Leaf gas exchange, physiological growth, yield and biochemical properties of groundnut as influenced by boron in soilless culture

Abstract

Crops specific proper concentration of micronutrient application is necessary to improve the yield and quality of crops. Therefore, an experiment was conducted to identify the optimum dose of boron for groundnut plant. Six level of boron (B) application, B 0 (0 ppm), B 1 (0.5 ppm), B 2 (1 ppm), B 3 (2 ppm), B 4 (4 ppm) and B 5 (8 ppm) were evaluated. Photosynthetic rate, transpiration and stomatal conductance were increased for boron application but leaf vapor pressure deficit decreased. Physiological growth parameters, yield and yield contributing character, and shelling percentage was highest for B 3. The values of biochemical traits including protein, oil and vitamin E content were higher for B 4. Thus, leaf gas exchange showed that boron can be used to culture groundnut as it provides high yield and biochemical properties.

Effect of Nutrient Solution on Growth and Yield of Cherry Tomato Varieties in Soilless Culture

“…This might be due to that full strength of Rhaman and Inden contained all plant nutrient elements in proper proportion which helped the plants developing a larger size and shape of fruits. The plants required optimum nutrient combination for proper growth and better yield stated by Quamruzzaman et al (2017). The results of the present study were consisted with the findings of Nandapuri et al (1973) and Ahmed et al (1988).…”

Photosynthetic Response and Antioxidant Content of Hydroponic Bitter Gourd as Influenced by Organic Substrates and Nutrient Solution

“…On the other hand, full strength of Rahman and Inden (2012) solution (N 1 treatment) provided optimum and proper nutrient combination for high-value crops. Quamruzzaman et al (2017) suggested that maximum stomatal pores in the epidermal layers of leaves were opened because of proper supply of nutrient solution. The result suggesting that the increased E was associated with the increased P N and g s agreed with the finding of Lu et al (2014).…”

“…The yield contributing char-acters performed better in N 1 nutrient solution. This might be due to an adequate supply of nutrient combination provided by treatment N 1 , resulting in the maximum reproductive growth (Quamruzzaman et al, 2017) because the plants required optimum nutrient combination for proper growth and better yield. When all the plant nutrients with the growth promoters and the regulators were supplied, the metabolic function of the plants would progress in the right direction and rate, whereas the yield and yield contributing characters increased gradually .…”

“…It might be due to the appropriate supply of nutrient solution of N 1 that contained the required nutrient elements to produce the higher biochemical components. Quamruzzaman et al (2017Quamruzzaman et al ( , 2018 and reported that adequate supply of nutrient helped get higher mineral elements.…”

“…The leaf chlorophyll content was measured by following Dey et al (2016) procedure. The P N , E, and g s were measured using the LC-pro portable photosynthetic system (ADC BioScientific Ltd., UK) as described by Quamruzzaman et al (2017). Ascorbic acid was determined by titrating a known weight of sample with 2,6dichlorophenol-indophenol dye using metaphosphoric acid as a stabilizing agent (Albrecht, 1993).…”
