PERFORMANCE OF DIFFERENT MUSTARDCULTIVARS UNDER IRRIGATED AND RAINFED CONDITIONS Arif Khan and Muhammad Arif Department of Agronomy, Faculty of Crop Production Sciences The University of Agriculture, Peshawar-Pakistan October, 2021 ABSTRACT Pakistan has been facing a prolonged shortage of edible oil; a large quantity of edible oil is imported annually from other countries to fill the gap between local production and consumption. Two separate experiments were conducted to check the performance of different mustard cultivars under irrigated and rainfed conditions. Experiments were conducted at Agronomy Research Farm, The University of Agriculture Peshawar in 2020. Both experiments were carried out in randomized complete block design having four replications. The studied factors were i.e. varieties (KS-M-74, KS-M-75, ME-745, Song-1, China, Swabi and Bio-M) and the irrigation regimes (irrigated and rainfed). Experimental results showed that higher days to emergence (8 days), emergence (96.5 m-2), silique plant-1 (461.8), silique m-2 (7634) and harvest index (19.8%) was recorded for China variety, while maximum 1000 grains weight (4.0 g), protein content (26.2%), glucosinolates (125 µ mol g-1) were recorded for ME-745. The maximum days to first flower (110 days), days to 50% flowering (120 days), days to maturity (176 days), plant height (194 cm), grains silique-1 (23), biological yield (7375 kg ha-1), grain yield (1385 kg ha-1), oil content (48.6%), oil yield (673.3 kg ha-1) and oleic acid (46%) was recorded for Swabi and plant population (262731 ha-1), linolenic acid (13.4%) erucic acid (60%) were recorded for Bio-M, KS-M-75 and Song-1, respectively. In case of the irrigation regimes, maximum emergence (87 m-2), days to maturity (169 days), plant height (183 cm), silique (425 plant-1), silique (6859 m-2), grains silique-1 (18), 1000 grains weight (3.81g), biological yield (6905 kg ha-1), grain yield (1206 kg ha-1), harvest index (17.4%), oil content (47.8%), oil yield (576.3 kg ha-1), protein content (25.8%), linolenic acid (13.1%), and erucic acid (60%) were recorded under irrigation condition, while higher days to emergence (9 days), days to flowering (75 days), days to 50% flowering (92 days), plant population (255427 ha-1), glucosinolates (117 µ mol g-1) and oleic acid (34.3%) were recorded under rainfed condition. It is concluded that Swabi variety performed better in terms of seed yield under irrigated conditions as compared to other varieties.
