A pot experiment was conducted at Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur during kharif II season of 2011 to investigate the growth, dry matter production and yield of mungbean genotypes under nutrient stress soil. Ten mungbean genotypes viz., IPSA-12, GK-27, IPSA-3, IPSA-5, ACC12890053, GK-63, ACC12890055, BARI Mung-6, BUmug- 4 and Bina moog- 5 and six nitrogen fertilizer levels viz., 0, 20, 40, 60, 80 and 100 kg N ha-1 were included as experimental treatments. Results revealed that increasing nitrogen level in nutrient stress soil increased growth and dry matter production up to 60 kg N ha-1 irrespective of genotype and thereafter decreased. Among the mungbean genotype IPSA 12 showed maximum leaf area, dry matter production and seed yield (14.22 g plant-1) in nutrient stress soil. The lowest seed yield (7.33 g plant -1) was recorded in ACC12890053 under control condition.Bangladesh J. Agril. Res. 42(1): 77-85, March 2017

Matter Production

The effect of serial planting on dry matter production, leaf area, grain yield and yield components cf Lupinus angustifoiius (cvv. Uniwhite, Uniharvest and Unicrop) and L. albus (cv. Ultra) was investigated in field plots at Rutherglen in 1973 and 1974. Delayed planting reduced dry matter production of all cultivars, and leaf area for Ultra. Differences in dry matter partitioning were observed between the late flowering Uniharvest, and the early flowering Unicrop and Ultra. In Uniharvest, delayed plantings resulted in a greater proportion of total dry matter being produced during the flowering phase, whereas the reverse was true for Unicrop and Ultra. The later flowering cultivars showed marked grain yield and yield component reduction with later sowing. Yields were reduced by 160.6 kg/ha and 222.5 kg/ha for each week's delay in sowing Uniharvest and Uniwhite, respectively. This effect was offset in the early flowering cultivars by greater development of lateral branches. In addition, when Unicrop and Ultra were planted in April, pod and flower abortion on the main stem resulted from low temperatures at flowering time. Optimum sowing time was early April for Uniwhite and Uniharvest, and early May for Unicrop and Ultra. Excellent vegetative growth under ideal moisture conditions highlighted the poor harvest indices of lupins and the scope for genetic improvement in the genus.

Aerobic rice is a new way of cultivating rice that requires less water than lowland rice. A field experiment was conducted during the kharif season of 2015 to evaluate the effects of nutrient management with Biofertilizers on growth and yield attributes, yield, nutrient uptake and economics different rice cultivars. The experiment was laid out split plot design with four replications. Main plot treatments consisted of two cultivars viz., whereas, sub plot treatments comprised of nutrient management practices namely, N1-125% RDF, N2-125% RDF + Biofertilizers, N3 -100% RDF, N4 -100% RDF + Biofertilizers, N5-75% RDF, N6-75% RDF + Biofertilizers. The source of biofertiliser was a combination of Azospirillum, Phosphorus Solubilizing Bacteria and Potassium Solubilizer applied @ 5 kg/ha-1. Crop dry matter production (2582.3 g/m2), root dry matter production (910.1 g/m2), tillers/m2 (566), leaf area index (4.54), panicles/m2 (535), panicle length (23.81), panicle weight (4.56) and test weight (25.3) was higher in PA 6444 compared to DRR Dhan 44. Higher uptake of nutrients was also observed in PA 6444. Rice fertilized with 125% RDF + Biofertilizers (N2) produced higher crop (2901.6 g/m2) and root dry matter production (1028.1 g/m2), tillers/m2 (561) and leaf area index (5.19). This treatment also recorded higher yield attributes and grain yield (3.55 t/ha). With respect to nutrient uptake, application of 125% RDF + Biofertilizers (N2) recorded      higher N, P and K uptake by grain and straw and higher profitability (1.57) than other nutrient combinations.

Background: In the recent years, the yield plateau of the major cereals together with the climate change concerns, the potential of millets and pulses have been identified as pivotal for addressing the agrarian and nutritional challenges. The present study was conducted to assess the feasibility of intercropping green gram, black gram and cowpea in finger millet.Methods: A field experiment was conducted during summer 2019-2020 (February to May, 2020) to assess the variation in the growth and yield of pulses, viz., green gram, black gram and cowpea on intercropping with finger millet, along with and without AMF inoculation.Result: Pulses were observed to be significantly taller when intercropped with finger millet in the presence of AMF. Leaf area index (LAI), dry matter production, seed yield and haulm yield were higher for sole crops. Between the intercropping treatments, with and without AMF, LAI, dry matter production and seed yield were superior when pulses where intercropped in finger millet inoculated with AMF. Intercropping finger millet with cowpea recorded the highest finger millet equivalent yield (FMEY) followed by black gram and green gram. The treatment, T6 (finger millet with AMF + cowpea) registered the highest FMEY (3388 kg ha-1) followed by T5 (3234 kg ha-1). Intercropping finger millet (with AMF) with black gram (T4) and green gram (T2) recorded FMEY of 2708 kg ha-1 and 2497 kg ha-1 respectively.

