Impact of soil fertility characteristics on artificial fertility gradient approach developed using sorghum (Sorghum bicolor) in Alfisols

In the advent of precision agriculture, applying fertilizer based on soil testing is a crucial tool to prescribe nutrient levels for crops, increase use efficiency and production. A field experiment was conducted in farmer's Dindigul district, Southern agro-climatic zone Tamil Nadu ascertain effect artificial fertility gradient method fertility, green fodder production sorghum (Sorghum bicolor (L.) Moench) (var. CO 30) absorption. technique has been investigated produce recommendations location-specific red soils (Alfisols, Typic Rhodustalf). The experimental separated into three equal strips: strip I, II, III, which received applications graded ertilizer N0P0K0, N1P1K1, N2P2K2, respectively. Urea, single super phosphate, muriate potash fertilizers, respectively, were used apply NPK. As crop, S. raised. N1 level set general recommendation feed sorghum, while P1 K1 values soil’s ability fix 100 kg ha-1 phosphorus potassium, Plant samples taken at harvest time, their NPK content uptake determined. With addition doses nitrogen, potassium Strip II & III increased soil's available N, P K status substantially order I<II<III minimize heterogeneity population , management strategies employed, prevailing climate conditions induce variations same field. outcomes showed that crop yields (Strip – 25.01 t ha-1) significantly impacted by application amounts fertilizers.
