ABSTRACT
A research trial at farmer’s field was conducted to study the production competition of hybrid (CS-200, cv) and local variety (Azam cv.) under the same application of fertilizer treatment and dozes during summer 2015. The field experiment was laid out in randomized complete block design with split plot arrangements having two maize varieties in main pot and six levels of fertilizer treatments in sub pots repeated four times. Fertilizers treatments were made from the application of Nitrogen (N), Phosphorus (P2O5) and farmyard manure (FYM) which was collected from cattle barnyard. A total of six fertilizer treatments were used viz T1 = control (no application of inputs), T2 = 130 kg N ha-1, T3 = 130 kg N ha-1 + 90 kg P2O5 ha-1 T4 = FYM @ 20000 kg ha-1, T5 = 130 kg N ha-1 + 90 kg P2O5 ha-1 + FYM @ 20000 kg ha-1 and T6 = 65 kg N ha-1 + 45 kg P2O5 ha-1 + FYM @ 20000 kg ha-1. The results indicated that both maize varieties (hybrid and local) showed different responses to different fertilizer treatments application but combined used of farm yard manure, N and P2O5 in (T5) and (T6) significantly increased yield and yield traits of Hybrid CS-200 and Azam variety than rest of the fertilizers treatments. The significantly maximum plant height of Azam cv. (260 cm) and hybrid (247cm) were recorded in treatment T5 (N- P2O5@ 130-90 kg per hectare + 20 ton per hectare FYM) followed by T6 (50-45) kg N, P2O5 ha-1 + FYM @ 20000 kg ha-1. The Azam plants were taller than hybrid. The treatment (T5) significantly yielded more grain (6806 kg ha-1) and (5106 Kg ha-1) from hybrid (CS-200) and a local maize Azam cultivar, respectively. Similarly, stover yield of hybrid (10378 Kg ha-1) and Azam (7708 Kg ha-1) were more in T5 than the other treatments. So, it is concluded that the combined application of farmyard manure and balanced inorganic fertilizer (Nitrogen + Phosphorus) gave significant yield production in terms of grain and biological yield in clay soil
