Therefore, farmers will usually make use of seasonal workers. The country is surplus producing in the commodity. constraints and high prices for improved maize and fertilizer are limiting adoption, however, and continue to be a challenge for sustainable intensification of the maize-based production system. ��;���!|�[�����&I��պm��]�=�Ad���r�+�^)r�V:K���������c��l�.G)-�M)r�o��ۉ����A[U@��Ϻ�v�O���Uq۔_��o��9։I����h��U����2�����}�NC�o�˲|h9z6���^��8����WG?����wW���l�C��GEq����~���գ�ű��͊e�7��RD�,�zqu��ӈ���F+ �5�mf�Ͳ�Z�5��eQ�ۈ�h� |�a��@�* �+D�o٠7�s��=��]�g����I(+/ ��I�-w��Vu�+���;Q�T��q���E�ϻ�^y+���){졮�B-�C� Other non-inputs factors include better targeting, proximity advisory services, etc. Fertilizer Use in Maize in Zambia Data on fertilizer use in maize in 2011 reveal that Zambia has the highest fertilizer (NPK nutrients) application rate in Sub-Saharan Africa 4. 2009). The effects of metalachlor (as DualTM Magnum 960 EC), a pre-emergence herbicide, with 69N:21:P 2O 5:4S kg ha-1 and without fertilizer application, on maize growth and Striga The crop is cultivated in all five NRs, NRs II and III accounting for about 84 percent of total maize production. Botany of Maize Chapter 4. convectional fertilizer Dap and Urea and also control plots. In central Malawi, Kamanga et al. In addition to the effect of chemical fertilizer, it should be noted that the introduction of improved strains helped double the unit yield. Applying fertilizer • Maize needs enough nitrogen and phosphorus. Maize is susceptible to both drought and water-logging. One‐time application of multi‐nutrient fertilizer briquettes increased maize grain yields. MAIZE PRODUCTION MANUAL VOLUME I CHAPTERS 1-9 APRIL 1982 Published and printed at Intemationallnstitute of Tropical Agriculture Oyo Road, PMB 5320 ~badan, Nigeria Manual Series No. Physiology of Maize Chapter 5 Maize … Figure 1: Elasticity, percentage variation of maize production for a 1% increase in soil loss, by agroecological zone 24 Figure 2 - Expected delta maize productivity for 22 tons/ha (left) and 40 tons/ha (right) in % w.r.t. Successful cultivation of maize depends largely on the efficacy of weed control. However, though maize output has increased due to FISP, micro-level food insecurity is widespread and diets are poorly diversified (Bezner Kerr, 2013; Mazunda, Kankwamba & Pauw, 2018). Overall, fertilizer use is found to be the single most important factor in increasing maize yield under S. asiatica infection, while herbicide use is important for reducing emergence. Effects of fertilizer application, tillage, crop residues and herbicides on maize yield in Manjawira, Mpingu and Ziydana Extension Planning Areas, central Malawi. maize/bean, maize/groundnut, etc (Snapp et al. Maize is the main staple food in Zimbabwe. Zea mays Corn, Indian corn, mealies. for students only. maize farmers in southern Malawi. [27] used the APSIM–model as a decision support-tool for improving the efficiency of the use of small amounts of nitrogen and phosphorus fertilizer on smallholder maize. Wheat and maize production in China was 121.7 and 217.8 million tons in 2013, approximately 17.1% and 21.4% of global output, respectively [27]. Kaiyare 1, and G.N. Sources of Technical Efficiency among Smallholder Langyintuo L (2011b). Research on fertilizer programmes has been stressed, a further work by Khan et al. Traditional practices affecting soil fertility have variable effects on soil fertility and crop productivity. Table 2 presents a comparison of fertilizer application rates on maize for Zambia and its neighboring countries. Maize production in Malawi is limited by high costs and sub-optimal use of chemical fertilizers under continuous cultivation. production grew at 1.9% per year. In recent years there has been a trend among maize growers to apply Calcium Ammonium Nitrate (CAN) fertilizer to their crops in preference to Urea. The parasitic weed species Striga asiatica (L.) Kuntze is one of the major constraints in maize production in Malawi. Despite decades of agricultural policies that promoted the adoption of fertilizer and hybrid seeds technologies as a way of improving maize productivity, technology adoption rates in Malawi remain relatively low among smallholder farmers. Proceedings of the Fourth Eastern and Southern African Regional Alaize Conference on “Maize Research for Stress Environments”, Harare, April, 1994. efficiency of the bottom half of farmers to that of the mean could raise national maize production by as much as 8 to 11 percent without any additional use of fertilizer (Xu et al. Malawian officials Newly introduced conservation technologies appear promising as one way to reduce the vulnerability to drought and enhance the fertilizer use efficiency. allocations to maize production suggests wide agreement that maize is central to wellbeing in Malawi. The coefficient of amount of chemical fertilizer used for maize production indicates that a 1% increase in the amount of fertilizer usage for maize production leads to 0.12% increase in the maize yield per hectare. Methods of fertilizer application. The effect of sole maize and green manures (Mucuna pruriens, Crotalaria juncea and Lablab purpureus) on maize for two successive cropping seasons was determined in on-farm experiments at five locations in Malawi from 1996 to 1999.Legume residues were incorporated at two different times; ‘early’ at peak biomass and ‘late’ when the plants started to senesce. This result is similar to the result found by . China takes the first and the second positions, respectively, in global wheat and maize production. ޻f|Gr���b��]���"�b{(Ym��Da�H�Y��=IR����D1I�a�6���=J�D��>.ǣ��S��/��+̗� �cȗ�[���!_(�%1ݐ|)����u�\/��_�L�P��(�$~��bݒ=�VQ��ޜ�""�韡�����g�O�aQ�W��� ໋�OQ~�2��i)a!^O��_����E�/��]U.�,��SűN�SZ�rݩx��J�6������g(�l��_��5�˴d�A�J�jf��iҰ�"� �3��€�~a�v�s • Read the information on the maize packet to know the emergence rate, expiry date, and the area where the maize is to be grown.

