Effect of Sowing Dates on Growth, Yield Attributes and Yield of Four Wheat Varieties

Abstract

A field experiment entitled "Effect of sowing dates on growth, yield attributes and yield of four wheat varieties" was conducted during winter season of 2016-17 on sandy loam soils of Poz-e-Ishan Research Farm of Agricultural Faculty of Baghlan University. The experiment was laid out in split plot design viz. four dates of sowing comprised of (16 th November, 01 st December, 16 th December and 31 st December 2016) as main plot treatments and four varieties (Solh 02, Gul 09, Muqawim 09, Kabul 013) as sub plot treatments with four replications. The highest plant height, number of effective per plant, test weight and grain yield of wheat was recorded with all varieties sown on 16 Nov-16, which was statistically identical with all treatments sown on 01 Dec-16 but significantly higher over rest of date of sowing. Among wheat varieties Kabul 013 and Gul 09 produced significantly higher plant height, number of effective per plant, test weight and grain yield of wheat over rest of the varieties.

Assessing the performance of wheat (Triticum aestivum L.) varieties to diverse sowing dates

“…Late-sown wheat experiences both low temperatures during early growth and high temperatures during post-anthesis, negatively affecting grain development and yield (Jadhav, 2016) [8] . Timely sowing allows for optimum crop growth, higher biomass accumulation, and increased grain and biological yield (Habibi and Fazily, 2020) [9] . Advantages of sowing at the right time include improved seed germination, plant height, spikelet number, grain weight, and test weight (Keshry et al, 2022) [10] .…”

Effect of Seeding Rates and Genetic Compositions on some Growth and Yield Traits of European Rye (Secale cereale L.)

“…which vary in their degree of response from variety to variety, especially temperature and light, Two crucial environmental elements that impact every stage of crop growth and development are: The fluctuation of these two parameters can greatly influence the duration of various stages of growth and development, particularly the flowering period and grain filling period. These two stages serve as indicators of the effectiveness of the source and sink of any crop [18]. The seeding rates used for planting per unit area, which vary depending on the type of soil, its fertility, the amount of moisture available at planting, the time and method of planting, in addition to the prevailing environmental conditions in the region, the variety to be planted, the size, purity, and germination rate of the seeds, all have a significant impact on the productivity and growth of any crop [19].…”
