Effect of Crop Geometry, Intercropping Systems and INM Practices on Cob Yield and Nutrient Uptake of Baby Corn
N. Thavaprakaash and K. Velayudham

Abstract: Field experiments were conducted at Eastern Block farm, Tamil Nadu Agricultural University, Coimbatore during kharif 2002 (June to September) and summer 2003 (February to May) seasons to study the impact of varied crop geometry, short duration intercrops and INM practices on production potential of baby corn based intercropping systems. Two crop geometry levels (45X25 cm and 60X19 cm) and two short duration intercrops (Amaranthus and green gram) along with control (no intercrops) were taken in main plot. Recommended dose of fertilizers (100% NPK-N1) along with three INM practices [50% NPK + FYM + Azospirillum + phosphobacteria (N2), 50% NPK + poultry manure + Azospirillum + phosphobacteria (N3) and 50% NPK + goat manure + Azospirillum + phosphobacteria (N4)] were assigned to subplot in a split plot design. The trial was replicated thrice. The experimental results revealed that crop geometry and INM treatments significantly influenced on nutrient uptake of baby corn. Baby corn spaced at 60X19 cm recorded higher uptake of N, P and K as compared with 45X25 cm spacing. Intercropping systems did not influence the nutrient uptake. All the INM practices showed higher NPK uptake than N1. Among the three INM practices, the treatments N3 and N4 recorded significantly higher values than N2. Almost similar results were obtained in green cob yield of baby corn. BEY was higher with S2 than S1. Intercropped baby corn produced higher BEY than sole baby corn. The treatments N3 and N4 recorded significantly more BEY values as compared to N2 and N1. The correlation between NPK uptake and baby corn yields was positive and significant, however, between BEY and nutrient uptake was not significant during both the seasons.
