Abstract

Use of organic manures for crop productivity not only improve crop production but also improving soil physicochemical properties. It also reduces soil and water pollution by acting as chelating agent for inorganic nutrients. Keeping these things in view an experiment was carried out aiming the use of different organic manures for improving crop productivity and to select a potential organic manure that improve crop productivity compared to others. All the manures were applied at the same rate 5 tons ha-1. The results revealed that all the wheat parameters were significantly affected by differences in nature of organic manures except days to emergence. Plots receiving Poultry manures has high Spikes m-2 (274), Grains spike-1 (60), more 1000 grain weight (42.287 g), high biological yield (11435 kg ha-1) and high grain yield (3996 kg ha-1). Similarly, Sheep manure had also great effect on wheat parameters such as higher emergence m-2(103), Tillers m-2 (308), plant height (104.50 cm), Grains spike-1 (60) and similar 1000 grain weight compared to poultry manures (42.200). Cattle and Farmyard manure were also found better compared to legume residue but were found less important in improving wheat quality compared to poultry and sheep manure. Similarly, legume residues showed very poor performance in improving wheat quality compared to other organic manures. Wheat parameters were found better performed when poultry or sheep manures applied at the rate of 5 tons ha-1. Therefore, it is recommended that application of sheep or poultry manures at the rate mentioned above improve wheat components under the agro-climatic conditions of Pakistan.

Introduction

Wheat is an annual cereal crop and is the used as a staple food by human beings and is used for livestock feeding in all over the world. Pakistan economy is widely boost up due to the cultivation of wheat. It contributes about 3% to the total GDP of Pakistan [1]. The average production of wheat in Pakistan is much lower compared to Mexico and China. This lower production in Pakistan is due to imbalance application of fertilizers and given of lower preference to organic fertilizers [2]. Imbalance inorganic fertilizers application and no use of organic fertilizers can loosen the soil and causes increase erosion and loss of fertile soil. Therefore organic fertilizers and inorganic fertilizers proper application can improve the soil properties and increases soil fertility. Organic fertilizers/manures are the chief sources of NPK and other essential plant nutrients [3]. The most important organic sources containing N is poultry manure, farmyard manure and crop residues. Inorganic fertilizers losses from the field are more and act as the most important source of causing atmospheric pollution. Therefore, reuse of organic materials of farm can not only improve crop yield but also decreases pollution [4]. Importance of organic fertilizers cannot be ignored as they are used as substitutes of inorganic fertilizers because they improve both the physical and chemical properties of soil [5].

In all the organic fertilizers poultry manure can enhance wheat yield and quality compared to others because of containing high amount of nutrients [6]. Most of the researches of organic fertilizers showed that poultry manure improve wheat yield more efficiently like as Izunobi [7] conducted an experiment, reported that the richest source of most of the absorbable plant nutrients are contained by poultry manure. Improving yield of crops by poultry manure is because it mineralizes faster and contain high amount of basic nutrients compared to other organic fertilizers [8]. Poultry manure contains high amount of basic nutrients and therefore increases leaf area, grain yield, dry matter and chlorophyll content of plant [9]. For increases most of the crop production in different parts of the world, different organic sources such as cattle manures, poultry manures, pig manures and residues compost are recommended [10]. Residual effect of organic manures is long because the release of nutrients from organic manures are so slow due to time taken on decomposition [3].

Methodology

This research was conducted in the University of Agriculture, Peshawar at New Developmental Farm (NDF) to explore different organic manures effect on wheat yield and quality during the month of early December 2016. This experiment was carried out in randomized complete block design (RCBD) with three replications. Five treatments were used as factor. Pirsabak-2013 varieties were used as a check crop.

T1=Farmyard manure @ 5 tons ha-1, T2=Poultry manure @ 5 tons ha-1, T3=Legume residues @ 5 tons ha-1, T4=Sheep manure @ 5 tons ha-1, T5=Cattle manure @ 5 tons ha-1. No inorganic fertilizers were applied, as all the organic manures were applied at the rate of 5 tons ha-1. Effect of organic manures on the following parameters were found.

Days to emergence

Emergence data were taken by calculating days to emergence from the planting date upto 80% of seedlings appear in each plot (Figure 1).

Results and Discussion

Nowadays, farmers are facing lots of problems by using chemical fertilizers in terms of short term residual effect, high cost, and the disturbance in structures of soil that can cause to erosion and lead to not only affect the soil properties adversely but can also hinders the target crop yield [3]. Most of the underprivileged farmers uses both organic and inorganic manures alone and in mixed combination without knowing that which organic manure can gives us best results when used alone. Taking all of these things in view a research aiming to improve agriculture was carried out that can lead to a step towards sustainable agriculture due to its long term residual effect. Data in Tables 1 and 2 shows the effect of organic manures on the wheat yield parameters. The tables showed that organic manures effect on days to emergence is not significantly different from each other but legumes residues incorporation delayed emergence compared to others. Using organic manures improve porosity that ultimately enhance water use efficiency and thus increases biomass production [1]. It is also been reported [11] that fresh weight of wheat is enhances by application of organic manures to soil. Emergence m-2 was high by applying poultry and sheep manure and FYM and CM were not significantly different from each other.

Figure 7: Biological yield.

Biological yield=(Biological yield (kg))/(R-Length × No.of Rows × R-R distance)

LR showed poor effect on seed emergence m2 and were significantly different from all others. Tillers m-2 had showed greater response to sheep manure which is not significantly different then poultry manure followed by cattle manure and farmyard, legume residues had showed lowest response so tiller m-2. Organic manures improve nutrients uptake by providing ideal conditions for both microbial activity and to uptaking nutrients from soil [12,13] manures provide ample nutrients to plants that can improve growth parameters of wheat crops [14]. Plant height shows greater response to sheep manure which is significantly different from all others. While low response of plant height were obtained by legume residue incorporation. Higher spikes m-2 were obtained by application of poultry manure which was significantly differ from other organic manures. While poor spikes m were obtained by application of legume residue to the field.

Grain yield (kg ha-1)

Each plot seeds are weighed separately and are converted into (kg ha-1) (Figure 8).

Figure 8: Grain yield.

Grain yield=(Grain yield (kg))/(R-R Distance × No.of rows × RLength)

Higher grains per spike were obtained by application of poultry and sheep manures while lowest grains per spike were obtained by legume residues incorporation. Application of poultry manure also increases thousand grain weight while the lowest weight were obtained from plots with legume residue incorporation. Increased biological yield were obtained from poultry manure which was significantly different from others. While the lowest were obtained from legume residues. Poultry manure also increases grain yield while the lowest grain yield were obtained from farmyard manure. Mashori et al. [2], Memon et al. [15], Moe et al. [16] reported that soil properties and maize growth can be improved by the application of organic manures into the soil. So, Soil applied (ammended) with poultry or sheep manures can gives very precise results. It is recommended to use poultry and sheep manure for obtaining high yield.
