Frontline demonstration on potato (Kufri Sindhuri) was conducted by Krishi Vigyan Kendra, East Sikkim, India. A total 158 nos. of demonstration were conducted in rice-fallow (farmers’ practice) at farmer’s field in nine numbers of villages during the year 2019-20. Results revealed that average yield of rice and potato recorded was 2.09 t/ha and 14.13 t/ha, respectively. Higher system rice equivalent yield (REY) was recorded 16.22 t/ha in rice-potato and 2.1 t/ha and rice-fallow system. System production efficiency (SPE) was also higher in rice-potato (62.14 kg/ha/day) as compared to rice-fallow (14.51 kg/ha/day). Land use efficiency (LUE) was recorded 71.51 % and 39.45 % in rice-potato and rice-fallow system, respectively. Net return was found Rs.16032/ha in rice-fallow and Rs.183952/- with rice-potato system during the years of demonstration. Higher benefit to cost (B: C) ratio was found 2.82:1 in rice-potato than in rice-fallow (1.62:1) system. Economic efficiency was also recorded higher in rice -potato (704.80 Rs/ha/day) than rice-fallow (111.33 Rs/ha/day) during the demonstrated year. Hence, it may be concluded that the inclusion of potato in rice -fallow is an option for increasing the additional income of the farmers for their livelihood improvement.

Changing three crops pattern to four crops can play a potential role for achieving countries food security. With this view to increase crop productivity, production efficiency, land use efficiency, and economic return through intensifying cropping intensity as well as crop diversity by transforming three crops pattern to four crops, the experiment was conducted in High Ganges River Floodplain Soils under the Agro-Ecological Zone (AEZ) 11 at Pali, Durgapur, under the Multilocation Testing Site, Puthia, Rajshahi, for two consecutive years 2014-15 and 2015-16. Four crops pattern mustard-onion/maize-T. Aman rice was tested at on-farm condition over the existing three crops pattern mustard-onion-T. Aman rice. Maize was introduced here as a relay crop with onion to fit it in the four crops pattern. The experiment was laid out in RCB design with six dispersed replications. Two-year crop cycles were completed, and data regarding component crops yield were considered for assessing the performance of the two cropping patterns for making a sense of comparing productivity. Although there was no significant difference in component crops yield between four crops and three crops pattern, as an additional crop, maize tremendously increased the system productivity and economic return of the four crops pattern. Higher rice equivalent yield 28.96 t·ha−1 in 2013-14 and 30.95 t·ha−1 in 2014-15 was recorded from the four crops pattern with a mean rice equivalent yield (REY) 29.95 t·ha−1 over the existing pattern with a mean value 21.76 t·ha−1. However, four crops pattern resulted in higher cultivation cost due to growing maize as an additional crop; nevertheless, it gave the higher gross return, marginal return, marginal benefit cost ratio, and production efficiency. The four crops pattern resulted averagely 37.63% higher production (REY) compared to the existing three crops pattern. Production as well as land use efficiency were increased by 9.33% and 19.18%, respectively, from the intensified alternate pattern.

The experiment was conducted at the farmers field of FSRD site, Elenga and MLT site Modhupur, Tangail during two consecutive years 2011-12 and 2012- 13 to study the productivity, production efficiency, land use efficiency and economic return of the improved cropping pattern (Mustard - Boro - Jute -T. Aman) against the existing cropping pattern (Mustard -Boro - T. Aman) through incorporating of modern crop varieties and improved management practices. The experiment was laid out in randomized complete block design with six dispersed replications. The pooled data of improved management practice for the pattern produced significantly higher yield in Mustard and T. Aman rice respectively and also gave additional jute yield. The gross return and gross margin were higher in improved pattern compared to that of existing farmer’s pattern with only 149 and 151% extra cost at FSRD site, Elenga and MLT site Modhupur, respectively. The higher benefit cost ratio (1.74 and 1.79), rice equivalent yield (22.41 and 21.82), production efficiency (40.19 and 39.48) and land-use efficiency (95.75 and 96.48) indicated the superiority of the improved pattern over the farmer’s existing pattern at both sites. Higher rice equivalent yield indicates that improved cropping pattern (Mustard - Boro - Jute -T. Aman) could be suitable in Tangail region for increasing crop productivity as well as cropping intensity.Bangladesh J. Agril. Res. 40(2): 259-270 June 2015

Intercropping provides opportunity to harness available resources. Thus, maize intercropped with soybean or peanut (groundnut) was tested with 1 : 1, 1 : 2, and 1 : 5 row proportions along with sole plantings of each crop to measure resource capture and resource-use efficiency. Results revealed that sole peanut had 60% higher maize-equivalent yield and 55% better production efficiency, followed by the 1 : 5 row proportion of maize–peanut, over sole maize. Intercropping increased land-use efficiency by 17–53% and land-equivalent coefficient by 0.21–0.56. The relative crowding coefficient was 39% higher with 1 : 2 maize–soybean, whereas the monetary advantage index was the highest (US$107) with the 1 : 5 maize–peanut. Nitrogen (N) and potassium (K) uptakes by maize were 42.9% and 38.2%, respectively, higher with 1 : 5 maize–soybean, whereas phosphorus (P) uptake was 64% higher with 1 : 5 maize–peanut. However, the least amounts of N, P and K were mined overall with 1 : 5 of maize–soybean. Soil moisture content was improved by 24% and solar radiation interception by 37.8% with soybean alone over maize alone, and these parameters increased with higher row proportions of soybean. The energy parameters also improved with the 1 : 5 row proportions of maize–soybean or peanut intercropping. This study provides a basis for efficient resource use by maize–soybean (or peanut) intercropping system.

