“…The increase in dry matter production and the capture of solar radiation inside the canopy is closely associated with the rising LAI. Therefore, a decline in LAI is mirrored by a reduction in dry matter production 57 . In a similar vein, Dwyer and Stewart 58 found that crop light interception is significantly influenced by leaf area, which in turn has a significant impact on crop productivity.…”

“…The halt of vegetative development, the loss and senescence of leaves, and the reduction in LAI at later growth stages are the causes of the CGR decline after 55 DAS. These factors may have also decreased the photosynthetic efficiency and, eventually, the dry matter accumulation rate 57 . The CGR under KL 2 was reduced significantly compared to KL 1 in mung bean genotypes at different stages of life span.…”

Uneven rainfall and high temperature cause drought in tropical and subtropical regions which is a major challenge to cultivating summer mung bean. Potassium (K), a major essential nutrient of plants can alleviate water stress (WS) tolerance in plants. A field trial was executed under a rainout shelter with additional K fertilization including recommended K fertilizer (RKF) for relieving the harmful impact of drought in response to water use efficiency (WUE), growth, yield attributes, nutrient content, and yield of mung bean at the Regional Agricultural Research Station, BARI, Ishwardi, Pabna in two successive summer season of 2018 and 2019. Drought-tolerant genotype BMX-08010-2 (G1) and drought-susceptible cultivar BARI Mung-1 (G2) were grown by applying seven K fertilizer levels (KL) using a split-plot design with three replications, where mung bean genotypes were allotted in the main plots, and KL were assigned randomly in the sub-plots. A considerable variation was observed in the measured variables. Depending on the different applied KL and seed yield of mung bean, the water use efficiency (WUE) varied from 4.73 to 8.14 kg ha−1 mm−1. The treatment applying 125% more K with RKF (KL7) under WS gave the maximum WUE (8.14 kg ha−1 mm−1) obtaining a seed yield of 1093.60 kg ha−1. The treatment receiving only RKF under WS (KL2) provided the minimum WUE (4.73 kg ha−1 mm−1) attaining a seed yield of 825.17 kg ha−1. Results showed that various characteristics including nutrients (N, P, K, and S) content in stover and seed, total dry matter (TDM) in different growth stages, leaf area index (LAI), crop growth rate (CGR), root volume (RV), root density (RD), plant height, pod plant−1, pod length, seeds pod−1, seed weight, and seed yield in all pickings increased with increasing K levels, particularly noted with KL7. The highest grain yield (32.52%) was also obtained from KL7 compared to lower K with RKF. Overall, yield varied from 1410.37 kg ha−1 using 281 mm water (KL1; well-watered condition with RKF) to 825.17 kg ha−1 using 175 mm water (KL2). The results exhibited that the application of additional K improves the performance of all traits under WS conditions. Therefore, mung beans cultivating under WS requires additional K to diminish the negative effect of drought, and adequate use of K contributes to accomplishing sustainable productivity.

“…LAI reached to a maximum level at 50% flowering stage then decreased at a later growth stage (YCS and RiS), because of leaves shading. Hence, dry matter produced decreases with decreasing of LAI (Islam et al, 2017) and therefore has a large influence on crop yield (Dwyer and Stewart, 1986). Srivastava et al (2005) also reported that LAI was positively correlated with accumulated GDD in mustard.…”

“…The dry weight per unit of area was higher with 'BARI Sharisha-16' indicating the favorable response of biomass production. Islam et al (2017) reported that dry matter production by the plants depends on the amount of light energy interception by the leaves and its efficiency of conversion into chemical energy. Better dry matter production and its proper translocation into reproductive organ are the prime requisites of higher productivity of a crop (Ahmed et.al, 2010).…”

Thermal unit indices have a strong correlation with the phenology, growth and yield of crops and can be effectively used to select suitable crop cultivars for specific environmental conditions especially temperature. In this study, four mustard varieties (viz., 'BARI Sharisha-14', 'BARI Sharisha-15', 'BARI Sharisha-16' and 'Tori-7') were grown in two consecutive growing to assess the impact of thermal unit indices on crop growth and development, and to select the suitable variety for better yield under optimum sowing condition. Thermal unit indices viz., growing degree-day (GDD), helio-thermal units (HTU), phenothermal index (PTI) and heat use efficiency (HUE) were estimated from daily temperature and sunshine hours. Role of GDD on different growth indicators and seed yield (SY) were estimated through association and dependence of the traits. Significant variations in studied genotypes were observed for different traits. Among the studied varieties, 'BARI Sharisha-16' produced higher dry matter and seed yields (1.82 t ha-1) while accumulated maximum GDD at different growth stages. A strong positive association was obtained between GDD and the studied traits. Thermal unit indices had a strong influence in attaining different phenophases and other growth indicators. Therefore, results suggest that those indices could be used for growth prediction; further 'BARI Sharisha-16' is expected to use heat energy more efficiently for increasing the seed yields which indicated that the crop can perform better under global warming scenarios.

A field trial was conducted at the multi-location testing (MLT) site, Moulvibazar, Bangladesh during two consecutive years of 2017-2018 and 2018- 2019 located in Agro Ecological Zone (AEZ)-20; under Eastern Surma Kushiyara Floodplain to introduce maize in zero tillage as relay and after harvest of T. aman rice. Four sowing dates of maize seed viz. T1: 10 November as relay with T. aman rice, T2: 20 November as relay with T. aman rice, T3: 30 November in T. aman harvested fallow land and T4: 10 December in T. aman harvested fallow land were used as treatment variables. The trial was laid out in a randomized complete block design with three replications. Maize var. BARI Hybrid Maize-9 and short duration T. aman rice var. BRRI dhan56 /BRRI dhan57 were used. Sowing time is critical for maximizing yield for both grain and biomass yield of maize. Yield and yield attributes of maize varied significantly due to different sowing dates. The result showed that grain yields of maize 8.48, 11.20, 8.22 and 7.98 t ha-1 were achieved with seed sown on 10 November as relay with T. aman rice, 20 November as relay with T. aman rice, 30 November in T. aman harvested fallow land and 10 December in T. aman harvested fallow land, respectively. The highest grain yield (11.20 t ha-1) was obtained when sowing on 20 November as relay with T. aman rice, which showed an increase of grain yield of 40, 36 and 32 % than 10 December in T. aman harvested fallow land, 30 November in T. aman harvested fallow land and 10 November as relay with T. aman rice, respectively. The highest gross return (Tk. 2,30,095 ha-1), net return (Tk. 1,33,845 ha-1) and benefit cost ratio (2.39) were noted in the same treatment indicated the profitability of maize in zero tillage as relay with T. aman rice in AEZ 20.
