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.

修剪和养分水平对草地果园中番石榴（Psidium guajava）变种植株生长的影响阿拉哈巴德草地果园中的 Allahabad Safeda

为评估修剪和营养水平对 Allahabad Safeda 番石榴生长和产量的影响，进行了一项田间试验。处理包括四种不同的修剪水平：P0：00.0 厘米（未修剪植株/未修剪），P1：在芽长 30 厘米处修剪，P2：在芽长 40 厘米处修剪，P3：在芽长 50 厘米处修剪，以及四种不同的养分（氮磷钾）水平，即：F1：氮磷钾（260:320:260 克），P2：氮磷钾（260:320:260 克），P3：氮磷钾（260:320:260 克）、F1：氮磷钾（260:320:260 克/株）（对照），F2：氮磷钾（220:280:300 克/株），F3：氮磷钾（300:360:300 克/株）和 F4：氮磷钾（340:400:340 克/株）。在 2014-2015 年和 2015-2016 年期间，试验采用 2 因子因子随机区组设计（f-RBD），共设 3 次重复，包括 16 个处理组合。在不同处理中，T16:P3（P3：50 厘米 x F4：340:400:340 克/株）是使 Allahabad safeda 番石榴的植株高度（厘米）、每株分枝数、每株叶片数、植株蔓延（正南正北）、茎直径（毫米）、茎长度（厘米）和新芽萌发天数达到最佳无性生长参数的最佳剂量。
