Assessment of growth regulator and NPK fertilization effects are important tools for flower stimulation and yield improvement in cucurbits. This investigation demonstrates the comparative male-female flower induction and fruit yield of small sized bitter gourd treated with NPK fertilizers and plant growth regulators. Namely, two experiments having three replicates were conducted in a Randomized Complete Block Design (RCBD) with NPK fertilization and plant growth regulators-GA3, NAA and Ethophon application on small sized bitter gourd-genotype BG5 at the research field of the Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU). In experiment 1, different doses of NPK fertilizers comprised of 10 treatments and in that of experiment 2, different levels of plant growth regulators indicated 10 treatments. The results indicated that application of different doses of NPK fertilizer and plant growth regulators significantly (< or = 0.05) influenced over the flower initiation and fruit setting. The application of N90-P45-K60 fertilizer along with Ethophon spraying resulted in the better yield of small sized bitter gourd.
评估生长调节剂和氮磷钾施肥效果是促进葫芦科作物开花和提高产量的重要手段。本研究展示了用氮磷钾肥料和植物生长调节剂处理的小型苦瓜的雌雄花诱导和果实产量的比较情况。具体而言，在班加班杜·谢赫·穆吉布尔·拉赫曼农业大学（BSMRAU）的研究田地里，采用随机完全区组设计（RCBD），对小型苦瓜基因型BG5进行氮磷钾施肥以及施用植物生长调节剂——赤霉素（GA3）、萘乙酸（NAA）和乙烯利，开展了两个各有三次重复的实验。在实验1中，不同剂量的氮磷钾肥料构成10个处理组；在实验2中，不同水平的植物生长调节剂构成10个处理组。结果表明，施用不同剂量的氮磷钾肥料和植物生长调节剂对花的诱导和坐果有显著影响（P≤0.05）。施用N90-P45-K60肥料并喷施乙烯利，使小型苦瓜获得了更高的产量。
