Weeds can pose a significant threat to the growth and health of your tomato plants. Competing for sunlight, nutrients, and water, these invasive plants can hinder the development of tomatoes, leading to poor growth or even failure. This article aims to explore common weed types that affect tomato plants during seedling stage and provide recommendations for effective weed management. Additionally, we will discuss the use of manual weeders and herbicides as practical solutions, emphasizing the importance of careful application to protect your tomato plants. 

Types of Weeds

To effectively manage weeds in your tomato farm, it is crucial to understand the different types commonly encountered. Weeds can be categorized into three main groups: 

  • Broad-leaved weeds 
  • Grassy weeds and  
  • Sedges 

Broad-leaved weeds: These weeds typically have smaller and wider leaves compared to other types. These plants compete directly with tomato plants for essential resources. 

Grassy weeds: As the name suggests, grassy weeds have longer and narrower leaves resembling grasses. 

Sedges: Sedges are similar to grasses, but they are distinguished by their cylindrical, triangle-shaped stems and three leaves.  

Methods of Weed Removal

To mitigate the adverse effects of weeds on your tomato plants, effective weed removal methods can be employed. The two common approaches are manual weeders and herbicides. 

Manual weeders

Manual weeders are hand tools specifically designed for uprooting weeds from the ground. This method is suitable for those who prefer not to use herbicides or have limited access to them. Manual weeders are also favored in organic farming practices. 

Herbicides

Herbicides are chemical compounds designed to eliminate weeds. They can be categorized into two types based on their application. 

  • Pre-emergence herbicides: Pre-emergence herbicides are weed killers that are applied to the soil before the weeds start growing. They create a protective barrier on the soil surface, preventing weed emergence.  
  • Post-emergence herbicides: Post-emergence herbicides are applied directly to the weeds after they have emerged from the soil. They target and kill the existing weed growth.

Land Preparation For Tomato Crop

0

Are you planning to grow tomatoes? That’s fantastic! But before you dive into the exciting planting process, it’s important to ensure that your field is well-nourished and properly prepared.  In this article, we will be sharing some valuable insights on the best practices for making your field ready for a successful tomato crop. So, let’s get started! 

Best Practices for Preparing Your Field for Tomato Cultivation

Tilling or Ploughing

The first step in preparing your field is tilling the land, also known as ploughing, which involves cutting, breaking, and inverting the soil. Tilling mechanically loosens and breaks up the soil and also helps in creating an optimal environment for seed germination and root growth. This process enhances air and water flow to the plant roots, thereby promoting healthy development.  

Tilling the land also ensures that the minerals present in the soil are well-mixed and easily accessible to the crops, further enhancing their growth. This step sets a strong foundation for your tomato cultivation. 

Note: While tilling is crucial, make sure that you are not over-tilling the soil, as excessive tilling can lead to the loss of soil structure and fertility, erosion, and damage to beneficial soil microorganisms. Striking a balance between loosening the soil for planting and maintaining its overall structure and health is essential. 

Harrowing

The next step after tilling is harrowing, which smoothens and pulverizes the soil to a shallow depth. It helps create a finer seedbed and prepares the soil for subsequent operations. 

Harrowing is followed by the application of Farmyard Manure (FYM). FYM supplies nutrients and enhances the solubility and availability of nutrients in the soil. It also boosts microbial activity, further enriching the soil. 

Recommended dose of FYM: 12 tons of FYM/acre  

Making Ridges and Furrows

The last step in tilling involves making ridges and furrows. These make intercultural operations easier throughout the growth cycle.  

Recommended spacing for ridges and furrows: 60-75 cm. This specific spacing helps prevent the spread of pests and diseases, ensuring the overall health of your tomato plants. 

Application of Biofertilizers and Bioagents

To further enhance soil health and protect against pests and diseases, consider using beneficial microorganisms.                                                                                                            

Recommended beneficial microorganisms: Trichoderma, Pseudomonas, and Paceliomyces. 

These beneficial microorganisms can be mixed with neem cake, Pongamia cake, and FYM for improved results. 

Application method: Broadcast the basal dose 7 to 10 days after applying biofertilizer.  

Setting up the Irrigation-Drip System

Additionally, for improved irrigation and water use efficiency in your tomato field, it is recommended to lay down inline drip lateral pipes. 

Recommended pipe specifications: Use pipes with a diameter of 12 or 16 mm. 

Note: These pipes should be laid at a 2-feet distance throughout the field. 

Conclusion

Remember, a well-prepared land is crucial in tomato cultivation as it lays the foundation for a high-quality yield. Make sure to follow the best practices and essential steps listed in this article for optimal crop growth and a higher yield.

Bahar Treatment In Pomegranate For High Quality And Yields
Bahar Treatment In Pomegranate For High Quality And Yields

Have you been wondering why your pomegranate trees produce flowers profusely, yet fail to give luscious and marketable fruits you desire?  

If you are looking for a solution to this persistent problem, then you are in the right place. We have the ultimate solution to vanish your worries – Bahar Treatment. Don’t stop here. Read further to know why, when and how to perform this cultural practice (Bahar treatment) to transform your pomegranate orchard with abundant and flavourful fruits. 

What is Bahar treatment? 

