Description A field experiment entitled “Response of rabi pigeonpea to different
nutrigation levels”was carried out on sandy clay soils at Water Technology Centre,
College Farm, College of Agriculture, Rajendranagar, Hyderabad during rabi season,
2012-13.
There were eight treatments in total, of which six were nutrigation treatments
based on surface drip method of irrigation, other two with RDF (100, 80, 60 % N with
50 or 100 % P2O5) application with drip irrigation and furrow irrigation with RDF
application replicated thrice in RBD. Surface drip irrigation system consisted of eight
treatments comprises of 16 mm integral dripper lines laid out on the ground surface
between two rows with emitters spaced at 0.50 m apart delivering 4 L h-1.
Plant height of rabi pigeonpea was not influenced significantly by drip nutrigation
treatments. Significantly higher leaf area index (LAI) and dry matter (g plant-1) were
recorded by drip nutrigation of 100 % N + 100 % P2O5 followed by drip nutrigation of
100 % N + 50 % P2O5 and significantly lower LAI and dry matter (g plant-1) were
observed in furrow irrigation with 100 % RDF under conventional soil application at all
growth stages.
Pods plant-1 (77.9) and seed yield plant-1 (0.54 kg plant-1) were significantly
higher with drip nutrigation of 100 % N + 100 P2O5, whereas furrow irrigation with 100
% RDF under conventional soil application recorded significantly lower pods plant-1
(61.8) and seeds plant-1 (0.38 kgplant-1). Whereas, Yield attributes viz., branches plant-1,
seeds pod-1and test weight were not significantly influenced by drip nutrigation
treatments.
Significantly higher seed yield (772 kg ha-1), stalk yield (4618 kg ha-1) and total
dry matter of rabi pigeonpea (5389 kg ha-1) were noticed by drip nutrigation of 100 % N+ 100 P2O5and the lowest was recorded in furrow irrigation with 100 % RDF under
conventional soil application (515 and 2523 kg ha-1 of seed and total dry matter,
respectively). Protein yield also follow the similar trend as like that of seed yield.
Plant nutrient uptake under drip nutrigation of 100 % N + 100 P2O5 was
significantly higher and lower nutrient uptake was noticed with furrow irrigation with
100 % RDF under conventional soil application at different growth stages of crop
growth.
Drip nutrigation of 100 % N + 100 P2O5 recorded higher water productivity (2.24
kg ha mm-1) and was on par with drip nutrigation of 100 % N + 50 P2O5 (2.20 kg ha
mm-1) and significantly lower water productivity (1.37 kg ha mm-1) was recorded by
furrow irrigation with 100 % RDF under conventional soil applicaton.
Based on the results obtained in the present investigation, It can be concluded that
pigeonpea can be grown as rabi crop under Rajendranagar conditions under drip
fertigation with 100 % N + 100 % P2O5 for realising higher seed yield (772 kg ha-1) and
was found remunerative and was observed that growing rabi pigeonpea under drip
water productivity (2.24 kg ha mm-1).
