Growth, Yield and Water Use Efficiency of Sweet Sorghum [Sorghum bicolor (L.) Moench] Affected by Drip Irrigation and Nitrogen Levels through Fertigation

An experiment entitled “Growth, yield and water use efficiency of sweet sorghum [Sorghum bicolor (L.) Moench] affected by drip irrigation nitrogen levels through fertigation” was carried out on clayey slightly alkaline soil during rabi season 2019-20 2020-21 at the Instructional Farm, Department Agronomy, College Agriculture, Junagadh Agricultural University, Junagadh. The laid in split plot design with four replications. There were nine treatment combinations. main treatments viz; (I1) 0.6 PEF, (I2) 0.8 PEF (I3) 1.0 PEF; sub consist three fertigation (N1) 75% RDN fertigation, (N2) 100% (N3) 125% (RDF for is 90-40-40 N, P2O5 K2O kg ha-1). results revealed that scheduling enhance consumptive which ultimately resulted higher grain fodder yields sorghum. indicated significantly increased efficiency, eventually recorded Based two years experimentation, it can be concluded getting yields, should applied common surface each 50 mm depth followed (operating pressure: 1.2 cm-2 lateral spacing: 120 cm) alternate day crop fertilized which, 50% as basal remaining five equal splits 10 days interval started from 35 DAS.
