Growth and Yield Response of Bush Bean (Phaseolus vulgaris L.) as Influenced by Different Levels of Nitrogen and Phosphorus Application

Abstract

The experiment was conducted at Horticulture Farm at Sher-e-Bangla Agricultural University, Bangladesh during the period December, 2014 to March 2015 to evaluate the effect of different levels of nitrogen and phosphorous on the growth and yield of bush bean. The two factor experiment was laid out in Randomized Complete Block Design with three replications. The treatment was comprised of two factors-Factor A: levels of nitrogen i) 0 kg/ha, ii) 20 kg/ha, iii) 40 kg/ha and Factor B: levels of phosphorous (P 2 O 5 ) -i) 0 kg/ha, ii) 50 kg/ha, iii) 75 kg/ha, iv) 100 kg/ha. The results revealed that most of the growth and yield contributing parameters were significantly influenced by the different levels of nitrogen and phosphorous application. The maximum promotive effect on growth and yield of bush bean was associated with 40 kg N/ha and Nasrin et al.; AJRCS, 4(2): 1-8, 2019; Article no.AJRCS.50148 2 75 kg P 2 O 5 /ha. Again their combined application enhanced maximum vegetative growth and with higher pod yield and seed yield. Therefore, application of 40 kg N/ha with 75 kg P 2 O 5 /ha can be conductive for bush bean cultivation in Bangladesh with higher yield. Original Research Article

Response of BARI Bush Bean-2 at Different Levels of Nitrogen Fertilization

“…The highest length of the green pod was found (11.15 cm) in treatment N 80 which is statistically identical with N 40 , N 120 treatments and the lowest (10.30 cm) was found in the plot treated with N 0 treatment ( Table 1). This result is in full agreement with several authors [22,23]. They reported that pod length was significantly influenced by optimum dose of N. Nitrogen is a part of the chlorophyll molecule which activates the normal metabolic process of leaves.…”

“…The lowest on pod yield plot -1 (1454.17 g) was found in control treatment (Table 1). Similar result was found by several authors [22,27]. On the other hand Gomez and Gomez [21] found significantly influenced by optimum dose of nitrogen on green…”

“…The lowest (3.55 tons) was found in the control treated plot (Table 1). Nasrin et al [22] Found the similar result and stated that pod yield of bush bean increase with the increment of nitrogenous fertilizer. Among all the essential nutrients applied to the plants nitrogen is the major one which has a key role in the process of photosynthesis.…”

Effect of Different Levels of Potassium Fertilizer on the Yield Components of BARI Bush Bean-2

“…The center of origin of this crop is South America but consumed in all parts of the globe for its edible seeds and pods [2]. Being a major grain legume crop of the world it is a resourceful short-duration legume crop with high grain yielding potential and diversified use [3]. It can be used both as pulses and vegetables.…”

“…It is also known as the french bean, kidney bean, common bean, basic bean, snap bean, raj bean, navy bean, haricot bean, string bean, pole bean, wax bean and bonchi [5]. The marketable parts of this fruit are immature green pods and marketed either in fresh or in frozen or canned condition [3]. The dry seeds also may be used as pulses for human consumption or animal feed.…”
