Monsoon Cultivation Of Cucumber

Monsoon Cultivation Of Cucumber by Pritham 'Metal Farmer' D'Souza

Cucumber (Cucumis sativus) is one of the most widely used salad crops grown both in North and South India. Fruits contain good amount of Iron and Vitamin C along with carbohydrates. It is highly recommended for people suffering from Jaundice, constipation and indigestion

LAND PREPARATION
since i am mentioning the monsoon cultivation techniques here, the land preparation is very similar to my other posts where i have mentioned monsoon cultivation. Some main points to begin with
  • The land selected must have adequate drainage
  • water logging areas should not be selected
  • however if availability of land is a constraint, seeds have to be sown on elevated bunds as shown below
  • Due to heavy rains, most of the seeds get drowned with too much moisture and they start to rot even before germination, hence more seeds have to be sowed.
  • bunds or raised seed beds should have a minimum height of 10 to 15 inches and seeds once germinated must be thinned out and plant distance maintained


germination seen 7 to 10 days after sowing

the above pic shows water severely logged in the field. the raised seedling bed literally saved the seedlings from rot and drowing.

the photo above shows considerable growth and development of the plant when rainfall recedes and light intensity increases

excess plants must be thinned out and plant distance must be maintained as seen above

INTER CULTURE OPERATIONS AND IRRIGATION
  • Since this is monsoon technique, irrigation is not given, however, due to erratic rainfall patterns, lite irrigation is a must at the time of sowing to moisten the field in case rains fail.
  • while making the raised beds/bunds, decomposed Organic Manure must be added to the soil, and mixed thoroughly and seeds must be sowed on top of this. When the seeds germinate and grow, they will make use of the nutrients present in the soil
  • DO NOT spray the crops during monsoons using pesticides or liquid fertilizers when there is not enough sunlight.
  • Spraying of Liquid fertilizers should be done only when required and in the presence of sunlight. plants prepare their own food during photosynthesis and so sunlight is the most important factor.
  • Soil aeration can be increased by loosening the soil around the root zone of the plants. this also helps in drainage.
the above figure shows rapid development of the plant and tendril stage

soil loosened to provide good aeration and also allow better drainage

MANURING, FLOWERING AND HARVESTING
  • The plant receives the basal dose of decomposed farm yard manure at the time of preparation of the land and sowing.
  • Spray 1 ml seed weed based algae Organic Manure in 1 litre of water at every 10 day intervals. addition of wetting agent like APSA or other sticking agents is recommended so as to increase the effectiveness of the sprays
  • Flowering will be seen 40 to 45 days after sowing and the mature fruits can be harvested after 55 to 60 days after sowing.
  • Timely harvesting the fruit is a must otherwise they over ripe and become unfit for consumption. for salads, the green color of the fruit must not turn brownish yellow.
  • fruits must be plucked every alternate days to avoid over riping
  • for seeds, yellow brown fruits , golden fruits (mature color) are harvested, seeds extracted, washed thoroughly in water and dried
  • the seeds thhus obtained must be sowed again within 3 to 6 months or it looses its viability
  • Cucumber yields up to 100 quintals per hectare

the above pic shows the same stretch of land with excellent growth and flowering

PESTS , DISEASES AND CONTROL
  • I only recommend the usage of pure neem oil @ 5 ml per litre of water to be sprayed only when insect attack is seen
  • Imidochloprid systemic insecticide @2 ml in 5 litre water can be used every 10 days for the young seedlings since they are most vulnerable to sucking pests like aphids, thrips and plant minors. it is also effective in controlling red pumpkin beetle which damages the growing leaves and severely injures the plant
  • Spraying must be done in sunny weather and not in gloomy weather
  • spraying in the evenings from 4pm to 5 pm is recommended than spraying during day time as it will affect pollination
  • adding 2 ml per litre sticking agents or wetting agents is required to increase the effectiveness of the sprays

Indian Spinach (basale soppu, valchi bhajji)


Indian Spinach (Basella alba) also popularly called malabar Spinach, is a distant relative of the Spinach family. It grows as a vine and can attain length of up to 10 meters. it is a fantastic source of iron, vitamin A, vitamin C & calcium. other names are In Kannada Basale soppu, in Konkani Valchi bajji, In bengali pui shak.

The main characteristic feature is the presence of thick mucilage in the leaves & stem, which apart from high nutritive value, also is used in variety of dishes to get thicker gravy, or in soups.

