Abstract
A field experiment was conducted at Main Maize Research Station farm, Anand Agricultural University, Godhra, Gujarat during consecutive two kharif seasons of 2022 and 2023 to study the effect of nutrient omission on growth and yield of maize (Zea mays L.).The experiment was laid out in Randomized Block Design with 3 replications.The fourteen treatments on nutrient omission viz., control (T 1 ), 160 kg N ha -1 (T 2 ), 20 kg P 2 O 5 kg ha -1 (T 3 ), N 160 P 20 kg ha -1 (RDF) (T 4 ), N 160 P 20 K 60 kg ha -1 (T 5 ), N 160 P 20 S 20 kg ha - 1 (T 6 ), N 160 P 20 Zn 5 kg ha -1 (T 7 ), N 160 P 20 Fe 10 kg ha -1 (T 8 ), N 160 P 20 K 60 S 20 kg ha -1 (T 9 ), N 160 P 20 K 60 Zn 5 kg ha - 1 (T 10 ), N 160 P 20 K 60 Fe 10 kg ha -1 (T 11 ), N 160 P 20 K 60 S 20 Zn 5 kg ha -1 (T 12 ), N 160 P 20 K 60 S 20 Fe 10 kg ha -1 (T 13 ) and N 160 P 20 K 60 S 20 Zn 5 Fe 10 kg ha -1 (T 14 ) were studied.The maize variety GAWMH 2 was grown for two consecutive kharif seasons.The treatment N 160 P 20 K 60 S 20 Zn 5 Fe 10 kg ha -1 (T 14 ) resulted in higher plant height at 60 DAS (203 cm) and at harvest (217 cm), cob length (17.13 cm), cob girth (13.82 cm), seed index (24.67g), grain yield (5231 kg ha -1 ) and stover yield (9728 kg ha -1 ).Further, the treatments with omission of major nutrients, namely T 2 :N 160 P 0 (-P) and T 3 : N 0 P 20 (-N) were significantly inferior in the performance of all growth and yield attributes of maize as compared to Recommended Dose of Fertilizer (T 4 ).Similarly the treatments with omission of micronutrients, namely T 12 (-Fe) and T 13 (-Zn) were also significantly lower in growth and yield attributes compared to all nutrient treatment T 14 (N 160 P 20 K 60 S 20 Zn 5 Fe 10 kg ha -1 ) .The grain and stover yield increased 21.69 and 27.29% in T 14 treatment as compared to RDF (NP).The lowest grain and stover yield (3316 and 5434 kg ha -1 ) were recorded in control treatment (T 1 ).The grain and stover yield increased with the stepwise addition of different nutrients in combination with nitrogen and phosphorus over application of RDF (NP only) with the increasing trend is as followed: NP <NP+Fe <NP+Zn <NP+S <NP+K <NPK+Fe <NPK+Zn <NPK+S <NPKS+Fe <NPKS+Zn <NPKSZn+Fe.The findings indicated that adequate application of the four primary nutrients (nitrogen, phosphorus, potassium and sulphur) along with two micronutrients (zinc and iron) was essential for attaining optimum growth and yield of maize.
