Abstract

Tissue NUTRIENT STATUS of high yielding plant populations can be a reference norm for evaluation of growth and achievement of optimal yield. Compositional REFERENCE NORMS derived from generic models are important. Yield data of 382 SUGAR BEET fields was analyzed and, using mathematical approach, cumulative variance ratio function[Fic()], and chi-squared distribution function, the low (n1= 259) and high (n2= 123) yielding subpopulations were separated from each other. Cutoff yield was obtained at 53.980 t.ha-1. Critical chi-squared value was found to be 7.3 and was confirmed by using data of leaf samples from 38 fields and Cate-Nelson statistical procedure. Preliminary CND norms of different elements were found as follows: V*N=3.442±0.145, V*P=0.765±0.139,V*K =3.197±0.187, V*Zn=-3.691±0.306, V*Fe=-3.317±0.321, V*Cu=-4.377±0.233, V*B =-3.487±0.293, V*S=1.359±0.283, V*Rd=6.589±0.076. Later, nutrient sufficiency range and critical intervals norms and nutrient indexes for CND were determined using analysis results of 38 SUGAR BEET tissue samples. Satisfactory results were obtained when data of many fertilizer trials were investigated to arrive at preliminary validation of norms and indexes. These norms, indexes, nutrient sufficiency ranges, and critical intervals can be used for prediction of growth, yield, and nutrition disorders of SUGAR BEET.
