Thirty four genotypes of pearl millet( Pennisetum glaucum (L.) R. Br) were evaluated at Sudan. Including two released varieties, Ugandi and Ashana at Gezira Research Farm (GRF) and Rahad Research Farm(RRS) in the autumn of 2009. The experiment was arranged in randomized complete block design with three replications. Grain yield and some yield components including number of productive tillers and panicle length, varied significantly among the thirty four genotypes. Mean of grain yield for all genotypes across sites was 1.3 t/ ha-1. Sadag Togo had the highest grain yield (1.7 ha-1) followed by Okashana-3 (1.6 t/ha-1), while IP 19745 had lowest grain yield (0.8 t/ha-1) across tow site.Okashana-3 out yielded the best than check (Ashana). The combined Result for Genotypic coefficient of variability and broad sense heritability estimates grain yield and head weight varied significantly among the thirty four genotypes.

<p>Effects of planting dates on the growth and grain yield of two indigenous varieties of pearl millet was carried out at the Teaching and Research Farm, Ambrose Alli University, Ekpoma. The experiment was a 2 × 5 factorial scheme fitted into a randomized complete block design with the two varieties of pearl millet (‘Gero Bida’ and ‘Gero Badeggi’) and five planting dates (April, May, June, July and August) replicated three times. The results obtained showed that delays in planting date significantly reduced growth in pearl millet examined. Similar pattern was observed on days to 50 % flowering and grain maturity. Improved growth with early sowing could have allowed increased availability of assimilates that later supported reproductive growth. These assimilates were remobilized under unfavourable climatic condition in the late cropping season to the reproductive structures. ‘Gero Badeggi’ sown in April, had significantly, the highest growth in the measured characters than ‘Gero Bida’ sown in August and other dates. ‘Gero Badeggi’ planted in May had the highest total grain yield (9.33 t ha<sup>-1</sup>) while ‘Gero Bida’ planted in July had the smallest (4.27 t ha<sup>-1</sup>). Therefore, ‘Gero Baddegi’ planted in May is a better variety for pearl millet grain production in Ekpoma.</p>

The 27 accessions of pearl millet of African origin were studied during <italic>kharif</italic> 2013 and 2014 in a randomized complete block design in the hot arid climate of Rajasthan. The study was conducted to assess the magnitude of presence of genetic variability and associations among characters namely, grain yield per plant (gm.), number of tillers per plant, plant height (cm), panicle length (cm), panicle diameter (cm), number of leaves per plant, days to 50% flowering and test weight(gm.). The result showed that genetic variability was present among the accessions for all studied characters. The estimated PCV (%) and GCV (%) were high for all characters. The broad sense heritability (%) and genetic advance (% of mean) estimates were also high for all studied characters. The number of tillers per plant, panicle length (cm), panicle diameter (cm) and days to 50% flowering had positive and significant genotypic, phenotypic and environmental correlation coefficients with grain yield per plant. The presence of genetic variability, high heritability and genetic advance and association with grain yield of number of tillers per plant, panicle length (cm), panicle diameter (cm) and days to 50% flowering amenable them for selection and enhancement of grain yield.

An experiment was carried out at Bangladesh Agricultural University, Mymensingh to evaluate the effect of urea super granule (USG) as a source of nitrogen on the yield and yield components of transplant Aman rice cv. BRRI dhan39, BRRI dhan46 and BINA dhan7. Five levels of N (viz., 0, 60, 120 kg ha-1 as prilled urea and 60 and 120 kg ha-1 as USG) were taken as experimental treatments. The experiment was laid out in a randomized complete block design with three replications. Plant height, effective tillers hill-1, grains panicle-1 and grain yield varied significantly due to different cultivars. All the yield and yield components except 1000-grain weight were influenced significantly by the levels of nitrogen fertilizer. The highest grain yield (4.82 t ha-1) was recorded in BINA dhan7 and the lowest one (4.30 t ha-1) was recorded in BRRI dhan39. Nitrogen @ 120 kg ha-1 as USG performed the best among the treatments in respect of yield and yield components of rice. The highest grain yield (5.46t ha-1) was obtained from BINA dhan7 with 120 kg N ha-1 as USG which was statistically identical with 60 kg N ha-1 as USG. A considerable amount (31.25%) of prilled urea (PU) nitrogen could be saved by using USG. It may be concluded that USG could be used as N management to achieve better nitrogen use efficiency in reducing N loss than the PU.DOI: http://dx.doi.org/10.3329/pa.v24i1-2.19095 Progress.

