IntroductionPhosphorus (P) and potassium (K) deficiencies are increasingly being reported in Ghana’s interior savanna soils. Smallholder farmers consider soybeans as a “zero-input” crop resulting in low yields and profitability. Studies indicate a positive response to P application; however, knowledge of the synergistic effect of P and K in soybeans is limited. A six-site year experiment was conducted to evaluate the synergy of P and K for soybean yield, partial factor productivity (PFP), agronomic efficiency (AE), rain-use efficiency (RUE), and variable-cost ratio (VCR).Materials and methodsThe treatments were 4 × 4 factorial combinations of P at 0, 25, 50, and 100 P2O5 (kg ha−1) and K at 0, 25, 50, and 100 K2O (kg ha−1), and their combinations laid out in a randomized complete block design with four replications. The soybean cultivar “Favor” (TGx 1844–22E), released and registered by the Savanna Agricultural Research Institute (SARI), was used as the test crop.Results and discussionFlowering time was reduced at Nyankpala and Dokpong by 0.2 and 0.4 (days), while plant height was increased by 4%–18% over control. Yield and RUE increased as P and K rates increased, with the greatest yield from T15 (P100K50) in Manga (2.34 t ha−1) and Nyankpala (2.37 t ha−1), T16 (P100K100) at Dokpong (2.68 t ha−1), and RUE from T15 across locations. The PFP, AE, and VCR values decreased with increasing P and K rates, with the greatest PFP, AE, and VCR from T5 (P25K0) at Manga and Dokpong and T2 (P0K25) at Nyankpala. All treatments exceeded the VCR > 2.0 threshold, except T12 (P50K100) across locations, and T16 at Manga and Nyankpala. The greatest economic returns are T5 at Manga and Dokpong and T2 at Nyankpala.ConclusionBy all indications, the study justified the use of nutrient input in soybeans of P and K to enhance grain yield and profitability. Avoiding broadcast applications and adopting precision placement using the 4R nutrient principles of right placement, right fertilizer source, right rate, and the right time is key. The study recommends further experiments on different combinations of P and K in a long-term residual study.

Education plays an important role within the development of people thereby influencing the growth of the state. Education is one among the necessary sectors within the economy that had brought revolutionary changes within the recent times. Republic of India that was once thought-about as majorly associate in nursing agricultural economy is currently developing in numerous sectors at a quicker rate. However, the evolution data of knowledge and technology has created a divide between the urban and therefore the rural Republic of India despite of globalization. It's thanks to the digitalization in numerous sectors that has taken place across globe. Villages in Republic of India form the backbone of our nation contributory to socio- economic and human resource development of the state. As per 2011 census, nearly sixty eight of the Indian population belongs to geographic area. Though the life within the rural areas is currently connected to cell phones, smartphones, digital TV transmission, however to an oversized extent they're stop from the most stream of urban areas thanks to lack of infrastructure support, poor property, language barriers particularly within the education sector. Digital technology makes life easier for each educators and students. So as to rework into a Digital India, it's to develop the facilities of rural little villages beside sensible cities in Republic of India. Results and Conclusions: This paper tries to debate regarding the digital tools to be developed in rural areas in a reasonable manner and therefore the core elements of Digital technology likewise because the future scope and challenges of a rural society in moving towards Digital education.