A field experiment was conducted at the Research farm, Division of Agronomy, Sher-e-Kashmir University of Agricultural Sciences and Technology, India for two consecutive rainy (kharif) seasons of 2009 and 2010 to find out the impact of nitrogen, sulphur and farmyard manure (FYM) on growth and yield of sunflower (Helianthus annuus L.). Application of 120 kg N ha-1 significantly increased all the yield components viz., plant height, leaf area index, dry matter production, capitulum diameter, achenes capitulum-1 and 1000-seed weight. Pooled yield increased by 26% with 120 kg N but it was statistically at par with 80 kg N ha-1. With increased N dose, the oil content consistently decreased but the oil yield improved during both years. Sulphur application at the rate of 60 kg ha-1 significantly increased plant height, leaf area index and dry matter production after 25 days of sowing (DAS). All yield contributing characters viz., filled achenes capitulum-1, head diameter and 1000-seed weights were higher with 60 kg S ha-1 over 30 kg S ha-1. Seed and stalk yield with 60 kg S ha-1 were significantly higher than those of 30 kg S ha-1. Similarly, oil content and oil yield with 60kg Sha-1 was 2 and 10.5 % over 30 kg S ha-1. Application of FYM at the rate of 10 and 20 t ha-1 was at par with each other but recorded significant improvement in the plant height, leaf area index and dry matter production of sunflower after 25 days of sowing over no FYM. FYM @10 and 20 t ha-1 increased the oil yield by 11 and 5.4 %, respectively over no application. DOI: http://dx.doi.org/10.3329/sja.v11i1.18386 SAARC J. Agri., 11(1): 81-89 (2013)

Growth and yield of chickpea, Cicer arietinum cv. Tyson, were studied at 4 row spacings (180, 360, 530 and 710 mm) and 4 plant population densities (14, 28, 42 and 56 plants m-2) in factorial combination in a wet and a dry growing season on a vertisol at Dalby, south-eastern Queensland. In both years, row spacing had only a small effect on above-ground dry matter production and yield, and there were no significant interactions between row spacing and plant population density. Above-ground dry matter production increased significantly with increase in plant population density for about 120 days after sowing. Seed yield increased significantly from 104 to 126 g m-2 in the drier season (106 mm rain, May-October) with increase in plant population density from 14 to 56 plants m-2. In the wetter season (286 mm rain, May- October), the corresponding trend in yield was from 262 to 287 g m-2. The response was attributed chiefly to larger seed size in the wet year, and higher harvest index in the dry year. We conclude that a density of at least 40 plants m-2 is required to attain maximum seed yield in southeastern Queensland. Although row spacing had no significant effect on yield, our earlier research indicated potential benefits from narrow row spacing, particularly for mechanised crop production.

Sulphur is a component of plant amino acids, proteins, vitamins, and enzyme structures which influence the productivity of oil seed and total oil content. The experiment was conducted to find out the effect of sulphur on the seed yield and oil content of sesame in Bangladesh. The experiment comprised three varieties of sesame viz. Binatil-2, Binatil-3 and BARI Til-4 and six levels of sulphur (S) viz. 0, 10, 20, 30, 40 and 50 kg S ha–1. The experiment was laid out in a randomized complete block design with three replications. Dry matter production, crop characters, yield components, seed yield and oil content were significantly influenced by variety, level of sulphur and their interaction. The highest dry matter production plant–1 at 50 DAS (17.56 g), plant height (101.3 cm), number of branches plant–1 (3.66),  number of pods plant-1 (41.56), number of seeds pod-1 (58.83),  seed yield    (747.2 kg ha-1), stover yield (2243.0 kg ha–1) and oil content (40.03%) were obtained in BARI Til-4 while the corresponding lowest values of all parameters were recorded in Binatil-2. In case of sulphur application, the highest dry matter production plant–1 at 50 DAS (20.81 g), plant height (109.7 cm), number of branches plant–1 (3.87),  number of pods plant–1 (46.13),  number of seeds pod-1 (56.67),  seed yield (800.0 kg ha–1), stover yield (2787 kg ha–1 ) and oil content (43.97%) were obtained when crop was fertilized with 30 kg S ha–1 while the lowest seed yield (502.2 kg ha–1), stover yield (1550.0 kg ha–1) and oil content (32.80%) were obtained in control (0 kg S ha–1). BARI Til-4 fertilized with 30 kg S ha–1 produced the highest dry matter plant–1 at 50 DAS (24.80 g), number of pods plant–1 (51.13), seeds pod–1 (62.0) and seed yield (1011.0 kg ha–1). The highest oil content (43.97%) was also recorded in BARI Til-4 fertilized with 30 kg S ha–1, which was as good as that of BARI Til-4 fertilized with 40 kg S ha–1. Therefore, BARI Til-4 fertilized with 30 kg S ha–1 can be considered as a promising practice in respect of seed yield and oil content of sesame in Bangladesh. J. Bangladesh Agril.

The objective of this work was to study morphogenic characteristics, and dry matter production of roots and shoots of marandu palisadegrass (Brachiaria brizantha cv. Marandu) submitted to combinations of nitrogen and potassium, in a nutritive solution, employing silica as substrate. The experiment was carried out in a greenhouse during the summer. It was used a 5² fractionated factorial scheme with 13 combinations of nitrogen and potassium, which were distributed in a randomized block design, with four replications. The nitrogen × potassium interaction was significant for the number of tillers and leaves, for leaf area, for shoots and root section dry mass, for total length and surface and specific length and surface in the roots. Production of aerial part dry mass positively correlated with the number of tillers and leaves and grass leaf area. Nitrogen rates modulated the root system development, and the root specific length and surface decreased when high rates of nitrogen and potassium were supllied. Nitrogen and potassium influence Marandu palisadegrass morphogenic characteristics, which are determinant for grass dry matter production.
