An experiment was conducted at the Agronomy Field Laboratory of Bangladesh Agricultural University, Mymensingh to assess the effect of weeding on growth, yield and yield contributing characters of mungbean (Vigna radiata L.) cv. BINA mung- 4 during October 2011 to February 2012. The experiment was laid out in a randomized complete block design with four replications. The trial comprised seven treatments namely, T1 = no weeding, T2 = one-stage weeding (Emergence-Flowering), T3 = one-stage weeding (Flowering-Pod setting), T4 = one-stage weeding (Pod setting- Maturity), T5 = two-stage weeding (Emergence-Flowering and Flowering-Pod setting), T6 = two-stage weeding (Flowering-Pod setting and Pod setting-Maturity) and T7 = three-stage weeding (Emergence-Flowering and Flowering-Pod setting and Pod setting-Maturity). The growth parameters such as relative growth rate (0.075 g g-1 day- 1) and net assimilation rate (0.075 g m-2day-1) showed the best performance with T2 at one-stage weeding condition (Emergence-Flowering). Three-stage weeding ensured the highest plant height (58.62 cm) as well as the highest number of branches (4.45) and leaves (10.34) plant-1. Dry weight plant-1 (12.38g) was highest from three stage weeding and the lowest from no weeding treatment. The highest number of pods (22.03) plant-1, the longest pod (5.95 cm), the highest number of seeds (17.07) pod-1 and the highest seed yield (1.38 t ha-1) were obtained from three-stage weeding (Emergence-Flowering and Flowering-Pod setting and Pod setting-Maturity) in mungbean. On the other hand, the lowest seed yield was obtained under no weeding condition. The highest seed yield resulted in higher biological yield (4.70 t ha-1) and the highest harvest index (37.15%) in three-stage weeding and the lowest from no weeding. Number of pods plant-1, length of pod, number of seeds pod-1 and 1000-seed weight showed highly significant positive correlations with seed yield. These parameters strongly influenced the growth, yield and yield contributing characters of mungbean (Vigna radiata L.) DOI: http://dx.doi.org/10.3329/jbau.v11i1.18209 J. Bangladesh Agril.

Aims: To assess limitation on growth and yield of P. vulgaris due to Telfairia mosaic virus (TeMV). Study Design: The study was conducted in a randomized block design. Place and Duration: Department of Botany, University of Calabar, Calabar, Nigeria between April and August, 2016. Methodology: Seeds of P. vulgaris were obtained, sorted, planted in polyethylene bags, and on germination, inoculated with TeMV, growth and yield limitation assessed at 2, 4, 6, 8 and 12 weeks after inoculation. Results: Results showed that the virus decreased growth of P. vulgaris resulting in yield loses. Growth parameters were severely limited by TeMV with percentage reduction in Leaf area, shoot height, number of primary shoot, petiole length and number of leaves produced of 44.5%, 52.8%, 44.0%, 44.9% and 51.45 respectively at 10 weeks after inoculation (WAI). Leaf fresh weight (38.4%) and dry weight (32.3%) were significantly (P=0.05) reduced. Relative growth rate, net assimilation rate and leaf area ratio were negatively impacted by the virus with reductions of 26.5%, 36.7% at 4 WAI and 33.5% at 12 WAI respectively. Limitation on yield due to TeMV was significant (P=0.05) with reduction in pod length of 36.9%, number of pods per plant of 36.5%, number of seeds per pod of 26.5%, number of seeds per plant of 53.3% and weight of 100 seeds of 18.5%. Limitation induced on fresh and dry weight of shoot and root, pod width, seed length and seed width was not significant. Conclusion: The study confirmed the threat of TeMV necessitating control of the virus on this important legume.

Roselle (Hibiscus sabdariffa L.) is an important crop grown in tropical and subtropical climates with huge nutritional, economic and industrial benefits. The plant undergoes explosive shattering to disperse seeds after physiological maturity leading to high loss of seeds at the time of harvesting. A field experiment was carried out to determine the effect of different harvesting stages on the growth, yield and shattering dynamics of seeds of twelve Roselle accessions in the Department of Horticulture, Kwame Nkrumah University of Science and Technology, Kumasi from March to November, 2019. A 3x12 factorial design in Randomized Complete Block Design (RCBD) was used for the study, where factor one was harvesting stages at three levels (physiological maturity, one week after physiological maturity and two weeks after physiological maturity) and factor two was accessions at twelve levels. The study revealed that accession HS08 performed best in terms of growth (plant height, the number of leaves, number of branches and stem girth) and reproductive parameters (number of days to flowering) and accessions HS27 and HS08 produced the highest yield (number of pods, number of seeds per pod, and total seed yield). Harvesting of seeds at the physiological maturity stage happened to be the ideal time because seeds were harvested safely without any losses (0%) due to shattering as compared to the other harvesting stages. The study also established a very strong, positive and significant relationship between seed yield and number of leaves (r=0.7093) and the number of branches (r=0.9241). However, there was a strong but negative and significant relationship between seed yield and percentage seed shattering loss (r=-0.9633). There was a very strong, positive and significant relationship between number of leaves and stem girth (r=0.7769). The number of seeds per plant correlated positively with the number of pods (r=0.7358). A regression model which was given by the equation; Y (Seed yield)=670.96-0.3152 (Shattering loss), R2=0.9279, p<0.0000, indicated that shattering loss significantly affected seed yield to an extent that it contributed 93% of the variation in the seed yield.

