Effect of Different Organic and Inorganic Fertilizers on Growth and Yield Parameters of Maize (Zea mays L.)

Abstract

A field experiment was conducted during summer season of 2021-22 at Zonal Agriculture Research Station, Chhindwara, and analytical works were done in laboratories Department of Soil Science & Agricultural Chemistry, College of Agriculture, JNKVV, Jabalpur (MP). The objective of experiment was to find out the effect of different organic and inorganic fertilizers on growth parameters and yield of maize. The experiment was laid out in a randomized block design with ten treatments and three replications. The treatments were, T1 - Control (0:0:0), T2 - 100% RDF (120:60:40 kg NPK ha-1), T3 - 75% RDF, T4 - 50 % RDF, T5 - FYM 10 t ha-1 + Azotobacter, T6 - 100 % RDF + 5 t ha-1 FYM, T7 - 75 % RDF + 5 t ha-1 FYM, T8 - 50 % RDF + 5 t ha-1 FYM, T9 - 100 % RDF + 5 kg Zn ha-1 and T10 - FYM 5 t ha-1 (State practice). The result revealed that the application of Application of T6 - 100 % RDF + 5 t ha-1 FYM was recorded higher values of all the growth parameters and yield of maize at harvest viz., plant height (212.22 cm), dry matter accumulation (296.15 g/plant), leaf area index (4.335 %), crop growth rate (CGR) (24.375), relative Growth Rate (RGR) (2.711), grain yield (7844.41 kg/ha) and stover yield (14223.98 kg/ha).
