Abstract
ABSTRACT
A field trial was conducted at Agronomy Research Farm, The University of Agriculture Peshawar Khyber Pakhtunkhwa during winter 2020-2021. The treatments included oat lines sown both in irrigated and rainfed conditions. The experiment was laid out in a randomized complete block design (RCBD) with split plot arrangement having three replications. The seed of oat lines were grown at the rate of 40 kg ha-1. Irrigation conditions were assigned to the main plots, while oat lines were placed in the subplots. The results indicated that maximum emergence (56 plant m-2), number of tillers (72 m-2 ), days to heading (134), days to anthesis (142), panicles (143 m-2), grains panicle-1 (158), panicle length (31.8 cm), days to physiological maturity (177), plant height (152.5 cm), lodging score (6.2 %), thousand grains weight (39 g), grain yield (3290 kg ha-1), biological yield (8579 kg ha-1), fresh weight (51746 kg ha-1), dry weight (2858 kg ha-1) and harvest index (42 %) were recorded under irrigated plots. In case of oat lines, the maximum number of tillers (91 m-2), panicles (163 m-2), grains panicle-1 (179), panicle length (36.1 cm), thousand grains weight (48 g), lodging score (6.9 %), grain yield (3521 kg ha-1), biological yield (8604 kg ha-1), harvest index (42 %) and minimum days to emergence (11), [D1] heading (116) and physiological maturity (168) were noted for Sargodha SG 2002. While the maximum plant height (158.8 cm) was recorded for Australian line and maximum fresh weight (50740 kg ha-1) was recorded for Waziristani line. However maximum dry weight (2812 kg ha-1) was noted for Sargodha SG 2002. It was concluded that oat lines Sargodha SG 2002, Australian and Chinese produced higher biological yield while oat lines Sargodha SG 2002 and Australian Grain Top produced higher grain yield and yield attributes in irrigated conditions[D2] [HR3] .
[D1]Days are not in decimal
Round up the figures
[D2]What about rainfed condition
[HR3]The data was higher only in irrigated condition so sir told me to right only irrigated condition.
