Tillage, Water and Nitrogen Management Strategies Influence the Water Footprint, Nutrient Use Efficiency, Productivity and Profitability of Rice in Typic Ustochrept Soil

Abstract

The current study was conducted to assess how optimal tillage water and nitrogen management system are adopted to reduce various field inputs, to improve water footprint (WF), nutrient use efficiency (NUE), rice productivity and profitability. The W1 (CS to a depth of 5 cm) achieved significantly higher total water footprint (TWFP) compared to all other irrigation strategies. When N1 (control) and N2 (80 kg N ha−1) was used, the highest TWFP was observed. The rice transplanted on wide raised beds (WBed-TPR) (0.71 kg m−3) yielded the greatest water productivity (WPIRRI), followed by reduced tillage transplanted rice (RT-TPR) and conventional tillage puddled transplanted rice (CT-TPR). The physiological NUE values ranged from 33.3 to 50.6 kg grain/kg N absorption, the values decreasing as the N doses rose. According to the findings, WBed-TPR and RT-TPR plots similarly drank more moisture from the deeper profile layer than CT-TPR practice. In plots of CT-TPR and WBed-TPR, the yield contributing characteristics of rice all increased, while grain yield increased by 16.8% and 10.6% over NBed-TPR technique, respectively. Finally, CT-TPR reported with maximum cultivation costs, followed by NBed-TPR and the lowest in RT-TPR plots, although WBed-TPR had the highest net profit, B: C ratio.

Evaluation of Soil Characteristics for Agricultural Machinery Management and Cropping Requirements in AL Aflaj Oasis, Saudi Arabia

“…Ultimately, optimum field performance and soil structure for carrying out future plant cultivations in the arid lands, such as those of the Al Aflaj Oasis, which were affected by the overflow of water from the Al Aflaj springs in the ancient past, can be consistent with the operation of other types of agricultural equipment, such as chisel tillage of the soil. This is in agreement with Tyagi et al [30], who indicated that maintaining tillage operations with effective practices for managing water and soil nitrogen is promising as an applicable alternative to conventional farming techniques.…”

Conservation tillage and fertiliser management strategies impact on basmati rice (Oryza sativa L): crop performance, crop water productivity, nutrient uptake and fertility status of the soil under rice-wheat cropping system

“…Rice, commonly known as paddy, is a critical crop that supplies 19% of the world’s nutritional energy and serves as a staple food for about half of the global population ( Tyagi et al, 2022 ). To meet India’s food needs by 2050, it is projected that food supply will need to increase by 60% ( Tyagi et al, 2022 ). Rice uses 27% of global freshwater ( Bouman, Lampayan & Tuong, 2007 ).…”
