Abstract:
A field experiment was conducted at All India Coordinated Research Project on Sorghum (AICRP on Sorghum) centre, Surat, Gujarat in a deep clay soil during kharif 2020 to study the evaluation of pre-released kharif grain sorghum genotypes to different fertility levels under south Gujarat Condition. Soil of experimental field was deep clay in nature. It was medium in available nitrogen (250 kg/ha), high in available phosphorus (51 kg/ha) and available potassium (251 kg/ha). The experiment consisted of 32 treatment combinations comprising eight genotypes (three hybrids: SPH 1888, SPH 1914, SPH 1912 and two varieties: SPV 2568, SPV 2569) along with three checks (two hybrids: CSH 25, CSH 30 and one variety: CSV 20) were evaluated for their grain production potential across three fertility levels (50% RDF, 100% RDF and 150% RDF along with control). The experiment was laid out in Split Plot Design with 2 replications at Surat. Results showed that among different fertility levels, the differences in grain yield and stover yield was found significant. The highest grain yield (4160.1 kg/ha) and stover yield (13057.2 kg/ha) was recorded by F4: 150% RDF (120:60:60 NPK kg/ha), which was followed with F3: 100% RDF (80:40:40 NPK kg/ha) (3467.8 kg/ha grain yield and 10886.8 kg/ha stover yield). Among different genotypes G6: CSH 25 recorded significantly highest grain and stover yield (4080.4 and 12063.4 kg/ha) and which was followed by G3: SPH 1912 (3562.0 kg/ha grain yield). While in case of stover yield, it was being remained at par with G4: SPV 2568. (11389.9 kg/ha).
