Newshub18:Boro rice cultivation system.Dual preparation of land should be done for Ropa Aman and Boro. Namely preparation of seed bed and production of seedlings and preparation of root land.
Seed bed preparation and seedling production:
The first step in planting aman/boro is to prepare the seed bed and produce seedlings. Seedlings are prepared in both mud and dry conditions. But during Boro only clay seed bed is done.
Mud Seedbed Preparation:
Elevated land should be selected for seedbeds where monsoon water does not stand. How big the seed bed will be depends on how big the farmer’s original land is. If the original land is one hectare, seedbeds should be made in seven and a half katha land. On a country scale, one bigha of land requires one khata or 70 square meters of seedbed. Below is a step-by-step description of how to create a seedbed in a plot of land.
Step-1: Selecting 10×7 square meters of land. Then apply 200 – 250 kg of dung or compost on this selected land. Then 2-3 plowings are given to the land in such a way that the dung or compost is mixed with the soil.
Step-2: After proper tillage divide (10×1.75) square meters into 4 blocks. The land should be divided by leaving a gap of 25 cm on all four sides of the land. About 30 cm between one part and another part. There will be gaps. And 15 cm from the gap. Deep furrowing of the soil on both sides and raising the seed beds. With the help of this channel, irrigation and drainage of water in the seed bed becomes easier.
Step-3: In this step fertilizer is applied to the seed bed. Urea 250 gm, TSP 250 gm and MP 125 gm sprinkled on seed bed and mud.
Step-4: Sow healthy and nutritious seeds after sprinkling manure and mud.
Dried seedbed clay is prepared like seedbed. For this, 3 kg of seeds should be sown by shaking the soil without mudding the seed bed. And the soil is moistened by flowing water in the drain.
With regular and proper care, the seedlings will grow and after 25-30 days of age, they will be suitable for planting in the main land.
Prepare the main land:
The first task of land preparation is tilling the land. Tillage refers to the loosening of the topsoil of the land with the help of machinery for the purpose of cultivating crops so that the seeds germinate and the crops grow properly.
Preparation of root land for planting:
Seedling Aman, crop of Kharip-II. When there is a lot of rain and the land is plowed 4-5 times and muddled a couple of times with a ladder. Nowadays wet soil can be muddied easily with the help of power tractors with rotovators. The soil contains the roots or litter of the previous crop and is covered in mud. It takes 10-15 days to decompose them properly. When the garbage is completely decomposed, the land is suitable for planting. There is no rainfall during Boro season. Then the land has to be wetted and mudded through irrigation. While making mud on the land, the soil around the field should be cut and fixed with a spade. It becomes necessary to divide the land into several parts according to the slope of the land to trap the water. Otherwise the water goes down the slope to one side. It wastes water and makes it difficult to apply fertilizers.
15-18 cm of the surface in the language of the farmer. The deeper layer is called soil. Therefore, the properties of crop-friendly soil lie in this layer. Almost all crops are grown in the soil of Bangladesh. But soil characteristics of all regions are not same. So it can be seen that paddy is better in some places, wheat in some places, potatoes in some places and jute in some places. Below are the soil characteristics suitable for paddy and wheat crops.
Characteristics of paddy growing soil
» All soils except gravel and sandy loam are suitable for paddy cultivation. Clay and clay loam soils are very good for rice cultivation. Paddy also thrives in river basins and haor-bawar areas where silt accumulates.
» Rice can be cultivated in all types of high, medium, low land. For example, boro and joli aman are cultivated in low lands.
» Acidic to neutral soil conditions are favorable for rice cultivation.
» If the organic matter in the soil is low, its level can be increased by using compost.
» Soil fertility can be increased by using necessary fertilizers by determining the levels of nitrogen, phosphorus, potash, zinc, sulfur etc. in the soil.
Characteristics of soil suitable for wheat cultivation
» High and medium altitude land is suitable for wheat cultivation. Wheat is also cultivated in medium low lands.
» Loam or sandy loam soils are good for wheat cultivation. Wheat is also cultivated in clay-loam soils.
» Wheat cultivation is good in northern districts of Bangladesh. Besides, wheat is cultivated in Dhaka, Comilla, Tangail, Faridpur.
» Not all agricultural regions of Bangladesh grow wheat. Wheat is not grown especially in Haor – Bawar and Beel regions.
» Wheat grows best in soils with pH of 6.0 to 7.0
