“…Irrespective of treatments, inter-year variation in seed yield might be attributed to the fluctuation in atmospheric conditions, especially with respect to the duration of bright sunshine between 2020 and 2021 during different phenophases of the crops. The results are in line with the observations of Kaisher et al [56], Kataria et al [40], and Iram et al [36] in green gram and of Math et al [57] in black gram. Interaction effects of all the three factors on both dry matter accumulation and seed yield were statistically significant in the maximum cases (Table 11).…”

The thermal environment of a crop is one of the prime factors enhancing growth and production by regulating its physiological processes at different phenophases. To study the impact of thermal regime on spring–summer-grown black gram (variety Pant Urd 31), an experiment was conducted with different sowing dates (from the first to the third week of March), soil application of cobalt (Co) and foliar sprays of potassium (K) and boron (B) in various combinations in the split–split plot design during 2020 and 2021. The first-week-of-March-sown crop recorded more accumulated growing degree-days (GDD), photothermal units (PTU) and heliothermal units (HTU) with a longer duration than the later sown crop. Higher daily mean temperature during the reproductive stage of the later sown crop compelled it to complete the phenophases earlier than the normally sown crop, leading to yield reduction. Soil application of Co at 4 kg ha−1 and foliar sprays of K at 1.25% and B at 0.2% mitigated the adversities of excess heat irrespective of sowing dates. Variations in GDD and HTU, respectively, explained variations of about 75.8% and 87.3% in the final dry matter accumulation and of 72.9% and 84.8% in seed yield through polynomial regressions in the respective years. The maximum mean thermal use efficiency (TUE) for biomass production (0.24 g m−2/°C/day−1) and seed yield (0.11 g m−2/°C/day−1) were observed with Co soil application and combined foliar sprays of K and B due to higher dry matter production or seed yield with lower heat units accumulation in the first sown crop.

“…Additionally because of stress, the crop faced adverse impacts on its CGR and LAI, consequently acquiring lesser photosynthetic area and biomass production, hampering seed set and yield potential [73]. This finding resembled the observations of Math et al [22] in black gram and Kataria et al [29] and Iram et al [25] in the case of green gram.…”

“…A good number of research efforts have revealed the crucial and diverse role of the nutrient elements, i.e., cobalt (Co), potassium (K), and boron (B) in the overall growth of pulse crops under normal as well as stress conditions [21][22][23]. Cobalt is involved with vital physiological and biochemical functions in plants [24], especially the synthesis of leghaemoglobin protein required for rhizobial activity in legumes and subsequent nitrogen fixation manifesting momentous impact on enzyme systems [25].…”

Heat and soil moisture stress account for serious abiotic constraint in black gram (Vigna mungo (L.) Hepper) production during spring–summer under Gangetic plains of Eastern India. Concurrence of these two can bring about early completion of phenophases that hampers normal metabolism of legumes by disrupting their defense mechanism, leading to poor seed set. The field experiment was conducted with two different sowing dates as the main plot, soil application of cobalt (Co) as subplots and foliar sprays of potassium (K) and boron (B) either alone or in combination as sub–sub plot treatment in a split–split plot design during spring–summer seasons of 2020 and 2021 with black gram (variety: Pant U 31). The study was aimed at evaluating the impact of sowing time and nutrients application alleviating adversities of abiotic stress during reproductive development of black gram. The March first week sown crop took significantly higher days to complete its life cycle compared to March third week sown one (82.0 vs. 78.2 and 81.8 vs. 78.8). This in turn relatively allowed a broader window for leaf area expansion, flowering, and seed filling in the first crop compared to the second one leading to the attainment of superior yield in the normal sown crop during the consecutive years. Crop growth rate (CGR), net assimilation rate (NAR), pod number per plant, seed yield, and harvest index were significantly higher (p ≤ 0.05) with soil Co @ 4 kg ha−1 and foliar 1.25% K + 0.2% B applications through stress mitigation by stimulating chlorophyll biosynthesis, nitrate reductase activity, proline accumulation, and cell membrane stability, irrespective of the years. Fluctuations in per plant pod number explained about 96 and 94% variations in seed yield through linear regressions in respective years. Optimum sowing date along with soil Co application combined with foliar K+B sprays manifested immense potential to achieve higher black gram production. In addition, this nutrient schedule proved to be efficient enough to promote satisfactory growth and optimum seed yield of late sown blackgram through relief of stress during the spring–summer season.

Background: Indian agricultural sector requires a huge consumption of total available water for the sake of optimum crop production. The modern era of water scarcity necessitates the escalation of water use efficiency of crops to secure higher portion of economic harvests per drop use of water in agriculture. Against this background, it is requires to introduce lesser water consuming crops like pulses, oilseeds etc with innovative and cost-effective agronomic interventions for the purpose of contributing towards conservation of more water. Methods: A field experiment was conducted at District Seed Farm, ‘A-B’ Block of Bidhan Chandra Krishi Viswavidyalaya, West Bengal, during subsequent winter seasons of 2017-18 and 2018-19 to evaluate the effect of seed priming with molybdenum and foliar fertilization on moisture utilization of relay grass pea, variety Ratan (Bio L-212) without irrigation, using seed priming with Ammonium molybdate and foliar spray of 2% Urea and 0.5% NPK (19:19:19) in different combinations. Result: Maximum water use efficiency of 16.65 and 14.80 kg ha-1 mm-1 in the respective years were recorded with seed priming combined with twice foliar spray of 0.5% NPK (19:19:19) with the highest yield and moisture consumption. Total soil moisture content was found to be an exponential function of dry aerial biomass, but shared a polynomial correlation with leaf area index at different growth stages of grass pea. However, water use efficiency exhibited strong and polynomial correlation with seed yield and stover yield of grass pea in both the years. The combination of seed priming with Ammonium molybdate @ 0.5 g kg-1 seed along with a twice foliar spray of 0.5% NPK (19:19:19) will be a profitable technology for the relay grass pea growers in new alluvial zone of West Bengal.