MONSOON TECHNIQUE

Following are the methods used in the cultivation of Indian Spinach Basella Alba under monsoon conditions.

1. Selection of vines
this is the most important criteria for getting a long and steady harvest. The vines can be obtained in the local market , which are sold as wreath bundle. only the best and healthy vines should be used to transplant in the main field while the diseased, old, weak ones are left out. then they are thoroughly washed & kept in a moist place, or water is sprayed on them everyday till the day it is planted.


2. Cutting the vines
Here the selected vines are cut to a length of up to 2 feet, and all the lower leaves removed, keeping only the leaves at the tip/apex of the vine. This is done for polarity to identify which part of the vine is planted in soil & which part is to be trained over a supporting structure.


3. Providing support
since this is a monsoon technique, support must be provided to the growing vines as they should not come in contact with the wet soil, as the growing tips will be succeptable to rot and other fungal diseases.
Making the trellis
  • the land selected to make the trellis to train the vines must have little slope to prevent water from stagnation.
  • rows are dug with width of about 2 feet & pits are made in these rows to a depth of about 2 feet
  • at every 2 meter distance bamboo poles must be placed along the length of the row
  • a concave cut must be made on top of each bamboo pole so that it can support the weight of additional poles and sticks which will be placed on it (see fig 1)

fig 1

fig 2

  • the poles are then tied with the help of GI wire, or rope (see fig 2)
  • between the 2 poles , sticks of certain thickness are placed diagonally as shown and tied with wire or rope.
  • the already cut vines are then planted on the south side of the poles & it is tied with thin rope to make it erect (see fig 3)
  • the growing vines will climb over the trellis , not coming in direct contact with the soil
  • vines will be ready for harvest after a period of over 2 months.
fig 3 erect vines tied with thin rope

fig 4 one view of trellis

fig 5 after 21 days,

fig 6 after 30 days, weak vines must be pruned to allow more shoot development

irrigation
since this is a monsoon technique of growing spinach, no irrigation is needed, however care must be taken to note that at this critical stage of its growth, there must be no water stagnation at the base of the vine. this will result in rotting of the stem & death of the entire vine

Fertilizer application & inter culture
  • at the time of planting the cut vines in the soil, the land must contain good amounts of decomposed farm yard manure and compost.
  • application of certain strains of bacteria also help in quick root formation and absorption of soil nutrients
  • each vine must have a minimum of 2 to 3 buckets of manure. & application is repeated at an interval of 21 days.
  • care must be followed to see that the growing stem does not come in direct contact with the manure. so the manure must be added at a little distance. This is when the vine is just transplanted. since its tender , it might not be able to handle the manure load.
  • At every interval of manure application, weeding must be done & soil is loosened at allow good aeration or it will result is hardening of the soil.

Harvesting

since temperature and light are 2 main limiting factors, the growth of the vines is slow & harvesting can be done on commercial scale only after gap of more than 50 days. but regular pruning of long , weak vines is done at weekly intervals to facilitate growth of new shoots.

when the monsoons subside harvesting can be done after 90 days from date of transplanting.

Bottle Gourd cultivation

Bottle gourd (Lagenaria siceraria) is a widely grown tropical vegetable which has high carbohydrate content. oil can be extracted from the seed kernel and is used in hair care products. the hard shells of the bottle gourd can be used as utensils, or floats in fishing nets and even musical instruments, due to its resonating property.

soil and climate
bottle gourds require well drained and sandy loam soils for its good cultivation. it cannot tolerate higher amounts of acidity, alkalinity or salinity. pH range is between 5 to 5.5 . when soil conditions are not optimum, then production of female flowers is greately affected.
ten days after sowing. thinning out has to be done & min of 2 seeds must be retained in every bed

21 days after sowing.

it can be grown almost in all climates, however, too much rainfall is not good. optimum temperature range is between 30 to 35 degrees during day. if temperature is very high, then more number of male flowers are formed thereby decreasing yield.

