Effect of different irrigation intervals on the performance of wheat (Triticum aestivum L.) in ecological zone of Rahim Yar Khan
A field experiment was conducted to study the response of wheat to different irrigation intervals on the performance of wheat at Adaptive Research Farm, Rahim Yar Khan during 2020-2021 and 2021-2022 in Randomized Complete Block Design (RCBD). Five irrigations intervals were checked out i.e (1 irrigation at crown stage, 2 irrigations at crown and tillering stage, 3 irrigations at crown, tillering and booting stage, 4 irrigations at crown, tillering, booting and milking stage and 5 irrigations at crown, tillering, booting, milking and grain filling stage. Results revealed that application of different irrigation intervals to wheat crop affected the number of tillers (m-2), plant height (cm), 1000 grain weight (g), and grain yield (kg ha-1) significantly, while non-significant effect was observed on other parameters i.e germination count (m-2). From the two years average results, maximum grain yield (4365.7 kg ha-1), number of tillers (380.5m-2), plant height (105.2cm) and 1000 grain weight (44.5g) were recorded from the plots where 4 irrigations at crown, tillering, booting and milking stage was applied.
Key words: irrigation, wheat, grain yield and thousand grain weight.
