SUMMARYContinuous rice–wheat (RW) cropping in an area of 13.5 million ha with intensive tillage has resulted in over exploitation of resources, decline of the factor productivity, loss of soil fertility and biodiversity and decline of resource use efficiency in the Indo-Gangetic plains (IGPs) of South Asia. This has led to unsustainability of agriculture in the region. Replacement of a cereal-cereal system with a legume–cereal system may prove beneficial for long-term sustainability of the system. A field experiment was conducted with soybean–wheat (SW) rotation in the IGP of India during 2009–10 and 2010–11 to assess the suitability of conservation tillage versus conventional tillage (CT) and crop-establishment techniques, namely bed (B) planting versus flat (F) planting. The study revealed that the zero tillage (ZT) for soybean during rainy and for wheat during winter season either in flat or in bed system performed equally good with CT. The maximum system productivity (7.06 t ha−1 in 2009–10 and 8.48 t ha−1 in 2010–11) was obtained with combined application of wheat + soybean residue. The maximum net returns of ₹46.98 and ₹65.08 thousands and B:C ratio of 2.35 and 3.08 were recorded in the SW system with zero tillage-flat (ZT─F) during 2009–10 and 2010–11, respectively. The minimum energy of 64.67 and 63.01 ×103 MJ ha−1 was utilized as input energy with zero tillage-bed (ZT─B) while the maximum energy use efficiency of 4.10 and 5.14 was obtained with ZT─F and ZT─B for the SW system during 2009–10 and 2010–11 respectively. The gross output energy was maximum with wheat + soybean residue (241.6 and 265.7 ×103 MJ ha−1) contrary to this the net energy (194.4 and 213.4 ×103 MJ ha−1) and energy use efficiency (9.03 and 10.96) was maximum with control (no residue) in the SW system. In wheat there was 37.85% improvement in irrigation water use efficiency (WUE) in raised bed planting than flat planting and 28.57% of irrigation water was saved. The study suggested that ZT either bed or flat planting to both the crops can successfully adopted along with application wheat + soybean residue together with full recommended dose of NPK fertilizers to the system for improving productivity, profitability, soil health and sustainability of SW system in the IGPs of South Asia.

Residue Retention

Field experiments were conducted to evaluate conventional tillage (CT), permanent raised bed (PRB), and zero tillage (ZT) with residue retention and removal at three nitrogen levels (0, 100, and 120 kg N ha-1) on wheat productivity, energy input and energy output, energy use efficiency, specific energy, and CO2 emission from 2010 to 2012 under rice-wheat system at Pheta V.D.C, Bara, Nepal. The experiments were carried out in strip split plot designs with three replications. Zero tillage wheat produced significantly higher grain yield (2616.5 kg ha-1), saved 10.4 % energy input, increased energy output (12.4 %), enhancing energy use efficiency by 25.2 % and reducing specific energy by 23.6 %, as compared to conventional tillage. Diesel consumption on crop establishment and irrigations were the lowest for ZT (48.6 liter ha-1) and the highest for CT (86.3 liter ha-1). PRB consumed the lowest quantity of diesel on two irrigations (34.6 liter ha-1) with higher energy use efficiency (3.4 %) and lower specific energy (8.76 MJ kg-1) over CT. The CO2 emission from CT was the highest (224.32 kg ha-1) over ZT (126.4 kg ha-1) and PRB (146.11 kg ha-1). Residue retention increased 4 % grain yield over residue removal. Without nitrogen application, energy output was the lowest (34192 MJ ha-1) with the highest specific energy (12.6 MJ kg-1). Thus, zero-till wheat with 40-cm residue retention and 100 kg N ha-1 application was suggested for mass scale adoption in the Tarai region of Nepal.DOI: http://dx.doi.org/njst.v15i2.12104      Nepal Journal of Science and Technology Vol. 15, No.2 (2014) 1-10

