Abstract:
A field experiment was conducted during Zaid 2021 at Crop Research Farm, Effect of Phosphorus and Potassium levels on growth and yield of Baby corn (Zea mays L.) Department of Agronomy, SHUATS, Prayagraj (U.P) to study Treatments consists of 3 levels of Phosphorus viz, 45 kg, 60 kg, 75 Kg P2O5/ha and 3 levels of Potassium viz, 20, 30 and 40 kg K2O/ha as basal. There were 10 treatments each being replicated thrice treatments included, 45 kg P/ha + 20 kg K/ha, 45 kg P/ha + 30 kg K/ha, 45 kg P/ha + 40 kg K/ha, 60 kg P/ha + 20 kg K/ha, 60 kg P/ha + 30 kg K/ha, 60 kg P/ha + 40 kg K/ha, 75 kg P/ha + 20 kg K/ha, 75 kg P/ha + 30 kg K/ha, 75 kg P/ha + 40 kg K/ha, Control Plot (90:40:20) NPK Kg/ha and laid out in Randomized Block Design. The results revealed that treatment T9: (75 kg P/ha + 40 kg K/ha) recorded highest plant height (95.40), maximum on no of leaves (10.83), dry weight (77.33), no of cobs (2.77), cob length (12.97), cob weight with husk (28.03), cob weight without husk (9.70), corn yield (5214 Kg/ha), Stover yield (20.18 t/ha), B.C ratio (2.50) in Baby corn.
