The experiment was carried out at the Bangladesh Agricultural Research Institute, Gazipur during summer season of 2012 to identify suitable legume crops for growing with maize in a maize + legume intercropping system for better weed suppression, system productivity and economic benefits in kharif season. There were 17 treatments, viz.T1= Sole maize (no weeding), T2= Maize + Mungbean (no weeding), T3= Maize + Mungbean (weeding at 20 DAE), T4= Maize + Mungbean (weeding at 40 DAE), T5= Maize + Mungbean (weeding at 20 and 40 DAE), T6= Maize + Soybean (no weeding), T7= Maize + Soybean (weeding at 20 DAE), T8= Maize + Soybean (weeding at 40 DAE), T9= Maize + Soybean (weeding at 20 and 40 DAE), T10= Maize + Blackgram (no weeding), T11= Maize + Blackgram (weeding at 20 DAE), T12= Maize + Blackgram (weeding at 40 DAE), T13= Maize + Blackgram (weeding at 20 and 40 DAE) T14 =Sole maize (weed free), T15= Sole Mungbean (weed free), T16= Sole Soybean (weed free) and  T17= Sole Blackgram (weed free) were studied. Intercropping systems significantly reduced the weed population and weed dry biomass in comparison to sole cropping of maize under unweeded situation. Among the three different intercropping systems, maize + mungbean with two hand weedings produced the lowest weed dry weight (184.30 g at 20 DAE and 14.07 g at 40 DAE)  and the highest weed control efficiency (87% at 40 DAE) followed by maize + soybean and maize + blackgram intercropping systems. The highest grain yield was obtained from weed free sole maize (8.05 t ha-1) than unweeded sole maize (6.48 t ha-1) treatment. Among all intercropping, maize + mungbean along with two hand weedings gave the highest yield (maize: 7.18 t ha-1; 572.6 kg ha-1 mungbean), resource complementarity and profitability (MEY = 10.62 t ha-1, LER = 1.81 and BCR = 2.47). From the study it was concluded that maize + mungbean with two hand weedings at 20 and 40 DAE would be the best in reducing weed growth, producing maximum yield and getting net return in intercropping systems during kharif season.

The experiment was conducted at the research field of Agronomy Division, Bangladesh Agricultural Research Institute (BARI), Joydebpur, Gazipur during rabi seasons of 2014-15 and 2015-16 to find out the suitable planting arrangement of squash (var. Bulam House) with maize (var. BARI Hybrid maize-9) as intercropping for higher productivity and economic return. Seven treatment combinations viz. maize normal plating (75 cm Í 25 cm), maize normal plating (75 cm Í 25 cm) (100%) + 1 row squash (Plant to Plant 80 cm) (116%), maize paired row (37.5 cm Í 150 cm Í 37.5 cm) (100%) + 1 row squash (Plant to Plant 80 cm) (50%), maize paired row (100%) + 1 row squash (Plant to Plant 100 cm) (40%), maize paired row (100%) + 2 rows squash (Plant to Plant 80 cm) (100%), maize paired row (100%) + 2 rows squash (80%) (Plant to Plant 100 cm) and sole Squash (100 cm × 80 cm) were tested. Results showed that the highest grain yield of maize (9.47 t ha-1 in 2014-15 and 9.24 t ha-1 in 2015-16) and squash yield (28.19 t ha-1 in 2014-15 and 25.02 t ha-1 in 2015-16) were recorded in sole crop, respectively. Maximum mean maize equivalent yield (19.39 t ha-1) was recorded in maize paired row (100%) + 2 row squash (Plant to Plant 80 cm) (100%) combination in both the year. The highest gross return (Tk. 2,93,850 ha-1), gross margin (Tk. 1,92,450 ha-1) and BCR (2.95) were also obtained from the same combinations. Two years’ results revealed that maize paired row + 2 rows squash (Plant to Plant 80 cm) combination could be suitable for higher productivity and economic return. Bangladesh Agron.

