Research Data for: Studies on High Density Planting and Nutrient Requirement of Banana in Different States of India

Data related to the article on the high density planting (HDP) and nutrient requirement of banana, conducted under the ICAR-All India Coordinated Research Project on Fruits, is being shared. The experiment was carried out at six research centers across different regions of India, including Bhubaneswar, Gandevi, Jalgaon, Jorhat, Kannara, and Mohanpur. The study aimed to increase banana productivity and farmers' profit by exploring the intervention of plant density and nutrition levels while maintaining regional choices of variety and production systems. The experiment employed a randomized block design (RBD) with four planting densities (S1P2, S1P3, S2P2, and S2P3) and three nutrition levels (F1, F2, and F3) compared to region-specific conventional practices as the control. The results showed that high density planting (S1P3) with a density of 5,000 plants per hectare and three suckers per hill at a spacing of 2m x 3m significantly increased banana productivity at the Bhubaneswar, Gandevi, Jorhat, Kannara, and Mohanpur centers. The productivity increase ranged from 28.9% to 50.6% at Bhubaneswar, 15.2% to 21.9% at Gandevi, 4.0% to 7.4% at Jorhat, 33.5% to 43.5% at Kannara, and 46.5% to 79.0% at Mohanpur. The nutrient requirement varied across centers, with 100% recommended dose of fertilizer (RDF) at Kannara, 75% RDF at Bhubaneswar and Mohanpur, and 50% RDF at Gandevi and Jorhat. These findings suggest potential cost savings of 25% to 50% for fertilizer input. To ensure higher productivity and profitability for farmers, it is recommended to implement high density planting (5,000 plants/ha) with three suckers per hill at a spacing of 2m x 3m and specific nutrient levels in the respective agro-climatic regions. The shared data provides valuable insights into optimizing banana cultivation practices and supports evidence-based decision-making in horticultural sciences.

本次共享的是依托印度农业研究理事会全印度水果协同研究项目（ICAR-All India Coordinated Research Project on Fruits）开展的香蕉高密度种植（High Density Planting, HDP）与养分需求相关研究的实验数据集。该实验在印度不同区域的6个研究中心开展，包括布巴内斯瓦尔、甘德维、贾尔冈、焦尔哈特、坎纳拉与莫汉普尔。本研究旨在通过优化种植密度与养分管理水平，同时保留各区域主推品种与种植体系的本土化选择，提升香蕉单位面积产量与种植户收益。本次实验采用随机区组设计（Randomized Block Design, RBD），设置4种种植密度（S1P2、S1P3、S2P2及S2P3）与3种养分水平（F1、F2、F3），并以各区域常规种植模式作为对照。实验结果表明，在布巴内斯瓦尔、甘德维、焦尔哈特、坎纳拉与莫汉普尔中心，采用株距2米×3米、每公顷种植5000株、每穴留3个吸芽的高密度种植模式（S1P3），可显著提升香蕉单位面积产量。各中心的产量提升幅度分别为：布巴内斯瓦尔28.9%~50.6%、甘德维15.2%~21.9%、焦尔哈特4.0%~7.4%、坎纳拉33.5%~43.5%，莫汉普尔则达46.5%~79.0%。不同研究中心的养分需求存在差异：坎纳拉需施用100%推荐施肥量（Recommended Dose of Fertilizer, RDF），布巴内斯瓦尔与莫汉普尔需75% RDF，甘德维与焦尔哈特仅需50% RDF。上述结果表明，该方案可实现肥料投入成本25%~50%的潜在节约。为进一步提升种植户的香蕉产量与种植收益，建议在对应农业气候区域内，采用株距2米×3米、每公顷种植5000株且每穴留3个吸芽的高密度种植模式，并配合适配区域的特定养分管理方案。本次共享的数据可为香蕉栽培模式优化提供宝贵参考，同时为园艺科学领域的循证决策提供支撑。
