Abstract
Aim:
This experiment was conducted to find out appropriate technical intervention
for integrated management of nitrogen and iron chlorosis in irrigated
groundnut in arid regions.
Methodology: Two levels of farmyard manure, five levels of
nitrogen and three levels of iron spray were applied in irrigated groundnut.
Chlorophyll content, active iron content, periodic dry matter accumulation,
oil content and yield, protein content and nutrient uptake by groundnut were
studied. Most effective level of farmyard manure, nitrogen application and
iron spray were identified for optimum management of the resources.?
Results:
The results showed that application of farmyard manure @ 15 t ha-1,
nitrogen @ 60 kg ha-1 in two or three splits and foliar spray of
FeSO4 @ 1.0 % in combination with citric acid @ 0.1% was found
supportive in correcting iron chlorosis by increasing chlorophyll and active
iron content, improving oil content and yield, protein content and nutrient
uptake and ultimately enhancing net return by groundnut under irrigated
conditions.
Interpretation: Farmyard manure, higher dose of nitrogen
in split application and foliar spray of iron is helpful in correcting iron
chlorosis, improving growth, quality and nutrient uptake and increasing
income of groundnut growers under irrigated condition in arid regions.
