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.

Eight maize varieties viz. four composites (Mohor, Barnali, Khoibhutta, and BARI Maize-6) and four hybrids (BARI Hybrid Maize-1, BARI Hybrid Maize- 3, BARI Hybrid Maize Top 1 & Pacific 984), were tested for their response to zinc fertilization (0 and 3 kg Zn/ha) at the Regional Agricultural Research Station (RARS), Jessore (AEZ-11, High Ganges River Floodplain) during 2002- 2005. The varieties were not equally responsive to Zn addition. Except BARI Hybrid Maize-3, all other hybrids showed higher response to Zn compared to composite varieties. Among the hybrids, the Pacific 984 had the highest response followed by BARI Hybrid Maize-1 and BARI Hybrid Maize Top 1, the later two showed identical response. Comparing the composite varieties, their response can be ranked as Barnali ≈ Mohor > Khoibhutta > BARI Maize-6. The result suggests that BARI Hybrid Maize-3 and BARI Maize-6 were the most Zn inresponsive (Zn efficient) varieties. Further it appeared that Pacific 984 gave the highest seed yield, 10.46 t/ha due to Zn application. So, the farmers can grow this variety with an application of Zn @ 3 kg/ha in the deficient soil. The results also indicate that the farmers can cultivate BARI Hybrid Maize-3 in the moderately zinc deficient soils with a minimum dose (1 to 2 kg/ha) of Zn fertilization.

Abstract. The adoption of Conservation agriculture (CA) contributes to sustainable production and its advantages include lower inputs and stable yields. This study was conducted in the research field of Regional Agricultural Research Station, Bhagetada, Dipayal, Doti during 2014 and 2015 to identify the effect of CA on grain yield and income of maize in Maize based cropping system. Both conservation and conventional agricultural (ConvA) practices were evaluated on two maize based cropping systems namely maize-wheat-mungbean (M-W-MB) and maize-lentil-mungbean (M-L-MB). For this purpose two maize varieties namely Raj Kumar and Arun-2 were used. The average productivity of maize under M-L-MB cropping system was 1.6% higher (5.75 t/ha) than M-W-MB cropping system (5.66 t/ha). The average grain yield of maize under CA was 16.7% higher (6.15 t/ha) than ConvA (5.27 t/ha). Rajkumar produced 43% higher average grain yield (6.73 t/ha) than Arun-2 variety (4.69 t/ha). The average net benefit was slightly higher (US$ 597.33/ha) under M-L-MB cropping system than M-W-MB cropping system (US$ 573.89/ha). Similarly, the average net benefit from CA was 102% higher (US$ 783.67/ha) than ConvA (US$ 386.79/ha). Rajkumar variety gave 127% higher average net benefit (US$ 813.49/ha) than Arun-2 (US$ 357.81/ha). The average benefit - cost (B:C) ratio of M-L-MB cropping system was slightly higher (1.72) than the average B:C ratio of M-W-MB cropping system (1.70). The average B:C ratio of CA was 42% higher (2.01) than ConvA (1.41). The average B:C ratio of Rajkumar variety was found 33% higher (1.95) than Arun-2 (1.46). The higher grain yield, net profit and B:C ratio were found in CA practices under M-L-MB cropping system and Rajkumar variety. This study suggests that hybrid maize planting and the adoption of M-L-MB cropping system should be used to increase grain yield and economic performance under CA practices.

A model was used to determine the economic benefits of using fungicides to control foliar diseases of seed corn. The components of the model were (i) increased net return to the seed company from fungicide usage, (ii) increased income, based on a wholesale price of $30 per unit of 80,000 seeds and a premium of $2 per unit of medium-sized seed, and (iii) increased expenses, calculated as the sum of fungicide and fungicide application costs, cost of processing increased seed, and increased payment to the grower by the seed company. Increased payment to the grower was calculated as the product of increased seed yield (before separation into fractions), May futures price for no. 2 commercial corn on 1 March, and an average inbred production factor. Increased net return was calculated by subtracting increased expenses from increased income. Yield data were obtained from fungicide trial experiments in commercial hybrid corn seed production fields in Iowa from 1990 to 1993. Of 169 fungicide treatments applied, 64 and 79% were profitable to the seed company and to the grower, respectively. The results from this study indicate that fungicide usage in hybrid corn seed production can be economically beneficial.

