Abstract:The experiment was conducted during
Kharif season of the year 2022-23 the field Experiment was conducted at crop research centre farm, Department of agronomy, school of agriculture, ITM University Gwalior, Madhya Pradesh to study the effect of foliar application of nutrients at different stage of crop on growth and yield attributes of soybean under randomized complete block design (RCBD) with three replications. This study aimed to evaluate the performance of ten combination of foliar application of nutrients on soybean crop. The Treatment was T
1: Control, T
2: RDF, T
3: RDF+ Urea @ 2% Spray at 45 DAS, T
4: RDF+ DAP @ 2% Spray at 45 DAS, T
5: RDF+ SOP @ 2% Spray at 45 DAS, T
6: RDF+ 19:19:1 @ 2% Spray at 45 DAS, T
7: RDF+ 13:00:45 @ 2% Spray at 45 DAS, T
8: RDF+ 12:61:00 @ 1% Spray at 45 DAS, T9: RDF + 00:52:34 @ 1% Spray at 45 DAS and T
10: RDF + 19:19:19 @ 1% Spray at 30 DAS+ 13:00:45 @ 1% Spray at 45 DAS.
The experimental field’s terrain is well leveled and consistent. The soil texture of the experimental field was sandy loam soil, medium in available nitrogen (163 kg ha-1), medium in available phosphorus (19.40 kg ha-1), medium to high in available potassium (270.80 kg ha-1) and neutral in pH (6.9 pH). The environmental conditions were moderately congenial for normal growth and maturity of soybean crop. The foliar application of fertilizer 19:19:19 @ 1.0% at 30 DAS +13:00:45 @ 1.0% at 45 DAS recorded significantly higher growth, yield attributes and yield of soybean as compare to other treatments and its followed by 19:19:19 @ 2% at 45 DAS which was at par with application 13:00:45 @ 2% at 45 DAS, 12:61: 00 @ 1% at 45 DAS and 00:52:34 @ 1% at 45 DAS.