High Yielding Varieties

This paper describes two experiments analysing the recovery from defoliation of subterranean clover varieties grown in swards in large seed boxes at the Waite Agricultural Research Institute, Adelaide. The first experiment examined the way in which the six common commercial varieties recovered from a single severe defoliation, and showed that under these conditions they can be placed in three groups: Yarloop and Clare are tall, high-yielding varieties with few, large leaves, recovering slowly from defoliation; Tallarook and Dwalganup are prostrate varieties, lower-yielding, with many small leaves, recovering rapidly after defoliation; Bacchus Marsh and Mount Barker are intermediate in all respects. In the second experiment mixed swards of equal numbers of Yarloop and Tallarook plants were grown under three treatments: A, no defoliation; B, defoliated twice at a height which removed the higher Yarloop canopy but left the lower Tallarook plants untouched; C, defoliated twice at a height which removed the canopies of both varieties. Measurement of dry weight on four occasions after each defoliation showed that in the undefoliated treatment, all Tallarook plants died by the end of the experiment. In the defoliated treatments, the removal of the Yarloop canopy resulted in only a temporary improvement in the illuniination in which the Tallarook plants grew, and their dry weight and plant numbers progressively declined. Dry weight changes in the Tallarook component were shown to be dependent on the light energy available to it, which was in turn determined by the light-absorbing capacity of the superior Yarloop canopy. In mixed swards, the ability of Yarloop to re-establish quickly a leaf canopy above that of Tallarook appeared to explain its success when defoliated.

Hybrid Maize

Need  for corn is increasing, both for food, animal feed, and industrial raw materials. This is an opportunity as well as a challenge for the government in increasing corn production towards sustainable self-sufficiency. Superior varieties are one of the components that can significantly increase yield. Hybrid varieties have a higher yield potential than composites so that the use of hybrid corn seeds can increase the yield of corn per crop area. The Agricultural Research and Development Agency (Balitbangtan) has produced hybrid maize varieties with high yield potential, which are no less competitive with other private hybrid maize, but they are not well disseminated. In order to obtain added value for farmers and the development of Balitbangtan corn seeds, NASA 29's hybrid corn seed propagation was carried out at the farmer level. The study was carried out in Salukayu Village, Papalang District, Mamuju Regency in 2018 covering an area of ​​1 ha. The results showed that corn seeds were 1.5 tons / ha. The Nasa 29 hybrid maize seed propagation farm is economically feasible and profitable, as indicated by the R / C value of 2.35, TIP 637 kg / ha, TIH Rp. 10,623, - / kg and IK Rp. 88,985, / day. The study of the propagation of the NASA 29 hybrid maize seed was financially feasible and the economic benefits were high and efficient.

The experiment was carried out at Agronomy Research field of Bangladesh Agricultural Research Institute (BARI), Joydebpur, Gazipur and Regional Agricultural Research Station, Hathazari, Chittagong to find out optimum sowing date of sunflower during rabi season 2012-13. The sunflower var. BARI Surjomukhi-2 was used. Five sowing dates; 10 November, 20 November, 30 November, 10 December and 20 December were tested. It was revealed that yield and yield attributes of sunflower were significantly influenced by sowing dates. The maximum plant height (172.13 cm), head diameter (18.33), weight of seed / per head (66 g), 1000- seed weight (68 g) and yield (2.5 t ha?1) were obtained from 20 November sowing. The lowest yield (1.83 t ha?1) was obtained from 20 December sowing. The 20 November sowing received the higher duration for maturity (127 days), first flowering (57 days) and seed formation (20 days) while 20 December sowing showed shorter duration for maturity, first flowering and seed formation of 119, 54 and 14 days respectively. It was concluded that the 20 November sowing would be the optimum time of sowing for achieving maximum yield of sunflower.Bangladesh Agron. J. 2015, 18(1): 1-5

Mature seeds of three chickpea varieties like BARI Chhola-5, 6 and 8 were collected from three different branches like primary, secondary and tertiary, and were evaluated for quality in the Seed Technology Laboratory, Bangladesh Agricultural Research Institute, Gazipur, Bangladesh during August to September of 2004 and 2005. All the seeds were stored in earthen pot for five months before conducting the laboratory study. Significant variation was observed in all three varieties of chickpea for all the parameters studied except seed vigour. The highest moisture percentage (10.17 in 2004 and 10.18 in 2005), dry weight (0.50 g in 2004 and 0.51 g in 2005) and seed vigour (39.7 in 2004 and 41.6 in 2005) was observed in BARI Chhola-8 and the lowest in BARI Chhola-5. Germination percentage was significantly higher in BARI Chhola-5 (87.6 in 2004 and 88.9 in 2005). Seeds of different branches did not vary significantly for most of the parameters. However, seeds of primary or secondary branches had higher moisture and germination percentage, dry weight of seedling and seed vigour. Interaction effects of varieties and seeds of different branch had no definite trend though non-significant effect was observed in most of the parameters.
