ABSTRACT
This study was conducted to know the effect of Diatomaceous Earth (DE) as source of silicon on chlorophyll content of leaves, yield and disease occurrence in pomegranate Var. Kesar. The highest value for chlorophyll ‘a’ 0.29 milligram/gram was recorded in T9 (RDF + 900 kg/ha of DE) and T7 (RDF + 300 kg/ha of DE), both chlorophyll ‘b’ 0.31 milligram/gram and total chlorophyll content 0.61 milligram/gram was recorded in T7. Least values for chlorophyll ‘a’ 0.19 milligram/gram and total chlorophyll 0.33 milligram/gram noticed in T3 (half of RDF) and for chlorophyll ‘b’ 0.11 milligram/gram recorded in T1 (Absolute control). The treatment T9 (RDF+ 900 kg/ha of DE) recorded higher number of fruits per plant 71.36, yield 21.33 kg per plant, followed by T8 (RDF + 600 kg/ha of DE). Lowest anthracnose disease per cent coverage on fruits 19.06 per cent, least number of anthracnose disease infected fruits 10.20 observed in T9 (RDF + 900 kg/ha of DE) and highest values recorded in T1 (Absolute control) 31.16 per cent, 14.86 infected fruits respectively. Lowest bacterial blight per cent disease coverage on fruits 11.33 per cent, number of fruits infected 12.30, least lesions of bacterial blight per leaf 3.70 observed in T9 (RDF + 900 kg/ha of DE) and highest values recorded in T1 (Absolute control) 26.50 per cent, 14.40 infected fruits and 4.76 lesions per leaf respectively.
Key words: Diatomaceous earth, Chlorophyll, Yield, Anthracnose and Bacterial blight.