A field experiment was conducted at Imphal, Manipur during 2010-12 to study the effect of liming, planting time and tillage on system productivity, resource use efficiency and energy dynamics of rice (Oryza sativa L.) - lathyrus (Lathyrus sativus L.) cropping system. The experiment was laid out in split plot design with 3 replications. The treatment consisted of two factors i.e. liming (liming and no liming) and planting time (early and normal) given to rice crop during kharif season in the main plots and two tillage practices (no tillage and conventional tillage) were given in the succeeding lathyrus crop during the rabi season in the sub plots. Results showed that application of lime @ 500 kg CaCO3/ha before planting rice improved system productivity marginally in terms of rice-equivalent yield (REY of 6.32 t/ha) and water use efficiency (WUE) of the system (20.51 kg/ha-mm), however, it failed to increase benefit: cost (B: C) ratio. Advancing planting time of rice 15 days ahead of normal planting enhanced growth and yield of succeeding lathyrus crop resulting in increase of REY, land use efficiency (LUE), production efficiency (PE), and partial factor productivity (PFP) of the system by 19.3, 1.7, 17.0 and 17.0 %, respectively and moreover, it recorded higher system B:C ratio (1.20). No tillage enhanced PFP, NUE, WUE and B: C ratio of the system, while conventional tillage increased energy consumption by 9.45 %.

Resource use efficiency is a critical issue for a competitive and sustainable economic activity. Indeed, resource use efficiency implies both economic and environmental consequences. Therefore, a sustainable rural development policy is required to promote resource use efficiency. In order to identify the prospective directions for strategic management of the resource in Lithuanian agricultural sector, the trends of the resource use therein are to be identified. The aim of the present paper is to analyse the trends of the resource use in Lithuanian agricultural sector and thus identify the most problematic areas. The concept of decoupling is used to describe the underlying changes in the resource use. The World Input-Output Database (WIOD) is applied for the analysis. The research focuses on energy use, land use, material extraction and carbon emission from the agricultural sector. The results show that the period of 1995–2009 was specific with weak (relative) decoupling of the material extraction from the economic activity and expansive negative decoupling of the use of water resources from the economic activity.

Abstract LED lighting in indoor farming systems allows to modulate the spectrum to fit plant needs. Red (R) and blue (B) lights are often used, being highly active for photosynthesis. The effect of R and B spectral components on lettuce plant physiology and biochemistry and resource use efficiency were studied. Five red:blue (RB) ratios (0.5-1-2-3-4) supplied by LED and a fluorescent control (RB = 1) were tested in six experiments in controlled conditions (PPFD = 215 μmol m−2 s−1, daylength 16 h). LED lighting increased yield (1.6 folds) and energy use efficiency (2.8 folds) as compared with fluorescent lamps. Adoption of RB = 3 maximised yield (by 2 folds as compared with RB = 0.5), also increasing leaf chlorophyll and flavonoids concentrations and the uptake of nitrogen, phosphorus, potassium and magnesium. As the red portion of the spectrum increased, photosystem II quantum efficiency decreased but transpiration decreased more rapidly, resulting in increased water use efficiency up to RB = 3 (75 g FW L−1 H2O). The transpiration decrease was accompanied by lower stomatal conductance, which was associated to lower stomatal density, despite an increased stomatal size. Both energy and land surface use efficiency were highest at RB ≥ 3. We hereby suggest a RB ratio of 3 for sustainable indoor lettuce cultivation.

Background: Conservation agriculture (CA), an agricultural production system with optimum inputs, high returns and sustainability while conserving environment is primarily required for command areas and rainfed uplands. CA helps to improve and conserve soil health through crop rotation, mulching, minimum field traffic and mechanical soil disturbance etc and conserve water to achieve economically and ecologically sustainable crop production. Methods: The field experiment was conducted for two years during 2019-21 to evaluate the influence of conservation agricultural practices on the system productivity, production efficiency and energy use under legume based cropping system in a command area. Treatments comprised of four cropping systems as Groundnut - foxtail millet (C1), Groundnut - barnyard millet (C2), Daincha - foxtail millet (C3) and Daincha - barn yard millet (C4) in main plots and foliar application of organics, 3% panchagavya, 1% PPFM and 0.1% humic acid formed subplots. Result: System productivity in terms of Groundnut equivalent yield (GEY) was significantly higher (8395 kg/ha) in the Groundnut - Barnyard millet cropping system with foliar application of PPFM 1% in CA system than that of conventional method. The production efficiency was maximum in Groundnut - barnyard millet system (34.41 kg/ha/day) and Groundnut - foxtail millet recorded the highest energy use efficiency (6.8%) which shows that maximum energy was effectively utilized under the system. Daincha - foxtail millet system had highest energy productivity of 0.91 kg M/J. Thus, the conservation tillage based Groundnut - barnyard millet system recorded more system productivity, highest resource use efficiency (both production and land use efficiency) and the highest energy use efficiency.

