Influence of integrated nutrient management on growth, yield parameters and yield in French bean (Phaseolus vulgaris L.)

Abstract

An investigation was carried out during rabi season of 2013-14 at vegetable farm, College of Horticulture, Mandsaur (Gwalior) to study the effect of integrated nutrient management on growth, yield parameters and yield in French bean. The treatments comprised six nutrient levels N 1 , N 2 , N 3 , N 4 , N 5 and N 6 and three varieties viz., Arka Komal (V 1 ), Contender (V 2 ) and Swarna Priya (V 3 ). It was noticed that application of nutrient levels and varieties had significant influence on growth, yield and yield parameters. Nutrient level N 4 [Vermicompost (10t/ha) + N (50kg/ha) + Rhizobium (15g/kg seed) + PSB (15g/kg seed) + P 2 O 5 (80kg/ha) + K 2 O (80kg/ha)] recorded the maximum plant height (57.92cm), fresh weight of shoot (43.70g), dry weight of shoot (11.33g), number of pod per plant (31.81), pod length (15.55cm), shelling percent (76.87%), harvest index (26.82%), seed yield per plant (17.35g) and seed yield per hectare (25.22q). The maximum days for 50 per cent flowering were taken with the application of N 6 nutrient level which was significantly higher over other nutrient levels. Among the varieties Swarna Priya (V 3 ) recorded the highest growth, yield parameters and yield in French bean. Earliest 50% flowering was recorded in variety Contender followed by Arka Komal.

Influence of Nitrogen Levels and Microbial Inoculants on Yield and Economics of French Bean (Phaseolus vulgaris L.)

“…A significant increase in the number of seeds/pods probably may be due to balanced nutrition and proper vegetative growth which later converted into reproductive phase and resulted might in a greater number of seeds. The results were similar to [13].…”

“…Rhizobium and phosphate solubilizing bacteria (PSB) assume countless importance on account of their dynamic role in N 2 -fixation and P solubilizations. Rhizobium and PSB use have been beneficial for increasing French bean productivity" [13].…”

Effect of Conjoint Application of Inorganic and Organic Nutrient Sources on Yield and Economics of French Bean (Phaseolus vulgaris L.)

“…The increased growth with substitution of N by organic manures might be due to the fact that organic manures release nutrients slowly (Sharma et al, 2015), resulting in enhanced nutrient use efficiency (Verma et al, 2015;Mohanty et al, 2017) and availability of micro nutrients (Nawalgatti et al, 2009;Shubhashree et al, 2011). Higher yield of treatment comprising of inorganic fertilizers in combination with organic manures may be due to the increased availability and uptake of macro and micro nutrients by the plant, resulting in higher rate of physiological (Barcchiya and Kushwah, 2017) and anabolic processes (Sen et al, 2006;Ramana et al, 2010). Sharma et al, 2018 reported increased uptake of N, P and K by French bean significantly through the combined application of vermicompost and N over the use of farmyard manure and nitrogen application.…”

Residual Effect of Nutrient Management Practices in Lowland Rice Varieties on Growth, Productivity, Economics and Nutrient Uptake of Succeeding Black Gram in Rice–Black Gram Cropping Sequence

“…inorganic source and control. Higher yield in treatment comprising inorganic fertilizers in combination with organic manures might be due to the increased availability and uptake of macro and micro nutrients by the plant, resulting in higher rate of physiological (Barcchiya and Kushwah, 2017) and anabolic processes (Ramana et al, 2010).…”
