A 5-year field trial to assess the impact of microsprinkler irrigation and nutrition on vanilla grown
as intercrop in arecanut plantation was conducted on a laterite soil. Pooled analysis indicated that
microsprinkler irrigation at 1.0 Epan resulted in significantly higher green bean yield (842 kg ha−1) than
0.75 Epan (579 kg ha−1). Organic manure application in the form of vermicompost (720 kg ha−1) and FYM
(768 kg ha−1) and recommended NPK (718 kg ha−1) produced green bean yield at par with recycling of
gliricidia prunings (625 kg ha−1). Irrigation at 1.0 Epan proved superior by registering maximum benefit:
cost (B:C) ratio of 2.25 compared to 1.62 at 0.75 Epan. The highest B:C ratio was obtained with
recommended NPK (2.27) followed by recycling of gliricidia prunings (2.10), vermicompost (1.87), vermicompost
+ arecanut husk mulching (1.80) and FYM (1.64). The soil pH increased by 0.4 units in 2008
compared with the pre-experimental soil pH of 5.6 in 2004. Nutrition alone and in combination with
irrigation had significant impact on soil pH. Organic manure application increased the soil pH (6.1–6.2)
significantly over recommended NPK (5.6) at the end of experiment in 2008. Significant variation in soil
organic carbon (SOC) was noticed due to different nutrition treatments. Application of vermicompost
and FYM significantly increased the SOC content by 38–54% in 2008 over initial levels in 2004. Bray’s P
availability was influenced by nutrition and its interaction with irrigation. Application of FYM continuously
for 4 years has resulted in significant increase in Bray’s P content (41.3mgkg−1) compared to other
nutrition treatments (9.4–17.2mgkg−1). Irrigation equivalent to 0.75 Epan (223mgkg−1) increased the
K availability significantly over 1.0 Epan (172mgkg−1). The K availability was significantly higher in recommended
NPK (416mgkg−1) than in other organic treatments (98–223mgkg−1) at 0–30cm soil depth.
Overall, vanilla responded well to irrigation and nutrition in arecanut-based cropping system with a
better economic output and improved soil fertility.
