Evaluation of the combined use of organic and inorganic fertilizers on bulb onion (Allium cepa L.) yields in West Ugenya Sub-County, Kenya

Low yields due to declining soil fertility continue to be a major constraint to onion production in Kenya, necessitating imports to meet market demand. A field experiment was carried out for two seasons in West Ugenya Sub-County during the 2015 and 2016 short and long rains seasons, respectively to evaluate the effect of combining organic and inorganic fertilizers on the soil nutrient status, growing period and yield of bulb onion (Allium cepa L.). The experiment was a Randomized Complete Block Design (RCBD). Treatments, each replicated three times were: T1 (5Mega grams ha-1 cattle manure), T2 (46kg P ha-1 x 26kg N ha-1 inorganic fertilizers), T3 (unfertilized control), and T4 (half T1 x half T2) were evaluated. Data from T1 and T4 at the end of the two growing seasons showed significantly (P≤0.05) higher mean yields compared to the control with highest bulb yield (25.2Mg ha-1) recorded in T4. Also, significantly (P≤0.05) higher soil available P and total organic carbon was recorded in T4 at the end of season II compared to the other treatments in the same season. Seasonal variation in rainfall amount led to considerably lower yields in the short rains (season II), compared to long rains (season I). Observed data concluded that onion yields could be significantly increased by combining organic and inorganic fertilizers at the rates of 2.5Mgha1 cattle manure containing 2% N, 0.6% P and 2.3% K, with 23kg P ha-1 x 13kg N ha1 inorganic fertilizers.

Evaluation of the combined use of organic and inorganic fertilizers on bulb onion (Allium cepa L.) yields in West Ugenya Sub-County, Kenya

Abstract

Low yields due to declining soil fertility continue to be a major constraint to onion production in Kenya, necessitating imports to meet market demand. A field experiment was carried out for two seasons in West Ugenya Sub-County during the 2015 and 2016 short and long rains seasons, respectively to evaluate the effect of combining organic and inorganic fertilizers on the soil nutrient status, growing period and yield of bulb onion (Allium cepa L.). The experiment was a Randomized Complete Block Design (RCBD). Treatments, each replicated three times were: T1 (5Mega grams ha-1 cattle manure), T2 (46kg P ha-1 x 26kg N ha-1 inorganic fertilizers), T3 (unfertilized control), and T4 (half T1 x half T2) were evaluated. Data from T1 and T4 at the end of the two growing seasons showed significantly (P≤0.05) higher mean yields compared to the control with highest bulb yield (25.2Mg ha-1) recorded in T4. Also, significantly (P≤0.05) higher soil available P and total organic carbon was recorded in T4 at the end of season II compared to the other treatments in the same season. Seasonal variation in rainfall amount led to considerably lower yields in the short rains (season II), compared to long rains (season I). Observed data concluded that onion yields could be significantly increased by combining organic and inorganic fertilizers at the rates of 2.5Mgha1 cattle manure containing 2% N, 0.6% P and 2.3% K, with 23kg P ha-1 x 13kg N ha1 inorganic fertilizers.

Introduction

The bulb onion (Allium cepa L.) is adapted to growing in different agro-ecological zones (Nguthi et al., 1994) and prefer medium textured soils with a pH range of 6-7 (Muendo and Tschirley, 2004), optimal germination soil temperature of 15 - 25°C (Jaetzold et al., 2009), and can be established either by direct seeding or seedling transplanting (Muvea et al., 2014). Although onion has been grown in Kenya over a long time, production per land area is still low at a national average of 15Mgha-1 compared to Korea (67Mgha-1), Spain (54 Mgha-1), Egypt (36Mgha-1), Ghana (17Mgha-1) and Ethiopia (10Mgha-1) (FAOSTAT, 2012). In most parts of Kenya just like in the study area of West Ugenya sub-county, onion is mainly grown at small scale level, and soil fertility decline through nutrient mining and degradation is the main challenge to increased yields (Mango, 1999; Jaetzold et al., 2009; Okalebo et al., 2005), alongside post harvest losses (AFFA, 2016; USAID, 2012), and pests and disease (Muvea et al., 2014).

