INM in forage sorghum (Sorghum bicolor L. Moench) during summer season

A field experiment entitled ¿Effect of integrated nutrient management on growth, content and uptake of nutrients as well as quality of forage sorghum (Sorghum bicolor L. Moench) during summer season¿ was conducted during summer seasons of 2012 at Main Forage Research Station, Anand Agricultural University, Anand. Total twelve treatments comprising of three N and P treatments T1 : 60-40 (N-P kg ha-1), T2 : 80-40 (N-P kg ha-1) and T3 :100-40 (N-P kg ha-1), nine bio fertilizers treatments T4 : 60-40 (N-P kg ha-1) + Azospirillum, T5 : 80-40 (N-P kg ha-1) + Azospirillum, T6 : 100-40 (N-P kg ha-1) + Azospirillum T7 : 60-20 (N-P kg ha-1) + PSB, T8 : 80-20 (N-P kg ha-1) + PSB, T9 : 100-20 (N-P kg ha-1) + PSB, T10 : 60-20 (N-P kg ha-1) + Azospirillum + PSB, T11 : 80-20 (N-P kg ha-1) + Azospirillum + PSB and T12 : 100-20(N-P kg ha-1) + Azospirillum + PSB were tested in a randomized block design with four replications. In light of the results it is concluded that the application of 100-40 N-P kg ha-1 + Azospirillum recorded maximum green forage yield with good quality of forage sorghum variety (GFS-4) along with sustaining soil fertility at harvest under middle Gujarat soil conditions.