Activities include the following: Establishing a natural resources data base for Malawi; matching appropriate maize cultivars for the agroecological zones of the country under varying management inputs; and updating site-and season-specific fertilizer recommendations in the primary maize-growing agroecological zones of the country. The subsidies and free distribution of seed and fertilizer encouraged maize production by smallholders (Chinsinga, 2011) and harvests surpassed those of previous years turning the country from a recipient of food aid into a food exporter and food aid donor to neighboring countries. Regardless of tillage method, fertilizer application significantly increased maize and soybean grain yields. The poor performance of the agricultural sector in Malawi, including maize production, is partly because of low yields and stagnating productivity growth. The average annual national maize consumption is estimated at over 3m metric tons (MT) (USAID, 2017), while production in 2016 was 5.9m MT harvested from 4.0m ha with a productivity of 1.46 t/ha (FAO, 2018). Many fertilizer types were used for maize production such as: urea, diammonium phosphate (DAP) and various NPK forms (Adégbidi et al. a baseline scenario of 10 kg/ha 24 Figure 3 - Impacts of soil loss by representing the elasticity values for maize production, Thus, while fertilizer use may be profitable many households are cash constrained and may fail to buy the inputs at commercial prices (Holden and Lunduka, in press). fertilizer use in maize production is unattractive to many smallholders at current maize price to fertilizer cost ratios relative to other uses of available finance. AGRO 513 . 1998a). The purpose of the study was to assess the performance of a gliricidia/maize intercropping system as a low-input soil fertility replenishment option in southern Malawi. Furthermore, to be efficient in terms of crop yield improvement under farmer conditions, high yielding varieties must be used. The parasitic and 0.88 for the maize varieties used. The lower volatilization risk in dry soils and the perceived neutral effect on soil acidity has encouraged the trend, along with the subsidized price through the National Cereals Produce Board (NCPB). We estimate the effects of conventional production inputs as well as of household characteristics and government programs on maize yield. Effects of fertilizer application, tillage, crop residues and herbicides on maize yield in Manjawira, Mpingu and Ziydana Extension Planning Areas, central Malawi. CONT… White maize is the most important cereal in Tanzania, accounting for about 70% of annual cereal production (GoT, 2018). Farmers often apply fertilizer to a sole maize crop. The standard fertilizer recommendation for maize consists of 150 kg ha −1 NPK 14–23–14 and 50 kg ha −1 urea (Dugué 2010). For more information see the Pioneer Technical Insight No 315: Cultivating Peat Soils. … Fertilizer application was done by researcher team. In some farming seasons, maize production process will require increased labour given the importance of harvest. Maize grows best on deep, well-drained, fertile soils, and where total seasonal rainfall exceeds 500 mm. x�ݝٶEv���S�]���ʚ�i6c3�m�W�h��� ����[��232����̪sFH:��aǎ=ǎ��f����-�_���\�t������W?���U���K���'�?�9V;6:��ٝGW�Ӈ�l����~�)fw�\�5{���U����j�v5߮g����X~�V������n��W�/+l�}��Ge�(;�����.|W}\�������o��w��i��,o��3t�IU�|��_����s� ,�`�9�_������!�N�Z��S��}Y��q��5����i���f��@�w���>��S���_c���,��,� Byerlee and Heisey (1996) made an economic analysis of alternative maize technologies in Malawi assuming that hybrid maize with 145 kg fertilizer nutrients per ha would give a maize yield of 2400 kg/ha while local maize with 55 kg fertilizer nutrients per ha would give a maize yield of 750 kg/ha. Yield gap analysis of major food crops in Pakistan: prospects for food security. 2000; Acakpo 2004). The objective of this paper is to highlight on the effects of complementary applications of organic and inorganic fertilizer on the production of maize in Nigeria. These inputs are, inter alia, adapted cultivars, plant population, soil tillage, fertilisation, weed, insect and disease control, harvesting, marketing and financial resources. Micronutrient deficiency is seldom a problem in maize crops however deficiencies sometimes occur on light or peat soils. (2003) report shows that different maize cultivars differ in response to N fertilizer application. Application of fertilizer to soybean resulted in 59% (193 kg ha−1) and 54% (474 kg ha−1) increase in grain yields in 2013 and 2014, respectively, over no fertilizer treatment. 