“…Apabila lingkungan hidup tanaman kacang tanah berada dalam keadaan baik, seperti pada jarak tanam 30 cm x 15 cm, maka unsur hara makro dan mikro dari pemberian POC akan terserap tanaman dalam jumlah yang cukup, dengan cukupnya kebutuhan hara, hal ini mengakibatkan pembentukan karbohidrat hasil fotosintesis akan tinggi. Hal ini senada dengan hasil penelitian Aslamiah and Sularno (2017), Parameshwarareddy, et al, (2019), Juliete et al, (2018), Thuiyalage et al, (2019, Nweke, et al (2013), bahwa pemberian bahan organik dengan jarak tanam yang tepat dapat meningkatkan pertumbuhan dan produksi kacang tanah. POC dapat memperbaiki karakteristik tanah marjinal sehuingga dapat meningkatkan pertumbuhan dan produksi kacang tanah.…”

Peanut production has decreased, among others, due to cultivation techniques, varieties, diseases and increasingly narrow planting areas. One of the cultivation techniques to increase crop yields is the use of liquid organic fertilizer (POC) and spacing. The research method used was Randomized Block Design, factorial pattern. Consisting of two treatment factors, namely POC concentration (0, 5, 10, and 15 ml L-1 water) and spacing (30 cm x 10 cm, 30 cm x 15 cm and 30 cm x 20 cm), repeated three times. .. The results showed that: (1) there was an interaction between POC treatment and plant spacing on the number of pithy seeds and dry seed weight per plot. Independently, liquid organic fertilizer and plant spacing had an effect on plant height, number of leaves, dry weight of stover, number of filled pods, number of empty pods, percentage of filled pods and weight of 100 seeds, and (2) At a spacing of 30 cm x 15 cm, The optimum POC concentration was 13.24 ml L-1 of water, with a maximum dry seed weight of 1.436 kg plot-1 or equivalent to 2.66 tons ha-1.

“…O uso de insumos orgânicos, dentre eles o esterco bovino incrementa as características físico-químicas do solo, devido elevar a matéria orgânica, disponibilidade de nutrientes, retenção de umidade e capacidade de troca de cátions (RODRIGUES et al, 2017;NUNES et al, 2018). Toledo et al (2017) ao avaliarem a resposta do feijoeiro submetido a aplicação de fertilizantes de natureza orgânica e mineral concluíram que o esterco proporcionou maior crescimento e produtividade.…”

As altas temperaturas e baixa pluviosidade salinizam água e solo na Região Nordeste, ocasionando redução no desenvolvimento de diversas espécies, dentre elas, o feijoeiro fava. Para tanto, objetivou-se avaliar variedades de feijão-fava submetidas a níveis de salinidade e adubação orgânica. O estudo foi conduzido em ambiente protegido, nas dependências da Universidade Federal de Campina Grande, campus Pombal. O delineamento experimental foi em blocos ao acaso, disposto em esquema fatorial 3x4x5, sendo: três variedades de feijão-fava (V1: lavandeira; V2: raio-de-sol e V3: rajada), quatro volumes de esterco bovino (A1: 0%-sem adubação; A2: 8%; A3: 16% e A4: 24%), aplicados em função do volume de solo do recipiente e cinco níveis de salinidade na água de irrigação (S 1 = 0,3 dSm-1 ; S 2 = 1,0 dSm-1 ; S 3 = 1,7 dSm-1 ; S 4 = 2,4 dSm-1 e S 5 = 3,1 dSm-1). A variedade Raio de Sol apresentou maior crescimento em relação às demais, entretanto a cultivar Rajada apresentou maior aclimatização às condições salinas, principalmente com uso do esterco bovino na concentração de 24%. O esterco bovino atenua o efeito nocivo da salinidade, entretanto doses acima de 16% de esterco em altas salinidades podem ser prejudiciais ao feijoeiro-fava. Palavras-chave: água salina; comportamento vegetativo; manejo orgânico; esterco; Phaseolus lunatus L.

Drought stress is a threat to agriculture which is decreasing the yield of crops and creating a considerable loss. This research focused on the part played by silicon dioxide nanoparticles (SiO 2 NPs), biofertilizers, and nanosilicab on Triticum aestivum under control and drought stress. Nanosilicab enhanced the germination percentage, germination index, and germination vigor index by 23.07%, 14.49% and, 93.10% under control and 14.42%, 10.52%, and 46.15% under drought. In the pot experiment, the soil was treated with 150 mg/kg SiO 2 NPs, 1% biofertilizer and, 1% nanosilicab before sowing. Nanosilicab increased shoot length and root length by 9.39%, 10.76%, 22.41%, 18.76%, 30.58%, and, 21.56% under control and drought stress conditions. It also increased photosynthetic pigments, osmolytes content, relative water content, membrane stability index, phenol, and avonoid content. The increase in antioxidant activity was signi cantly high by the application of nanosilicab i.e. the augmentation in catalase, peroxidase, and superoxide dismutase was 68.65%, 83.69% and, 85.99% respectively. It also increased the indole acetic acid and cytokinin to 22.28% and 14.79% in comparison to control. The improvement in hundred grain weight and grains per spike by the use of nanosilicab was 36.25%, 38.76%, 27.47%, and 22.59% as compared to control. The positive interaction of nanosilicab with the roots of plants in the rhizosphere improved the growth of plants signi cantly and a potential candidate for application on crops. The novelty of this study lies in the formulation of nanosilicab and its role in drought amelioration.
