SUMMARY
A field experiment was conducted during kharif season of 2018, 2019 and 2020 to study the effect of split application of nitrogen to dual purpose kharif sorghum at Centre for Millets, Sardarkrushinagar Dantiwada Agricultural University, Deesa. The experiment was carried out in randomized block design with three replication comprising thirteen treatments viz., T1 [50 % basal + 50 % split and one split (30 DAS), T2 [50 % basal +50 % split and two split (20 and 40 DAS)], T3 [50 % basal + 50 % split and three split (20, 40 and 60 DAS)], T4 [50 % basal + 50 % split and four split (20, 40, 60 and 80 DAS)], T5 [25 % basal + 75 % split and one split (30 DAS), T6 [25 % basal + 75 % split and two split (20 and 40 DAS)], T7 [25 % basal + 75 % split and three split (20, 40 and 60 DAS)], T8 [25 % basal + 75 % split and four split (20, 40, 60 and 80 DAS)], T9 [No basal + 100 % split and one split (30 DAS), T10 [No basal +100 % split and two split (20 and 40 DAS)], T11 [No basal + 100 % split and three split (20, 40 and 60 DAS)], T12 [No basal + 100 % split and four split (20, 40, 60 and 80 DAS)] and T13 (100 % RDN) in which 75 % recommended dose of nitrogen was applied in treatment T1 to T12 while in treatment T13 full dose of nitrogen was applied as a basal. Sorghum under rain-fed environment of North Gujarat with 25 % N (15 kg) as basal and remaining 75 % N (45 kg) in three equal splits at 20, 40 and 60 DAS in addition to recommended dose of phosphorus (40 kg/ha) as basal for obtaining significantly higher number of leaves, leaf length, leaf width, ear head length, grain yield, dry fodder yield and net return with saving of 25 % N.
