Abstract
A field experiment was conducted to study the response of chilli to irrigation and
FYM levels under Vertisols at Water Management Research Centre, Belvatagi during kharif
2011-12. The irrigation levels were 0.3, 0.5 and 0.7 IW/CPE ratios and the FYM levels were
zero FYM, 10, 15, 20 and 25 t ha-1 along with RDF (150:75:75 N, P2O5 and K2O kg ha-1)
comprising fifteen treatment combinations, replicated thrice with split plot design.
Significantly higher chilli yield was observed with irrigation at 0.5 IW/CPE (1794.2 kg ha-1)
ratio. Application of FYM @ 20 t ha-1 + RDF significantly increased the yield of chilli
(1834.7 kg ha-1) compared to lower FYM levels. Similarly, significant differences in growth
parameters such as leaf area, LAI and total dry matter production were also noticed in the
same set of treatment. Irrigation @ 0.5 IW/CPE ratio recorded significantly higher uptake of
NPK at harvest. Among FYM levels application of FYM @ 20 t ha-1 + RDF recorded higher
uptake of these nutrients at harvest than the lower levels of FYM. Irrigation at 0.7 IW/CPE
ratio and FYM @ 25 t ha-1 +RDF recorded significantly higher available soil NPK. The
quality parameters of dry chilli did not change significantly with irrigation levels. However,
higher ascorbic acid and oleoresin content was observed with application of FYM @ 20 t ha-1
+ RDF. Consumptive use of water was higher with irrigation at 0.7 IW/CPE ratio and higher
water use efficiency was with irrigation at 0.3 IW/CPE ratio. Irrigation level of 0.5 IW/CPE
ratio recorded higher gross income (` 212320 ha-1), net income (` 180657 ha-1) and B: C ratio
(5.45). Among FYM levels application of FYM @ 20 t ha-1 + RDF recorded higher gross
income (` 218767 ha-1), net income (` 183971 ha-1) and B:C ratio (5.1). The interaction effect
between irrigation and FYM levels were non-significant for yield, yield attributing
characters, quality parameters and monetary returns.
