Abstract:

Potassium fertilization is often ignored in cereal-based cropping systems assuming sufficient K reserves in the alluvial soils of north-western India. However, the responses to K have now widely reported due to continuous mining and little additions through external sources. Little known on the effects of integrated K management on soil biological properties and yield performance of corn grown in sequence with wheat. A field experiment was conducted during 2010-2012 to find out the performance of corn (Zea mays L.)–wheat (Triticum aestvum L. emend Fiori & Paol.) cropping system with K fertilization through muriate of potash and farmyard manure (FYM) at New Delhi, India. The experiment was laid out in the randomized block design with seven treatments replicated thrice. Results revealed that treatment applied with 90 kg K supplemented 60 kg K through MOP and 30 Kg K through FYM significantly increase grain yield (100.9% and 99.3%) and stover yield (45.8% and 33.6%) during 2010 and 2011 respectively in the corn crop. A positive correlation observed between yield and soil biological properties, viz., bacterial population, actinomycetes, cellulose degrading bacteria, phosphorus solubilizing bacteria, potassium solubilizing bacteria, dehydrogenase activity, phosphatase activity, fluorescein diacetate and β-glucosidase. It concluded that application of FYM could be an alternative option for sustainable management of agricultural land and restore its fertility compared to the use of K fertilizers.
