Abstract
A field experiment was conducted at Agricultural College and Research
Institute, Killikulam (TNAU) during Puratassipattam (Sep–Dec., 2017) to
study the effect of crop geometry, fertilizer levels and foliar nutrition on the
yield attributes, yield and economics of irrigated blackgram. The experiment
was laid out in randomized block design and replicated thrice with twelve
treatments. The treatment consists of two spacings, two fertilizer levels
and spraying of foliar nutrients and growth regulators. The results revealed
that plant spacing of 30 × 15 cm with 100 % RDF coupled with foliar spray
of TNAU Pulse Wonder @ 1.125% at 50 % flowering recorded higher yield
attributes, yield and highest profit. The seed yield increases with 29 % over
the adoption of crop spacing of 30 × 10 cm with 100 % RDF without any
foliar nutrition.
Key words : Crop geometry, Fertilizer levels, Foliar nutrition, Yield attributes, Yield,Economics
