A field experiment was conducted at research and demonstration block of Research Institute on Organic Farming, UAS, GKVK, Bengaluru during 2020-21 to study the influence of organic sources on growth and yield of maize in maize-cowpea cropping sequence. The experiment was laid out in factorial randomised block design with three replications. The experiment consists of 15 treatment combinations of three levels of N equivalent and five organic sources along with absolute control and UAS-B package. The experimental soil was red sandy loam having low organic carbon (0.45 %) and medium in N (289.4 kg ha-1), P2O5 (28.6 kg ha-1) and K2O (235.2 kg ha-1) content. The experimental results indicated that application of bio-compost at 125 % N equivalent resulted in higher plant height (221.5 cm), leaf area (7949 cm² plant-1), total dry matter accumulation (201.1 g plant-1) and kernel (107.47 q ha-1) and stover yield of maize (154.60 q ha-1) followed by poultry manure at 125 per cent N equivalent and found significantly superior over other treatments in the studies. However, UAS-B package (150:75:40 kg N: P2O5: K2O ha-1) recorded significantly higher plant height (229.9 cm), leaf area (8197 cm² plant-1), total dry matter accumulation (213.6 g plant-1) and kernel (111.96 q ha-1) and stover yield (161.13 q ha-1) and was on par with application of bio-compost at 125 per cent N equivalent.
