The effects of periods of drought during different phases of reproductive growth of faba bean (Vicia faba L.) cv. Xichang Dabai were investigated in a pot experiment at Xichang Agricultural College, China. Parameters were total dry matter; seed yield; yield components; concentrations of nitrogen, phosphorus, and potassium; and total uptake in different organs. All drought treatments decreased total dry matter production and seed yield per plant. Plants subjected to drought from initiation of pod-set to full pod-set (stage D4) produced 32% less total dry matter and 45% less seed yield than the irrigated control. Mean seed weight was a relatively stable yield component. Statistical analysis indicated that only plants subjected to drought at stages D4 and D5 (drought from full pod-set to maturity) had a significantly (P < 0·05) lower mean seed weight than the control. The nutrient concentration was generally high in the younger or more active organs of faba bean, and comparing the nutrients, the N concentration in leaves, stems, flowers, pods, and grain was greatest, followed by K concentration, and P concentration was least. All soil drought treatments decreased the nutrient concentration in various organs after 17–19 days of drought. However, the decreases at maturity were less clear, except the nutrient concentrations in stems and leaves. Water deficit significantly decreased total grain nutrients per plant, the decreases being 34–45% for N uptake, 34–47% for P uptake, and 33–46% for K uptake. Simple linear correlations with the P and K concentration in leaves at maturity and number of pods and seeds per plant gave a correlation coefficient (r) of 0·804–0·874.

SUMMARYThe effects of periods of drought occurring during different phases of reproductive growth of faba bean (Vicia faba L.) cv. Xichang Dabai on dry matter production, seed yield, photosynthetic rate and stomatal size were investigated in pot experiments in 1987/88 and 1988/89 at Xichang Agricultural College, China. Six treatments were imposed: no drought (control), and drought from floral initiation to first flowering (D1), from first flowering to full bloom (D2), from full bloom to initiation of podset (D3), from initiation of pod-set to full pod-set (D4), and from full pod-set to maturity (D5).Photosynthetic rate, chlorophyll content, leaf area, stomatal pore breadth, biomass and seed yield were decreased by all drought treatments, but stomatal frequency and respiratory rate were increased. The light saturation point for photosynthesis was decreased from 950 µmol/m2/s (PAR) to 570 µmol/m2/s (PAR) in leaves from drought-stressed plants, which also showed maximum stomatal opening between 08.00 and 11.00 h followed by progressive stomatal closure.The response of faba bean to drought varied during the different reproductive growth stages. Plants subjected to drought at stage D1 were less affected than those at other stages, while plants at stage D4 were most sensitive to drought, which reduced seed yield by c. 45% in 1987/88 and by c. 43% in 1988/89 relative to the control plants, suggesting that stage D4 is the stage of reproductive development most sensitive to soil drought in the faba bean.

Progenies from a five-genotype diallel cross in Russian wild ryegrass, Elymus junceus Fisch., were studied to assess the pattern of genetic control for F1 seed weight and a number of seedling and adult plant characters. Variation in F1 seed weight was largely determined by the maternal parent, but some control by the pollen parent was apparent. Of the seedling characters, days to emerge, rate of leaf appearance, rate of tiller appearance, and seedling dry matter yield, only days to emerge showed additive variance which is amenable to direct selection. The other three characters could be most easily exploited by a recurrent selection program. The adult plant characters, date of inflorescence appearance, P content of the forage, and organic matter digestibility indicated strong additive control which is amenable to direct selection. Dry matter yield and seed yield also showed strong additive control which was accompanied by specific combining ability and weak maternal effects suggesting good progress should be possible by direct selection methods but crossing the selections in a diallel fashion prior to formation of synthetics might be desirable. The seedling characters, rate of leaf and tiller appearance and seedling dry matter yield were interrelated and associated with adult plant yield, thus offering the possibility of screening seedlings for these characters in a recurrent selection program for improved forage or seed yield.

