Increasing the Production and Productivities of Groundnut in the Dry Savannas of West Africa Through Appropriate Crop Production Practices

  1. Nigeria has move from one of the major groundnut exporting country to an impor- ting country due to several factors, biotic, abiotic ad social. There is a renewed interest by stakeholders to increase groundnut production in Nigeria. One way is to increase the hectrage of production either in the wet season or through dry season production. Preliminary survey have shown that groundnut cultivation in the dry season for seed, grains or fodder is highly profitable. There is however no scientifically backed recommendation of planting date and variety for this technology. Farmers therefore plant dry season groundnut whenever they fill, some farmers plant too early resulting in stunted growth as a result of low temperature in the early season while others plant late which result in the crop maturing at beginning of rains thereby resulting in conflict with the subsequent wet season crop. This can be addressed by initiating a scientific based research to obtain optimum planting date dates. Another way to increase the groundnut production is to improve the agronomic recommendation to facilitate reaching potential yields of the new improved varieties available. • baCkground • To identify optimum planting date and • To identify suitable varieties for profitable groundnut cultivation under irrigation in the dry season in Sudan savanna of Nigeria • To evaluate the response of two contrasting groundnut varieties to P application and increased plant population. • objeCtives A. Dry Season Planting dates • Two locations were selected for the experiment in the Sudan savanna • 11 planting dates • 5 groundnut varieties were planted at two weeks interval from end of the raining season to two months before the establishment of rains. • Improved agronomic practices were deployed in planting and field maintenance B. Effect of Fertilizer and Plant Population • Samnut-22 and 24 varieties of groundnut were used for the experiment, with two fertilizer levels (45 and 0 kgha-1 P2O5) • plant population of 133,333; 66,667 and 44,444 plants per hectare, • laid out in a Split-Split Plot Design with four replications • metHodology • Early planting (October to December) increases days to maturity (132 to 150 days) compared to planting in January to March (100 to 123 days), • Early planting also produced lower pod yields (1262 to 2342 kg/ha) compared to planting in January to February (2018 to 2447 kg/ha). • P fertilizer application increased pod and haulm yields by 26% to 62% and 16% to27% respectively. • Pod yields at spacing of 10 x 75cm was 31% higher than at 20 x 75cm and 40% than at 30 x 75cm . • Application of fertilizer increased profit by 22% to 49%. • results and main aCHievements • Current and PartnersHis future engagements for out sCaling • Groundnut can be profitable cultivated in the dry season under irrigation in the Sudan savanna of Nigeria • Pod and haulms yields observed in the dry seasons were significantly higher than what was obtained in same locations in the wet season • Planting should be completed by mid February to ensure high yields and harvest before establishment of rains. • There is a need to adjust the population recommended for the cultivation of groundnut in the Sudan Savanna of Nigeria. • Both medium and early maturing varieties responded positively to increased plant population. • Pod and haulm yields of over 2.4 t ha-1 are possible under higher plant popula- tion with appropriate P fertilizer application. • P fertilizer application was also found to be necessary for increased grain yield and profitable groundnut cultivation and should be recommended • ConClusions The results is being deploy to produce groundnut seeds by both TL3 and Groundnut Upscaling Projects in Nigeria. Currently the results is being used to produce dry season groundnut in 7 states in Nigeria. The results of the fertilizer and plant populations was recently presented before the Institute for Agricultural Research Cropping Scheme meetings with a view to change the National Groundnut Crop Production Recommendation.
