Abstract: A field experiment was conducted at Krishi Vigyan Kendra, Hadonahalli, Doddaballapura Bangalore rural district, to study the influence of lignite humin (LH) and poultry manure humin (PMH) on maize growth, yield and uptake of major nutrients in acid soil of eastern dry zone of Karnataka. The results revealed that application of 100% RDF + FYM @ 10 t ha-1 (T2:POP) recorded higher growth and yield parameters viz., plant height (217.70 cm), number of leaves plant-1 (13.93), cob length (17.29 cm), number of kernel rows cob-1 (16.90), number of kernels row-1 (36.60) and test weight 100 seed-1 (32.86 g). Similarly, significantly higher maize kernel (8070 kg ha-1) and stover yield (9948 kg ha-1) were recorded in the same treatment and which was found on par with treatment T7 (PMH @ 2.5 t ha-1 + FYM @ 7.5 t ha-1) and T3 (LH @ 2.5 t ha-1 + FYM @ 7.5 t ha-1) and T8 (PMH @ 5 t ha-1 + FYM @ 5 t ha-1). In all these treatments NPK nutrients were applied as per recommended dose of fertilizers. Significantly higher total nitrogen content in maize kernel (1.65%) and stover (0.89%) was observed in T2 followed by T7, T3 and T8 treatments and found on par with each other. Whereas, there was no significant differences observed among the treatments for total phosphorus and potassium content in maize crop. Significantly higher total uptake of major NPK nutrients (192.65, 41.75 and 134.37 NPK kg ha-1, respectively) was observed in T2 and found on par with T7, T3 and T8 treatments. These results clearly indicate that the humin residue of poultry manure and lignite after extraction of humic acid can be used for maize cultivation to the tune of 5 t ha-1 and 2.5 t ha-1, respectively along with 100% NPK + FYM (@ 5 t ha-1 with PMH or @7.5 t ha-1 with LH) without any detrimental effect on maize productivity.
