Pigeonpea (Cajanus cajan L.) growth and yield with varying spacing and fertilizer

Abstract

A field experiment was conducted during kharif season of 2020 at the research farm of Amar Singh College Lakhaoti. Treatment consisted
of 3 Row spacing (30, 60 and 90 cm) and 3 levels of DAP application (control, 100 and 200 kg/ha). Results showed that treatment of
30 cm row spacing produced at par plant height compared to 60 cm row spacing. Treatment of 100 kg DAP per hectare produced
significantly plant height as compared to 200 kg DAP per hectare. The same trend was observed for a number of branches, leaves
and dry matter accumulation. Treatment of 60 cm row spacing was found to be significantly superior over 30 cm raw spacing for yield
and yield attributes treatment of 30 cm raw spacing recorded significantly higher protein content as compared to 60 cm raw spacing,
whereas treatment of 100 kg DAP per hectare was found significantly superior over control and 200 kg DAP per hectare for various
growth parameters, yield attributes and yield.
