RING/PIT METHOD OF PLANTING IN SUGARCANE

-
Ring planting (90×45cm) system increased the crop yield up to 180t/ha at IISR. In each ring (pit) about two to three budded setts are placed horizontally in a circular manner. The crop under ring planting consists mainly of mother shoots which are thicker and heavier.
Suitable for:
  1.   Drought prone areas
  2.   Undulating topography
  3.   Light textured soils
  4.   Saline – sodic soils
  5.   Multiple ratooning
  6.   High yielding, tall and thick varieties
  7.   However, labour and capital intensive
  8.   High speed requirement





Merit and limitations of pit planting:

Merits-
  1. Less irrigation water is require.
  2.  Nutrient use efficiency is enhancing due to localized placement.
  3. Increase the opportunity of employment generation.
  4. Higher sugarcane yield of plant cane as well as ratoon.
  5. Greater efficiency of solar energy utilization.
  6. Prevent lodging both for plant cane and multi-ratoons.


Limitations:
  1. Less availability of pit digger machine for making ring/pit in the field.
  2.  More requirement of labour for manual pit making, mixing of manure and fertilizer with soil in the pit, covering of set with soil.

TYPES OF GREENHOUSES

-

Greenhouse structures of various types are used successfully for crop production. Although there are advantages in each type for a particular application, in general there is no single type greenhouse, which can be considered as the best. Different types of greenhouses are designed to meet the specific needs. GREENHOUSE TYPE BASED ON SHAPE Greenhouses can be classified based on their shape or style.    For the purpose of classification, the uniqueness of the cross section of the greenhouses can be considered as a factor.    As the longitudinal section tend to be approximately the same for all types, the longitudinal section of the greenhouse cannot be used for classification. The cross sections depict the width and height of the structure and the length is perpendicular to the plane of cross section. Also, the cross section provides information on the overall shape of the structural members, such as truss or hoop, which will be repeated on every day. The commonly followed

Mist Chamber and Its components

-
What is mist Chamber? Enclosed structure in which artificially mist is generated for the propagation of Plants or seedlings. In Mist Chamber, Relative humidity is maintained at high level (95 %) with the help of mister’s, which spray water under high pressure. Size of mist partials lies between 50 to 100 µ m. High relative humidity facilitate better root initiation and cooling effect prevents the cutting from drying out.   Advantages of mist chamber          This method results in faster rooting of the cuttings.          Create optimum Microclimate for better root initiation and development.          Higher success rate found in propagation of hard wood cuttings. Disadvantages of mist chamber Hardening of rooted cuttings is more difficult and requires careful attention. Selection of right medium is very important. Under mist conditions oxygen deficiency can create problem.   Components of mist chamber ESSENTIAL  COMPONENTS Structure: Galv

GREENHOUSE TYPE BASED ON COVERING MATERIALS

Covering   materials   are   the   major   and   important   component   of   the   greenhouse   structure. Covering materials have direct influence on the greenhouse effect inside the structure and they alter the air temperature inside the house. The types of frames and method of fixing also varies with the covering material.    Based on the type of covering materials, the greenhouses are classified as glass, plastic film and rigid panel greenhouses. Glass greenhouses Only glass greenhouses with glass as the covering material existed prior to 1950.   Glass as covering material has the advantage of greater interior light intensity.    These greenhouses have higher air infiltration rate which leads to lower interior humidity and better disease prevention.   Lean-to type, even span, ridge and furrow type of designs are used for construction of glass greenhouse.
