Abstract

Abstract Delayed planting of sugarcane crop after harvesting of seed is a common farming practice in all cane growing areas of Pakistan. This study was conducted to find out comparative effect of sugarcane seed having different harvesting or stalling period on productivity of sugarcane. The experiment was planted in randomized complete block design with split plot arrangement for two consecutive years. Three commercial sugarcane varieties viz. CPF 248, CPF 247 and CPF 246 were kept in main plots whereas cane setts staling; fresh, 3 days, 6 days & 9 days old stale cane setts were placed in sub-plots. The data revealed that sugarcane clones were differed significantly for most of biometric traits under study except cane yield whereas impact of cane setts stalling was also significant excluding for sugar contents. While, interactive effect of all treatment combinations for sugarcane clones and cane setts stalling was found significant except for CCS%. It was found that clone CPF 247 exhibited highest cane and sugar yield by planting fresh cane setts as against lowest for CPF 248 when planted with 9 days old stale cane setts during both years of experimentation. Better growth and yield related traits were predominantly attributed to planting of fresh cane seed having better germination, tillering and cane density.

半干旱气候下陈化蔗籽对甘蔗产量的影响

在巴基斯坦所有甘蔗种植区，收获种子后延迟种植甘蔗作物是一种常见的耕作做法。本研究旨在比较不同收获期和不同滞收期的甘蔗种子对甘蔗生产力的影响。试验采用完全随机区组设计，分块种植，连续2年。3个商品甘蔗品种CPF 248、CPF 247和CPF 246在主要地块保留，甘蔗群落老化;新鲜、3天、6天和9天的陈腐甘蔗被放置在子样地。结果表明，除产量外，甘蔗无性系的其他生物特征均存在显著差异，而除含糖量外，甘蔗坐地延迟对无性系的影响也显著。而除CCS%外，所有处理组合对甘蔗无性系和蔗套失速的交互效应均显著。结果表明，在两个试验年份中，种植新鲜蔗套的CPF 247的甘蔗和糖产量最高，而种植9天陈腐蔗套的CPF 248的产量最低。较好的生长和产量相关性状主要归因于种植具有较好发芽、分蘖和甘蔗密度的新鲜甘蔗种子。
