NPK) viz., F1: NPK (260:320:260 g/plant) (Control), F2: NPK (220:280:300 g/plant), F3: NPK (300:360:300g/plant) and F4: NPK (340:400:340g/plant). The experiment comprising 16 treatment combinations was laid out in 2-factor Factorial Randomized Block Design (f-RBD) having three replications during 2014-2015 & 2015-2016. Among the different treatments T16:P3(P3: 50cm x F4: 340:400:340 g/plant) was best dose for optimum vegetative growth parameter viz., plant height (cm), number of branches per plant, number of leaves per plant, plant spread (n-s & e-w), stem diameter (mm), stem length (cm) and days to taken new shoot emergence of guava cv. Allahabad safeda.
