“…The results of a long-term experiment (33 years) confirmed that the negative net carbon balance in the fields adversely affected, consequently deteriorated soil health due only to chemical fertilizer dependent nutrient management for rice crops in Bangladesh. As a result, soil of about 40% of the net cropped area of the country is under health risk (Haque et al, 2019). The incorporation of (i) 20 cm of rice straw into the soils of the rice-rice cropping patterns, (ii) Sesbania (S. rostrata) cultivation during the fallow period and incorporation into the soil, and (iii) increased application of organic fertilizers (such as, kitchen waste) and farmyard manure in the crop fields may reduce soil health risk (Details in Haque et al 2020).…”

Built on deep-rooted political and cultural heritage, ‘rice security’ is the foundation of ‘food security’ in Bangladesh. The country has been in production-surplus of rice in the current decade feeding over 165 million people. This on-going ‘selfsufficiency momentum’ would require to maintain to meet increased demand from growing future population. On developmental side, Bangladesh is placed among the three of the world’s fastest growing economies in the years through to 2050. Rice sector would need to match with the pace of this growth. In addition, agriculture sector, that includes rice, is to double the productivity as the government commits to meet the SDG goal 2.3.1. This study addresses those issues through scoping increased rice production and productivity in Bangladesh, developing a plan of work (POW) on translating the scope and designing implementation plans and actions, incorporating efficiency, resilience, stability and sustainability issues, to achieve the POW. The study has used brainstorming, and rigorous analysis to achieve the objectives. The productivity has been explained in terms of yield- and labour-productivity. The developed three-winged ‘doubling rice productivity (DRP)’ framework directs yield enhancement and production accumulation in unexplored spaces (Wing-1); increased adoption of mechanization to impact on labour productivity (Wing-2), and improvements in nutritional quality and rice-based product diversity, and stabilizing the farmgate price (Wing-3). Analyses show, from the baseline figure of 35.29 MT in 2015, rice production in the country can be raised to 46.90 MT in 2030, 54.09 MT in 2040 and 60.85 MT in 2050 with combined contributions of three pillars – yield improvements by enhanced varietal potential (Pillar 1), reduction in existing yield gap (Pillar 2) and production increase by exploring unexplored spaces for rice (Pillar 3) of Wing-1 of the DRP. This production will produce a surplus of 6.50, 10.29 and 13.65 MT in 2030, 2040 and 2050, respectively, over the production target (40.40, 43.80 and 47.20 MT in 2030 and 2050, respectively). Results further reveal that through scale-appropriate mechanization backed up by estimated fair price, labour productivity in rice will be doubled by 2029, meeting the SDG 2.3.1. Good number of released varieties have been identified to have specific nutritional trait, and value adding quality. We have emphasized on much needed actions on demand-driven research for varietal development and field-adoptable management, mechanization for transplanting and harvesting operations, accommodation of rice in unexplored spaces, farmer-based speedy seed multiplication and dissemination system, establishment of commission for agricultural costs and prices, input buffer stock terminals for managing production risk, long-term storage and export of surplus production, and research-publicity-market development for rice-based products through public-private partnership. It is concluded that efficiency, resilience and sustainability around the three wings of DRP in the rice production systems to be ensured to achieve the rice production, productivity and labour use estimates.

“…The experiment was initiated on a permanent layout at the BRRI farm, Gazipur, Bangladesh in 1985. Twelve treatments in randomized complete block design (RCB design) with four replications were imposed (Haque et al, 2019a). However, we have considered only NPKSZn, PKSZn (-N), NKSZn (-P), NPSZn (-K), NPKZn (-S), NPKS (-Zn) and control treatments for our analyses and interpretations of findings.…”

“…Excessive or inappropriate use of chemical, among others, fertilizers is a major cause of nutrient imbalance in soil. Continuous rice culture using sole chemical fertilizer reduces soil quality, carbon sequestration and rice productivity (Haque et al, 2019a, c). In such situations, chemical and organic nutrient sources and agronomic management system could be important management options to improve rice productivity and soil quality (Timsina, 2006 andSihi et al, 2017).…”

“…The continuous chemical and imbalanced fertilization are considered to be the main issue of rice productivity decline in Bangladesh (Saleque et al, 2004). Rice productivity trends were declining in many long-term fertilization experiments under double rice cultures and also in non-rice based double or triple cropping systems (Haque et al, 2019a, 2015band Yadvinder et al, 2005. Rice-Fallow-Rice is the most dominant cropping pattern in Bangladesh covering about 27% of the cropland (Nasim et al, 2017).…”

Nutrient management influences soil health and crop productivity. Sustained crop production re-quires specific nutrient management options after a certain period. The objectives of this investigation were to examine the effects of inorganic and organic fertilization on yields and soil carbon budget under rice based cropping patterns in Bangladesh. The research data and informationhave been gen-erated based on previouslypublished, unpublished sources and own concept.Omission of K or im-balanced K are more influential for reduction in grain yield up to 47% in Boro (dry) season but N was most limiting up to 35% in T. Aman (wet) season. With existing fertilizer rates for growing rice, the balances of N and K are always negative. Balanced chemical fertilizer (NPKSZn) can be an option for improving crop productivity and maintain soil quality. Net ecosystem carbon (C) balances are posi-tive when 3 t ha-1 cow dung (CD), 2 t ha-1 poultry manure (PM) and 2 t ha-1 vermicompost (VC) are used in combination with chemical fertilizers. Soil amendments with organic nutrient sources (rice straw, CD, PM, VC, legume crops) and rice based cropping patterns such as T. Aman-Mustard-Boro, Boro-Fallow-Fallow, Jute-T. Aman-Fallow, Wheat-Mungbean-T. Aman, Grass pea- T. Aus-T. Aman and Potato-Boro-T. Aman can be beneficial in improving soil C budget, soil nutrient ratio, total crop production and maintenance of environmental health that will meet SDGs goal.

“…Moreover, the production of cereals is decreasing in many areas because of climate change (CC) impacts [3]. Soil productivity is declining with continuous chemical fertilizers use [4] along with decreased freshwater availability for agricultural production and thus a challenge of sustainable crop production [5]. It is estimated that agricultural systems in the world are losing about 75 billion tons of fertile soils each year [6].…”

Different kinds of cereals are the dominant carbohydrate source for the global population of which minor cereals, a group of neglected crops, play an important role in proving substitute of rice or wheat in the harsh environment of the globe. These crops have been replaced in many areas with the advent of irrigation facilities, availability of modern crop varieties and improvement of fertilizer management systems. In the present investigation, we have delineated production zones and established relationships of minor cereal cultivation with selected social character and future climatic conditions based on existing literature and survey data. In most cases, six minor cereals are cultivated in Bangladesh. Panicum miliaceum and Setaria italic cover larger areas and are mainly grown in north, north-west, central parts and hilly regions of the country and provide 400-1500 kg ha-1 grain yield. Although low grain yields, farmers having 0.2-0.8 ha land holdings mostly cultivate minor cereals because of its high profit within a short period of time, can be grown in poor soil and does not require special care. Besides, the product can be utilized in different ways, such as food and feed with social aristocracy. Because of climate change impacts, the optimum temperature windows for studying minor cereals will be narrowed down to 15 November through 15 February by 2050 although the critical maximum temperature range might not be a problem for growing minor cereals in Bangladesh. If high-yielding varieties of minor cereals are available, it would be a climate-smart technology in the future.
