“…Quantitative relations show how the system's benefits and costs are affected by energy consumptions. Determining energy efficiency has been the main subject of the majority of previous studies (e.g., Singh et al 2000;Karkacier and Goktolga 2005;Rafiee et al 2010;Zangeneh et al 2010;Pahlavan et al 2011;Bojacá et al 2012;Tabatabaie et al 2013). Some studies have published energy and economic analyses of rice crop alone (Pishgar-Komleh et al 2011).…”

Industrial agriculture is not efficient anymore due in particular to the use of nonrenewable energy such as fossil fuels. Organic agriculture is an alternative system that aims to reduce the consumption of fossil fuels, pesticides, and mineral fertilizers. Animal-crop systems present potential mutual benefits, but such systems have been rarely studied quantitatively. Here, we compare energy inputs and outputs of organic riceduck farming with conventional rice production in Mazandaran province, Iran. Our results show that the global energy input of organic rice-duck, 79,307 MJ ha . The most used energy was fuel, amounting to 40 % of total energy for organic rice-duck and 33 % for conventional rice. Then, machinery consumed 25 % of total energy for organic rice-duck and 20 % for conventional rice. Then, fertilizers consumed 20 % of total energy in the form of organic fertilizers for organic rice-duck versus 16 % in the form of mineral fertilizers for conventional rice. Overall, our findings show that organic rice-duck farming has more energy efficiency than conventional rice farming.

“…7) was more under green farming (1.26 kg MJ -1 ) as compared to CCM (0.56 kg MJ -1 ). This can be attributed to the differences in the level of technology and other characteristics of each treatment (Zangeneh et al, 2010). Specific energy was 55.6 percent less under green farming vs. CCM; indicating higher sustainability under the former.…”

“…Energy equivalence of inputs and output was sourced from Khan & Hossain (2007); Zangeneh et al (2010) and Zahedi et al (2014). Energy use efficiency, energy productivity, specific energy, energy intensiveness and net energy were calculated as per the methodology of Banaeian et al (2010) and Ghorbani et al (2011).The economics of various treatments was also worked out following standard techniques (Gomez & Gomez, 1984).…”

A study was taken up during 2014-16 for evaluating the potential of an organic package of practice towards integrated crop production (green farming) in comparison to conventional farmers' practice in West Bengal, India. Under green farming, compost was integrated with chemical fertilizer for soil management while organic plant/ pest management was undertaken utilizing Inhana Rational Farming (IRF) Technology. The study indicated higher yield (9.7 %), higher nutrient use efficiency and economic sustainability under green farming irrespective of study area or potato variety. Higher qualitative expression in terms of starch content, pulp pH, vitamin C etc. under green farming might be due to the organic plant management aimed at energization of plant biochemical functions. Soil quality development as noted under green farming might have been influenced by the onfarm produced compost containing rich self-generated micro flora (in order of 10 16 per colony forming unit.). The study indicated that green farming may serve as an efficient substitute of conventional farming towards yield sustenance, abatement of food toxicity and quality end product; through higher use of renewable energy and activation of plant physiological functions.Key words: green farming; organic plant management; energy use efficiency; soil quality; potato IZVLEČEK OVREDNOTENJE NABORA EKOLOŠKIH POSTOPKOV V INTEGRIRANI PRIDELAVI KROMPIRJA (Solanum tuberosum L.) V PRIMERJAVI S KONVENCIONALNO GLEDE NA PRIDELEK, KAKOVOST, ENERGETSKO UČINKOVITOST IN EKONOMIČNOSTZa ovrednotenje nabora praks ekološkega kmetovanja v integrirani pridelavi ("zeleno kmetovanje") v primerjavi s konvencionalno je bila v sezonah 2014-16 opravljena raziskava v Zahodni Bengaliji, Indija. Za pripravo tal je bil pri integrirani pridelavi uporabljen kompost skupaj z mineralnimi gnojili, pri ekološkem kmetovanju sta oskrba rastlin in nadzor škodljivcev sledila "Inhana" tehniki umnega kmetovanja (IRF). Raziskava je pokazala, da so bili večji pridelek (9.7 %), večja učinkovitost izrabe hranil in večja ekonomska vzdržnost doseženi pri integrirani pridelavi ne glede na mesto raziskave in sorto krompirja. Večje vrednosti kakovostnih kazalcev kot so vsebnost škroba, vitamina C, pH int. pri integrirani pridelavi bi lahko bile posledica ekološke obravnave rastlin, ki je ugodno vplivala na biokemične procese v rastlinah. Izboljšanje kakovosti tal, ki je bilo opaženo pri integrirani pridelavi, bi lahko bilo posledica uporabe na kmetijah pridelanega komposta, ki je vseboval bogato, samovzniklo mikrofloro (10 16 na enoto kolonije). Raziskava je pokazala, da lahko integrirana pridelava služi kot učinkovit nadomestek konvencionalnemu kmetovanju glede stalnosti pridelka, preprečevanja zastrupitve hrane in kakovosti končnih proizvodov preko večje uporabe obnovljive energije in vzpodbujanja fizioloških procesov v rastlinah.

“…The size of sample of stratifications was determined by Neyman technique. (Zangeneh et al, 2010;Yamane, 1967) The size of 383 orchards was considered as adequate sample size. To achieve the research objectives, the data required for this study were collected through questionnaire by the method of interview.…”
