ESTIMATE THE IMPACT OF THE COMBINED APPLICATION OF N AND P FERTILIZERS ON THE GROWTH OF WHEAT (TRITICUM AESTIVUM L.) UNDER THE DRY ENVIRONMENT OF UTHAL, BALOCHISTAN

Abstract

The present research study was conducted in a cool winter with a hot summer region of Lasbela, Balochistan. The main purpose of this study was to evaluate the effects of the combined application of nitrogen and phosphorus fertilizers on wheat crops, associated with growth and grain yield. Factorial combinations of three of both N and P within the control (T1= control, T2= 30&15kgha-1, T3= 60&30kgha-1, T4= 90&45kgha-1) of three times replicates were laid out in a randomized complete block design. The findings of this study showed that the increased applications of both fertilizers influence wheat's growth and yield attributes. Growth parameter results indicated that plant height (cm), leaf length (cm), pedicel length (cm), and spike length (cm) increased with an increased dose of both fertilizers i.e. 70.66, 7.12, 24.7, 6.12cm; 73, 8.56, 30.53, 7.52cm; 88.312, 11.91, 36.3 and 10.12cm respectively. Mean maximum and significant p<0.05 were recorded in T4 compared to T1, T2, and T3. In the in-comparison of T1 and T2, a minor difference was recorded. Additionally, results of biological and grain yield also increased 8-10% more than T1 and T2 with increased application of both fertilizers. Conclusively, combined applications of both fertilizations within split doses and after the application irrigation have significantly interacted with the growth, biological, and yield attributes of wheat
