Abstract

Flood based irrigation is a unique system practiced in the foothill plains of Suliaman ranges of western mountains of Pakistan.. In the current research, effect of tillage practices on the soil characteristics, different wheat genotypes and their attributes along with farmer economics were studied. The field trial was conducted at a farmers field with randomized complete block design with split plot sequence having genotypes in the main plots while tillage operation in the sub – plots. Three wheat genotypes including two improved varieties i.e. Pirsabak – 15 and Fateh Jhang and a single landrace were sown. Tillage operations included deep plough, conventional tillage, mulch tillage and zero – tillage. The results showed that soil tillage significantly influenced the physico – chemical characteristics of soils. The interaction between genotype and tillage also exhibited significant effect except for soil pH and total soil nitrogen. The agronomic parameters showed significant effect of both varities, tillage practices and their interaction except for total biomass. The grain protein content showed significantly higher total protein (13.61%) in the landrace as compared with the improved varieties. The BCR calculated at the harvest of the experiment showed that 3.86 for the local landrace with deep plough and the least was observed 2.96 in the improved variety (Fateh Jhang) on zero tillage plots. It may be concluded from the results that improved variety (Pirsabak) gave better result in term of yield. Landrace also showed a good response to tillage.

洪水耕作制度下不同小麦基因型对耕作方式的响应
洪水灌溉是巴基斯坦西部苏里亚曼山脉丘陵平原上的一种独特的灌溉系统。研究了不同耕作方式对土壤性状、不同小麦基因型及其性状的影响,以及对农户经济效益的影响。田间试验在一个农户田间进行,采用随机完全区组设计,分地块序列,主地块为基因型,次地块为耕作。播种了三个小麦基因型,包括两个改良品种,即Pirsabak - 15和Fateh Jhang和一个地方品种。耕作作业包括深耕、常规耕作、覆盖耕作和免耕。结果表明,土壤耕作对土壤理化性状有显著影响。除土壤pH和土壤全氮外,基因型与耕作方式的交互作用也有显著影响。除总生物量外,农艺参数对品种、耕作方式及其互作均有显著影响。地方品种籽粒蛋白质含量显著高于改良品种(13.61%)。试验收获时计算的BCR表明,深耕地方品种为3.86,免耕改良品种为2.96。结果表明,改良品种(Pirsabak)在产量方面表现较好。长白猪对耕作也表现出良好的反应。
