The electronic device, ‘Mizu Ha’, controls the various valves for irrigation spread across the entire plantation area, using Internet of Things (IOT). These valves control various Sprinklers, Drip lines, and Mist Systems dedicated to particular plantation beds. An interactive User Interface enables the User to monitor the plantation area using a mobile device or a web browser. Mizu Ha is configured to detect pre-set humidity/rain/snow/soil humidity levels (customized as per the planted crop) to override the configured irrigation timers into a ‘snooze’ phase, to pause external water supply temporarily. Mizu Ha is governed by inputs from a remote device and continuously fetches data and stores in the cloud. During any failure, or unforeseen circumstances, the data from the cloud would restore the last saved settings onto the device of that plantation area, to restore its irrigation settings.
Description:
‘Pamuk hamsa’ is a product and system design that functions as a cotton bole collecting and segregating device.
‘Pamuk’ = Cotton (Turkish) and ‘Hamsa’ = Swan (Sanskrit). It is believed that the ‘Hamsa’ had the ability to eat pearls and separate milk from water from a solution of the two.
The entire system is categorized as follows:
-
The Immobile Installation:
-
A grid of vertical Polyurethane coated Bamboo/Cement/Concrete Poles at a distance of 24m from each other. The poles are placed in increasing order of their height, so as to generate a gradient of 8 degrees between the lowest pole and the highest, such that all lowest poles are along the same face of the plantation area.
-
These poles are connected via 10mm diameter thick steel cables and hooks in tension.
-
-
Mobile Components:
-
Specially designed wide-mouthed conical cotton canvas sling carriers, with concentric 50 (fifty) Bio-degradable polypropylene bags, each with an attached string to tie and lock the bag. A set of two such carriers, with different colours (chrome yellow and cobalt blue, so that even colour blind users can identify the two different bags as dark gray and light gray bags, for grade A and grade B quality of Cotton Boles, respectively).
-
A Nylon rope with ‘J-Hook’ on both the ends. One end attaches it (Nylon rope) with the back strap of the collection canvas carrier and the other is attached to the Sheave carrying the harvested cotton in Bio-degradable Polypropylene bags.
Manually propelled Wagon or a motorized one, depending upon the need of the agronomist or the farmer.
Poles erected along the plantation rows and connected with steel cables to maintain a gradient of 8 degrees.

How to use:
-
Erect the Immobile installation in place.
-
Hang the yellow and blue canvas carriers on the two opposite shoulders of the harvester. The laborer envisages the grade of the majority of the harvest, when he/she begins the harvest. Depending upon the same, he/she would hang the corresponding carrier across the torso from the shoulder of his/her preferred hand (right or left) and the other on the opposite side, similar to a sling bag.
-
Check for the Bio-degradable Polypropylene Bags inserted in the carrier. If missing, opt to re-fill (refill pack of 50 such nested bags shall be readily available, and can be stocked).
-
Confirm about 50-60 sheaves in the carrier’s pockets.
-
Successfully attach the Nylon rope, with ‘J-hook’ on both the ends, to the ‘D-Loop’ on either of the carriers and leave the other end loose. (This rope helps to drag the filled Bags along with the laborer, in case the steel cables sag, instead of being taut.)
-
Begin harvesting. (The wide mouth of the carrier aids in successful basket-ing of the cotton-boles, right into the carrier.)
-
The conical shape of the carrier helps in easy squatting while harvesting the Boles from the base of the plant.
-
Once a bag is full, gently compress the cotton inside and use the top to tie a tight ‘running-knot’ with a loop.
-
This loop is hung onto the Sheave’s J-hook and inserted onto the steel cable. The loose end of the Nylon rope is attached to the first bag, so as to drag all the bags thereafter along with the laborer. Usually the bags roll down due to the gradient, but during unforeseen sagging of the steel cable, the Nylon-rope helps to drag them along.
-
Many such bags are hung and dragged along with the laborer till a pole is reached.
-
The process is repeated for each segment and depending upon the size of the farm/land, a wagon is drawn periodically (for smaller farms, it is done pre-lunch and during dusk) and the bags are transported to a central location for storage or trade.
Alternate usage:
-
Along with Cotton plantation, often Marigolds are planted. The system proposed above, can be used to harvest marigolds and other perishable, voluminous agri-produces. This system is extremely effective for horticulture harvest.

-
The cotton boles harvested near the soil are contaminated with dry leaves or soil particles, thereby categorized into grade B or C of the harvest. The cotton harvest near the apex and middle strata of the crop is usually less contaminated as compared to the ones harvested from the base. During the harvest, these two grades are mixed; hence the quality of the entire harvest becomes Grade B or C. This deprives the farmer from the price appreciation of Grade A, which otherwise would be extremely profitable.
-
Harvesting Cotton is an extremely labor intensive process. Major loss of time is incurred in multiple to and fro movements from the area of harvest to the central location where the collected boles are unfilled. Cotton boles are more voluminous as compared to its weight. Hence repeated un-filling is required. This leads to loss of productive time.
-
Due to the large volume of the harvest and susceptibility towards adverse environment, the farmer cannot stock the harvest and sell the produce when the market price is high. This forces the farmer to sell during ‘Buyer’s market’ instead of Seller’s market’, incurring financial loss.
-
The Farmers of the Indian Sub-Continent area sell the entire harvest in the local market/trading hub/marketing yard for agricultural produce, called a ‘Mandi’. These intermediaries at the “Mandi’ take advantage of the illiteracy of the farmer and cheat them over the weight of the produce. The farmer cannot calculate the weight of the produce harvested due to lack of means and awareness.
In situ segregation of Grade A and Grade B of the harvest helps the farmer to reap a better price for the Grade A quality of the harvest.
The system erected comprising of the increasing height o the vertical poles and the connecting cables helps to generate an angle of 8 degrees. This angle helps to roll down the cotton filled bags hung on the J-Hooked Sheave. Thus, the laborer need not make to and fro movements to un-fill the harvest. Each PP Bag (white for Grade B and Black for Grade B) is filled completely and tied and hung on the sheave, ready to roll down. This also gives a tentative idea to the laborer on the quantity harvested per day.
The Bio-Degradable Polypropylene bags isolate the harvest from the external environment and protect it against pest and insect attack, for a period of minimum of 4 months. Hence the produce can be sold at the time when the farmer foresees a better market without the need of renting expensive warehouses.
The Bio-Degradable Polypropylene bags accommodate 1.5kg of the cotton when filled completely and then tied and stored. Hence at the time of selling the produce, the farmer just needs to count the number of bags to be sold and he would have an idea of the weight of the total produce, thereby leaving a very narrow margin for cheating.
