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). |
