| Abstract | A field experiment was conducted at Raahat Agricultural Farm, Muridke, district Sheikhupura, Punjab Pakistan during 2019-2020 on loamy soil. The experiment consisting of five treatments, (wheat straw mixed with soil, water-soluble sulfur application and sulphuric acid application irrigated at CWR, irrigation at 125% of crop water requirement and farmer's practice with no irrigation schedule) with the recommended fertilizers dose for each treatment using a drip irrigation system. The total 5 treatments were tested statistically in a randomized complete block design with three replications. The pea variety Meteor was sown on 21st November 2019 with 30cm row-row and 20cm plant -plant spacing. A set of measurements were noted related to growth, crop production, and water productivity. The statistical results revealed that management practice T3 (application of sulphuric acid) to the pea crop irrigated at crop water requirement and fertigated with RFD, proved to be most superior treatment significantly increased the growth and yield contributing parameters as compared to the farmer's practice which had no irrigation schedule but recommended fertigation schedule was followed without any management practice. T3 took fewer days to germination (5.7 DAS), first flowering days (33 DAS), fruit setting (44.33 DAS), maximum plant height (59.8cm), gave a greater number of pods/plant (7.95), highest yield (8.81 t/ha). The growth and yield components were noted in descending order as T3 > T2 > T1 > T5 > T4. The sulphuric acid application resulted in a significant increase in micronutrient uptake by the plant; however, effect of its application on soil pH, available phosphorus, potassium and organic matter availability at the end of the experiment was not significant as indicated by soil analysis. Similarly, Water productivity (7.02kg/m3) was found higher in T3 as compared to other treatments due to better uptake of nutrients and improved bulk density. |
