ABSTRACT
A study was conducted in 2010 and 2011 to study the effect of drip fertigation and season on resultant seed quality in kharif and summer crops of pigeonpea (Cajanus cajan L.) cv. VBN 3. Data were collected on 100 seed weight, germination, seedling length, dry matter production and vigour index in the pigeonpea resultant seeds evaluated in both season. Significant drip fertigation and seasonal effects on seed quality attributes in the resultant seeds of pigeonpea were obtained. In general, kharif season crop recorded higher seed quality than the summer season crop. The results revealed that fertigation exhibited significant effect on seed quality parameters. Among the treatments, T4, T5, T6, T7, T8, T9, T10, T11 and T12 resultant seed quality were recorded higher physiological seed quality as compared to T1, T2, T3 and control in both season. Seed weight, seed germination, seedling length, dry matter production and vigour index could be taken as parameters for improving seed quality potential in kharif season.
Key Words: Cajanus cajan L, drip fertigation, kharif, summer, resultant seed, seed quality attribute.
