Dried Papaya Leaves as Organic Mulch for Tomato Plants

Mulching in agricultural provides a safe yet equally profitable method of enriching and fertilizing the soil planted with crops. Most often-used mulches are of organic composition, such as dry leaves and barks. Unlike synthetic fertilizers and herbicides, these organic mulches pose no or little damage to the soil and crops. In this study, the effectiveness of dried papaya leaves as organic mulch for tomato was tested. Papaya mulches in different thickness were applied on plots planted with tomato in three replications. After the determined period of mulch application, the researchers application, the researchers measured the height increases of tomato plants and the weed density in the plots. It was concluded that papaya mulch significantly promoted height increase of tomato plants and inhibited the growth of weeds. The best mulch was 3 inches in thickness. Introduction

Usually defined as the use of organic and biodegradable materials to give plants the nutrients they need, organic farming proved to be the safest and most effective method of increasing and sustaining yield. Various methods fall under organic farming, such as composting, green manuring, legume inoculating, and utilizing animal manure as fertilizers. Mulching is a simple process that increases soil fertility and regulating several factors affecting overall plant growth. In this method, a layer of material-the mulch-is placed on soil surface around the plant. The mulch is used to retard the growth of weeds, protect roots and stems from sudden or extreme temperature changes, reduce soil erosion by wind and water, retard runoff of rainfall, prevent soil pudding by breaking the impact of raindrops, and keep flowers and fruits from being spattered with mud during rainstorms. Hypotheses

1. Treatment 2 (black plastic mulch) was the most effective mulch for growing eggplant in terms of:a. Controlling weedsb. Insect Countc. Number of damaged and undamaged fruits. Weight of damaged and undamaged fruits

2. There was a significant difference among the treatments in terms of:a. Controlling weedsb. Insect Countc. Number of damaged and undamaged fruits. Weight of damaged and undamaged fruits

3. Treatment 2 (black plastic mulch) was the most effective mulch for growing eggplant in terms of producing undamaged fruits.

Significance of the study
Nowadays, various processes and methods have been considered inorganic farming such as composting and utilizing animal manure. These methods have been proven in giving excellent growth and development of plants. One of the techniques in organic farming that have been used today is mulching, either dry or wet season. It is very effective in conserving soil moisture for the plants, prevents growth of weeds, can lessen the use of chemicals like insecticides and pesticides, keep flowers and fruits from being spattered with mud during rainy days, keeps the soil cooler during summer and keeps warmer in rainy season .Numerous recyclable materials are found in our surroundings such as barks, leaves, rice straw, sacks and plastics that can be used for some agricultural purposes like mulching and these materials can be used as an organic fertilizer for plants. Furthermore, rice straw, sacks and plastics has been proven as mulch for plants. If these materials were used properly, it would be a big benefit to the humanity particularly to the farmers .It is for this reason that, the researchers thought of exploring the comparison between rice straw, black plastic and white old sack as mulch for eggplant in terms of number of weeds ,number of insects, number and weight of fruits. Through this, the farmers will have comprehensive information about the differences between the different mulching materials. In addition, this study can help the farmers to lessen the use of chemical products and will contribute to the protection of the environment for not using synthetic...