Inclusion of mungbean in a cropping pattern not only increases the cropping intensity but also enriches soil health as well as ensures nutrition for the fast-growing population of Bangladesh. A study was conducted in farmers’ field of Domar, Nilphamari, Bangladesh during 2013-14 and 2014-15 to evaluate the performance of four-crop based cropping pattern Potato – Mungbean – Jute - T.Aman rice against the existing farmer’s pattern Potato-Jute-T.Aman rice. The experiment was laid out in randomized complete block design with six disperse replications. Two-year study revealed that inclusion of mungbean and practice of better management along with use of modern high yielding varieties in the existing cropping pattern increased rice equivalent yield of the whole pattern by 38.7% and economic profit by 73.1%. Moreover, land use efficiency and production efficiency of Potato – Mungbean – Jute -T.Aman pattern were higher than the existing pattern by 14.0 and 28.2%, respectively. Thus, the study suggests incorporation of mungbean in the existing Potato-Jute-T.Aman pattern could be a agronomically and economically profitable for the farmers as well as cropping intensity can be increased.Bangladesh Agron.

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.

Intercropping increases land use efficiency and provide prolonged yields between compatible crops. A study was conducted to evaluate the yield advantage of intercropping southernpeas (Vigna unguiculata) with corn (Zea mays) in addition to determining the yield advantage of corn, `Yellow Trucker', and two southernpeas cultivars; `Mississippi Silver' and `Pinkeye Purolehull', in an intercrop. Cropping method significantly affected the yield of corn but not southernpeas. Cropping method also influenced leaf area, dry matter and plant height of both southernpeas cultivars. Corn had higher yields in alternate-single row (45×30 cm) with southernpeas intercrop than within (90×15 cm) or alternate row (90×15). Competition for light and nutrients may have accounted for the reduction in dry matter and leaf area of southernpeas in intercrop. The average yield advantage, as measured by the land equivalent ratio, ranged between 1.39 and 1.70. When area time equivalent ratio was used to measure the yield advantage, the range was 1.2 to 1.45. `Pinkeye Purplehull' is more compatible with corn in intercropping than `Mississippi Silver'.

A study was conducted for two consecutive years to determine the yield and system productivity of two cropping patterns viz. IP: (Wheat - Jute - T. aman) improved pattern with improved management practices and FP: (Fallow - Fallow - T. aman) farmers’ pattern with farmers’ management practices in char (adjacent to the river) area of Netrakona region of Bangladesh. The experimentswere laid out in a randomized complete block design with 10 dispersed replications at a farmer’s field. The two years mean data showed that the total component crops of IP (wheat-jute-T. aman rice) gave higher yield as well as a by-product in both years. The higherrice equivalent yield (10.52 and 10.63 tha-1), production efficiency (30.13 and 30.43 kg ha-1 day-1) land-use efficiency (87.13 and 87.84%)and benefit cost ratio (2.15 and 2.11) pointed out the dominance of the improvedpattern over the farmer’s existing pattern. Higher rice equivalentyield signified that improved cropping pattern (Wheat - Jute -T. aman) could be appropriate in Netrakona region for rising crop productivity andcropping intensity.The higher production efficiency, land use efficiency and benefit cost ratio indicated the superiority of the improved pattern over the farmers’ practices.It can be concluded that farmers of the char area of the Netrakona region might follow wheat (var. BARI Gom-26) - jute (var. O-9897) - T. aman (var. BRRI dhan49) cropping system in char land for higher productivity and profitability.

Development Orientation

Rapid urbanization has provided a strong impetus for the economic growth of China, but it has also caused many problems such as inefficient urban land use and environmental pollution. With the popularization of the concept of green and sustainable development, the Environmental-Social-Governance (ESG) assessment concept is widely accepted. The government and residents are paying more and more attention to environmental issues in urban development, and environmental protection has formed an important part of urban development. In this context, this study takes 26 cities in the Yangtze River Delta as examples to build an evaluation system for urban land-use efficiency under green development orientation. The evaluation system takes into account the inputs of land, capital, labor, and energy factors in the process of urban development. Based on emphasizing economic output, the social benefits and undesired outputs brought about by urban development are taken into account. This paper measures urban land use efficiency by the super-efficiency SBM model, and on this basis, analyses the spatial-temporal evolution characteristics of urban land-use efficiency. Further, this paper measures urban land use efficiency without considering undesired outputs and compares the two evaluation methods. Again, the comparison illustrates the rationality of urban land use efficiency evaluation system under green development orientation.

The Impact

The construction and operation of high-speed rail (HSR) has become an important policy for China to achieve efficiency and fairness and promote high-quality economic growth. HSR promotes the flow of production factors such as labor and capital and affects economic growth, and may further affect urban land use efficiency (ULUE). To explore the impact of HSR on ULUE, this paper uses panel data of 284 cities in China from 2005 to 2018, and constructs Propensity Score Matching-Differences in Differences model to evaluate the effect of HSR on ULUE. The result of entire China demonstrates that the HSR could significantly improves the ULUE. Meanwhile, this paper also considers the heterogeneity of results caused by geographic location, urban levels and scales. It demonstrates that the HSR has a significantly positive effect on ULUE of Eastern, Central China, and large-sized cities. However, in Western China, in medium-sized, and small-sized cities, the impact of HSR on ULUE is not significant. This paper concludes that construction and operation of HSR should be linked to urban development planning and land use planning. Meanwhile, the cities with different geographical locations and scales should take advantage of HSR to improve ULUE and promote urban coordinated development.