Row spacing and seed rate are management practices that affect flax seed yield. Hence to find out the optimum quantity of seed rate and spacing for higher production in irrigated linseed, the present experiment was conducted under AICRP on Linseed, College of Agriculture, Nagpur during the Rabi Season of 2019-20. The Experiment was laid out in Factorial Randomized Block Design with three replications in which Factor A consist of two spacing i.e. T1 - 30 cm and T2 - 45 cm and Factor B includes four seed rate S1- 10 kg/ha, S2- 15 kg/ha, S3- 20 kg/ha, S4- 25 kg/ha. Results showed significant effects of seed rates and spacing on all growth and yield attributes, which reflecting the importance of seeding rate and spacing for linseed. Maximum plant height was recorded after using the seed rate at 25 kg/ha (S4) and with 30cm spacing (T1) which was at par with seed rate 20 kg/ha (S3). The other growth parameters like number of branches, number of capsules per plant and test weight was found higher in the treatment having the seed rate of 10 kg/ha (S1) and in the spacing of 45cm (T2). Seed yield of linseed was recorded highest by using the seed rate at 15 kg/ha, which was at par with at the seed rate of 20 kg/ha and in the closer spacing of 30cm between rows i.e. 9.15% more as compare to row spacing of 45cm. Gross monetary returns, net monetary returns and B:C ratio was also recorded maximum in the seed rate of 15 kg/ha and with 30cm row spacing. It is concluded that advancement in seed rate by lowering down up to 15 kg/ha increases the productivity and profitability of linseed.

Broccoli is a popular vegetable throughout the world and contains important nutritional features. This study was conducted to evaluate the effect the fertilization with different phosphorus sources (i.e., soil application of rock phosphate (RP) at 428 kg ha−1, calcium superphosphate (CSP) at 670 kg ha−1, phosphoric acid (PA) at 126 L ha−1 and monoammonium phosphate (MAP) at 334 kg ha−1) combined with biofertilizers (i.e., inoculation with phosphorin or mycorrhiza) on plant growth aspects, antioxidants enzyme activity, chemical constituents, yield and quality of broccoli leaves and heads (Brassica oleracea var. italica Plenck). The experiment was performed according to the randomized complete block design with three replications (n = 3), for two growing seasons (2018–2019) at the experimental farm of Benha University, Egypt. The obtained results showed that the highest values of plant height, leaf area, fresh and dry weight of leaves/plant, head weight and diameter, and the highest yield of heads ha-1 were recorded in plants that received MAP fertilizer and were inoculated with mycorrhiza. On the other hand, the highest value of head length, total carbohydrate and total soluble solids (TSS) content were observed in plants fertilized with PA and inoculated with mycorrhiza. The highest leaf nitrogen % and head ascorbic acid content, as well as the lowest head total phenol content were recorded in plants supplemented with MAP fertilizer and inoculated with mycorrhiza. Moreover, broccoli plants fertilized with PA and inoculated with mycorrhiza showed promising results in terms of phosphorus, potassium and total carbohydrate content, antioxidant activity and dehydrogenase activity. In conclusion, phosphorus may affect plant growth, yield and chemical parameters in broccoli plants depending on the fertilizer source, while inoculation with mycorrhiza may also have a beneficial impact on these parameters.

The study compares the growth, yield, and proximate composition of Amaranthus hybridus, Amaranthus cruentus, and Amaranthus deflexus, grown with poultry manure and NPK in relation to the unfertilized soil of Ilorin, Nigeria. Viable seeds of the Amaranths raised in nursery for two weeks were transplanted (one plant per pot) into unfertilized soil (control) and soils fertilized with either NPK or poultry manure (PM) at 30 Kg ha−1 rate arranged in randomized complete block design with four replicates. Data were collected on plant height, stem girth, number of leaves, leaf area, and number of branches from 1 week after transplanting (1 WAT). Fresh weight, dry weight, and proximate composition were determined at 6 WAT. Except for the length, breadth, and number of leaves, the order of growth parameters and yield in the three Amaranthus species was NPK > PM > control. NPK grown Amaranthus species had the highest protein while PM-grown vegetables had the highest ash content. Crude fibre in A. cruentus grown with PM was significantly higher than NPK and the control. The NPK treatment of A. hybridus and A. deflexus had the highest crude fibre content. NPK and PM favoured growth and yield of the Amaranthus species but influenced proximate composition differently.

An experiment was carried out to study the effect of time of tiller separation on grain growth and yield of transplant aman rice. The experiment consisted of 3 times of tiller separation viz. tiller separation at 25 (T1), 35 (T2) and 45 (T3) days after transplanting (DAT); and 5 levels of number of tillers kept hill-1 viz. intact hills (K0), 1 tiller kept hill-1 (K1), 2 tillers kept hill-1 (K2), 3 tillers kept hill-1 (K3) and 4 tillers kept hill-1 (K4). The experiment was conducted in randomized complete block design with three replications. The unit plot size was 4 m 2.5 m. With a few exceptions, the highest grain growth parameters like number of panicles hill-1, dry weight panicle-1, number of grains panicle-1, dry weight grain-1 and grain growth rate were observed when tillers were separated at 25 DAT but the lowest values were found at 45 DAT. The grain growth rate decreased with the advance of time. The highest grain yield (5.25 t ha-1) was obtained from tillers separated at 25 days after transplanting (DAT) but the lowest values (4.13 t ha-1) were recorded when tillers were separated at 45 DAT. The maximum grain yield (5.88 t ha-1) was found in intact hills, while the lowest values (2.64 t ha-1) were obtained when 1 tiller kept hill-1.