Drought stress causes stomatal behavior change in most plants. Water deficit condition caused by drought is one of the most significant abiotic factors reducing plant growth, development, reproductive efficiency, and photosynthesis, resulting in yield loss. Maize (Zea mays L.) holds a superior position among all the cereals due to its versatile use in the food, feed, and alcohol industries. A common demonstrative feature of a complex network of signaling pathways led by predominantly abscisic acid under drought conditions is stomatal aperture reduction or stomatal closure, which allows the plant to reduce water loss through the stomatal pore and to sustain a long time on water deficit condition. This study analyses the stomatal density, stomatal closure percentages, and guard cell aperture reduction using a microscopy-based rapid & simple method to compare guard cell response & morphological variations of three hybrid maize varieties viz. BHM (BARI hybrid maize)-7, BHM-9, and BHM-13 developed by Bangladesh Agricultural Research Institute (BARI). A drought treatment was applied to all varieties at two different vegetative stages, vegetative stage 3 (V3) and V5, until they reach V4 and V6, respectively. After drought exposure at the V4 stage, the percentage of closed stomata of BHM-7, BHM-9, and BHM-13 was 21%, 23%, and 33%, respectively. The reduction in the guard cell aperture ratio of BHM-7, BHM-9, and BHM-13 was 14.83%, 10.92%, and 33.85%, respectively. At the V6 stage, for the second set of plants, the closed stomata of BHM-7, BHM-9, and BHM-13 were 18%, 21%, and 34%, respectively. The rate of reduction in guard cell aperture ratio of BHM-7, BHM-9, and BHM-13 was 5.52%, 2.48%, and 38.75%, respectively. Therefore, BHM-13 showed maximum drought adaptation capacity compared to BHM-7 and BHM-9 due to the highest percentage of closed stomata and the highest percentage of reduction in aperture ratio.

A study was conducted to investigate genetic variability in physiological seed quality using viability and vigour tests which were conducted at the seed testing laboratory of Institute of Agricultural Research and Training (IAR&T), Moor Plantation, Ibadan.  The investigational materials consisted of twelve genotypes of maize of different maturity-early, intermediate and late collected from the International Institute of Tropical Agriculture (IITA), Ibadan and IAR&T, Moor Plantation, Ibadan, respectively.  The experimental design used was completely randomize design (CRD) and data was collected for some viability and vigour traits and the data collected were subjected to analysis of variance. Significant differences were found among all the maize genotypes for the characters under observation. Hundred seed weight ranged from 24.6-29.3 g, 18.5-26.6 g, 22.9-29.1 g, standard germination ranged from 54.0-100.0%, 16.0-92.0%, 50.0-100% and accelerate ageing germination also ranged from 6.0-96.0%, 7.0-84.0%, 0-90.0% in the early, intermediate and late- maturing genotypes, respectively. Conductivity ranged from 5.34-17.10 µS/cm/g, 13.7-91.7 µS/cm/g and7.06-33.6 µS/cm/g with mean values of 11.14, 39.23 and 14.05 µS/cm/g in the early, intermediate and late-maturing genotypes, respectively. Variability was smaller in the late-maturing genotypes for Root Number (RN) and Shoot Length (SLT) but higher for both early and late- maturing genotypes. It was concluded from this study that seeds of early-maturing genotypes had significantly higher physical and physiological quality parameters.  All the early materials used for the study tend to be homogenous for all the traits measured and selection should be practiced for hundred seed weight to increase yield potential in maize varieties.

Determination of the optimum sowing window not only can improve maize yield significantly but also can fit maize in the existing cropping pattern. To get the advantages of sowing maize at the optimum time, a study was designed and carried out at the research field of Bangladesh Agricultural Research Institute, Rangpur, Bangladesh during 2015–2017. Another aim of the study was to forecast the yield of maize for the northern and western regions of Bangladesh using the CERES-Maize model. The study considered 5 November, 20 November, 5 December, 20 December, and 5 January as sowing dates for maize to identify the optimum sowing window. Three hybrid maize varieties, viz., BARI Hybrid Maize-9 (BHM-9), NK-40, and Pioneer30V92 were used. The study was laid out in a split-plot design, assigning the sowing dates in the main plot and the varieties in the sub-plot. To forecast the yield, the daily weather data of 2017 were subjected to run the model along with thirty years (1986–2015) of weather data. The genetic coefficients of the tested maize varieties were obtained through calibration of the model by using the observed field data of 2015–2016 and through validation by using the data of 2016–2017. The seasonal analysis was done using the DSSAT CERES-Maize model to confirm the experimental findings for optimizing the sowing window for maize at the northern region (Rangpur) of the country and subsequently adjusted the model for the western region (Jashore). The model performances were satisfactory for crop phenology, biomass, and grain yield. The NRMSE for anthesis was 0.66% to 1.39%, 0.67% to 0.89% for maturity date, 1.78% to 3.89% for grain yield, and 1.73% to 3.17% for biomass yield. The optimum sowing window for maize at the Rangpur region was 5 November to 5 December and 5 to 20 November for the Jashore region. The CERES-Maize model was promising for yield forecasting of the tested maize varieties. It gave a realistic yield forecast at approximately 45 days prior to the harvest of all the tested varieties. The study results are expected to be useful for both the farmers and the policy planners to meet up the future maize demands.

Improved maize seed is instrumental to deliver an Asian-style ‘green revolution’ for Africa. The paper reviews and makes a comparative analysis of the maize (corn) seed sector and its evolution in Kenya, Tanzania, Uganda and Ethiopia drawing from seed sector surveys and secondary data. Enhancing farmers’ access to and use of new maize varieties still presents a number of challenges in eastern Africa – not least due to a number of policy and institutional impediments to the development of the seed sector. The regional seed sectors also show some remarkable contrasts: they have evolved at different speeds and in different directions, driven by diverging agricultural growth opportunities and varying degrees of regulation, liberalization and restructuring. The paper reiterates calls for an enabling environment for private seed companies to evolve in order to serve the diverse farmer communities so that they benefit from existing and future improved maize seed opportunities.
