Abstract

A field experiment was conducted during Kharif-2021 at Main Agricultural Research Station, Raichur, Karnataka to study the “Effect of enriched FYM levels and fertilizers levels on yield and nutrient uptake by hirsutum cotton variety (Gossypium hirsutum L.)’’. Among enriched FYM levels, application of 7.5 t ha-1 enriched FYM through spot application (M3) recorded significantly higher total dry matter production (287.48 g plant-1 at harvest), seed cotton yield (2629 kg ha-1), harvest index (0.210), uptake of N (100.07 kg ha-1), P2O5 (24.44 kg ha-1), K2O (116.85 kg ha-1), Fe (266.10 g ha-1) and Zn (1249.14 g ha-1) by hirsutum cotton variety. Among sub plot treatments, significantly higher total dry matter production (293.39 g plant-1 at harvest), seed cotton yield (2676 kg ha-1), harvest index (0.210), uptake of N (100.83 kg ha-1), P2O5 (24.63 kg ha-1), K2O (117.57 kg ha-1), Fe (1267.51 g ha-1) and Zn (273.81 g ha-1) were noticed at application of 150 per cent RDF (F3) over remaining two other treatments i.e., 125 per cent RDF and 100 per cent RDF.

Conclusion

From the results of the present study, it is concluded that there was significant response of enriched FYM application on cotton crop. Among main plot treatments (i.e., enriched FYM levels), application of 7.5 t ha-1 enriched FYM through spot application recorded significantly higher total dry matter production, seed cotton yield and nutrient uptake. There was linear increase in dry matter production, seed cotton yield (kg ha-1), harvest index and nutrient uptake with increasing levels of major nutrients. Among three levels of NPK application, 150 per cent RDF found superior in yield and nutrient uptake over 125 % and 100 %.
