Influence of spacing and organics on plant nutrient uptake of black nightshade (Solanum nigrum)..

Abstract


Sivakumar V. and Ponnusami V.

Investigations were carried out at the Horticultural College and Research Institute to study the effect of spacing and bio-stimulants on the plant nutrient uptake of Solanum nigrum. The experiments were laid out in split plot design with three replications. The treatments consisted of four levels of spacing (M1 – 30 × 30 cm, M2 – 45 × 45 cm, M3 – 60 × 30 cm and M4 – 60 × 45 cm) and nine bio-stimulants/organics (S1– Recommended dose of fertilizer (RDF), S2 – control, S3 – panchagavya 2%, S4 – panchagavya 3%, S5 – moringa leaf extract 2%, S6 – moringa leaf extract 4%, S7 – humic acid, S8 – cytozyme 1% and S9 – vermicompost). Observations on nutrient uptake found that, the treatment closer spacing + RDF (M1S1) registered higher nitrogen uptake (223.83 kg ha-1 ) and phosphorous uptake (22.02 kg ha-1 ) followed by closer spacing + panchagavya 3% spray (M1S4) (202.64 kg ha-1 ) (Nitrogen uptake - 202.64 kg ha-1 and Phosphorous uptake -20.03 kg ha-1 ). Regarding the potassium uptake the treatment wider spacing + RDF (M4S1) combination recorded the highest K uptake (252.83 kg ha-1 ) followed by the treatment wider spacing + humic acid combination (M4S7) (227.14 kg ha-1 ).
