SULPHIDE DEFICIENCY

 SYMPTOMS:

  • Sudden foul smell of hydrogen sulphide resembling that of rotten eggs emits from soil
  • A black mark will be seen on the roots if plant is pulled out and examined, which turn to  reddish brown when exposed to air.
  • The crop starts wilting, older leaves become yellow and dry out prematurely
  • Parched appearance of field will be observed.

 

CORRECTION:

  • Application of nitrogenous fertilizer through neutral fertilizers like Calcium Ammonium Nitrate (CAN)
  • Draining of soil frequently will reduce the sulphide injury.

Rice ecosystems in India

Rice is the staple food for more than 65% of population in India. It is cultivated in several agroecological regions. Rice farming is highly widespread and practiced under diversified soil and climatic conditions; hence there are wide variations in variety, methods of cultivation and. soil and water management practices followed. Rice ecosystems in India can be grouped into following categories.

• Irrigated
• Rainfed Rice Eco System: (i) Upland
(ii) Low land
• Flood Prone Rice Eco System

Irrigated Rice Eco System:

The total area under irrigated rice in India is about 22 million hectares, which accounts about 49.5% of the total area under rice crop in the country. Irrigated rice is grown in bunded fields; Irrigation is the main source of water in the dry season and is used to supplement rainfall in the wet season. The major irrigated rice-cropping systems in India are rice-rice, rice-rice-rice, and rice-wheat. The average yield is 4–5 t ha-1. Major problems encountered in this production system are yield instability and environmental degradation due to and unbalanced nutrient use, inefficient irrigation water management.

Rain fed Rice Eco System:

Practiced in the areas with rain fall.>1000mm and scope of irrigation is limited. The rainfed rice area is about 24.4 million. The productivity is very low (< 0.98 tones/hectare), due to uncertainty of available water.

Rainfed Upland Rice Eco System

Upland rice area in India is about 6 million hectares which accounts13.5% of the total area under rice crop in the country. The areas lies in eastern zone comprising of Assam, Bihar, Eastern M.P., Orissa, Eastern U.P., West Bengal and North-Eastern Hill region. Upland rice is mostly grown as direct seeded. Fields are unbunded. This is almost a subsistence crop with minimum input. Productivity is very low (< 1ton/ Ha) and unstable due to drought, weeds, light textured and less fertile soil, nutritional imbalances, poor cultural practices, diseases, insects, and a lack of suitable varieties.

Rainfed Lowland Rice Eco System:

It is usually transplanted, and is grown in levelled, bunded fields that retain surface water, but the depth and duration of flooding of the soil varies greatly from year-to-year within a growing season. Depending upon the depth of water it can further classified to shallow water (<50 cm), semi deep water (50-100 cm) and deep water (>100 cm). The water supply is variable, and both drought and flooding may occur in the same season. Rainfed lowland rice system is also classified as favourable, drought-prone, submergence-prone, and drought- and submergence-prone Soil fertility is low and problem soils are common in this ecosystem. Most of the farmers are resource poor. In India, low land rice area is about 14.4 million hectares, which accounts 32.4 % of the total area under rice crop in the country. Production is highly variable.

Flood Prone Rice Eco System

Flood-prone rice is adapted to conditions of temporary submergence of 1-10 days, or long periods (1-5 months) of standing water ranging in depth from 50 cm to 400 cm or more, or daily tidal fluctuations that sometimes may also cause complete submergence. Flooding occurs during the wet season from June to November, and rice varieties are chosen for their level of tolerance to submersion. During the flooding period the land may be fallow or be used for alternative purposes, such as fish and shrimp farming. In India 11.4 % of total rice grown area is flood prone, yields is low (1.5 ton/ha) and variable.

Control of moths in stored grains

The Angoumois grain moth is the most serious pest injurious to rice, both in the field and storage.

This moth also attacks other cereals like maize, wheat and sorghum.

The infestation may reach serious levels before the grains are transported to the storage godowns resulting in around 25 per cent loss in weight and seed viability.

Internal pest

The larva is an internal borer of the whole grain, feeding on the starchy part. Severely infested material emits an unpleasant smell and looks unhealthy in appearance.

