“…The foliar application of humic acid stimulates the plant parameters like spike length and number, number of grains and 1000 grain weight (Khandil et al, 2016). Humic acid play a signi cant role in improving wheat yield and is used to meliorate or decrease the negative impact of stress (Azarpour et al, 2012). According to (Burhan and AL-Taey, 2018), the amendment of humic acid is a pollution free technique of agricultural.…”

The use of chemical fertilizers for getting higher yield of crop imposes negative effects on soil properties. The application of organic amendments in combination with synthetic fertilizer to improve the growth of crop hence reduce its effect on soil has become imperative. A field experiment was carried out at research farm of The University of Agriculture Peshawar, to study the effect of Humic acid (HA) and farmyard manure (FYM) along with chemical fertilizers on N, P, and K use efficiency and yield of wheat crop during rabi 2020-21. Humic acid and FYM was applied at the rate of 10 kg ha-1 and 10 tons ha-1 respectively while the source of nitrogen was applied at the rate of 90 kg ha-1 and 120 kg ha-1, the source of phosphorous was applied at the rate of 60 kg ha-1 and 90 kg ha-1 and the source of potassium was applied at the rate of 45 kg ha-1 and 60 kg ha-1. Treatments were arranged in randomized complete block design with three replications. Application of HA and FYM along with different levels of synthetic fertilizers significantly improved plant height, biological yield and 1000-grain weight as compared to control. The results indicated that the application of synthetic fertilizers alone significantly increased grain yield from 2535 kg ha-1 in control to 3495 kg ha-1 that was further improved to 3717 kg ha-1 when combined with HA and to 3949 kg ha-1 when applied with FYM. The combined application of FYM and HA with 75% NPK resulted in higher yield than 100% NPK suggesting fertilizers reduction with improvement in yield. Furthermore, the study assessed the total nutrient uptake and use efficiency, indicating that FYM and HA application with NPK fertilizer enhanced the uptake of N, P, and K by wheat plants. Notably, the highest nutrient use efficiency was recorded in plots treated with FYM and HA along with 75% NPK fertilizer. These findings suggest the potential of integrated nutrient management practices to enhance wheat productivity and soil fertility.

In this study, energy use efficiency (EUE) and greenhouse gas emissions (GHG) in wheat production were defined, and the energy equivalents (EE) of the inputs in production per unit production area, EUE and GHG values of the product were computed. The data used in the study were obtained from 175 different wheat producing enterprises in 2021 by conducting face-to-face surveys according to the proportional sampling method. In the study, the amount of direct (DE) and indirect energy (IE) use in wheat production and their shares in total energy consumption were defined. According to the results of the study, total energy input (EI) in wheat production was com-puted as 19,024.21 MJ/ha and energy output (EO) as 80,585.40 MJ/ha. It was defined that the input with the highest energy consumption was fertili-zation with a value of 8748.38 MJ/ha. This was followed by seed energy input 4626.79 MJ/ha (24.32%), fuel energy 2697.25 MJ/ha (14.18%), irriga-tion energy 2362.50 MJ/ha (12.42%), chemicals energy 269.19 MJ/ha (1.41%), machinery energy 309.52 MJ/ha (1.63%), human labor energy 10.58 MJ/ha (0.06%). EUE, energy productivity (EP), specific energy (SE) and net energy (NE) yield values were 4.24, 0.29 kg/MJ, 3.47 MJ/kg and 61561.19 MJ/ha, respectively. Total GHG emission for wheat production was computed as 3784.60 kgCO2-eq/ha. The highest share of total GHG emissions belonged to seed (59.41%). Seed was followed by irrigation (16.84%), nitrogen fertilizer use (14.60%), phosphate fertilizer use (3.99%), fuel use (3.49%), chemicals use (0.98%), machinery use (0.58%) and hu-man labor (0.10%). In addition, the GHG ratio in wheat production was computed as 0.69 kgCO2-eq/ha.

Energy has a key role in social-economic development of countries. Efficient use of energy in agriculture is one of the conditions for sustainable production. In this article, evaluation of energy balance and energy indices under dry land farming pumpkin in north of Iran (Guilan province) were investigated. Data were collected from 72 farms by used a face to face questionnaire method during 2011 year in Guilan province. By using of consumed data as inputs and total production as output, and their concern equivalent energy, energy balance and energy indices were calculated. Energy efficiency (energy output to input energy ratio) for seed and fruit in this study were calculated 0.16 and 1.43 respectively; showing the affective use of energy in the agro ecosystems pumpkin production. Energy balance efficiency (production energy to consumption energy ratio) for seed and fruit in this study were calculated 0.09 and 1.54 respectively; showing the affective use of energy in the agro ecosystems pumpkin production.
