Determining the Relationship between SPAD Values and Common Bean Seed (Phaseolus vulgaris L.) Yield by Correlation and Path Coefficient Analysis Method by using Different Organic Fertilizer

Abstract

Path coefficient analysis provides a much better understanding of the correlation coefficient values. Spad values give information about the state of the leaf. In the study path coefficient analysis was performed especially SPAD values in beans. The study was carried out Kahramanmaraş Sutcu Imam University treatment area in 2021 year. Mispir cultivar Aydintepe local common bean genotype were used Leonardite chicken litter their mixture were used various doses (3,6,9 t ha-1conventional fertilizer (25 kg ha-1 N / 64 kg ha-1 P2 O5 ) control application) were added to the soil. Leaf chlorophyll content was measured in three periods: early leaf (1st SPAD) flowering stage (2nd SPAD) post-flowering (3rd SPAD). In addition seed yield biomass yield values were determined. Chicken Manure 3 t ha-1 organic fertilizer application showed the best performance among all applications in terms of seed yield. the Aydintepe local genotype showed higher performance than the Mispir cultivar for the most of the properties examined.
