Abstract
The goal of this study is to identify the optimum NPK fertilization to maximize yield and productivity under local environmental constraints. To address this concern, a field experiment was conducted at Agronomy Research Farm, The University of Agriculture, Peshawar, during the rabi seasons of 2019–2020 and 2020–2021 in a randomized complete block design (RCBD) withthree replications. Treatments consisted of five Chinese wheat hybrids (18A-1, JM-1215, JM-1683, JM-1216, H-1) and one Australian hybrid (WS-1) with two local checks (Wadan-17 and Pirsabak-15) and two NPK levels, i.e., basal dose (120-90-60 NPK kg ha−1) and 25% higher thanbasal dose (150-112-75 NPK kg ha−1). The results of the two years’ experimentation exhibited that wheat hybrid WS-1 produced higher tillers (444 and 423 m−2), leaf area (32.7 and 30.7 cm2), leaf area index (5.0 and 5.4), plant height (105.3 and 103.1 cm), spike length (21.9 and 21.5 cm), spikes (329 and 322 m−2), grains spike−1 (59 and 58), thousand grain weight (62.2 and 62.2 g) and biological yield (9769 and 9906 kg ha−1) as compared to local check varieties. Wheat hybrids WS-1, JM-1683, H-1 and 18A1 produced 31%, 27%, 26% and 26% higher grain yield than local check Pirsabak-15, respectively, while a higher harvest index (61 and 59%) was noted for JM-1683 in both years. Application of NPK at the rate of 150-112-75 kg ha−1 increased emergence (87 m−2), tillers (421 and 407 m−2), leaf area (23 and 20.5 cm2), leaf area index (3.3), plant height (98.2 and 96.9 cm), spike length (15.9 and 16.3 cm), spikes (317 and 314 m−2), grains spike−1 (43), thousand grain weight (56.5 and 56.3 g), biological yield (9057 and 9163 kg ha−1) and grain yield (3702 and 3778 kg ha−1) compared to the lower level of NPK (120-90-60 kg ha−1). It is concluded that Chinese wheat hybrid JM-1683 and Australian hybrid WS-1 responded better to the higher level of NPK (150:112:75 kg ha−1) in terms of grain yield and its components and are therefore recommended for the agro-climatic condition of the Peshawar valley.
