Growth and yield of pulses as influenced by irrigation levels in southern dry zone of Karnataka

Author(s): Shirgapure KH and Fathima PS
Abstract: A field experiment was conducted on a sandy loam soil at college of Agriculture V. C. Farm Mandya, UAS Bengaluru in kharif 2016 to study the effect of irrigation levels on productivity of pulses in southern dry zone of Karnataka for achieving optimum irrigation schedule and higher yield. The experiment was laid out in Split-plot Design with four levels of irrigation as main plot viz., irrigation at 60, 80, 100 per cent CPE (cumulative pan evaporation) and irrigation as per recommended irrigation practices in Southern Dry Zone of Karnataka. The pulses grown in Sub-plots were Greengram, Blackgram and Fieldbean. Analysis was done for crop equivalent yield. The results revealed that, higher growth and yield parameters of pulses viz., plant height (23.48 to 32.44 per cent), leaf area (93.39 to 30.41 per cent), dry matter production (30.68 to 36.32 per cent), number of pod (21.33 to 23.73 per cent), pod length (9.06 to 12.75 per cent) and haulm yield (9.09 to 12.41 per cent) recorded with irrigation at 80% fallowed by irrigation at 100% CPE as compared to recommended practice. However reduction in growth and yield parameters of pulses at 60 % CPE irrigation level as compared to recommended practice. Significantly higher greengram equivalent yield recorded with irrigation at 80% CPE (1710 kg ha-1) as compared to irrigation at 60 % CPE and recommended practice (1427 and 1502 kg ha-1, respectively) but was on par with irrigation at 100% CPE (1619 kg ha-1). The treatment combination of irrigation at 80 per cent CPE and blackgram recorded significantly higher greengram equivalent yield of 2201 kg ha-1 as compared to rest of the combinations. Hence scheduling irrigation at 80 per cent CPE in pulses enhances growth and yield in Southern Dry Zone of Karnataka.
