International Conference on Reimagining Rainfed Agro-ecosystems: Challenges & Opportunities
during 22-24, December 2022 at ICAR-CRIDA, Hyderabad
Results
The effect of foliar application of DAP at different growth stages of chickpea showedsignificant
effect on grain and stover yield, moisture use efficiency and protein yield. The results revealed
that treatment GRDF along with 2 % DAP foliar spray at 50 per cent pod setting stageshowed
significantly higher grain and stover yield (15.51 and 18.92 q/ha) moisture use efficiency (6.66
kg/ha/mm) and protein yield (291.62 q/ha), respectively over rest of treatments.However,MUE
was at par with GRDF along with 2 % DAP foliar spray at 50 per centflowering stageSimilar
grain and protein yield response of foliar application of different water-soluble fertilizers were
also reported by Takankharet al. (2017), Eliset al. (2020) and Deshmukh et al. (2022) in
chickpea. Treatment GRDF along with 2 per centdiammonium phosphate foliar spray at 50 %
pod setting stagerecorded significantly higher N, P and K uptake (64.75,10.27 and 66.58
kg/ha).Similar nutrient uptake studies were taken byDeshmukh et al. (2022) in chickpea.The
treatment GRDF + 2 % DAP foliar spray at 50 per cent pod setting stage ofchickpea showed
significantly higher available N, P2O5 and K2O (176.38,16.14 and 546.50 kg/ha)respectively over
control treatment.The treatment GRDF along with 2 per cent DAP foliar spray at 50 per cent pod
setting stageof chickpea recorded highest net returns (Rs. 56,920 /- andB: C ratio (2.80) over rest
ofthe treatments.
Conclusion
The application of recommended dose of N and P2O5 (25:50 kg/ha) along with 5 t FYM along
with 2 per cent foliar spray of diammonium phosphate (DAP) is at 50 per cent pod setting stage
was found to be superior for achievinghigher yield and monitory returns of chickpea under
scarcity zone of Maharashtra
