Biomass Yield in Bread Wheat: The Effect of Sowing Density and Predicting Using NDVI

Abstract

This is due to approaching the upper limits of the harvest index. The study aimed to determine the effect of sowing density (SD) practices on BY in the Central Anatolian Region and the use of normalized vegetation index (NDVI) values in estimating BY easily. Field trials were carried out for three consecutive years in rainfed and irrigated conditions in Eskişehir between 2012 and 2015. Four different SDs (Sparse, Ordinary, High, and Very High) were applied to six winter wheat cultivars. Biomass samples were taken during flowering and harvesting periods. NDVI values were measured using the Green Seeker Handhold Sensor (GSHS) tool during the flowering period. In both conditions, the correlation between the NDVI values during the flowering period and the biomass yields obtained during the harvesting period was found to be positive and significant (in rainfed conditions (R = 0.837), in irrigated conditions (R = 0.786)). To obtain high BY, it is recommended that to be sowed with High SD in rainfed conditions, and Ordinary SD practices in irrigated conditions. Considering the varieties, Alpu 2001 and Harmankaya-99 stand out from the others in terms of getting high biomass yield in both conditions. In addition, it was determined that the GSHS is a reliable tool that can be used for the estimation of BY.
