“…Humic acid (kg ha -1 ) The application of 20 Mg FYM ha -1 had increased leaves plant -1 , leaf area, leaf area index, plant height, and ear length of maize. The increased leaves plant and associated leaf area as well as plant height might be related to the improved permeability of soil ( Jat et al, 2019), water storage capacity of soil and optimized soil temperature ( Jia et al, 2013). These results are in line with the finding of Khan et al (2009), who reported increased growth and biomass of maize due to the application of FYM when compared to control plots.…”

M aize (Zea mays L.) is a cereal crop grown in almost all countries of the world. It has largely used as a staple food in Pakistan as well as other developing countries of the world. In Khyber Pakhtunkhwa, it is the 2 nd most important and grown crop after wheat (Triticum aestivum L.), whereas in Pakistan its rank is 3 rd . Maize crop has multiple uses like it is used as food, feed and raw materials for commercial product preparation (Khan et al., 2017). Pakistan economic survey show that maize was planted on 1.40 million ha land and produced 7.88 million tons with 5121 kg ha -1 average yield (MNSF&R, 2020). In Pakistan, maize production is lower than world leading countries due to less fertility of soil, improper usage and time of fertilizer application and several other agronomic management problems.

“…However, the productivity of NT systems compared to conventional cropping systems is still controversial. Since the productivity of NT depends on several interacting factors such as climatic conditions 11 , soil characteristics 1 , 12 , and other agricultural management activities 13 – 19 , the potential of NT to increase agricultural productivity remains highly uncertain.…”

No tillage (NT) is often presented as a means to grow crops with positive environmental externalities, such as enhanced carbon sequestration, improved soil quality, reduced soil erosion, and increased biodiversity. However, whether NT systems are as productive as those relying on conventional tillage (CT) is a controversial issue, fraught by a high variability over time and space. Here, we expand existing datasets to include the results of the most recent field experiments, and we produce a global dataset comparing the crop yields obtained under CT and NT systems. In addition to crop yield, our dataset also reports information on crop growing season, management practices, soil characteristics and key climate parameters throughout the experimental year. The final dataset contains 4403 paired yield observations between 1980 and 2017 for eight major staple crops in 50 countries. This dataset can help to gain insight into the main drivers explaining the variability of the productivity of NT and the consequence of its adoption on crop yields.

“…Crop residues incorporate a large number of nutrients in the soil for crop production and affect soil water movement, runoff, and infiltration. In a conservation agriculture (CA) system, successful management of crop residues is an integral part, and the maximum benefit of CA can only be achieved with in-situ management [8]. However, decomposition of crop residues has both positive and negative impacts on crop production.…”

Management of Crop Residues for Improving Input Use Efficiency and Agricultural Sustainability

et al. 2020

Crop residues, the byproduct of crop production, are valuable natural resources that can be managed to maximize different input use efficiencies. Crop residue management is a well-known and widely accepted practice, and is a key component of conservation agriculture. The rapid shift from conventional agriculture to input-intensive modern agricultural practices often leads to an increase in the production of crop residues. Growing more food for an ever-increasing population brings the chance of fast residue generation. Ecosystem services from crop residues improve soil health status and supplement necessary elements in plants. However, this is just one side of the shield. Indecorous crop residue management, including in-situ residue burning, often causes serious environmental hazards. This happens to be one of the most serious environmental hazard issues witnessed by the agricultural sector. Moreover, improper management of these residues often restrains them from imparting their beneficial effects. In this paper, we have reviewed all recent findings to understand and summarize the different aspects of crop residue management, like the impact of the residues on crop and soil health, natural resource recycling, and strategies related to residue retention in farming systems, which are linked to the environment and ecology. This comprehensive review paper may be helpful for different stakeholders to formulate suitable residue management techniques that will fit well under existing farming system practices without compromising the systems’ productivity and environmental sustainability.