A near-isogenic faba bean (Vicia faba L.) line, segregating in a 1:1 ratio of male-fertile to male-sterile plants, was used to study the importance of insect pollinators on ovule fertilization and yield components of the first five flowering nodes. The fertilization of ovules from open-pollinated plants at the higher insect pollinator site of Dijon, France was 83%, as compared with 50% at the lower insect pollinator activity site of Saskatoon, Canada. No significant differences in total fertilized ovules were found between male-fertile and male-sterile plants at Dijon, but male-fertile plants at Saskatoon had significantly more fertilized ovules than male-sterile plants. Seed production on the first five flowering nodes was significantly greater at Saskatoon. Thus, while insect pollinators are important in determining the potential yield of a faba bean plant, other factors, such as environment, determine the ultimate yield.Key words: Vicia faba, ovule fertilization, seed yield, faba bean, male sterility

The valorization of municipal solid waste (MSW) can serve as an organic amendment in agriculture while reducing solid waste accumulation in the environment. This research aimed to evaluate the valorization of a bio-stabilized MSW amendment for the production of faba bean (Vicia faba L.) crop. For this purpose, biomass production and growth, as well as, seed yield and seed components, seed nutrient accumulation, plant pigments, soil properties, and microorganisms were evaluated in comparison with faba bean mineral fertilization in a greenhouse experiment. The results demonstrated that the bio-stabilized MSW amendment achieved similar biomass production, plant growth, seed yield, nitrogen and protein content, and pigment content as the mineral fertilization treatment. On the other hand, the organic fertilization did not exhibit significant effects on the yield components number of pods per plant, and number of seeds per pod, and nutrient accumulation in seeds with respect to mineral and control treatments in both soils. Sandy and clay soil properties were improved in the organic treatments in comparison with the control soils by increasing soil organic carbon, nitrogen, and other soil nutrients, and providing a suitable pH for faba bean growth. Additionally, biological activity was favored by applying this source of organic fertilizer, enriching the nematode community. Reusing bio-stabilized MSW for agronomical purposes can add value to this waste product, serving as an effective alternative to mineral fertilizers in faba bean cultivation.

Effect of detopping and mepiquat chloride on morphological, physiological and yield attributes of soybean cultivar ‘SL 544’ was studied. A two year investigation was conducted at Punjab Agricultural University, Ludhiana, during kharif seasons of 2014 and 2015. The experiment was laid-out in randomized complete block design (RCBD) with eight treatments viz. control, detopping (removal of 4-5 cm apical portion of main stem) at 50-55 days after sowing (DAS), mepiquat chloride @ 200 ppm (50-55 DAS), mepiquat chloride @ 200 ppm (50-55 + 65-70 DAS), mepiquat chloride 250 ppm (50-55 DAS), mepiquat chloride @ 250 ppm (50-55 + 65-70 DAS), mepiquat chloride @ 300 ppm (50-55 DAS) and mepiquat chloride @ 300 ppm (50-55 + 65-70 DAS) with four replications. Detopping had a non-significant effect on leaf area index, SPAD value, PAR interception, abscission of reproductive parts, seeds per pod, 100-seed weight, pod length and stover yield of soybean. It significantly decreased plant height, increased total dry matter accumulation/plant, number of flowers and pods/plant, pod setting percentage and seed yield over control during 2014 and 2015. At crop harvest, detopping developed optimized source-sink relationship by means of distribution of total dry matter between stem, foliage and pods by 20.4, 14.9 and 64.6 % during 2014 while 22.6, 20.1 and 57.4 % during 2015, respectively. Mepiquat chloride posed a non-significant effect on plant height, PAR interception, number of flowers/plant, number of seeds/pod, pod length and stover yield of soybean but it significantly decreased leaf area index, abscission of reproductive parts while increased the dry matter accumulation/plant, number of pods/plant, 100-seed weight and seed yield relative to control. At harvest, two foliar applications of mepiquat chloride @ 250 ppm resulted in optimized source-sink relationship by the distribution of total dry matter among stem, foliage and pods by 20.6, 10.9 and 68.5 % during 2014 while 19.5, 7.6 and 72.9 % during 2015, respectively. Occurrence of more rainfall during 2015 as compared to 2014 caused mepiquat chloride to hike seed yield as compared to detopping which is clearly witnessed by increase in pod dry weight per plant during 2015 than 2014. Conclusively, both detopping and mepiquat chloride resulted in enhancement in source-sink relationship and seed yield of soybean.