LAND PREPARATION, IRRIGATION AND FERTILIZER MANAGEMENT

Since we are discussing monsoon techniques for growing bottle gourds, the land selected must have good drainage. to attain this at least 3 repeated ploughings must be done. raised seed beds are made up to height of 30 cm & distance between beds must be maintained at minimum 2 meters.
irregular leaf shape is due to heavy rainfall & pest attack. spraying with systemic insecticides like dimethoate @ 1 ml per litre every week till plant is healthy is done.
lush green leaves indicates good nitrogen in the soil

in the presence of optimum sunlight, the leaves are able to prepare their own food & the plants appear much more healthy

irrigation is not given during monsoon , but when there is dry spell, light irrigation must be done just to replenish soil moisture. in summer irrigation is carried out thrice a week. if proper mulching is done, irrigation can be reduced to twice weekly.

the 3 photos above show the crop development after a 35 days after sowing. care must be taken to see that the growing vines are free from developing weeds, or it will hinder harvesting.

development of fruits, fruit setting seen


requires good amounts of organic manure. since it is a long duration crop, it is highly beneficial to add manures in split doses. bulky organic manures can be added to the soil every 20 days, while it is good to add complex fertilizers at least once every month.
it responds great to foliar applications as well. the number of female flowers can be increased using plant hormones like NAA, naphthalene acetic acid @ 1 ml per litre, just during flowering stage.
a healthy bottle gourd plant, which seems to be climbing. the vines can grow up to 20 feet, if left unchecked & hence thinning out is done to avoid overcrowding. also distance is maintained between beds for this reason

flowering can be observed. the plant continues to grow & the vines cover the complete area giving a carpet like appearance.

HARVESTING
bottle gourds can be harvested after 55 to 75 days after sowing. care must be taken while harvesting to see that proper tender and ripe fruits must be harvested. the developing tender fruits will have green color & the seed coat & rind are tender. it is best to harvest at this stage. sometimes , harvesting is done depending on the size it attains. smaller fruits are in great demand as compared to bug sized fruits.
when the color changes from green to white, the seed coat and rind hardens & then it becomes over ripe & unfit for consumption. such fruits are kept for formation of seeds, which can be extracted once the fruit completely dries up.


some varieties can yield up to 20 tonnes per hectare.

NOTE
In many cases, especially during monsoon, the growing vines are pruned to allow more lateral branching. vines which are bit old & semi hard are pruned to get the desired result. in some other cases, the vines are allowed to train on coconut ropes grown on bower of bamboo sticks. this is done to prevent the developing fruits from coming in contact with soil & rotting.

ridge gourds grown during monsoon

the seed beds must contain freshly decomposed organic manure. 2 buckets of manure can be added for every seed bed. the main field should have raised seed beds as water stagnation can destroy the young seedlings.
the figure above shows a typical raised bed. 2 to 3 seeds are sowed in every seed bed.

germination will take place after more than a week. under good field conditions, germination is faster. here germination was recorded 8 days after sowing

after 2 weeks after germination. as there is shortage of sunlight, the plants appear weak, even though the seed beds have all the required plant nutrients.

photo taken after 21 days after germination. when sunlight becomes available, growth and development is rapidly accelerated.

using tree branches as support for the growing ridge gourd plants. ridge gourds are climbers & thus require support for its growth.

thinning out must be done & only 2 seedlings must be retained per every raised bed.

2 or 3 sticks with lateral branches are inserted in every bed as shown. care must be taken to see that the sticks do not damage the plant roots or stem.

then the plants must gently be wrapped around the twigs. in 2 datys time, the tendrils will hold the twigs & grow

field shows support given to the plants.

15 days after giving support, the plant is well established & continues to grow using the provided support.

plant seen climbing upwards, the entire length of the support provided.

one month after providing support. the plant has grown very well & climbed the entire length of the support. the lateral shoots that emerge tend to keep falling away from the supporting material. & so the vines should be monitored everyday.

from another angle. as rainfall subsides, the beds need to be opened up & inter culture operations must be continued.


here we can see, the opening up of the raised beds & now pits have been made. 2 to 3 buckets of fresh decomposed manure is added. it is not required to water the pits as moisture content in the soil due to over night rainfall is sufficient for the plant.
only if prolonged dry spells are seen, watering can be done , alternate days, to retain moisture in the soil. at this stage, using complex NPK is also practiced.

another important index is the color green. when the plant is getting adequate nitrogen, the leaves & entire plant has a lush appearance. here the photo shows the plant has attained a height of more than 8 feet & is now slowly covering the trellis/pendall

harvesting can be seen almost immediate after flowering. since it still rains every now and then, incidence of fruit borer is very common. in some cases, tender fruits are harvested earlier to prevent boring of the fruits from the insect.

another view of the same crop. the on off showers increases the incidence of fungus & insects. using strong organic based insect repellents every week is highly recommended. spraying with chemical insecticides is not done as it does not have much impact during the monsoons. repeated sprays are highly toxic to the plant & also unfit for human consumption.
