The dataset explained the details on how pruning techniques significantly affected the seasonal variations on fruit availability and edible quality of guava ( L.) under fluctuating sub-tropical weather conditions. The present pruning data also directed a way of enhancing lean season (off-season) harvest without sacrificing the main season yield and fruit quality. In detail, the pruning strategies included branch removal of 0 cm, 15 cm, 30 cm and 45 cm from shoot-tip once a year during spring (early March), monsoon (early June) and autumn (early September) starting with spring pruning. Over two consecutive years (2019-2020 and 2020-2021), the pruning treatments were assigned in triplicates following a randomized Complete Block Design (RCBD) where the same plants received the same treatments during observation period. Data on crop load like number of fruits and fruit yield per plant and fruit biochemical traits namely total soluble solids, titratable acidity, total sugars, vitamin C and fruit specific gravity were recorded. To assess the seasonal variations, data collection was performed continuously and grouped at quarter intervals i.e., March-May, June-August, September-November and December-February of the year. Plants under pruning produced greater number of flowers and fruits for superior yield and quality compared to non-pruned plants. Irrespective of pruning techniques, June-August and September-November quarters had superior yield over others, whereas March-May harvests retained utmost fruit quality. Considering pruning time, plants reserved maximum harvestable fruits in June-August quarter under spring pruning followed by March-May quarter for autumn pruning compared to other combinations. Moreover, fruit biochemical attributes were examined the best at March-May harvests under autumn pruning. Alongside, June-August and September-November periods exhibited superiority for yield over others when plants were pruned at 30 cm level, but 45 cm pruning had best yield at March-May quarter. Whether, fruits had notable TSS, sugars, vitamin C and specific gravity obtained during March-May period from 45 cm pruning treatment. June-August was noted to produce inferior quality fruits in guava.
该数据集解释了在亚热带天气条件波动的情况下，修剪技术如何显著影响番石榴（L.）果实供应量和可食用品质的季节性变化。目前的修剪数据还指明了一种在不牺牲主季产量和果实品质的前提下提高淡季（非主季）收成的方法。详细而言，修剪策略包括在春季（3月初）、季风季节（6月初）和秋季（9月初），从梢尖开始每年一次去除0厘米、15厘米、30厘米和45厘米的枝条，从春季修剪开始。在连续两年（2019 - 2020年和2020 - 2021年）中，按照随机完全区组设计（RCBD）将修剪处理设置为一式三份，在观察期内相同的植株接受相同的处理。记录了作物负载数据，如单株果实数量和果实产量，以及果实生化特性，即总可溶性固形物、可滴定酸度、总糖、维生素C和果实比重。为了评估季节性变化，数据收集持续进行，并按季度间隔分组，即每年的3 - 5月、6 - 8月、9 - 11月和12月至次年2月。与未修剪的植株相比，经过修剪的植株产生了更多的花和果实，从而获得更高的产量和品质。无论采用何种修剪技术，6 - 8月和9 - 11月季度的产量高于其他季度，而3 - 5月收获的果实品质最佳。考虑修剪时间，与其他组合相比，春季修剪的植株在6 - 8月季度保留了最多的可收获果实，其次是秋季修剪的3 - 5月季度。此外，秋季修剪时，3 - 5月收获的果实生化属性检测结果最佳。同时，当植株在30厘米水平修剪时，6 - 8月和9 - 11月期间的产量高于其他时期，但45厘米修剪在3 - 5月季度产量最高。无论如何，3 - 5月期间从45厘米修剪处理获得的果实具有显著的总可溶性固形物、糖分、维生素C和比重。6 - 8月被认为番石榴果实品质较差。