Bahar treatment is a horticultural practice which involves controlling vegetative growth by pruning and inducing flowering at specific desired season to improve yield and fruit quality. 

What is the purpose of doing Bahar treatment? 

Pomegranate trees have the ability to flower throughout the year as long as they receive sufficient moisture in the soil. However, allowing continuous flowering leads to irregular fruiting with smaller size, making it commercially unfeasible with low yields. Therefore, pomegranate trees are subjected to Bahar treatment to regulate their flowering and fruiting patterns. 

Besides synchronizing the flowering to increase yield, other purposes served includes, 

  • Pruning and thinning increases airflow, reduces humidity and minimizes the risk of pest and disease attack. 
  • It helps improve fruit quality. It allows the remaining branches to receive more sunlight and nutrients, resulting in better fruit color, size and flavor. 

Right timing to induce flowering 

In tropical conditions, pomegranate cultivation experiences three distinct flowering seasons: ambia bahar, mrig bahar and hasta bahar. The choice of flowering season is determined based on factors such as irrigation water availability or rainfall, market demand and incidence of pests and diseases in the specific area. 

Flowering can be induced during three specific periods based on the patterns of rainfall: 

  1. Mrig bahar (June-July) 

  • It is advantageous in areas with assured rainfall starting in June and continuing until September.  
  • Harvesting time: December to February. 
  • This season is favoured as flowering and fruiting coincide with the rainy season or immediately after rains. 
  1. Hasta bahar (September-October)

  • It is beneficial in areas where the monsoon typically starts in August with an erratic pattern.  
  • Harvesting time: March to April. 
  • Due to their visually appealing rind, dark-colored arils and limited availability during this season, they have higher market value.  
  1. Ambia bahar (January-February)

  • This is suitable for areas with assured irrigation facility during April-May or where the monsoon starts early and withdraws by September, allowing for the induction of flowering in October.  
  • Harvesting time: June to September.  
  • This season is suitable for export-quality fruits as the dry weather during fruit development contributes to attractive color and quality. 

Steps to perform Bahar Treatment 

It is physiology of the plant system in perennial crops that stress promotes flowering, so in case of pomegranate the science of forcing plants for moisture stress is considered. 

Step – 1: Stop giving irrigation at least 30-35 days prior to bahar treatment in case of light sandy soil and 40-45 days or even 2 months in case of sandy loam soil.  

Step – 2: Prune the trees for proper canopy (40 – 45 days after stopping irrigation). 

Step – 3: Within 2 days after pruning, spray Ethrel 2.5 ml/lit + DAP  5 gm/lit of water on the pruned trees for defoliation, and just after defoliation (80 – 85% leaf fall), light pruning (15-25 cm) is done.  

Step – 4: Within 2-3 days after pruning, apply the required amount of nutrients* to the soil. The nutrients suggested below is for 2 – 5 year crop and subsequently the quantity of the nutrients or fertilizers have to be increased based on the crop age and plant size.  

Nutrient  Manure/Fertilizer  Dosage (per plant) 
Organic  FYM  20 kg 
N  Ammonium Sulphate  2 kg 
P  Single Super Phosphate (SSP)  1.6 kg 
K  Muriate of Potash (MOP)  1.3 kg 
Zn  Chelated liquid zinc  3 – 5 ml/lit of water 
Mg  Magnesium Sulphate (0.2%)  2 gm/lit of water 
B  Boron 20%  1 gm/lit of water 

 

Step – 5: After applying the above nutrients and cover them with soil i.e., earthing up and then give light irrigation. The quantity of water to the plants in first irrigation after applying manures and fertilizers may be little more (8 – 12 liters/plant based on plant age and size) but for next two consecutive days the quantity of water must be half of quantity provided in the first one.   

  • Excess irrigation at this stage should be avoided otherwise flowering will be affected adversely. 
  • After 3rd irrigation, stop giving irrigation for 5-6 days. 

If the above steps are followed timely and without fail, it will result in profuse flowering and better fruit set. Initially more male flowers appear and subsequently, hermaphrodite flowers appear and produce fruits. Regular plant protection (Pest & Disease) measures should be followed throughout the cropping season. 

(NOTE: Bahar treatment should be done to the crop age of more than 18 months and based on plant growth.)

Whitefly in Cotton Control Measures

If you notice any of the symptoms mentioned above in your cotton field, implement an integrated pest management strategy that includes cultural, mechanical, biological and chemical measures to control their infestation. 

Whitefly in Cotton Cultural Measures

  • Avoid late sowing to reduce the whitefly infestation. 
  • Cultivate white fly tolerant varieties like Amravathi, Kanchan, Supriya, Lk 861, LPS 141. 
  • Perform crop rotation with non-preferred hosts like sorghum, ragi, maize etc. 
  • Avoid using excessive dozes of nitrogenous fertilizers, as this can lead to succulent growth which encourages whitefly population. 
  • Remove the alternate weed hosts like Abutilon indicum, Solanum nigrum from the cotton fields and neighboring areas. 
  • Maintain healthy plant growth by providing adequate irrigation. 

Mechanical Measures

  • Collect and destroy the whitefly infested leaves from the cotton plants. 
  • Install Tapas Yellow Sticky Traps at the rate of 6 to 8 traps per acre to effectively control whiteflies in cotton field.
