Effect of different irrigation levels on the performance of wheat

Abstract

An experiment was conducted at the research field of the Department of Agricultural Botany, Patuakhali Science and Technology University, Patuakhali under the Agro-ecological zone-13 (AEZ-13) during the period from November 2012 to February 2013. The aim of the study was to identify the most effective irrigation level for obtaining the better growth and higher yield performance of BARI Gom-25 that are suitable to cultivate under coastal region of Patuakhali, Bangladesh. So, the present study was consists of five irrigations levels including control viz. control or no irrigation (T0), one irrigation at 25 DAS (T1), two irrigations at 25 and 40 DAS (T2), three irrigations at 25, 40 and 55 DAS (T3) and four irrigations at 25, 40, 55 and 70 DAS (T4). The seeds of BARI Gom-25 were collected from the BARI, Joydebpur, Gazipur on 22 November, 2012. The experiment was laid out in completely randomized block design (RCBD) with four replications and analysis was done by the MSTAT-C package program where means were separated by DMRT at 5% level of probability. Data were recorded on various growth and yield attributing traits. The plot size was 5 m2 (2.5 × 2.0 m) where row to row and seed to seed distances were 20 and 10 cm respectively. Data were collected on various morpho-physiological growth, yield and yield attributing traits. Results obtained from the present study, whole characters of the study were significant at 5% by the moisture (irrigation) levels where three irrigations given at 25, 40 and 55 DAS had most effective than that of other moisture levels and no irrigation. From the results investigation, it was found that the tallest plant (76.86 cm), maximum requiring days to anthesis (61.00 days), maturity (109.0 days) and maximum number of effective tillers (5.00 hill-1),the highest grain growth (3.11g at 36 DAA) and grains (44.00 spike-1) were obtained with three irrigation (T3) levels. Similarly, T3 further showed the greater performance on spike length (17.28 cm), 1000-seed weight (50.16 g), grain (4.16 t ha-1), straw (5.89 t ha-1) and biological yield (10.05 t ha-1) as well as the higher harvest index (41.39%). Investigated above whole characters were produced lower performances under no moisture (irrigation) treatments. These results indicated that irrigation at three times (T3) would be most advantageous irrigation levels for wheat production under the studied non saline ecosystem of coastal region.Progressive Agriculture 29 (2): 99-106, 2018

Characterization on Physical, Mechanical, and Morphological Properties of Indian Wheat Crop

“…The wheat properties can be affected by the various factors such as the type of soil, type of irrigation, and climatic variations. Earlier published research states that the height of the plant can be significantly increased by providing three irrigations at 25, 40, and 55 DAS [34]. In addition, there is a 40% loss in wheat crop yield due to lack of nutrient scarcity and presence of metal content in the soil [35,36].…”

Influence of irrigation regimes and nitrogen fertilizer management on the performance of spring wheat in Bangladesh

“…Shirazi et al (2014) [15] observed that plant height was gradually increased with increasing number of irrigations. Islam et al (2018) [16] and Rummana et al (2018) [17] also observed similar results. Patel et al (1992) [18] explained that 12 cm depth of irrigation significantly increased the plant height compared with 6 cm irrigation.…”

“…While, Leghari et al (2017) reported irrigation treatments had significantly affected plant height. Moreover, Islam et al (2018) reported that wheat yield increased with increasing irrigation treatments.…”
