Here I enclosed a mungbean field condition (Picture) after heavy rainfall. Mungbean crop is highly susceptible to water logging, So please suggest proper mangement to reduce adverse effects of water logging
Thank you
Regards
Kuldeep Singh
1. Water should not stagnate for more than 7-8 hours. But i could guess the soil type which appears will absorb.
2. Hope you might have drained stagnated water.
3. Your field is not properly leveled.
4. In future broad bed and furrow method should be used for kharif pulses and soyabean
The prevention of your condition is possible with a more profound drainage ditch and a greater drain angle and provision of greater catchment.
The cultivated area on a higher raised bed.
In general, grain legumes are sensitive to waterlogging and partial submergence. During rainy season, it should be grown following raised bed or ridge and furrow method. The field should have proper drainage system. The waterlogging tolerance of mungbean is stage-specific, that is, seedling stage is more sensitive than adult plant stage. Excess moisture delays flowering and maturity.
Suggested raised bed planiting system. Mullti rows on the raised part.
Dear Kuldeep Singh the photograph is clearly stated that you have given irrigation as surrounding picture is not wetted. Though legume is very sensitive to waterlogging but if it persist after sowing then drainage is only option to drained out water. Even pumping out of extra water also a part of drainage. Don't worried mungbean has capasity to overcome this problem at later stage. Regards
Uma Nath Shukla Sir, Thank you, Yes I had pump out extra water that time, now my crop is healthy
So the land preparation should be carefully done. The soil must be ploughed to a depth of 30-40 cm and worked to very fine tilth.
Well drained soils are usually used .
After that the planting density also must be considered
a) Dibble seed on raised bed as shown in the diagram
b) Spacing recommended for Bush bean - 50 × 10 cm, so for mung bean as well we can go for the same procedure as bush beans . also, seed rate for Bush beans is 75 kg/ha Kuldeep Singh .also Earthing up after 1 week of planting is also considered as a proper management practice for mung beans. here in this above picture the land preparation was not carried well

Mung bean cannot withstand waterlogging, particularly during the early stages of growth. Production of the crop is affected by unexpected and increasingly frequent extreme precipitation events, and in transient soil waterlogging and reduced soil redox potential, delayed or even prevented germination, decreased seedling establishment, and affected shoot and root development and large reduction in root nodule number and dry matter indicated that waterlogging might have reduced nitrogen fixation and level of endogenous plant hormones, which increase dropping of flowers and/or the loss of pod setting.
