ABSTRACT
Investigation entitled “Integrated nutrient management under ginger-cauliflower cropping sequence in
North-Western Himalayas” was conducted during 2015-16, 2016-17 and 2018-19 at the Experimental
Farm of Dept. of SSWM, UHF Nauni, Solan. ‘Himgiri’ variety of ginger and cauliflower var. ‘PSB K–1’
were used with 14 treatment combinations replicated thrice in Randomized Block Design. The fourteen
treatments were as follows: T1 (Absolute control), T2 (100% RDF and FYM + grass mulch), T3 (100% RDF
and FYM + pine mulch), T4 (75% RDF + 25% N through FYM on equivalent basis + grass mulch), T5 (75%
RDF + 25% N through FYM on equivalent basis + pine mulch), T6 (75% RDF + 25% N through VC on
equivalent basis + grass mulch), T7 (75% RDF + 25% N through VC on equivalent basis + pine mulch), T8
(50% RDF + 50% N through FYM on equivalent basis + grass mulch), T9 (50% RDF + 50% N through
FYM on equivalent basis + pine mulch), T10 (50% RDF + 50% N through VC on equivalent basis + grass
mulch), T11 (50% RDF + 50% N through VC on equivalent basis + pine mulch), T12 (50% RDF + 25% N
through FYM on equivalent basis and 25% N through VC on equivalent basis + grass mulch), T13 (50%
RDF + 25% N through FYM on equivalent basis and 25% N through VC on equivalent basis + pine mulch)
and T14 (100% NPK through FYM + No mulch). Amongst mulches grass mulch recorded, higher moisture
contents than pine mulch and unmulched control in both the crops. In ginger, pine mulch was more effective
in lowering the maximum temperature, while in cauliflower; grass mulch was more favorable. Application
of 100 per cent recommended dose of fertilizers and FYM (T2 and T3) was found to be most effective in
increasing soil nutrient status, while application of 100 per cent NPK through FYM (T14) was found to be
superior with respect to improving SOC, soil physical and microbiological properties. Application of 75%
RDF + 25% N on equivalent basis through VC (T6 and T7) recorded superior growth and quality
characteristics in both the crops. In ginger, treatment T7 (75% RDF + 25% N through VC on equivalent
basis + pine mulch) registered 80.2 and 7.0 per cent higher rhizome yield over absolute control and RDF,
respectively, while, in cauliflower, treatment T6 (75% RDF + 25% N through VC on equivalent basis +
grass mulch) recorded 51.5 and 6.5 per cent higher curd yield over absolute control and RDF, respectively.
Different nutrient management treatments influenced plant nutrient contents to a varying degree in both the
crops. In ginger, NUE (48.6%), AE (64.6 kg kg-1), NHI (70.8%), KHI (72.1%) and HI (71.4%) were highest
under T7. Treatment T6 registered higher NUE (49.5%), AE (62.2 kg kg-1), PHI (56.6%), KHI (51.6%) and
HI (48.9%) in cauliflower. Highest net returns in ginger (Rs. 6.21 lakhs ha-1) and cauliflower (Rs. 3.57 lakhs
ha-1) were obtained with application of 75% RDF + 25% N on equivalent basis thorough FYM. Hence, it
can be concluded that dose of 75% RDF + 25% recommended N through FYM and VC along with organic
mulching could be recommended to the farmers as a cost effective nutrient module for getting higher yields
of superior quality under ginger-cauliflower cropping sequence on sustainable basis and for improving soil
health on a long term basis.
