“…Significantly less number of bolls m -2 was obtained with 55,555 plants ha -1 (60 cm x 30 cm) treatment. The results are in conformity with results of Dong et al, (2010), where high plant density increased the number of bolls per unit area relative to low plant densities. .…”

“…As a consequence, potash consumption has increased dramatically in most regions of the world [10]. A strong positive relationship between K fertilizer input and grain yield was shown by Dong et al [11]. Potassium deficiency can occur under salt stress because the high concentrations of Na inhibit K activity in the soil solution, result in a decrease of K availability.…”

A greenhouse study was conducted to explore the effect of various rates of potassium sulfate (K 2 SO 4 ) nanoparticles on alfalfa (Medicago sativa L.) growth and physiological response under salt stress. One salt-tolerant genotype (Mesa-Sirsa) and one salt-sensitive genotype (Bulldog 505) were selected based on germination under salt and were planted in pots containing 2 kg of sand. The two genotypes were subjected to 0 and 6 dS•m −1 salt levels using CaCl 2 •2H 2 O: NaCl (2:1) mixed with Hoagland solution. Three K 2 SO 4 nanoparticle treatments consisting of, 1/4, 1/8, and 1/10 of the potassium (K) level in full strength Hoagland solution (235 mg•L −1 ) were applied. Adding K 2 SO 4 nanoparticles at the 1/8 level resulted in the highest shoot dry weight, relative yield, root length and root dry weight in both genotypes. The different rates of K 2 SO 4 nanoparticles affected significantly Na/K ratio and the concentrations of Calcium (Ca), Phosphorus (P), Copper (Cu), Manganese (Mn), and Zinc (Zn) in plant tissue. The application of K 2 SO 4 nanoparticles at the 1/8 rate enhanced the plant's physiological response to salt stress by reducing electrolyte leakage, increasing catalase and proline content, and increasing antioxidant enzymes, activity. These results suggest that the application of K nanoparticles may have better efficiency than conventional K fertilizers in providing adequate plant nutrition and overcoming the negative effects of salt stress in alfalfa.

“…Application of 240:150 kg NK ha -1 with plant density of 7.5 plants m -2 recorded significantly higher seed cotton yield (1545 and 2158 kg ha -1 , respectively) at low and high fertility fields (Dong et al, 2010). While, Kaur et al, (2010) At Dharwad under rainfed condition Gundlur et al, (2013) revealed that growth, yield parameters and yield (2303 kg ha -1 ) were significantly improved particularly with 175 % RDF compared to RDF (1986 kg ha -1 ).…”
