Impacts of Biotic and Abiotic Factors on Evaluation of Triticum aestivum L. as a Crop

Abstract

Wheat (Triticum aestivum L.) is a self-pollinating annual grass which is cultivated as staple crop widely cultivated in the world belong to the family poaceae. Wheat plays a vital role in human and animal nutrition because it is a major source of carbohydrates. Drought is a generally prolonged period of dryness which creates significant damage to crops and prevents their effective growth. It can also refer to a prolonged period of extremely low precipitation, especially one that has a negative impact on growing or living conditions. The nutritional and versatile value of wheat grain recognizes it so important that it can be refined into semolina, flour, and other products such as cookies, bread, pastries, noodles, pasta and couscous also stated that wheat is largely used to make chapatti, cakes and other food products. The germplasm was comprised of test varieties or test treatments and check varieties or control treatments. The field experiment was out by utilizing augmented block design. Parameters like germination %, tillers per plant, canopy temperature, normalized difference vegetation index (NDVI), days to 50% heading, flag leaf area (cm2), days to maturity, plant height (cm) were evaluated. Under drought condition yield/plant had positive and highly significant correlation with number of tillers, seed weight/spike and positive non-significant with NDVI, flag leaf area, days to maturity and thousand kernel weight under drought condition.
