In the developing world, including Sub-Saharan Africa, reports have indicated that urban planning as a strategic instrument has not been able to guide urban spatial patterns and this poses challenges to improving urban environmental sustainability. The current study combined a city land use plan, Geographical Information Systems, and remotely sensed data to evaluate urban spatial patterns within areas where the city plan is reported to have been implemented to support strategic actions for urban environmental sustainability. Focusing on Abuja city, Nigeria, the study deployed a supervised classification on Landsat 8 remotely sensed data to analyze spatial patterns of urban land cover types, computed transition change detections and compared the urban impervious surface to the area of land designated for urban development by the city plan. Key findings indicated that the land areas designated for urban development have not been fully developed and the transition from urban green space is the highest transition from other land cover types to urban impervious surface. The baseline information provided in this study is crucial to inform decision-makers on improving and maintaining the implementation of strategic actions for urban environmental sustainability in Sub-Saharan African cities and other parts of the developing world.

Recently, sweet pepper (Capsicum spp.) has been a commercially important crop in Bangladesh. The cultivation procedure is highly sensitive to different environments. In the case of quality production, appropriate seedling age is a prerequisite for higher yield. The experiment was carried out at the Regional Horticulture Research Station, Bangladesh Agricultural Research Institute, Shibpur, Narsingdi, Bangladesh during the Rabi season of 2017-2018. Six treatments were used i.e.,. 14 days, 21 days, 28 days, 35 days, 42 days and 48 days at the age of transplanting seedlings. The experiment was conducted in a randomized complete block design with three replications. The number of seeds per fruit and thousand seeds weights resulted better at 21 days, 28 days and 35 days the age of transplanting seedlings. Considering marketable fruit number (13.55), yield per plant (1.69 kg) and yield (26.80 t ha-1) was found at 28 days’ age of transplant seedling, which was followed by 35 days’ age of transplant seedling. The lowest yield per plant (0.49 kg) and yield (7.76 t ha-1) were recorded at 48 days age of transplant seedling, respectively. From the result of this experiment, it may be recommended that 28 days’ age of seedling at transplant growth, yield and seed production showed better performance than other ages of seedlings at transplants of BARI Mistimorich-1.
最近，甜椒(Capsicum spp.)在孟加拉国已经成为一种重要的商业作物。栽培过程对不同环境高度敏感。在优质生产的情况下，适当的苗龄是提高产量的先决条件。该试验于2017-2018年拉比季节在孟加拉国纳辛格迪Shibpur的孟加拉国农业研究所区域园艺研究站进行。采用了六种处理方法，即。移栽苗龄14天、21天、28天、35天、42天和48天。试验采用完全随机区组设计，设3个重复。在移栽苗龄21、28和35 d时，单果种子数和千粒重较好。以可售果数(13.55个)计算，移栽28日龄时单株产量(1.69 kg)和产量(26.80 t hm -1)，移栽35日龄次之。移栽苗龄48 d时单株产量最低(0.49 kg)，单株产量最低(7.76 t hm -1)。从本试验结果可以看出，BARI Mistimorich-1移栽28日龄的幼苗生长、产量和制种性能均优于移栽其他年龄的幼苗。

The experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, to explore the growth and yield performance of boro rice cv. BRRI dhan28 is influenced by foliar spray of potassium nitrate (KNO3) at four rice growth stages. The experiment consisted of four doses of KNO3 viz. 0 (Control), 0.25, 0.50 and 1.00 kg ha−1 and applied at four growth stages of rice development viz. at panicle initiation, at ear emergence, at anthesis period and at dough stage. This experiment was carried out in Randomized Complete Block Design (RCBD) with three replications with 10 m2 (4.0 m × 2.5 m) unit plot size and spacing between blocks and unit plots was 1 m and 0.5 m, respectively. Results revealed that foliar application of potassium nitrate at four growth stages significantly affected yield and yield contributing characters of BRRI dhan28. But most of the yield contributing characters did not differ significantly due to the interaction between potassium nitrate and stage of foliar spray. However, the foliar application of KNO3 @ 0.25 kg ha−1 showed the highest yield production (5.86 kg ha−1) while the lowest yield (4.85 kg ha−1) was found in control. Furthermore, better yield performances were recorded when the KNO3 was applied at panicle initiation stage rather than the other four growth stages. The total number of tillers, 1000–grain weight and grain yield, was higher with foliar spraying of a 0.25 kg ha−1 KNO3 at panicle initiation stage. From this experiment, it may be concluded that foliar application of KNO3 affected the yield performances of BRRI dhan28 and 0.25 kg ha−1 KNO3 produced the highest grain yield when applied at panicle initiation stage of boro rice.
该试验在孟加拉国农业大学Mymensingh农学田间实验室进行，旨在探索米罗稻cv的生长和产量性能。水稻4个生育期叶面喷施硝酸钾对BRRI dhan28的影响。试验采用4个剂量的KNO3，分别为0(对照)、0.25、0.50和1.00 kg ha - 1，分别施用于水稻穗发育期、出穗期、开花期和成粒期。试验采用随机完全区组设计(RCBD)， 3个重复，小区面积为10 m2 (4.0 m × 2.5 m)，小区间距为1 m和0.5 m。结果表明，4个生育期叶面施用硝酸钾对BRRI dhan28的产量和产量贡献性状均有显著影响。但由于叶面喷施阶段和硝酸钾的交互作用，大部分产量贡献性状差异不显著。然而，叶面施用KNO3 @ 0.25 kg ha - 1的产量最高(5.86 kg ha - 1)，而对照产量最低(4.85 kg ha - 1)。此外，在穗初期施用KNO3比在其他4个生育期施用效果更好。穗初叶面喷施0.25 kg ha - 1 KNO3可提高分蘖总数、千粒重和籽粒产量。本试验结果表明，叶面施用KNO3影响BRRI dhan28的产量表现，在水稻穗初施用0.25 kg ha - 1 KNO3产量最高。

The green chemistry movement has aimed to make the sector safer and more competitive over the last two decades. Yet mindset is evolving gradually, and the transition still has a long and challenging path ahead. Green Chemistry is a revolutionary philosophy that began 20 years ago and aims to unify government, academic and industrial societies. Through making the early stages of innovation and development, more focus on environmental impacts and addressing through green chemistry could be a viable alternative to protect our environment and reduce industrial emissions. In this review article, we will discuss the green chemistry as ecofriendly chemistry. This review also synthesis the foundation, principals and future directions of green chemistry.
