Description |
The field experiment was conducted at Singanahalli village of model watershed Dharwad in Northern transition zone of Karnataka on clay soil to study the integrated nutrient management practices in maize-chickpea sequence cropping under broad bed and furrow under rainfed conditions during 2010-11 and 2011-12. The experiment was laidout in split plot design with two land management systems as main plots and five INM treatments as sub plots for both maize and chickpea crops in sequence. Significantly higher interaction for maize grain yield (7322 kg ha-1) and stover yield (9.05 t ha-1) were recorded with broad bed and furrow along with the application of FYM (7.5 t ha-1) + RDF (inorganics 100:50:25 kg NPK ha-1) + ZnSO4 10 kg ha-1. In chickpea, significantly higher grain yield and haulm yield (1640 kg ha-1 and 1987 kg ha-1, respectively) were recorded with interaction of broad bed and furrow along with application of 10:25 kg NP ha-1 through inorganics only + PSB @ 1250 g ha-1 + Rhizobium @ 1250 g ha-1. Moisture conservation was significantly higher with BBF compared to flatbed. Significantly higher interaction in maize was recorded in BBF x RDF interaction viz., broad bed and furrow along with application of FYM (7.5 t ha-1) + RDF (inorganics 100:50:25 NPK ha-1) + ZnSO4 10 kg ha-1 for higher gross returns (` 73314 ha-1) and net returns (` 48559 ha-1) compared to rest of the interactions. In chickpea, integration of broad bed and furrow along with application of 10:25 kg NP ha-1 through inorganics only + PSB @ 1250 g ha-1 + Rhizobium @ 1250 g ha-1 recorded significantly higher gross returns (` 47248 ha-1), net returns (` 36023 ha-1) and benefit cost ratio (4.21) compared to other interactions. In maize-chickpea sequence cropping the interaction of BBF and RDF i.e., application of FYM (7.5 t ha-1) + RDF (inorganics, 100:50:25 NPK ha-1) + ZnSO4 10 kg ha-1 for maize followed by RDF for chickpea i.e., application of 10:25 kg NP ha-1 through inorganics only + PSB @ 1250 g ha-1 + Rhizobium @ 1250 g ha-1 recorded significantly higher net returns (` 87357 ha-1) and benefit cost ratio (3.43 ) compared to rest of the interactions. |
