What are the advantages of hydroponics ?

hydroponics

The increased control over growing conditions in hydroponics makes it easier to provide the best possible environment for plant, leading to better quality produce and high yield. Because the plant does not have to compete for moisture and nutrients, hydroponic productivity can be enhanced by about two times when compared to soil cultivation in a comparable area with proper care. During the changing seasons, a hydroponics garden can feed plants with the best quality nutrients. This will allow for maximum growth to be realised. Because land is not required, a tiny hydroponics garden can be grown up practically anywhere, including upstairs balconies, open areas, and sheltered structures.  In general, hydroponics food tastes better and has a higher nutritional value than conventionally grown crop. .

What are hydroponics?

hydroponics

Hydroponics is a simple technique that involves growing plants in water rather than soil. Hydroculture is a subset of it. Water is dissolved in mineral nutrient solutions. Only the roots of terrestrial plants are exposed to the nutritious liquid, or the roots are physically supported by an inert media such as perlite or gravel. Julius von Sachs and Wilhelm Knop developed the first standard recipe for plant-growing fertiliser solutions dissolved in water. This is where the term “nutriculture” came from. It is now known as Water Culture. The roots of the plants were completely immersed in a water solution containing nitrogen (N), phosphorus (P), potassium (K), magnesium (Mg), sulphur (S), and calcium (Ca) minerals (Ca). They are now known as macronutrients or macroelements (elements required in relatively large amounts).

How grafting is done in grape vines ?

grafting

Grafting is usually done in the months of August and September. During this time, scion material will also be available in the surrounding area, which will save time. High temperature and relative humidity occur in the atmosphere during the grafting period, and the stock plants will also be in the sap flow state, which is a primary need for successful grafting in the field. Temperatures of over 350°C and relative humidity of over 80%, together with the grafter’s competence, aid in the successful grafting of plants in the field.

What is the use of a paddy weeder?

paddy weeder

Paddy weeder does the weeding operation when the seedlings are transplanted in rows. The implement has an inclined long handle. At the fool of it two conical cylinders with serrated lugs on its periphery are fixed. These two conical serrated cylinders can rotate freely about it axis and placed in opposite sides. A steel plate has been into the loose soil and assists in easy operations. In operation, the see rated lugs cut and burry the weeds and some of the weeds are wound on the surface of the cylinders, which can be removed manually.

What are Genetically modified organisms(GMO) and Genetically Modified Food ?

Genetically modified

GMOs are organisms (plants, animals, or microbes) whose genetic material (DNA) has been altered in a way that does not occur normally through mating and/or natural recombination. “Modern biotechnology” or “gene technology” are common terms for the technology, which is also known as “recombinant DNA technology” or “genetic engineering.” It enables for the transfer of specific genes from one organism to another, as well as between unrelated species. GM foods are foods that are made with or from genetically modified organisms.

How seed treatment is done in soyabean ?

soyabean

In soyabean seed treatment is done using fungicides. Biocontrol agents are compatible with biofertilizers. First treat the seeds with biocontrol agents and then with Rhizobium. Fungicides and biocontrol agents are incompatible. Treat the seeds with Carbendezim or  Thiram @ 2g/kg of seed 24hrs before sowing or with talc formulation of Trichoderma viride @ 4 g/kg seed (or) Pseudomonas fluorescens @ 10 g/kg seed. Coat the seeds with ZnSO4 @ 300 mg/kg using 10% maida solution as adhesive (250 ml/ kg) or gruel and arappu leaf powder (250 g/kg) as carrier to increase the field stand.

What is rotational irrigation ?

rotational irrigation

Rotational irrigation is the application of required quantity of irrigation water at regular interval such that there may not be any standing water in field between two irrigations. Irrigation interval is adjusted in such a way that the crop will not experience water deficits at any period. It is usually followed at time of deficit water supplies. Major advantage of rotational irrigation is possibly the more effective use of rainfall.

Which are the critical stages of irrigation for rice ?

critical stages

The critical stage of water requirement refers to the point at which water stress produces substantial yield decrease. It’s also referred to as the moisture-sensitive phase. Critical stages of water requirement in rice are active tillering, panicle initiation, booting, heading and flowering. During theses stages, the irrigation interval should not exceed the stipulated time so as to cause the depletion of moisture below the saturation level.

What is harrowing and what is its purpose?

harrowing

Harrowing is a shallow-depth secondary tillage activity for smoothing and pulverising the soil, as well as cutting weeds and mixing materials with the soil. Soil of the seedbeds are pulverized by harrowing. Harrowing is done to destroy grasses and seeds in the field , to  cut crop residues and mix them with top soil of the field, and to break the big clods and to make the field surface uniform and levelled. Harrowing is carried out when the moisture content of the clods are reduced.

What is Laser Land Levelling ?

Laser Land

Laser land levelling involves utilising a directed laser beam to level the field within a specified degree of desired slope. The germination, stand, and yield of crops are all affected by the unevenness of the soil surface. Farmers are aware of this and dedicate significant effort and energy to properly levelling their fields. Traditional land levelling procedures, on the other hand, are inconvenient, time-consuming, and costly. Laser land levelling helps to increase the efficiency of nutrient utilisation and helps in better water distribution and conservation.