Grains are often covered with scales shed by the moths. The grains are practically hollow and filled with larval excreta and other refuse making it unfit for consumption.

The adult is a small, straw coloured moth. The female can lay an average of 150 eggs on unhusked paddy grains.

They hatch in a week’s period. Newly hatched caterpillar is yellowish white in colour with a brown head capsule. It soon bores into the grain and feeds on its contents.

Larval stage lasts for about three weeks. Before pupation, the larva constructs a silken cocoon in the cavity made during feeding and turns into reddish brown pupa.

After a period of 4-7 days, the adult emerges. Entire life cycle is completed in 30-35 days.

Several generations are completed in a year. Adults are short-lived and can be seen flying about in large numbers in storage bags and on the surface of grains.

Management

— Drying the grains under sun for three days to reduce moisture content below 12 per cent is suggested.

— The jute bags to be used for storing grains have to be dipped in insecticidal solution of fenitrothion 50EC at 5ml/20 liters of water.

— Application of dichlorvos (DDVP) 76SC is recommended on the surface of stored jute bags by dissolving 7ml/lit. of water and the spray solution is sprayed at three lit/100 sq.m.

— Male moths can also be caught in sticky traps baited with female sex pheromone.

நெற்பயிரில் இலைச் சுருட்டுப் புழுவை தடுக்கும் முறைகள்

 வேளாண்மை உதவி இயக்குநர் ராஜசேகர் விவசாயிகளுக்கு வெளியிட்டுள்ள அறிக்கையில் கூறி இருப்பதாவது நெல்லை மாவட்டம் கடையம் வட்டாரத்தில் பரவலாக நடவு செய்யப்பட்டுள்ள நெற்பயிரில் இலைச்சுருட்டுப்புழுக்களின் தாக்குதல் அதிகமாக காணப்படும். பெத்தான்பிள்ளைகுடியிருப்பு, சம்பன்குளம், ஆம்பூர் பகுதிகளில் சாகுபடி செய்துள்ள சாவித்திரி நெல் பயிரில் இலைசுருட்டுப்புழு தாக்குதல் அதிகம் காணப்படுகிறது.
இப்பூச்சிகள் பெரும்பாலும் இரவு நேரங்களில் காணப்படுகிறது. மழை குறைவாகவும், மேகமூட்டமாக இருக்கும் சூழலில் இவற்றின் தாக்குதல் அதிகமாக இருக்கும். தாய் அந்துப் பூச்சிகள் வெளிரிய பழுப்பு நிறத்தில் பளபளக்கும் மஞ்சள் கலந்த பழுப்பு நிற இறக்கையுடன் காணப்படும்.
வயல்கள் மற்றும் வரப்புகளில் உள்ள புற்களை நீக்கி வயலைச் சுத்தமாக வைத்திட வேண்டும். அதிகமாக தழைச்சத்து அதாவது யூரியா போட்ட வயல்கள், குருனை மருந்தான போரேட், கார்போபியூரான் போடப்பட்ட வயல்களில் பாதிப்பு அதிகமாக காணப்படும். நிழல் உள்ள இடங்களில் மற்றும் பயிர் நெருக்கமாக அதிக தழைச்சத்து பெற்று வளமாக இருக்கும் இடங்களில் முதலில் தாக்குதல் தென்படும் தழைச்சத்து ஒரு ஏக்கருக்கு 25 கிலோவுடன் 35 கிலோ பொட்டாஷ் உரத்தை இரு தடவையாக பிரித்து இடவேண்டம். மேலும் ஒரு ஏக்கருக்கு டிரைக்கோ கிரம்மா கைலோனிஸ் ஓட்டுண்ணியை 5சிசி என்ற அளவில் வாரம் ஒரு முறை வயலில் உலவ விட்டால் இப்பூச்சி தாக்குதலை கட்டுப்படுத்தலாம்.
பூச்சி மருந்தை காலை அல்லது மாலை வேளைகளில் வயலில் நீரை நன்கு வடித்துவிட்டு ஒரே மருந்தை திரும்ப திரும்ப தெளிக்காமல் மருந்துகளை சுழற்சி முறையில் அடித்து பூச்சிகளை தடுக்கலாம். இவ்வாறு அவர் தெரிவித்துள்ளார்.
