Abstract

The experiments were conducted during Kharif 2005 and 2006 at Students’ Instructional Farm, C.S. Azad University of Agriculture & Technology, Kanpur. The results revealed that different fertilizer treatments besides effecting significant increase in yield also scaled up the nutritional quality traits of maize crop. STR 150% + S + Zn + FYM 5 t gave the highest protein, oil and starch contents but the amylose and amylopectin fractions of starch were not significantly affected by different treatments. The highest values of harvest of protein (627 kg ha−1), oil (481. 4 kg ha−1) and starch (4484 kg ha−1) were obtained in the treatments STR 150% + S + Zn + FYM 5 t. Out of the total of 4484 kg ha−1, of starch 1800 kg ha−1 was amylose and the rest was amylopectin on the basis of two year field study.