3. By September 2018, the price of maize was set by the Malawi government at 170 Kwacha ($0.23) per kilogram. A study from 2003 showed that in Malawi, the smallest farms—under one hectare— Njihia 1, Z. Saitoti1, J.M. But it may be more profitable to apply fertilizer to an intercrop of maize and a grain legume, e.g. Maize production in Malawi is limited mainly by low soil N and P. Improved fallows of N-fixing legumes such as Tephrosia and Sesbania offer options for improving soil fertility particularly N supply. Such … Reports demonstrate an average of 160 kg/ha total fertilizer spread across all crops, with 35 or 69 kg/ha of N fertilizers. Intercropping with one or more legumes is common in Malawi, with maize being the dominant crop, and the legume(s), generally planted at õšëêIȘùI)/P -1340/R 4/StmF/StdCF/StrF/StdCF/U(§g/†•ì¥\r÷«Ï$m )/V 4>> endobj 259 0 obj <. The coefficient of amount of chemical fertilizer used for maize production indicates that a 1% increase in the amount of fertilizer usage for maize production leads to 0.12% increase in the maize yield per hectare. Key words: Striga asiatica, imazapyr, Zea maize (L), Malawi, acetolactate synthase. (1989) reported an increase in plant height when nitrogen fertilizer was applied to three maize cultivars.

When potashic fertilizers like muriate of potash and potassium sulphate are to be applied in potash deficient soil. In the 35 years during 1970–2005, there have been only marginal increases in maize and rice productivity MoAFS, 2011). When planting maize on run-out peat pasture the application of 150 - 200 kg/ha of Sulphate of Ammonia is recommended. Importance of Maize in Africa, Chapter 3. Fertilizer application has risen tremendously through the 1990s.In 2005/6, as a result of a poor harvest in 2004/5, the government decided to implement a fertilizer subsidy to promote accessibility and use of fertilizers in maize production in South Afri, 22: 1-12. 8 0 obj Assuming the recommended fertilizer rate for maize on a hectare is 3 bags of NPK 15:15:15 using the right application rate; you can end up using 6 bags because you do not know how to calculate the fertilizer application rate for NPK 15:15:15, hence, you have ignorantly increased the cost of your maize production. Chapter 1 is an analysis of the determinants of maize yield response to fertilizer applications using longitudinal data collected in 2004 and 2008 from 7,127 smallholder maize fields. The results indicate that recommended fertilizer application rates in the two specific years were often unprofitable, given observed price conditions and the yield response to fertilizer. For example, some places report using 87 kg of Di-ammonium Phosphate (DAP) fertilizer and 175 kg of urea fertilizer per hectare for hybrid maize. exhausted by previous crops like maize, pearl millet. Maize became increasingly important in the food security of Ethiopia following the major drought and famine that occurred in 1984. Maize yield is an average over three seasons. Kassie GT, Erenstein O, Mwangi W, La Rovere R, Setimela P, Chirwa EW (2007).

Successful cultivation of maize depends largely on the efficacy of weed control. • Using the right seeds ensures good germination. production of maize, the main staple crop, with 1.2 million hectares of production annually, occupying about 80% of cultivated land. The average annual national maize consumption is estimated at over 3m metric tons (MT) (USAID, 2017), while production in 2016 was 5.9m MT harvested from 4.0m ha with a productivity of 1.46 t/ha (FAO, 2018). Maize production in Malawi is limited by high costs and sub-optimal use of chemical fertilizers under continuous cultivation. Research findings by Arain et al. Composite soil samples were collected at 0–20 cm depth after plowing and before fertilizer application. Test for micronutrients. 2018 saw the price of maize spike multiple times, from 100 Malawi Kwacha (US$0.14) per kilogram to 140 Kwacha ($0.19) per kilogram in 2018. Successful maize production depends on the correct application of production inputs that will sustain the environment as well as agricultural production. fertilizer to improve maize production in on-station and on-farm experiments in central Kenya. • You will need 10 kg of maize per acre (25 kg per hectare). At the same time, maize production in Malawi decreased 20% in 2018. Values designated by the same letter at each study location are not significantly different from each other. Agricultural Economics, Vol.51, No.6 3 October 2020. High nutrient recovery efficiency of fertilizer briquettes resulted in a 25% reduction in application rates. A grain with a high germ content. The application rates for these fertilizers vary a lot throughout the country. The maize have also confounded the adoption process adoption of improved, higher yielding maize varieties has (Chinsinga, 2011).
