An Agricultural Testament by Sir Albert Howard

Although some concepts of organic farming predated his work, today Sir Albert Howard (1873-1947) is regarded by most as the founder and pioneer of the organic movement. Born into an agricultural life, he never strayed far from it. Raised on a farm in England, and educated at Cambridge, he served for a time (1899 -1902) as mycologist in the Imperial Department of Agriculture for the West Indies, before returning to England to teach agricultural science from 1903-1905 at South-Eastern Agricultural College at Wye. He then moved to India where, for twenty-six years he directed several agricultural research centers before permanently returning to England in 1931.

It was after his return that he became well known for his concepts and philosophy of organic farming. Drawing on his many years of agricultural research experience, he wrote several widely read books espousing his concepts and theories of composting, soil fertility, and health and disease.

In 1943, Howard published the book, An Agricultural Testament, in which he described a concept that was to become central to organic farming--the importance of utilizing available waste materials to build and maintain soil fertility and humus content.8 According to what he called "the Law of Return," he strongly advocated the recycling of all organic waste materials, including sewage sludge, back to farmland.

In Farming and Gardening for Health or Disease (later published as Soil and Health), Howard introduced the idea that disease, whether in plants, animals or humans, was caused by unhealthy soil and that organic farming techniques would make the soil and those living on it, healthy.12 As evidence he cited his observations that animals fed with crops grown in humus-rich soil were able to rub noses with diseased animals without becoming infected. More generally he argued that crop and animal health was a birthright and that the correct method for dealing with a pathogen was not to destroy the pathogen but rather to try to learn from it or to "make use of it for tuning up agricultural practice."

Clearly Howard favored the study of whole systems over reductionism. Such a study comparing organic and non-organic farms was attempted from 1939 to 1969 in England by Lady Eve Balfour. Her observations from this comparison of whole farms were described in her widely read book The Living Soil and The Haughley Experiment first published in 1943 and republished in 1974.

Tomato Cultivation -- Kissan Kerala

TOMATO (Lycopersicon esculentum)

 

PlantCharacteristics

Tomato is a tropical vegetable belonging to the family Solanaceae. The ripe fruits are used as vegetable, salad, soup and in the preparation of sauce, jam and ketchup. The fruit is a rich source of vitamin A and C.

Top...

Varieties

Bacterial wilt resistant varieties: Sakthi, Mukthi, Anagha High yielding variety: Pusa Ruby

Top...

SeedsAndCultivation

Seed rate: 400 g/ha Raising seedlings Tomato is a transplanted vegetable. Seeds are sown in the nursery and one-month-old seedlings are transplanted to the main field. For sowing the seeds, raised seed beds of 90 to 100 cm width and of convenient length are prepared to which well decomposed organic matter has been incorporated. After sowing the seeds, mulch with green leaves and irrigate with a rose-can daily in the morning. Remove the mulch immediately after germination of the seeds. Restrict irrigation one week before transplanting and irrigate heavily on the previous day of transplanting. Time of planting Transplant the seedlings during October-November for an irrigated crop. Land preparation and transplanting Land is prepared to a fine tilth by thorough ploughing or digging. Well rotten organic manure is incorporated in the soil and seedlings are transplanted in shallow trenches / pits / levelled lands. Transplanted seedlings may be given temporary shade for three to four days during hot days. Spacing Transplant the seedlings at 60 x 60 cm. Stake the plants if necessary

Top...

WaterManagement

Irrigate at two or three days interval.

Top...

NutrientManagement

Apply well rotten farm yard manure / compost @ 20-25 t/ha at the time of land preparation and mix well with the soil. A fertilizer dose of 75:40:25 kg N:P2O5:K2O / ha may be given. Half the dose of nitrogen, full phosphorus and half of potash may be applied as basal before transplanting. One fourth of nitrogen and half of potash may be applied 20-30 days after planting. The remaining quantity may be applied two months after planting.

Top...

WeedManagement
  Weeding followed by fertilizer application and earthing up may be done at one and two months after transplanting.
PestManagement

Tomato fruit borer attacks developing fruits forming bore holes. Application of Sevin 50 per cent WP @ g/litre of water is effective against this pest. The fields and bunds should be kept weed free to minimize the attack of Thrips.

Top...

