Abstract
A field experiment was conducted at College Agronomy farm, B.A. College of Agriculture, Anand Agricultural University, Anand to study the influence of levels and time of application of nitrogen on growth, yield and nitrogen uptake by Pearl millet (Pennisetum glaucum L.) during summer. With increasing levels of nitrogen up to 120 kg N ha-1, the leaf area plant-1, dry matter yield plant-1, grain and stover yield, nitrogen content and uptake by grains were also increased. Application of N as 50% basal + 25% top dressing at 30 DAS + 25% foliar spray at 45 DAS (S3) showed an increase in leaf area plant-1, dry matter yield plant-1 as well as grains and stover yield as compared to other treatments except 50% basal +25% top dressing at 30 DAS +25% foliar spray at 60 DAS (S4). Application of N as 50% basal +25% top dressing at 30 DAS +25% foliar spray at 60 DAS (S4) recorded significantly higher nitrogen uptake by grains and stover than other treatments except 50% basal + 25% top dressing at 30 DAS + 25% foliar spray at 45 DAS (S3). Nitrogen content in grains and stover were increased in the treatment except the treatment 50% basal + 25% foliar spray at 30 DAS + 25% foliar spray at 60 DAS (S5) as compared to other treatments of 50% basal + 25% top dressing at 30 DAS + 25% foliar spray at 45 DAS (S3) and 50% basal +25% top dressing at 30 DAS +25% foliar spray at 60 DAS (S4). The interaction effect revealed that N@ 120 ha-1 applied as 50% basal +25% top dressing at 30 DAS +25% foliar spray at 60 DAS (N3S4) recorded maximum grain yield and nitrogen uptake by grains as compared to rest of the treatment combinations, while the highest nitrogen content of grain was recorded under treatment combination 120 kg N ha-1 applied as 50% basal + 25% top dressing at 30 DAS + 25% foliar spray at 45 DAS (N3S3), which was on par with N@ 120 kg ha-1 as applied as 50% basal +25% top dressing at 30 DAS +25% foliar spray at 60 DAS (N3S4).
