RESUMO
A field study was conducted in the 2019 kharif season at the Agronomy Instructional Farm, SDAU, SKNagar, Gujarat, India. To investigate that the sowing time and spacing influenced yield, quality and economics of Bt cotton (Gossypium hirsutum L.) in loamy sand soil. Twelve treatment combinations were examined, involving three sowing times (T1: 3rd week of May, T2: 1st week of June, T3: 3rd week of June) and four plant spacings (S1: 90 cm × 60 cm, S2: 90 cm × 45 cm, S3: 60 cm × 60 cm, S4: 60 cm × 45 cm). Four replications of a split plot design were used for the experiment. The third week of May was consistently the best time to sow cotton, according to the results, producing the maximum yields of seed cotton and stalk cotton. The quantity of monopodial branches/plant, harvest index and plant population as well as quality parameters such as oil content and ginning percentage were not significantly impacted by sowing time. The 3rd week of May sowing also yielded the highest benefit cost ratio and net realization. In terms of plant spacing, the spacing of 60 cm × 45 cm promoted highest plant population, taller plants and increased yield attributes like the bolls/plant, boll weight and seed cotton yield/plant. The highest seed cotton yield and stalk yield were achieved with this spacing. Harvest index and quality parameters were unaffected by plant spacing. The narrow spacing of 60 cm × 45 cm also resulted in the highest benefit cost ratio and net realization. The interaction effect between sowing time and plant spacing did not significantly influence growth, yield, yield attributes and quality parameters of Bt cotton.
RESUMO
A field experiment was conducted at the Agronomy Instructional Farm, C. P. College of Agriculture, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar to investigate the “effect of foliar nutrition on yield, quality, nutrient content and uptake of kharif cowpea” during kharif season of 2020. In Randomize Block Design, eight treatment combinations were tested in four replications. Cowpea variety Gujarat cowpea 5 was planted at a distance of 45 cm × 10 cm. Application of 75% of RDF + 2% spray of each urea and urea phosphate at 15 and 30 DAS gave significantly higher yield (1422 kg/ha), protein content (22.93 %), nutrient content of nitrogen and phosphorus in seed (3.67 % and 0.446 %) and in stover (0.73% and 0.273% respectively) and nutrients uptake of nitrogen (71 kg/ha), phosphorus (13 kg/ha) and potassium (56 kg/ha) by cowpea crop it was at par with application of 75% of RDF + 2% spray of NPK 19:19:19 at 15 and 30 DAS
RESUMO
HIV management is currently in an era of effective, potent antiretroviral therapy. Modern drug discovery and development have transformed HIV-1 disease into a treatable, chronic infectious disease. Complete suppression of viral replication is critical for long-term durability of antiretroviral therapy. Partial suppression, even at very low levels, is likely to lead to virologic failure and ultimately to the appearance of drug resistance. The relationship between adherence and resistance to HIV antiretroviral therapy is more complex than to state 'non-adherence increases the risk of drug resistance.' In many patients who fail to respond to initial therapy, the primary reason for failure is their inability to take the prescribed drug regimen or nonadherence.
