Abstract
The experiment was conducted during the period from 11 December, 2012 to 30 March 2013 to study the effect of supplementary nitrogen, irrigation and hormones on flower droppings, growth and reproductive behaviour of chickpea. Statistically significant variation was recorded for different growth and reproductive parameters. Results showed that BARI chola 9 gave the highest plant height, number of branches plant -1 , dry matter content plant -1 , pod remaining, pod length, seed yield and the lowest flower dropping, pod dropping, total dropping. Among the supplemental treatments, the highest plant height, number of branches plant -1 , dry matter content plant -1 , pod remaining, pod length, seed yield and the lowest flower dropping, pod dropping, total dropping were found from supplemental irrigation + aqueous N before flowering. In case of treatment combination, the highest plant height (39.31 cm), number of branches plant -1 (6.53), dry matter content plant -1 (7.02 g), pod remaining (39.67 %), pod length (1.96 cm), seed yield (1.94 t ha -1 ) and the lowest flower dropping (57.27 %), pod dropping (3.07 %), total dropping (60.33 %) was recorded from BARI chola 9 with supplemental irrigation + aqueous N before flowering.

Summary
Chickpea (Cicer arietinum L.), commonly known as gram, is one of the important pulse crops in Bangladesh. Chickpea is the 3rd most important pulse crop and about 15% of the world’s total pulse productions belong to this crop (FAO, 2010). Among the major pulses that grown in Bangladesh chickpea ranked 5th in area and production but 2nd in consumption priority (BBS, 2010). Physiological and pathological reasons are responsible for low yield of chickpea. Flower and pod droppings play an important role for the lower yield of chickpea
