Abstract
:The study was a field experiment conducted in the Experimental Farm of the School of Agriculture on the campus of Lovely Professional University in Punjab, at latitudes of 31°24' N and 75°69' E. Analyzing the effects of adding nitrogen to both organic and inorganic fertilizer solutions on maize growth, yield, nutrient absorption, and economics in India during the kharif season of 2022. At the experimental site, the soil texture is coarse loamy Typic Haplustept soil. The trial had sixteen treatments, a randomized block design, and was triple repeated. Following the recommended fertilizer schedule of 50:24:12 N, P2O5, and K2O kg ha-1. To supply the nutrients N, P, and K, respectively, fertilizers containing urea (46% N), single super phosphate (16% P2O5), and muriate of potash (60% K2O) were used. The hybrid PAU variety of maize known as PMH-13, which was utilized in the tests, was the subject of this study and analysis. Both potassium and phosphorus are supplied completely by basal application. Nitrogen was administered at the appropriate amount in a basic manner. Net plot area was used to compute crop yields. Crop observations were conducted at the 20 DAS, 40 DAS, 60 DAS, 80 DAS, and harvest stages. For the purpose of recording biometric observations, samples from each plot were randomly selected. After spraying Nanourea to plant leaves, the plants grow 40, 60, 80 DAS taller and produce yield. After harvest, maizecobs with ears measured 22.9 cm, with 100% RDF+Nanourea treatments having the highest measurement and 75%RDF (3 Application Timings) treatments having the lowest measurement. After 10 days of sowing, the treatments with 100% RDF+ FYM 5t ha-1 had 81 plants the most. Fresh weight of seven maize plants is 3215 gm greatest in 100% RDF+FYM 5t ha-1 treatments and 2167 gm lowest in 100% RDF+Nano urea treatments. Maizecobs length without ear is 16.4 cm lowest in Absolute control treatments and 18.9 cm highest in 100% RDF (2 Application timings) treatments, Seven maize plants treated with 100% RDF (2 application timings) had the maximum dry weight of 804 gm, whereas seven plants treated with 75% RDF had the lowest dry weight of 518 gm among all the treatments.
