Research Topic: Response of transplanted pigeonpea (Cajanus cajan (L.) Millsp.) to different planting geometry
Objectives:- To evaluate performance of transplanted pigeonpea compared to late sown pigeonpea under rainfed condition.

Results:
Seed yield of Pigeonpea differed significantly among treatments. Significantly superior yield of Pigeonpea recorded in dibbling (T1) seeds on the same day of transplanting the pigeonpea seedlings in various crop geometry. Among transplanting treatments crop geometry of 90 x 20 cm (T2) recorded significantly higher yield of Pigeonpea, which was on par with 90 x 60 cm (T4), 90 x 90 cm (T5) and 120 x 30 cm (T6), compared to other treatments.
CONCLUSIONS
- Results of two year experimentation (2007-08 and 2008-09) on response of transplanted pigeonpea compared to dibbling seeds on the same day of transplanting under rainfed condition, dibbling of seeds recorded significantly higher yields.
- Hence transplanting may not be advisable in
Region-I, Zone-2 area under rainfed situation.

Probabla reasons for low yield in transplannted crop
I wish to know the probabla reasons for low yield in transplanted crop. The transplanted crop under late sown condition will have a better growth than direct seeded crop. With this object the experiment might have been planned. What made the transplanted crop to give low yield . Pleased if reply is given by the experimenter

Two years may be too short a
Two years may be too short a period to conclude. Transplanting may be useful in years where there is initial drought making it impossible to take up sowing of pigeonpea. Some trials have been taken up this year (2009 kharif) in the Telangana regions of Andhra Pradesh on transplanted pigeonpea under the NAIP component 3 led by CRIDA, Hyderabad. Results are yet to be obtained. As of now transplated crop is way ahead of drill sown pp. The purpose of transplanting, I understand, is to circumvent initial drought by raising nursery where limited water is used to raise plants that would be kept in waiting for a favourable time for taking up transplanting. Hence, the research design should include diffenent sowing dates as well.
