Crop diversification is essential in lowland rice cropping systems to achieve sustainability, improve soil health, and as a climate-resilient practice reduce greenhouse gas (GHG) emissions. A life cycle assessment (LCA) was conducted for the farms west-coast region of India assess environmental impact rice–rice rice–cowpea systems. The (LCIA) evaluated “cradle-to-gate” perspective. higher energ...
The objectives of this research were to investigate influences of energy inputs and energy forms on output levels and evaluation of CO2 emissions for hazelnut production in Guilan province of Iran. Moreover, the sensitivity analysis was done by marginal physical productivity (MPP) method for energy inputs and energy using linear regression. Initial data were collected from 120 orchar...
Abstract Rainfall and land use/land cover changes are significant factors that impact the soil erosion processes. Therefore, present study aims to investigate of rainfall in current future scenarios deduce losses using state-of-the-art Revised Universal Soil Loss Equation (RUSLE). In this study, we evaluated long-term (period 1981–2040) through statistical measures used subsequently loss predic...
The present investigation was conducted to determine the feed quality of New Sudan grass varieties. On average, highest plant height found in variety Nika (274 cm) 2019-2020. These rates Sputnitsa and Aleksandrina were loer by 23 30 cm, respectevely. yield green matter after two cuts new 41.0 t ha-1 9.59 hay. recognized varieties varied range 35.0-36.0 7.98-8.28 ha-1. maximum protein content fo...
Abstract To estimate energy use efficiency for sweet potato production in Bangladesh under subtropical climatic conditions, a study was conducted with 60 individuals (12 producers each variety) by using structural questionnaire. The results revealed that the majority of input consumed pre-harvest activities (22,313.55 MJ ha−1 or 90.85%), which fertilizer application (36.84%) and irrigation (35....
A field experiment was conducted during 2013-14 to 2015-16 at Central Soil Salinity Research Institute, Regional Station, Lucknow find out the alternate rice (Oryza sativa L.)- wheat (Triticum aestivum L.) cropping system under partially reclaimed sodic soils. Four systems, viz. L.), sorghum (Sorghum bicolor)-berseem (Trifolium alexandrinum), sweet basil (tulsi) (Ocimum basilicum L.)-matricaria...
Objective: The aims of this study were to determine energy efficiency and CO2 use pattern of grape production in Zanjan province, Iran by a non-parametric method of data envelopment analysis (DEA). Methods: Initial data were collected using a face to face questionnaire from 42 orchards in Abhar city of Zanjan province which is one of the most important centers of grape production in ...
Due to the threat posed by spread of invasive plant species, there is an urgent need develop effective methods eradicating and managing their biomass. The aim study was examine selected plants in terms use for energy purposes find out whether they can be a raw material production second-generation biofuels. First, chemical compositions were determined. higher heating value (HHV) lower (LHV) als...
Toprak erozyonu doğal kaynakların sürdürebilirliğini, sosyal ve ekonomik gelişmeyi, karasal sucul ekosistemi tehdit eden dünya çapında çevresel bir sorundur. Ülkemizde insanların kaynaklar üzerine baskısının artmasıyla erozyon miktarı artmış yaşamsal ekosistem üzerinde olumsuz etkilere neden olmuştur. Meydana gelen bu etkiyi azaltmaya yönelik önlemler alınabilmesi için havzada toprak kaybı mikt...
In the present study, the energetic and economic modeling of lentil and chickpea production in Esfahan province of Iran was conducted using adaptive neuro-fuzzy inference system (ANFIS) and linear regression. Data were taken by interviewing and visiting of 140 lentil farms and 110 chickpea farms during 2014-2015 production period. The results showed that the yield and total energy consumpti...
