IMPACT OF TEMPERATURE AND RAINFALL DISTRIBUTION OVER 1989-1996 ON THE BIOMETRIC AND STRUCTURAL CHARACTERISTICS AS WELL AS ON THE &ACUTE;JUNO&ACUTE; YELLOW LUPIN YIELDING
Tadeusz Bieniaszewski, Zbigniew Szwejkowski, Gabriel Fordoński
The results of 8-year field experiment helped to analyse the impact of weather conditions on biometric and structural characteristics and on ‘Juno’ yellow lupin yielding. Over 1989-1996-vegetation period there was recorded a large weather conditions variation; the coefficient of temperature variation amounted to 16% and of rainfall –about 49%. The relationship between temperature and rainfall and biometric and structural characteristics as well as seed yielding was defined with statistical regression method. It was observed that temperature had a greater effect in initial and final growth and development phases, while rainfall – over vegetation.
Key words: yellow lupin, temperature, rainfall, biometric and structural characteristics, seed yield.
