RESPONSE OF SOME SPRING WHEAT CULTIVARS TO DIVERSE MINERAL NPK FERTILIZATION

摘要: Mineral fertilization is one of the most important components proper cultivation technology spring wheat. It actually determines quantity and quality grain yield. In 2011-2013 a strict field experiment was carried out which aimed to determine response chosen wheat cultivars two NPK levels. research hypothesis it assumed that varied rates will modify canopy structure, state plant nutrition Two levels were used: 80 N; 43.6 P 83 K kg·ha -1 (level I) 120 65.4 124.5 II). The tested were: Hewilla, Monsun, Nawra, Ostka Smolicka, Waluta, Zadra, Żura. higher rate mineral in comparison with lower resulted significant increase SPAD LAI indices values, whereas did not MTA index. number ears per 1 m 2 on treatment level as compared lower. obtained difference average amounted 26 no.·m . grains ear TGW modified by factor. Spring gave highest yields 2012 lowest 2013. After use level, mean yield 5.83 Mg·ha significantly than (4.89 ).
