An Eco-Friendly Aerobic Rice : BI 33 (Anagha)
BI 33 (also known as ARB 6) manifests a very high degree of drought resistance and productivity under water limited conditions. It is a boon to farmers. Agriculture will face challenges in the form of diminishing water resources. Anagha can be grown just like Maize. After direct seeding, irrigation should be given at intervals of five to seven days throughout the season. Irrigation can be skipped in the event of rainfall.
Cultivation practices is detailed below.
Land Preparation: Land is ploughed and made friable for seeding similar to that for crops like Maize, Sorghum, Wheat Pulses etc. Appropriate quantity of compost incorporated into the soil, improves its health and bodes well for the crop. NPK@ 100:50:50 kg/hectare is recommended with N in two splits.
Sowing: Seven to ten kilogram seed is enough for one hectare. Sowing is done in rows, either behind a plough furrow or using seed drill. Appropriate spacing is 30cm between rows and 10-15cm between plants, with the row.Immediately after sowing, in dry soil, irrigate to ensure good germination and seeding establishment. Sow dense and thin seedlings to appropriate spacing.Gap filling is advantageous in maintaining plant population
Weed Management: As the seeds are sown in relatively wide rows, inter-cultivation is easy.For inter-cultivation Kono rotary weeder (or bullock drawn kunte) can be used to loosen soil and control weeds at early stage of the crop.
The weeds are buried in the soil, which helps in increasing organic matter and this promotes proper root growth. Application of pre-emergent(before rice emerges) weedicide, Pendimethalin @ 3 litre/ha helps in minimizing weeds establishment for two -three weeks after sowing. Manual hand weeding is also recommended whenever weed growth is high. Some weeds may serve as green leafy vegetables
Crop Management: Anagha flowers in 79 days and mature in 115-120 days. Incidence of pests and diseases in aerobic rice production system is less compared to irrigated rice. If any diseases incidence is noticed, control measures as recommended in packages of practices of irrigated rice is to be followed
Grain Yield: This depends on soil fertility, soil health and water availability. Grain yields range from 1.9 t/ha under complete rain fed condition to 6.9 t/ha under well endowed and well-managed conditions.Grain are medium slender & have good cooking quality
