Abstract
The study revealed that treatment T7 = NPK + Zinc (130 + 65 + 35 + 2 kg ha-1) recorded maximum plant population (7.6 m-2), plant height (193.3 cm), stem girth (6.4 cm), cobs plant-1 (2.2), cob length (21.3 cm), cob weight (163.0 g), seed weight cob- 1 (70.6 g), seed index (212.3 g), biological yield (13333 kg ha-1) and grain yield (3433.33 kg ha-1) followed by plant population (6.6 m-2), plant height (179.3 cm), stem girth (6.0 cm) cobs plant-1 (1.9), cob length (17.3 cm), cob weight (149.6 g), seed weight cob-1 (65.0 g) seed index (193.3 g) biological yield (12833 kg ha-1) and grain yield (3000.0 kg ha-1) observed in treatment T8 = NPK + Boron (140 + 70 + 40 + 2 kg ha-1). Application of treatment T2 = NPK + Boron (100 + 50 + 25 + 2 kg ha-1), treatment T3 = NPK + Zinc (100 + 50 + 25 + 2 kg ha-1), treatment T4 = NPK + Boron (120 + 60 + 30 + 2 kg ha-1), treatment T5 = NPK + Zinc (120 + 60 + 30 + 2 kg ha-1), treatment T6 = NPK + Boron (130 + 65 + 35 + 2 kg ha-1) and treatment T9 = NPK + Zinc (140 + 70 +40 + 2 kg ha-1) were ranked in each related ranking 3rd, 4th, 5th, 6th, 7th and 8th almost all traits studied. Whereas, the minimum plant population (3.7 m-2), plant height (143.7 cm), stem girth (3.3 cm), cobs plant-1 (1.0), cob length (10.0 cm), cob weight (110.0 g), seed weight cob-1 (42.6 g), seed index (175.6 g), biological yield (11683 kg ha-1) and grain yield (2236.7 kg ha-1) was observed under treatment T1 = Control (un-treated) where no any fertilizer was applied. The results were statistically significant at (P<0.05) as affected by different applications of macro and micro nutrients on the growth and yield of maize. It is concluded that the crop was fertilized with NPK + Zinc (130 + 65 + 35 + 2 kg ha-1) macro and micro nutreitns gave best results for getting higher yield of maize crop as compared to other applications of the macro and micro nutrients.