Physical Attributes

Hybrid rice technology is one of the promising, sustainable, and proven technologies for increasing rice production and productivity with a yield advantage of 15–30% over modern inbred varieties. The potential of hybrid rice has so far not been exploited in Ghana. This study was undertaken to evaluate the yield potential, reaction to diseases, and physical grain attributes of some introduced hybrids. The trials were laid out in a randomized complete block design (RCBD) with three replicates across three locations. Data were taken on grain yield, yield components, reaction to diseases, and grain physical characteristics. Four promising hybrids (SWARNA 2, ARGH 1501, ARGH 1502, and ARGH 1503) with a mean yield advantage of 15–20.8% over the best inbred check “AgraRice” were identified. With few exceptions, the hybrids were broadly adapted and had adequate resistance to blast and bacterial leaf blight. Most of the test hybrids had long slender grains which make them acceptable to the Ghanaian market but lacked aroma.

The trials were conducted in 2010 and 2011 rainy seasons at Usmanu Danfodiyo University, Sokoto Teaching and Research Dry Land Farm, Dundaye, Nigeria to determine the effects of variety and nitrogen levels on performance of  (SOSAT c-88 and Zango millet varieties). Data collected were on Stand count, tiller count, plant height and panicle length. Others included panicle weight and grain yield. All data collected were subjected to analysis of variance (ANOVA). The results SOSAT c-88 and Zango millet indicated that millet varieties have no significant effect on both stand and tiller production throughout the sampling periods though nitrogen levels has significant on tiller production at 6 weeks after planting of both 2010 and 2011 cropping seasons. Panicle length was affected by millet varieties and nitrogen levels in both cropping seasons. Improve millet variety Sosat c-88 gave higher grain yield while 80 kg ha-1 and 120 kg ha-1produced significant higher millet grain yield hence should be practiced. Doi: 10.28991/HEF-2020-01-04-04 Full Text: PDF

A series of tropical maize hybrids, involving 10 single, four double and four three-way crosses were evaluated with their parental inbred lines and three control varieties, at Universiti Putra Malaysia, Serdang, Malaysia, in a randomized complete block design, with three replications. The objectives were to identify hybrids superior for yield, yield components and other agronomic traits, to estimate heterosis revealed by the hybrids, and to estimate broad-sense heritability for important characters in the populations. The hybrids were found to vary highly for grain yield and most other traits measured. High estimates of heterosis were shown by grain yield, ear weight and grain weight per ear, moderate for plant and ear heights, shelling percentage, ear diameter, number of kernel rows per ear, number of kernels per ear row and 100-grain weight. The hybrids flowered and matured earlier than their respective inbred parents. Estimates of broad-sense heritability also varied with characters. Moderate heritability was shown for grain yield indicating a substantial amount of genetic variation in this population of hybrids. Low and negligible heritability for days to silking and 100-grain weight indicate that these traits were very much influenced by environmental factors. Based on the overall performance of the hybrids, the single cross, SC-2, the double cross, DC-11 and the three-way cross, TWC-15, were found to have high potential. No obvious differences were observed in performance among the three categories of hybrids, the single, double and three-way crosses.

Phosphorus Levels

Phosphorus is one macronutrient that commonly gets fixed and accumulates into soils after it has been in use for long, thus becoming readily unavailable to plants in subsequent years. Such scenario is ontological in Mwea where rice farming is practiced, yet this element is one main critical nutrient that plants cannot do without for they need it for root initiation, root development, photosynthesis, grain- formation, grain-filling, as well as yielding. In that view therefore, an experiment was undertaken in Mwea irrigation scheme with the aim of investigating on the influence of phosphorus levels on yield components and grain yield of Nerica 4 and 11. The experiment was laid out in a Randomized Complete Block Design in split-plot arrangement replicated thrice. Two rice varieties (Nerica 4 and Nerica 11) formed main plots and phosphorus levels (0 kg P/ha, 25 kg P/ha, 50 kg P/ha and 75 kg P/ha) formed split plots. Data was collected on appropriate parameters between week 4 and 19 after sowing at intervals of three weeks. Results demonstrated that phosphorus levels significantly influenced the 1000-grain weight and number of panicles in the tested varieties. Additionally, Grain yield mean variation was observed, where highest grain yield of 0.988 tons per hectare was produced in Nerica 4 on 50 kg P/ha in season 2, while least grain yield of 0.831 tons per hectare was still produced in the same variety on control in season 1, thus 50 kg P/ha on Nerica 4 is recommended for rice farming in Mwea. The study would be used as a body of guidelines and information for judicial, responsible, and promotion of prescribed application of phosphates in Nerica rice farming at planting for realization of higher yields between the two Nerica varieties (Nerica 4 and 11) in Mwea and with like agro ecological areas.