DiseaseManagement

For avoiding damping off of the seedlings in the nursery, sow the seeds as thin as possible in raised beds prepared in the open area. Spray nursery and main field with 1% Bordeaux mixture at monthly intervals. Uproot and destroy the plants affected by bacterial wilt and mosaic. Cultivate resistant varieties like Sakthi, Mukthi and Anagha in bacterial wilt prone areas.

 Top...

Harvesting

The fruits are harvested at breaker stage( when ¼ of the surface shows ripening symptoms).

Top...

Processing

Not Available

Earthen pot offers a bounty of benefits for Kanyakumari ryots

M.J. PRABU

The timing is very important for spraying this formulation

Easy practice: Women farmers being trained to manufacture the mud pot nutrient in Kanyakumari district, Tamil Nadu.

The farmers of Kozhikodupothai in Kanyakumari district, Tamil Nadu, have a traditional knowledge base regarding bio-pest repellent formations and also plant growth promotion formulations.

One such traditional formulation called Manpannai sedi thailam in Tamil (Mud pot formulation) combines the effects of both fostering nutritional growth as well as being a pest repellent.

Field experiments

Initially the formulation was experimented with in a small area owned by a rose cultivator Ms. S. Thangam, and was found to completely obviate the need for chemical fertilizers. In addition, Panchagavya was also used for her rose plants.

"The mud pot formulation on my rose plants had a good effect on the size, yield and growth of flowers. In fact all the flowers had a deep colour and a longer shelf life. The flowers after plucking remained fresh for 2-3 days when kept at room temperature," said Ms. Thangam.

Natural farming

In fact she was featured in a video at London for the Ashden Award presentations that showcased Vivekananda Kendra-Natural Resources Development Project (VK-Nardep)'s efforts at increasing food production through natural farming practices.

Ms. Thangam's adoption of this innovation encouraged other farmers to try it. Though initially reluctant to stop using chemical fertilizers, they experimented on a small scale first.

The economic benefits that each farmer incurred created a cascading effect. For example, two years ago, Ms. Thangam was spending about Rs.3,500 for an acre of rose cultivation. At present her expenditure for an acre has come down to Rs. 1,300.

Decreasing expense

"Using this mud pot formulation and following organic practices has greatly decreased the expenditure I was regularly incurring when using chemical fertilizers," she said.

Who was responsible for developing this mud pot plant nutrient?

Mr. Aravindan, social scientist, of the kendra said, "an eminent organic farmer and retired agricultural officer, S. Murugan, is responsible for developing this formulation. He had developed a local plant formulation method with a traditional technique practised in Madya Pradesh."

"Once this formulation was tested successfully in Ms. Thangam's rose field, we decided to give training to more farmers in making this formulation, which has almost been forgotten."

According to Mr. Aravindan, about 100 gms of Vitex, Neem and Calotropis leaves each, 50 gm of powdered pulses (any pulse), one litre of curd or thick butter milk, and 1.5 litres of water are the basic items required for making this formulation.

The leaves are first ground into a fine paste. The paste is then mixed with the powdered pulses (any pulse).

This mixture is then added to one litre of curd. To this is added 1.5 litres of water. The mixture is kept in a mud pot and the mouth covered with a cloth.

The mixture is stirred every day in a clockwise and anticlockwise direction. After 15-20 days the formulation is ready for use. The formulation is diluted in 20 litres of water and sprayed in one acre of crop. The spraying is done on the foliage. The timing is very important for spraying this formulation. The best time is just before dawn and after dusk.

Effective control

The spraying effectively controls several pests and serves as a growth promoter and nutrition provider for the plants.

"Organic inputs have multiple advantages. Apart from reducing input costs, they also keep the environment safe from toxicity.

If one compares a field where chemical fertilizers have been used to grow the crops and a field where organic inputs such as farmyard manure, vermicompost and panchagavya have been used, one can clearly see the presence of earthworms, millipedes and ants is more in an organic field," Mr. Aravindan explained.

Useful organisms

"Our kendra conducted studies for the presence of earthworms and ants in different fields. We found that chemical inputs greatly disturbed the presence of these useful organisms and in several fields where chemical fertilizers were used these organisms were totally absent.

"Once some of the farmers started switching over to organic practices, we were able to observe the presence of these organisms again in the soil," he said.
