A field experiment to study the effect of water and light stresses imposed at flowering stage and foliar application of auxins on flower abscission and yield of pigeonpea short duration cv. ICPL 288 indicated a significant increase of 5 and 8 per cent of flower drop with concomitant decrease of 28 and 42 per cent seed yield with water and light stresses respectively. In general, foliar application of NAA 20 ppm enhanced pods plant and reduced the flower drop to an extent of 15 per cent and resulted in an increased seed yield by 23% over control plants indicating a favourable impact of NAA nutrition on seed yield of pigeonpea.
