In this study, the performance of three different statured wheat cultivars viz. Faisalabad-2008 (standard height and low tillering, SHLT), Td-1 (low height and high tillering, LHHT) and Galaxy-2013 (standard height and high tillering, SHHT) was evaluated under five different crop establishment methods including broadcasting, line sowing, no-till sowing, bed planting and ridge sowing. The experiment was conducted at the Post-graduate Agricultural Research Station, University of Agriculture, Faisalabad, Pakistan for two consecutive growing seasons of 2016–17 and 2017–18 in randomized complete block design with a split plot arrangement having three replications. The lowest time to 50% emergence (9.34 days), mean emergence time (10.18 days), highest productive tillers (316.9 m−2) and grain yield (4.11 t ha−1) were recorded in bed planted wheat. The grain yield of bed-planted wheat was 5–15% higher than other sowing methods. Among wheat cultivars, the highest net assimilation rate (4.75 g m−2 day−1), grain weight (38.65 g), grain yield (4.1 t ha−1) and mineral uptake (120.7 kg ha−1 nitrogen, 16.31 kg ha−1 phosphorus and 139.2 kg ha−1 potassium) were recorded in the cultivar Galaxy 2013 (SHHT). The interaction of cultivars and sowing indicated the cultivar Galaxy 2013 (SHHT) planted on beds produced the highest grain yield (4.55 t ha−1) and had the highest water productivity (1.99 kg m−3) whereas the lowest grain yield (3.10 t ha−1)from cultivar Td-1 (LHHT) planted on the ridges. The highest net benefits and benefit–cost ratio were noted from all sowing methods with the cultivar Galaxy 2013 (SHHT) except in the ridge sowing where cultivar FSD-2008 (SHLT) remained better for net benefits (418.6 $ ha−1) and benefit–cost ratio (1.50) than other statured wheat cultivars. The findings of this study indicated that optimization of plant stature to different tillage seedbeds may present a new opportunity for increasing their productivity.

不同耕作方式下小麦品种的表现

在这项研究中,三个不同的小麦品种的表现,即Faisalabad-2008(标准高度和低分蘖,SHLT)、Td-1(低高度和高分蘖,LHHT)和 Galaxy-2013(标准高度和高分蘖,SHHT)在五种不同的作物建立方法下进行了评估,包括广播、线播种、免耕播种、床上播种和垄播。该试验在巴基斯坦费萨拉巴德农业大学研究生农业研究站进行,连续两个生长季节为 2016-17 和 2017-18,采用随机完整区组设计,裂区布置具有三个重复。出苗 50% 的最低时间(9.34 天),平均出苗时间(10.18 天),分蘖最高产(316.9 m -2) 和谷物产量 (4.11 t ha -1 ) 记录在床上种植的小麦中。床栽小麦的籽粒产量比其他播种方法高 5-15%。在小麦品种中,最高的净同化率(4.75 g m -2  day -1)、粒重(38.65 g)、粮食产量(4.1 t ha -1)和矿物质吸收(120.7 kg ha -1氮,16.31 kg ha -) 1磷和 139.2 kg ha -1钾)记录在栽培品种 Galaxy 2013 (SHHT) 中。品种和播种的相互作用表明,种植在床上的品种 Galaxy 2013 (SHHT) 产生了最高的谷物产量(4.55 t ha -1)和最高的水分生产力(1.99 kg m -3) 而最低的谷物产量 (3.10 t ha -1 ) 来自种植在山脊上的栽培品种 Td-1 (LHHT)。使用品种 Galaxy 2013 (SHHT) 的所有播种方法都注意到最高的净收益和收益成本比,除了在垄播中,品种 FSD-2008 (SHLT) 在净收益 (418.6 $ ha -1 ) 和收益方面保持更好–成本比(1.50)比其他成熟的小麦品种。这项研究的结果表明,根据不同耕作苗床优化植物体型可能为提高其生产力提供新的机会。