A field experiment was carried out at University of Dhaka from March to July, 2011 to study the effect of time of sowing on the growth and yield of BARI mung-5. The treatments consisted of three dates of sowing viz. March 15, April 15 and May 15. The crop responded significantly to sowing time and 15 April sowing seeds produced plants having maximum plant height (68.4 cm), leaves/plant (29.33), total dry matter/plant (17.99), branches/plant (8.17), pods/plant (11.33), pod length (8.78 cm), seeds/pod (11.17), 1000 seed weight (46.52 g), seed yield/plant (5.33 g), yield/ha (1.77 t) and harvest index (29.58 %) at harvest. The seed yield decreased by 36.8 and 49.9% when seed sown early (15 March) or late (15 May) due to production of lower yield components.   DOI: http://dx.doi.org/10.3329/jbas.v36i2.12966   Journal of Bangladesh Academy of Sciences, Vol. 36, No. 2, 227-231, 2012

Plot Design

Growth, development and yield of three-grain legumes (mung bean [F1], soybean [F2] and grass pea [F3]) following rice crop to enhance grain production was studied in a paddy field in the northern Timor-Leste. A split plot design was used with three water treatments (well-watered [W0], water withheld at flowering [W1] and after germination [W2]). Interaction between water treatments and species on dry matter production (p < 0.001) and seed yield (p = 0.005) was observed. In control, the highest seed yield was F1 (1.2 t/ha) followed by F2 (1.1 t/ha) and F3 (0.4 t/ha) respectively. There was a steady reduction in seed yield in F1 from W0 to W2, but almost fifty percent reduction in F2 under W1 and W2 compared to W0. F3 had little difference between water treatments. The W1 and W2 reduced number of filled pods per plant in all species compared to control (W0). Between the species, F3 had the highest filled pods per plant followed by F2 and F3. The W1 and W2 reduced seeds per pod of F1; however, it did not effect F2 and F3. There were interactions between water treatment and species on 100 seeds weight. The heaviest seeds were in F2 in the control plants, but in the F2 drought treatments (W1 and W2) seed weight were less than F3. The lowest seed weight was in F1, but there was no impact of the terminal droughts on its seed weight.

Intercropping is the cultivation of two or more crop species on the same area of land, and can improve yield, forage quality, and soil health. Despite the fact that intercropping is an old practice, it received significant attention the last years because of the environmental impact that it has. However, the effect of the various spatial arrangements of the different species that are used in an intercropping system was not determined. The objective of the present study was to study the yield, growth and nitrogen (N) uptake rate, N nutrition index (NNI) of barley, interspecific competition, quality and financial outcome of intercrops of faba bean (Vicia faba L. var. equina) and barley (Hordeum vulgare L.) with various spatial arrangements (1:1, 2:2, 2:1 alternate rows, and mixed in the same row). The land equivalent ratio (LER), relative crowding coefficient (K), actual yield loss (AYL) and system productivity index (SPI) values were greater for the FB:B intercrop of 2:1, indicating the advantage of intercropping in terms of dry matter and N yield. Sole cropping of barley showed a reduction in NNI by 7 %, whereas NNI for barley increased by an average of 14% in intercropping treatments. Based on biomass production and the competition indices for dry matter and N yield, and NNI the FB:B intercrop of 2:1 was more advantageous than faba bean and barley monocrops, as well as the other intercropping treatments that were tested.   ********* In press - Online First.
