ABSTRACT

Field experiments were conducted during summer (Feb-June) and rabi (Aug-Dec)
seasons of 2004 to study the effect of integrated nutrient management practices on
yield characters, economic yield, economics and nutrient uptake of castor (Ricinus
communis) under irrigated conditions. Application of FYM @ 12.5 t ha-1+
Azospirillum + phosphobacteria recorded significantly maximum length of primary
spike, more number of spikes plant-1, capsules spike-1, seed and oil yield and nutrient
uptake as compared to pressmud @ 2 t ha-1+ Azospirillum + phosphobacteria and
sugarcane biocompost @ 1 t ha-1. Similarly the maximum length of primary spike,
more number of spikes plant-1, capsules spike-1, seed and oil yield and nutrient uptake
of castor were recorded with application of 75 % RDF NPK + ZnSO4 @ 12.5 kg ha-1
as basal + ZnSO4 0.25% foliar spray twice at 30 and 45 DAS as compared to other
inorganic nutrients. The similar organic and inorganic nutrient treatment proved to
be more economical in view of its higher net returns and benefit: cost ratio in both
the seasons, summer and rabi.
