dc.description.abstract | Potassium (K) is the key nutrient required in large quantity for optimum yield and quality of tobacco (Nicotiana tobacum L.) grown on K deficient Alfisols under NLS conditions. Identification and use of genotypes efficient in K uptake and utilization may be a promising strategy to improve yield and reduce costly input of K fertilizers (SOP) in FCV tobacco production. A field experiment on K deficient Alfisols at CTRI Regional station, Jeelugumilli was conducted to evaluate FCV tobacco genotypes for their potassium use efficiency. Treatments for the field experiment included eighteen FCV tobacco genotypes (16/103, Mc Nair-12, CM-12, Kanchan, NLSH-1, NLST-2, NLST-3, NLST-4, TOBIOS-2, RT-301, RT-36-1, RT-42-1, RT-47-1, RT-51-2, RT-57-1, RT67-3, RT-90-1, RT-102-1) grown with and without 120 kg K2O/ha. Plants were harvested treatment wise at the age of 65 DAT. Data on dry matter yield, K concentration and uptake in different plant parts were recorded. K use efficiency was computed in terms of agronomic efficiency (AE), physiological efficiency (PE), recovery efficiency (RE) and internal use efficiency (IUE). Results revealed that in absence of K addition, all the genotypes showed a significant reduction in biomass production. Among the genotypes highest shoot biomass was recorded for RT-51-2 highest biomass. Genotypes showed differential yield response to applied potassium. Among the genotypes RT-51-2, RT-57-1and TOBIOS2 recorded higher AE and RT-57-1, RT-47-1, RT-673 and Kanchan showed greater PE. The RE and IUE were highest in RT-51-2 and NLST-3 respectively. Based on AE and IUE genotypes are classified as efficient and responsive (ER), non efficient and responsive (NER), efficient and non-responsive (ENR) and non-efficient and non-responsive (NENR). In this study ER genotypes were Mc Nair-12, RT-42-1, RT67- 3 and RT-102-1. Genotypes including 16/103, CM-12, NLSH-1, NLST-3 and RT-90-1 are categorized as ENR. The genotypes viz., Kanchan, TOBIOS-2, RT-36-1, RT-47-1, RT-51-2, and RT-57-1 come under NER category. The NENR was represented by NLST2, NLST-4 and RT-30-1. ER genotypes are to be selected while evolving the varieties for higher potassium use efficiency. | en_US |