Combined use of organic and inorganic fertilizers has been proposed as a solution to reverse poor soil health and low crop yields (Vanlauwe et al., 2002; Sanginga and Woomer, 2009; Vanlauwe et al., 2015; Ruganzu et al., 2015). For instance onion yields resulting from combined use of organic and inorganic fertilizers in a field experiment in India were significantly (P ≤ 0.05) increased by 77% compared to no fertilizer input, and up to 45% higher yields than sole inorganic fertilizers application (Rai et al., 2016). This study was thus premised on the need to increase onion production in Kenya to meet growing demand through integrated soil fertility management and raise income to the local farmers.

This study explored the synergistic effects of Arbuscular Mycorrhizal Fungi (AMF) and nutrient fertilizer resources (organic fertilizer (cattle manure) and inorganic fertilizer (NPK) on maize plant growth and grain yield in central-northern Tanzania, emphasizing their potential in nutrient-limited environments. The AMF on the Tanzania maize variety (TMV1) in two experiments. The first experiment was conducted in a screen house to identify the most effective AMF formulation, using 81 pots with two seeds sown per pot and three AMF treatments, with cattle manure applied at the rate of 0.04375 kg per pot and 0.5 kg per hole in open field. The second experiment occurred in the field setting in a randomized complete block design with AMF, NPK, and cattle manure combinations as treatments. Each treatment plot measured 3 × 3 m, with appropriate spacing and weekly irrigation maintained throughout the season. Data on plant height, stem girth, and leaf length were collected during the second and third months to assess treatment impacts. Over four weeks, treatments that combined AMF with cattle manure significantly enhanced key maize growth parameters, including plant height, stem girth, and leaf length. Treatment T5 (mycorrhiza 2 with cattle manure) exhibited the most substantial increases among the treatments. Monthly evaluations revealed that treatment T2 (AMF 2 combined with NPK) resulted in maize plants with remarkable heights of 188.44 cm, while T1 (AMF 1 with NPK) enhanced leaf length. Additionally, treatment T4 showed significant dry matter retention, highlighting the effectiveness of these combined nutrient strategies. The findings suggest that integrating AMF with organic and inorganic fertilizers can optimize maize yield, and offer a sustainable strategy for smallholder farmers in Tanzania to enhance productivity in the face of nutrient challenges.

Equipment of dairy cattle manure treatment organic fertilizer

Now we can see that many dairy farms, chicken farms and other farms are going to buy organic fertilizer equipment. Why? First of all, because the org​anic fertilizer production equipment can treat the manure of livestock and poultry into organic fertilizer, which fundamentally solves the pollution caused by the manure of livestock and poultry, so that the environmental problems in the farm can be solved. In addition, the organic fertilizer produced can not only be used on its own land, but also be sold, and the profits from the sale can be As the circulating fund of the farm, and the organic fertilizer has been proved to have a very good regulating effect on the soil through experiments, and can also protect the soil from being damaged and nutrient loss, which is the benefit that the organic fertilizer equipment can bring to people.

With the increasing use of organic fertilizer equipment, how to choose a suitable and economical organic fertilizer production equipment?

https://www.organic-fertilizer-machinery.com/production-line/organic-fertilizer-production-line.html

​1. There are two common factors in purchase. The price of organic fertilizer equipment that customers first consider, but the utilization rate of equipment is often not valued. In fact, the utilization rate is also valued for users to purchase equipment, and whether the utilization rate reaches a reasonable value investment. Take the organic fertilizer equipment price, quality and utilization rate as our solution.2. Secondly, for farms or fertilizer processing enterprises, it is inevitable to choose a complete organic fertilizer production line whether it is powdered organic fertilizer or granular organic fertilizer. There is a big gap between the price of the complete set of organic fertilizer equipment and the initial processing investment price. The complete set of organic fertilizer production line includes organic fertilizer granulator, disc granulator, dryer and other granulation processing equipment.3. Different use methods of organic fertilizer equipment are different, and the manufacturing process and products are also very different, so we should first consider what we are mainly used for, and then choose the equipment. Many users are mainly used for making granular fertilizer, and some are used for composting, so the use is different for different purposes. If we want to improve the quality of soil, then we can choose multi-functional organic fertilizer granulator, which can meet our use of organic fertilizer processing, and the price is cheap, and the operation is very convenient.

