Recent floods in Kerala and its impact on rice yield in Kuttanad – A retrospective analysis

Unprecedented severe floods, which affected Kerala during 2018 and 2019 submerged Kuttanad almost completely and the effects of these severe floods to following rice crop were studied. In these severe floods, the following rice crop puncha reflected a marked increase in yield mainly due to increase in soil fertility and less incidence of pests and diseases. In view of total rice production in the kuttanad region, severe floods have even a positive effect on rice production as the ground water table rose to facilitate water to the rabi crop. It was observed that there has been a notable variation in minimum temperature and relative humidity. All these factors contributed significantly to increase in rice yield. Floods are not always disastrous and can sometimes be advantageous as indicated by the post flood rice yields in kuttanad

A wide gap exists between potential and actual yields of mustard in India. Mustard is highly sensitive to weather variables and thus attempts need to be focused on determining the most yield limiting weather parameter so as to bridge the yield gap. To accomplish this task, mustard (c.v. RH-30) yields recorded for 26 rabi seasons (1984-85 to 2009-10) at Hisar, Haryana state were related with weather parameters during crop period. Maximum temperature during 1-6 week after sowing (WAS), minimum temperature during 1-5 WAS and again 16-20 WAS were found to influence mustard yields significantly. The mustard yields were less than 2000 kg ha-1 when maximum temperature was less than 30°C during 1-6 WAS and minimum temperature was less than 12°C during 1-5 WAS. Higher yields (2400 to 3000 kg ha-1) was obtained when minimum temperature during 16-20 WAS was less than 6°C.
