Hybrid Maize

The production of hybrid maize seeds at the field level can be done by farmers, with the main constraints being limited human resources and capital. For economic recovery during Covid-19 in 2020, the Gunung Mas district government launched a "Cash labor-intensive program" to the community. One of the groups, Sei Kurun farmer group, used it for an innovative and productive hybrid maize seed business. The goal is to grow group as breeder of hybrid maize seed, and empower farmers in a productive and sustainable manner. The method applied is in the form of cooperation and assistance between farmer groups, the Agriculture Service as a partner and prospective buyer of the seeds produced, and AIAT of Central Kalimantan as a companion for the application of technology. The results showed that cash funds for JH 37 hybrid maize seeds can be implemented on 3 hectares, and have produced 1.5 tons of F1 hybrid seeds, which are then sold through the District Agriculture Office program. with a profit of IDR 35,440,000. This farming is feasible with an R/C of 3.08, and becomes a profitable and sustainable farm, as well as a choice of model for using labor-intensive funds.

Abstract Adoption of hybrid seeds remains low in many low-income countries. We conduct a field-experiment designed to measure the effect of offering hybrid maize seeds for purchase during a time when potential customers have high liquidity. Working with a large buyer of agricultural commodities in Northern Uganda, we randomly offer smallholder farmers the opportunity to purchase certified hybrid maize seeds at the same time as they visit the buyers’ stores to sell crops from a previous harvest. 16% of those offered purchase hybrid seeds, and average adoption of hybrid maize among those offered increases by 8 percentage points compared to a control group who does not receive the offer. Among those who accept the offer, we see an increase in the propensity to plant hybrid maize of 50 percentage points. This effect is more pronounced for female farmers than for their male counterparts. Our findings suggest that providing access to certified agricultural inputs at the place and time of post-harvest sales is a promising strategy to increase input usage.

Shape And Size

Maize seed is characterised by a variety of shapes and sizes, which directly or indirectly affect physiological properties. The aim of the present study was to establish the significance of the seed shape and size on the first count and germination. The following eight hybrids were used as a seed material in the trial: ZP196, ZP260, ZP341, ZP360, ZP434, ZP677, ZP684 and ZP704. The traits of seed shape and size were observed under laboratory conditions. The seed mass, the first count and germination were determined. The genotype and the seed fraction significantly affected the variance of seed mass formation, R2≥0,911, while the significance of these factors for the first count and germination was small with the coefficient of determination of R2≤0.129 and≤0.298, respectively. The first count and germination were high (above 95%) in all sizes and all shapes of seeds. The lowest first count and germination were detected in SO (94.2; 95.1, respectively), while the highest values were determined in SSP (97.1; 98.0, respectively). The importance of seed germination was determined by the analysis of variance (p<0.05).

Abstract North Sulawesi is one of the areas with great potential in supporting the production and productivity of hybrid maize seeds. The land available for the cultivation of hybrid maize seeds is very wide, the requirements for agro-climatic are simple, the technology is readily available, so that the prospect of profits for the cultivator is quite large. Most of the maize farmers in North Sulawesi tend to use hybrid seeds. This is because the yield obtained is very high, however, the availability of hybrid seeds is very limited, even if available, the price is quite expensive. Farmers are currently still dependent on seed assistance from the Government. Production of seeds through breeder farmers as a solution in order to increase corn production. NASA 29 variety is a new superior variety derived from male parents G102612 and Mal 03 as female parents. The results of the interview showed that 86% of the 25 respondents of maize farmers gave an average rating score of 3.8. This shows that they really like the characteristics of the plant. The production data for NASA 29 seed candidates is 3.6 tons / ha. These results indicate that the prospect of hybrid maize seeding business is profitable for breeder farmers.

Hybrids and open pollinated varieties (OPVs) are two commercial maize seed types cultivated in Nigeria. Information on their response to mechanical damage during processing is limited. This study is thus aimed at assessing the response of hybrids and OPVs of maize seeds to mechanical damage which would facilitate fabrication of processing facilities suitable for either of the maize types. Six maize varieties: three hybids (‘New Kaduna’, ‘SDM-1’, and ‘JO-195’) and three OPVs (‘Sammaz 15’, ‘Sammaz 27’ and ‘Suwan-1-stry’) were used for the study. The seed samples were subjected to standard germination, seedling vigour analysis, accelerated ageing, conductivity and fast green tests. The result showed that all the hybrid seed varieties had more damaged seeds than their OPVs counterpart. Shoot length and root length were more affected than other parts of the seedling. There were differences in the magnitude of electrolyte leakage as well as in what time each seed type (hybrid or OPVs) passed through the phases with ‘JO-195’ having the highest rate of electrolyte leakage. Hybrid seeds had lower resistance to mechanical damage and poorer storability when compared with the OPVs. In the overall, for all the traits, ‘Sammaz 15’, the best among OPVs was more promising when compared with ‘SDM-1’ which was the best among hybrid varieties. Processing machine equipment and accessories that are suitable for hybrid seeds might be inappropriate for conditioning OPVs.

AbstractMaize starch is an important agricultural commodity that serves as food, feed, and a raw material for industrial purposes. It is organized into starch granules (SG) inside amyloplasts and is highly accumulated in endosperms. Maize hybrids exhibit heterosis over their parents. However, the parental effect on the size of SG in F1 hybrid seeds remains unclear. Here we compared the seed SG sizes among two parental inbred lines (Chang7-2 and Zheng58) as well as their reciprocal hybrids. SG was observed in situ and in vitro with SEM. The size of seed SG in hybrids was more like that of female parents, especially for large SG population. Thus, the control of SG size exhibits a maternal inheritance trend in the context of plastid (amyloplast) inheritance. Our results provide some insight on selecting parental inbred lines for breeding maize hybrids with different SG sizes.

Abstract: The evaluation of seed deterioration is very important to control the quality of the seeds stored. This study aimed to investigate the potential of fast ethanol assay for seed quality assessment of maize stored under different conditions. The first experiment was to determine the incubating temperature, incubating time, and amount of seed used in the assay. The results showed that the best protocol for the detection of headspace ethanol was incubation of 3 g of maize seed with 20% moisture content (wet basis) in a 20 mL gas chromatography vial at 70 °C for 1.5 h. The assay induced approximately 200-700 µg.L-1 of headspace ethanol, which was sufficient to identify seeds with different vigour levels. In the second experiment, the optimal conditions were used for quality assessment in aged maize seed stored for 12 months under different storage conditions. The increase in the ethanol production of stored maize seed under the controlled conditions (15 °C and 20% RH in the hermetic seal) was lower than under ambient conditions. The ethanol production levels of maize seed samples at the start of storage was significantly lesser than at six months storage (p < 0.05). The test limitations in deteriorated seed with different cultivars and ages will be discussed.

Molybdenum Concentration

Soil and foliar treatments to raise the concentration of molybdenum in maize grain were compared. Both methods raised molybdenum concentrations in the grain and leaves, but the foliar sprays were more effective. Spraying when the maize plants were 80 cm tall increased the molybdenum concentration in the seed more than earlier spraying when the plants were only 30 cm tall. None of the treatments affected grain yield or the nitrogen concentration in the grain or leaves. Foliar sprays should allow a reduction in the rates of molybdenum now needed to maintain adequate levels in certified hybrid maize seed.
