Nutrient Solutions

Five nutrient solutions were evaluated in the greenhouse to determine which solutions would allow detached culms of Pennisetum to produce seed. The genotypes tested originated from the hybridization of Pennisetum glaucum L. (Pearl millet) × P. pennisetum Schum. (elephantgrass). The solutions were water, Hoagland's, sucrose, sucrose + hydroxyquinoline sulfate (HQ), and Hoagland's + sucrose + HQ. Neither the water nor the Hoagland's solution supported high seed set. Although the sucrose solution enhanced seed production, the seeds were low in weight and did not germinate well. The best nutrient solutions were 2% sucrose + 0.02% HQ or Hoagland's + 2% sucrose + 0.02% HQ. The four genotypes used differed substantially in seed production, but all produced seed, with germination >25%. This result indicates that the cut-culm technique is a possible way of getting recurrent restricted phenotypic selection seed in Pennisetum hexaploid hybrids.

The Village

Donors have invested more than US$45 million in seed production projects in Niger during the past two decades. These investments have largely failed. Public seed systems consistently supplied less than 2% of the total national seed planted by farmers. Through subsidies, seed prices represent less than one-third of the average cost of seed production. In contrast, at the village level, most farmers consistently obtain pearl millet (Pennisetum glaucum) seed from their own harvests, from neighbours or from village markets. Seed is of acceptable quality and a range of varieties is available. Village seed systems offer a cheaper and more efficient means of delivering seed to farmers. Future investment in seed systems development should target improvements in the capacity of village seed systems to maintain and distribute seed security stocks in drought years. Efficient seed producers or groups of farmers in each community should be identified and encouraged to become entrepreneurs tasked with the multiplication and distribution of new pearl millet varieties.

Abstract Pearl millet (Pennisetum glaucum) is considered an important kharif crop, which is grown extensively in the arid and semi-arid tropical regions, where other crops, like sorghum and maize, fail to produce economic yields. Its grains are valued as human food, while its dry stover makes significant livestock ration in croplivestock farming system. Pearl millets (MB-87), a newly developed variety of Fodder Research Institute, Sargodha, Pakistan, is one of the best pearl millet variety, which gives more than one cutting and helps to cope with fodder lean period, as well as more income can be generated in addition to seed. So, overcome the scarcity period the study was conducted to check the effect of last cutting dates on seed production of multicut pearl millet MB-87 was conducted at Fodder Research Institute, Sargodha, Pakistan, during 2015 and 2016. Following parameters were taken in to consideration, i.e. plant height (cm), stem thickness (cm), number of leaves per tiller, number of tillers per plant, green fodder yield (t/ha), length of head (cm), 1000 grains weight (g) and grain yield (kg/ha). The results depicted that grain yield, i.e. 319.20, was maximum and head length was highest, i.e. 35.13 cm on 20th of August having last date of cut, whereas all others parameters were found to be nonsignificant. Multicut bajra gives three cutting of fodder, followed by seed, as compared with conventional bajra, which gives only one cutting or seed. Therefore, it is more economical for the growers of fodders to grow the pearl millets MB-87 as fodder, as well as for seed purposes. So, it is concluded that for gaining maximum grain yield of multicut pearl millet MB-87 the last cutting date should be 20th of August. In future, pearl millet is likely to play a larger role in providing food and nutritional security.

Pearl millet (Pennisetum glaucum) is a staple food crop in Burkina Faso that is widely grown in the Sahelian and Sudano-Sahelian zones, characterised by poor soil conditions and erratic rainfall, and high temperatures. The objective of this study was to document farmers’ perceptions of the prevailing constraints affecting pearl millet production and related approaches to manage the parasitic weeds S. hermonthica. The study was conducted in the Sahel, Sudano-Sahelian zones in the North, North Central, West Central, Central Plateau, and South Central of Burkina Faso. Data were collected through a structured questionnaire and focus group discussions involving 492 participant farmers. Recurrent drought, S. hermonthica infestation, shortage of labour, lack of fertilisers, lack of cash, and the use of low-yielding varieties were the main challenges hindering pearl millet production in the study areas. The majority of the respondents (40%) ranked S. hermonthica infestation as the primary constraint affecting pearl millet production. Respondent farmers reported yield losses of up to 80% due to S. hermonthica infestation. 61.4% of the respondents in the study areas had achieved a mean pearl millet yields of <1 t/ha. Poor access and the high cost of introduced seed, and a lack of farmers preferred traits in the existing introduced pearl millet varieties were the main reasons for their low adoption, as reported by 32% of respondents. S. hermonthica management options in pearl millet production fields included moisture conservation using terraces, manual hoeing, hand weeding, use of microplots locally referred to as ‘zaï’, crop rotation and mulching. These management techniques were ineffective because they do not suppress the below ground S. hermonthica seed, and they are difficult to implement. Integrated management practices employing breeding for S. hermonthica resistant varieties with the aforementioned control measures could offer a sustainable solution for S. hermonthica management and improved pearl millet productivity in Burkina Faso.

Summer cover crop rotations, compost, and vermicompost additions can be important strategies for transition to organic production that can provide various benefits to crop yields, nitrogen (N) availability, and overall soil health, yet are underused in strawberry (Fragaria ×ananassa) production in North Carolina. This study was aimed at evaluating six summer cover crop treatments including pearl millet (Pennisetum glaucum), soybean (Glycine max), cowpea (Vigna unguiculata), pearl millet/soybean combination, pearl millet/cowpea combination, and a no cover crop control, with and without vermicompost additions for their effects on strawberry growth, yields, nutrient uptake, weeds, and soil inorganic nitrate-nitrogen and ammonium-nitrogen in a 2-year field experiment. Compost was additionally applied before seeding cover crops and preplant N fertilizer was reduced by 67% to account for organic N additions. Although all cover crops (with compost) increased soil N levels during strawberry growth compared with the no cover crop treatment, cover crops did not impact strawberry yields in the first year of the study. In the 2nd year, pearl millet cover crop treatments reduced total and marketable strawberry yields, and soybean treatments reduced marketable strawberry yields when compared with the no cover crop treatment, whereas vermicompost additions increased strawberry biomass and yields. Results from this study suggest that vermicompost additions can be important sustainable soil management strategies for transitional and certified organic strawberry production. Summer cover crops integrated with composts can provide considerable soil N, reducing fertilizer needs, but have variable responses on strawberry depending on the specific cover crop species or combination. Moreover, these practices are suitable for both organic and conventional strawberry growers and will benefit from longer-term studies that assess these practices individually and in combination and other benefits in addition to yields.