A field experiment was conducted at Instructional Farm of ICAR- Krishi Vigyan Kendra, Tura during kharif, pre-rabi and rabi season of 2011-12 to 2013-14 to determine the suitable production potential, profitability, resource use efficiency and sustainability of diversified maize-legumes cropping system. The five cropping sequences viz., CS1: Maize + Blackgram (1:2) – green gram + maize (2:1) – tomato, CS2: maize + green gram(1:2) – green gram + maize (2:1) – tomato, CS3: maize + groundnut(1:2) – green gram + maize (2:1) – tomato, CS4: maize + Ssybean(1:2) – tomato and CS5: maize sole – green gram – tomato were replicated four times using a randomized block design on sandy loam soil with low to medium fertility level and slightly acidic in reaction. The cropping system “Maize + Green gram(1:2) – green gram + maize (1:1) – tomato” was found to be most remunerative and sustainable with system productivity (175.49 q/ha), net return (Rs.3,38,725/ha), profitability (Rs. 928.01 /ha/day), benefit cost ratio (4.40), sustainable yield index (1.00), production efficiency (Rs.58.30/ha/day), relative economic efficiency (162.72%), except land use efficiency(LUE) which was the highest (85.75%) in “maize + groundnut(1:2) – green gram + maize (1:1) – tomato” cropping system. The lowest system productivity, net returns, profitability, production efficiency, land use efficiency etc was found in maize+ soybean (1:2)- tomato followed by maize-greengram-tomato cropping system. Hence, the cropping sequence maize + green gram(1:2) – green gram + maize (1:1) – tomato and maize + groundnut(1:2) – green gram + maize (1:1) – tomato were found to be the productive, profitable, remunerative, resource use efficient and sustainable in the mid hills sub-tropical regions of India.

The field experiments were conducted at Agricultural Research Station, Hukkeri, Belagavi, Karnataka, India during 2018–19 and 2019–20 to study the system productivity and resource use efficiency of alternative cropping systems for sugarcane. There were 11 treatments involving different cropping systems viz., soybean–sorghum–ridge gourd, pigeon pea±green gram (1:1)–beans, pigeon pea±soybean (1:1)–cowpea, soybean–wheat–groundnut, groundnut–sorghum–sesame, maize–cabbage–fallow, soybean–wheat–green gram, maize–wheat–sesame, Bt cotton–groundnut, sugarcane±onion (1:2) and sugarcane (sole) replicated thrice and laid out in randomized complete block design. Among the cropping systems, maize-cabbage-fallow system recorded significantly higher total system productivity (58,234 kg ha-1), water use efficiency (199.67 kg ha-1-mm) and energy use efficiency (129.91 MJ ha-1) compared to rest of the cropping systems. However, sugarcane (sole) recorded (1,11,008 kg ha-1, 68.64 kg ha-1-mm and 16.58 MJ ha-1, respectively). Based on alternative cropping systems involving only field crops, maize-wheat-sesame (9633 kg ha-1, 30.65 kg ha-1-mm and 132.20 MJ ha-1, respectively), soybean-wheat-groundnut (7602 kg ha-1, 27.40 kg ha-1-mm and 32.35 MJ ha-1,, respectively), soybean-wheat-green gram (6424 kg ha-1, 23.05 kg ha-1-mm and 31.91 MJ ha-1, respectively) and Bt cotton-groundnut (4503 kg ha-1, 17.97 kg ha-1-mm and 16.95 MJ ha-1, respectively) were significantly higher. By adopting the alternative cropping systems, there was water saving of approximately 45% compared to sugarcane monocropping and sugarcane±onion (1:2) intercropping.
