Abstract

Two field experiments were carried out in two successive seasons of 2013 and 2014 at the Agricultural Experimental Station of the National Research Centre, EL-Nubaria, Elbehira Governorate, Egypt, to study the effect of three levels of Glutamine (25ppm, 50ppm and 100ppm) spraying in addition the control on growth, yield and pods quality of two bean cultivars (Paulesta and Oxzira). Results showed that using Oxzira cv. gave the highest values of the vegetative growth (number of leaves and number of branches as well as fresh and dry weight of whole plant), total yield, quality and Chemical constituents (Total Free amino acids in leaves and total phenolic acids in pod). Whereas, Paulesta cv. Resulted the highest values of plant length and Total Free amino acids in pods. Spraying bean plants by Glutamine (25ppm, 50 ppm) increased vegetative growth, total yield and quality with no significant difference between 50 and 25 ppm. Whereas, using Glutamine as (25ppm) increased Total Free amino acids in leaves and total phenolic acids in pod but Total Free amino acids in pods highest when using Glutamine (100ppm).

1. Introduction

Snap Bean, Phaseolus vulgaris L. which commonly known in Egypt as Phasolia is a member of family Fabaceae. It is also known as Common, Snap, Kidney, French or Haricot beans (Bisby et al., 2011). It is one of the most important food crops in Egypt and consumed as a cooked vegetable either as dry seeds or green pods. It plays an important role in human nutrition as a cheap source for protein, carbohydrates, vitamins and minerals.

Many investigators reported that the vegetative growth, total and exportable yield as well as pod quality of snap bean ( Phaseolus vulgaris, L ) are greatly affected by genotype of the variety Nassar (1986), Abou El Hassan et al., ( 1993), Mohamed (1997) , Amer et al., ( 2002),, Abdul Mawgoud et al., ( 2005).

Nitrogen is required by plants in comparatively larger amounts than other elements (Marschner., 1995).

In recent years, the world focused his attention to minimize environmental pollution and human health impacts, by reducing the use of synthetic fertilizers and chemicals in crops production. Especially, vegetables which eat fresh using natural alternatives, (IFAOM/SOEL, 2000 and FAO/TTC, 2001).

Amino acids is a well known biostimulant which has positive effects on plant growth, yield and significantly mitigates the injuries caused by abiotic stresses (Kowalczyk and Zielony 2008). Saeed et al., ( 2005) on soybean found that treatments of amino acids significantly improved growth parameters of shoots and fresh weight as well as pod yield. El- Zohiri and Asfour (2009) on potato found that spraying of amino acids at 0.25 ml/L significantly increased vegetative growth expressed as plant height and dry weight of plant.

The requirement of nitrogen of amino acids in essential quantities is well known as a mean to increase growth and yield for all crops. Furthermore, nitrogen and/or amino acids are the fundamental ingredients for the process of protein synthesis. The important of nitrogen or amino acids came from their widely use for the biosynthesis of large variety of non protein nitrogenous materials i.e., pigments, vitamins, coenzymes, Purine and pyrimidine bases (Kamar and Omar, 1987).

Many studies reported that, the foliar application of amino acids caused an enhancement in plant growth, fruits yield and its components  (Kamarand Omar, 1987) on sweet pepper. Karuppaiah et al., 2000 on potato, El-Shabasi et al., 2005 on cucumber and Awad et al., 2007 on garlic

The possibilities of using amino acid in modern agriculture have been studied by many researchers (Fawzy et al., 2010; Abdel-Mawgood et al., 2011; El Awadi et al., 2011; Razieh et al., 2012).

