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.

Restoration of soil has been identified as the option; to ensure crop sustainability. However, as per Trophobiosis Theory of French Scientist F. Chaboussou, focus on development of healthy plants is necessary to abate pest and disease invasion so as to ensure sustained crop performance, even under unfavorable environmental conditions. The present study, in randomized block design with green gram as test crop; was undertaken in Krishi Vigyan Kendra (Howrah, West Bengal) to evaluate the effectiveness of Inhana Rational Farming (IRF) Technology towards crop yield and soil quality development under different sustainable models viz. organic cultivation, integrated soil with organic crop management and non-chemical crop management; as compared to conventional farming practice. Highest yield was recorded under organic (933 kg ha ). The results were well corroborated with the plant development index obtained under these treatments. Favorable trend of soil quality under sustainable models especially in terms of microbial properties indicated the role of quality compost towards speedy rejuvenation of soil dynamics. The study indicated that reduction of synthetic fertilizers and qualitative management of soil is essential to restrict yield decline. However, plant management shall be prerequisite for ensuring crop sustainability without any time lag and under the changing climatic patterns. In this respect the potential of IRF Technology has been well accounted.

Native plant species have been the part of the local ecosystem and their contribution to fostering the wildlife and other living species is innumerable. However, the manicured landscapes in urban areas vastly boasts of the usage of exotic, introduced plant species in order to beautify them and as a consequence, there has been gradual depletion of native plant species of ornamental values. The commercial nurseries propagate plants which are in demand in landscaping business and hence, scope of conservation in mass scale is also fading. In such a situation, a review has been done about the practical scenario especially in Indian Context. It is undeniable that attempts are being taken in various parts of the world for revival of the native plant species, but not much awareness is observed in India. The Indian gardens are adorned with introduced plants along with very few native ones and the nurseries are propagating plants randomly without knowledge about their ecological significance and origin. Although, research and studies on identification of potential ornamental plants from wild is being done, it is focused in the Himalayas and Western Ghats of India. And not much work was found either on the revival of the native plants which are already established as ornamentals in the landscaped gardens or the newly identified wild species. Hence, there is scope for introduction of those native and wild plant species holding potential as ornamentals into the Indian landscaping scenario for the gain of both the species conservation as well as biodiversity restoration in the urban landscapes.
