Abstract:
A field experiment was conducted during rabi season of 2019-20 to assess the influence of different level of calcium and potassium thiosulphate on growth, yield and yield attributing characters of maize (Zea mays L.) at Crop Research Centre, RPCAU, Pusa, Bihar. The experiment was conducted in randomized block design with four replications and twelve treatments at different level of calcium and potassium thiosulphate @ 0, 15, 30 & 60 L/ha were applied according to treatments. Nitrogen, phosphorus and potassium were applied as urea, urea phosphate and potassium sulphate in all the treatments, respectively. In treatments T1 to T7, the Calcium and potassium thiosulphate were applied through drip, while in treatment T8 to T12 calcium and potassium thiosulphate were applied as band placement along with potassium sulphate. The experimental results indicated that treatment T7 (150:75:38 N-P2O5-K2O kg/ha + 30 L CaTS/ha + 30 L KTS/ha- Drip) produced significantly higher weight of cobs plant-1 (150.1 g), weight of grains cob-1 (121.6 g), weight of stones cob-1 ((21.3 g) and 100-grain weight (32 g), maximum grain yield (9063.0 kg ha-1), stover yield (7951.3 kg ha-1) and stone yield (1591.7 kg ha-1). Economics of different treatments indicated that by higher grain yield, treatment T7 (150:75:38 N-P2O5-K2O kg/ha + 30 L CaTS/ha + 30 L KTS/ha- Drip) exhibited maximum gross return, net return and B:C ratio of ₹ 184163 ha-1, ₹ 124905 ha-1 and 2.11 respectively.
