PRODUCTION POTENTIAL OF MAIZE AND MUSTARD UNDER DIFFERENT INTERCROPPING SYSTEMS IN MOISTURE DEFICIT SUB-TROPICAL AREAS OF JAMMU AND KASHMIR, INDIA

摘要

Field experiments were conducted at Dryland Research Sub-station, Rakh Dhainsar, Sher-e-Kashmir University of Agricultural Sciences and Technology, Jammu to study the effect of mustard and on the productivity of maize intercropping system in moisturedeficit sub-tropical areas of Jammu and Kashmir. Initially the experiment was laid out in a randomized block design with four mustard based intercropping systems as experimental treatments during rabioi 2008-09 and by keeping the ra 6/imposed intercropping systems as main plot treatments, four new maize based intercropping systems as sub-plot treatments with four replications. The maize from intercropping system of maize+cowpea preceded by mustard+fieldpea registered statistical higher grain and stoveryield as that recorded under sole maize preceded by mustard based intercropping systems and it was also produced more number of gains/cob and 1000-grain weight than other intercropping systems preceded by mustard based intercropping systems. Higher nutrient removal by maize was also recorded in maize+cowpea preceded by mustard+fieldpea system.