The aim of the present study is to investigate the effects of Foliar Spray of Glutamine on growth, yield and quality of two snap bean varieties

A field experiment was carried out at the experimental station of National Research Centre, at EL-Nubaria, EL-Behira Governorate, Northern Egypt, during two successive summer seasons of 2013 and 2014 to study the differences between two bean cultivars (Paulesta and Oxzira) and three levels of Glutamine (25ppm, 50ppm and 100ppm) spraying in addition the control on growth, yield and pods quality of snap bean (Phaseolus vulgaris L.). Seeds of bean were sown on the last week of April in 2013 and 2014, respectively. Seeds were sown on two sides of ridge; ridge was 80 cm width and 4 m length and 10 cm apart. Each plot included 4 ridges and the plot area was 12.8 m2. Glutamine foliar application sprayed 30 and 40 days after sowing.

The soil of the experimental field was sandy soil and the physical and chemical analyses were presented in Table (1). The normal agricultural practices required for bean production were applied as commonly followed in the farm.

2.1. Data Recorded

Vegetative growth: A random sample of 5 plants from each plot was taken at 45 days after sowing and the following vegetative characters were recorded: plant length, number of leaves and number of branches as well as fresh and dry weight of whole plant.

Pods yield: At harvest stage the mature pods of bean for each experimental plot were collected along the harvesting season and the total pods yield was recorded as ton/fed.

2.2. Pods Quality

Random sample of 50 pods from each plot was taken and the physical properties (average pod weight and pod length) were recorded.

2.3. Chemical Constituents

Protein percentage was determined according to A.O.A.C. (1990). Total Free amino acids were determined using the ninhydrin colorimetric method defined by Plummer (1978). Following the method reported by Snell and Snell (1952), total phenolic compounds were estimated.

The treatments were arranged in a split plot design with four replicates where, bean cultivars were arranged in main plots, while Glutamine foliar application treatments were in addition the control distributed in the sub plots. The obtained data were statistically analyzed according to the method described by Gomez and Gomez (1984).

3. Results and Discussion

3.1. Vegetative Growth Parameters

3.1.1. Effect of Snap Bean Varieties

Data in Table (2) show that, snap bean varieties in both seasons have a significant effect in their vegetative growth parameters except for fresh and dry weight of leaves in the two seasons of study. Meanwhile, the highest value of plant length was recorded by Paulista cv. However, Oxzira cv.  gave the highest values of other vegetative growth parameters ( number of leaves and branches as well as fresh and dry weights of leaves of snap bean). These results held true in the two seasons of the study. On the contrary, the lowest amount of plant height was found by Oxzira cv. and the lowest amount of all other vegetative parameters were found by Paulista cv.   The observed differences in vegetative growth of cultivars are mainly due to the genotype of each cultivar. This result was in harmony with previous findings (Abou El –Hassan et al 1993, Mouhamed. F.M., 1998, and Abdul – Mawgoud et al 2005) on snap bean plants.

3.1.2. Effect of Foliar Application of Glutamine

Data of the measured vegetative growth parameters of snap bean plants in relation to the applied Glutamine are presented in Table (2). Generally, application of Glutamine had a significant effect in the vegetative growth parameters (number of leaves and fresh and dry weight of leaves) in both seasons of study. Meanwhile, the highest values plant height parameter was obtained from the application of Glutamine at a rate of 100 ppm in both seasons as compared with those obtained from the control and other treatments. Moreover, the lowest of plant length was found by control plant (foliar spray of water). Furthermore, the highest amount of number of leaves and branches as well as fresh and dry weights of leaves of snap bean were found by application of Glutamine as a rates of 25 ppm. On the other hand, the lowest values of vegetative growth parameters were found by foliar application of Glutamine at rates of 100 ppm. These findings were true in the two seasons. These results are in agreement with those obtained by many investigators Kowalczyk and Zielony 2008.

4. Conclusion

It could be recommended that all spraying bean plants by Glutamine (25ppm and 50 ppm) increased vegetative growth, total yield and quality. Whereas, using Glutamine as (25ppm) increased Total Free amino acids in leaves and total phenolic acids in pod but Total Free amino acids in pods highest when using Glutamine (100ppm).
