Abstract:
A field experiment was conducted during Rabi season of 2020-21 at SHUATS, Prayagraj to study the effect of applied Neem coated urea over normal urea with respect to various doses and time of application on Barley (Hordeum vulgare L.). The experiment was laid out in Randomized Block Design with ten treatments which were replicated thrice. Application of 125% RDN as neem coated urea (NCU) at 50% basal followed by 25% at 25 DAS and 25% at 45 DAS recorded significantly higher plant height (86.11 cm) and plant dry weight (20.35 g/plant). 125% RDN as NCU (33.33% Basal + 33.33% at 25DAS + 33.33% at 45 DAS) resulted in significantly higher number of tillers/m2 (424.00) as well as yield and yield attributes except for test weight i.e., spike length cm), Grain yield (5.43 t/ha), Straw yield (8.13 kg/ha) and Harvest Index (40.04%). This might be due to uniform availability of nitrogen at later growth stages because of higher and even splits during time of tillering and maximum growth due to slower release of nitrogen as a result of using neem coated urea. Significantly higher test weight (53.67 g) was recorded with 100% RDN applied as NCU (33.33% Basal + 33.33% at 25DAS + 33.33% at 45 DAS). Agronomically, application of neem coated urea resulted in 23.6% higher grain yield than normal urea.
