This work performs a review of the relevant aspects of agronomic dynamics of phosphorus (P) in the soil–plant relationship as a community (crop ecophysiology), the effect of environmental conditions and global warming on the redistribution and translocation of P in some crop, and the use of good agricultural practices with the aim of improving the efficiency of the element. The research focuses on Northern Europe, North-Eastern Asia, Oceania, North America, and the tropical area of Latin America. This review covers general research and specific works on P found in the literature, 70% of which date from the last 10 years, as well as some older studies that have been of great relevance as references and starting points for more recent investigations. The dynamics of P in a system implies taking into account genetic aspects of the plant, component of the soil–plant–fertilizer–environment relationship, and use of technologies at the molecular level. In addition, in a climate change scenario, the availability of this element can significantly change depending on whether it is labile or non-labile.

“…Considerando apenas o nutriente fósforo, um aumento de número de vagens por planta também foi observado por Bezerra et al (2018), que estudando características de feijão-caupi submetidas a diferentes níveis de P, observaram um aumento de 168,4% no número de vagens por planta, comparando o tratamento com a máxima aplicação de P2O5 (240 kg ha -1 ), com o tratamento controle (sem aplicação de P2O5). Segundo os autores, o número de vagens por planta é o principal componente de produção do feijão-caupi.…”

RESUMO:A deficiência hídrica e a falta de adubação são fatores limitantes na produção de feijão-caupi, especialmente no Nordeste Brasileiro, onde a maioria dos cultivos são de subsistência realizados pela agricultura familiar. O objetivo deste trabalho foi avaliar o desempenho da cultivar de feijão-caupi 'BRS Novaera' cultivada em vasos submetida a diferentes níveis de irrigação e adubação em ambiente protegido. O experimento foi conduzido em blocos casualizados, com três repetições no esquema fatorial 4 x 2, com quatro níveis de irrigação (40%, 60%, 80% e 100% de irrigação para capacidade de vaso) e dois níveis de adubação (com e sem uso de adubos a base de nitrogênio (N), fósforo (P) e potássio (K)). Nas condições estudadas, observou-se que a maior produtividade de grãos foi obtida com 72% de irrigação para capacidade de vaso e que a adubação NPK resultou em incremento no número de vagens por planta de 105,5% e produtividade de grãos de 135,7%.

ABSTRACT:Water deficiency and lack of fertilization are limiting factors in the production of cowpea, especially in the Brazilian Northeast, where most of the crops are cultivated for subsistence farming. The objective of this work was to evaluate the performance of 'BRS Novaera' cowpea cultivated in pots, under different irrigation levels and fertilization in a protected environment. The experiment was conducted in a randomized block design with three replications in a 4 x 2 factorial, with four irrigation levels (40%, 60%, 80% and 100% irrigation of pot capacity) and two fertilization levels (with and without nitrogen (N), phosphorus (P) and potassium (K) fertilizers). Under the conditions studied, it was observed that the highest grain yield was obtained with 72% irrigation for pot capacity and that NPK fertilization resulted in 105.5% higher number of pods per plant and 135.7% higher grain yield.

“…Due to increasing popularity, an estimated 8.81% of total pulse production area is used for cow pea production in Bangladesh (BBS, 2020) which shows very encouraging results in the pulse production. Cowpea grain contains up to 25% protein and it is a good source of carbohydrate, vitamins, amino acids like thiamine and niacin, various minerals and dietary fiber (Bezerra et al, 2018;Boukar et al, 2019). Cowpea also plays an important role in providing soil nitrogen through symbiosis with specific bacteria.…”

Indiscriminate use of inorganic fertilizer changes the physical, chemical and biological properties of soil as well as reduces soil fertility status. The decline in soil organic matter content is a major process of soil fertility reduction. Organic amendments can augment soil fertility. For this, a pot experiment was conducted to investigate the effects of various organic amendments (bagasse, bio-slurry, and kitchen waste compost) in comparison with chemical fertilizer on the growth, yield and nutrient status in the shoot and root of cowpea plant. Soil was treated with respective organic amendments at the rate of 5t/ha. Five cow pea seeds were sown in each pot. The experiment was laid down in a completely randomized design with three replications. Results indicated that all organic amendments influence the growth and yield attributes of cow pea plant. Fresh weight, dry weight and pod yield of the plant greatly enhanced by the application of bio slurry which accounted 2.5 times higher pod yield as compared to inorganic fertilizer. Root growth was improved with the application of bio slurry whereas kitchen compost had positive effects on root length, root diameter and root length density of cow pea plant. Nutrient (N, P and K) content and uptake in shoot of cow pea plant did not vary significantly with organic amendments except root. In addition, variable nutrient use efficiencies were recorded in shoot and root of the plant with the applied organic amendments. Sustainable agricultural production system requires improved soil health to increase crop production. Therefore, it is suggested to use these organic amendments with the attention given to the bio-slurry to achieve a long term sustainable agriculture system.
