There is a lot of discussion about best management practices (BMPs) for agriculture, motivated by increasing energy costs and economic pressures. Farmer interest in BMPs is associated with the increas ...
This project was initiated in 2016 to evaluate the new compound containing N, P, S, Zn compared with traditional compound DAP in cotton in Xinjiang, China.
棉花的4R钾肥管理棉花分布在全国25个省份，面积超过7500万亩，皮棉总产量达650万吨。北方棉区主要分布在新疆、河南、河北、山东，面积和产量占全国的2/3以上，使农民增收的主要经济作物之一。对棉花高产优质至关重要，但北方棉区施钾量不足。这篇文章着重阐述了棉花生产中按照正确的品种、正确的用量、正确的施肥时期和施肥方法的4R养分管理措施进行钾肥管理对棉花产量、品质和经 .

The frequency and severity of potassium (K) deficiency symptoms in cotton have increased in some soils in the US Cotton Belt over the past decade or so. Insufficient levels plant available K in these ...
A study was undertaken in the Bt cotton growing farmer fields of Raichur district with the following objectives 1. To know the effect of targeted yield approach on growth, yield and quality of Cotton ...
Soil potassium supply capacity and relation with cotton yield and fiber quality in main cotton areas in North ChinaIn order to realize soil potassium status and supply capacity as well as their relation with cotton yield and quality in the main cotton areas in North China, surface soil (0-20 cm), cotton plant and ...
Effect of Potassium Chloride Application for Rice, Cotton and Potato in the Irrigated Zone of KazakhstanBy Abdulla Saparov, Rakhimzhan Eleshev, Beibut Suleimenov, Gennadi Peskovki and Alexey Shcherbakov
The project was initiated to assess the yield responses to N, P and K fertilizer application in different Bt cotton growing farmer fields and also understand the extent of indigenous nutrient supplyin ...
Deficiência de boro: escurecimento da medula do pecíolo foliarBoro: No início do florescimento do algodoeiro em solo deficiente surgem, em manchas isoladas da lavoura, plantas com ponteiros cloróticos e folhas novas disformes e com limbos enrugados. Os botões fl ...
Deficiência de enxofre: clorose de ponteiro ("verde limão")Enxofre: As plantas deficientes apresentam crescimento prejudicado, com poucos ramos vegetativos e com clorose foliar. Diferencia-se da carência de nitrogênio por ocorrer em manchas isoladas da lavour ...
Avermelhamento internerval devido à deficiência de magnésioMagnésio: Da mesma forma que o cálcio, os distúrbios nutricionais com magnésio ocorrem com freqüência em solos ácidos. As plantas desenvolvem-se lentamentes, surgindo nas folhas do "baixeiro" uma clor ...
Detalhe do bronzeamento da fome de potássioPotássio: A conhecida "fome de potássio" inicia-se durante a frutificação das plantas, freqüentemente em manchas isoladas da lavoura. Nas folhas do "baixeiro"surge uma clorose entre as nervuras, que e ...
Algodão cultivado sem fósforo, por 8 anos em solo deficienteFósforo: Ao contrário do nitrogênio, a deficiência de fósforo atrasa o desenvolvimento do algodoeiro. As plantas crescem muito pouco e as folhas mostram-se mais escuras e menores do que as normais. Po ...
Clorose geral de algodoeiro adubado com apenas 25 Kg de N/ha, em solo continuamente cultivadoNitrogênio: Inicia-se com um amarelecimento uniforme da parte vegetativa, com destaque para as folhas mais velhas, do "baixeiro" das plantas, onde surgem pontos avermelhados e/ou pardos nos limbos. Há ...
Demonstrating a link between nutrient use and water management to improve crop yields and nutrient use efficiency in arid Northwest ChinaThis article showed the better interaction of nutrients with water management
The importance of K in crop yield and nutrient use efficiencyFarmers usually apply more P than K in crop production, most probably because of an assumed lower availability of P in soils and a lack of demonstrated K deficiencies. Attention must be paid to nutrie ...