How to turn cow manure into fertilizer?

In many rural areas, cow dung or simply just cattle manure is commonly used widely in gardens. However, when compared to others, cow manure isn't actually abundant in nitrogen, nevertheless it comes with a relatively higher level of ammonia that may damage plants and burn them. Plants may be easily burned when cow manure is applied right to them. Our article is put into more information on how to make fertilizer from cow manure.

A safe and efficient method to use cow manure on plants is to compost it and you'll essentially reap advantages by doing so. Cow manure is literally consisting of nutrients and organic materials. However, they do contain just around 3% nitrogen, 2% phosphorous and naturally the famous 1% potassium. So when we've said before, it can actually contain a serious high level of ammonia together with a group of dangerous pathogens.

Due to above reasons, cow manure must be composted or aged to make sure that it can be safe to be used as a fertilizer. When properly composted, you'll be able to apply cow manure without worrying about weed seeds, pathogens and ammonia. And you'll have the capacity to easily add the compost to your soil and reap the organic benefits which come with it. However, due to the moisture holding capabilities, you'll also be able to water your plants much less.

When you water your plants less, the fresh roots can easily use nutrients and water each time they should need them. And you'll be also improving the aeration for your plants since heavily compacted soil will likely be easily split up. Composted manure also contains the beneficial bacteria that is needed for converting your nutrients into an readily available form for your plants plus they prevent burning.

In relation to the manure composting production  process, you'll should firstly pick a location that may be suitable for developing a pile that is roughly a 4-foot square. It's also good to remember that you'll should also turn the pile so make sure that you have sufficient room. Next you'll must spread about 3 inches of dry organic material layer to the square area. Then you'll spread roughly 2 inches of cow manure.

You're going to have to continue layering until your pile is around 4 feet in height. Then you'll need to water your pile to make certain that it is completely damp even towards the bottom. After you've dampened your pile, you'll have to give a layer of soil. About every three days or more, you're likely to must turn your compost pile as a way to allow the air flow in it.

You'll should also make sure that your pile stays moist. And you'll need to periodically examine the temperature if you turn it so as to keep the temperature at its optimum level. After the composting process is completed, you'll see that it is dark brown, with the earth smell in fact it is quite crumbly.

When we conclude we certainly have just investigated the best way to compost cow manure to turn it into fertilizer. So we have discussed the numerous advantages of cow manure fertilizer. So, understand that you can't apply fresh cow manure until you've composted it!

Ornamental Aquatic Plant Nutrition: A Study on Qualitative and Quantitative Differences in Morphological Traits of Waterwort, Elatine gratiloides a Cunn | Chapter 06 | Emerging Issues in Science and Technology Vol. 3

Aim: To evaluate the efficacy of different organic substrates on quantitative and qualitative morphological traits of freshwater ornamental aquatic plant, waterwort (Elatine gratiloides).

Place and Duration of Study: Ornamental Fish and Aquatic Plant Unit, Department of Aquaculture, College of Fisheries, Guru Angad Dev Veterinary and Animal Sciences University Ludhiana (Punjab), India, from 11th April 2016 to 10th September 2016.

Methodology: An experiment was designed as per the principles of completely randomized block design with five treatments viz., control (T0) - without any manure, only soil/sand mixture (2:1), while vermi compost (T1), poultry manure (T2), cattle manure (T3) and goat manure (T4) @ 2% in triplicate in the mud pots of 3.5 L capacities.

Results: From the performance of waterwort with respect to different organic manures, it was observed that, there was considerable increase in plant biomass, total plant length, number of leaf and runners containing high nitrogen content. Among all treatments, poultry manure (T2) illustrated superior results and showed significant difference among the treatments, except for the cattle manure (T3).

Conclusion: Due to the easy availability of cattle manure in local market at affordable price compared with poultry manure; it is recommended that application of cattle manure @ 2% with soil/sand mixture (2:1) helps to increase plant biomass along with other parameters including plant length, number of leaves, number of runners with high nutrient value in terms of nitrogen content for culture and propagation of ornamental aquatic plant waterwort.
