Rabi maize cultivation

-

 Dear farmers

Rabi maize favourably responds to better crop management. Rabi yield is higher than Kharif. The average temperature during the growing season should not go below 12°C and there should be no frost.

Sowing time - October to mid November
Sowing method - Sowing on ridges
Sowing direction - Southern side of the East - West ridge
Seed rate/ha - 20 - 22 kg
Spacing - 60×18 cm
Sowing depth - 4-5 cm
Plant population/ha - 90000

Seed treatment

Soaking of seed over night in warm water (45°C at the time of soaking)

Intercultural operation

1 or 2 intercultural operations i.e. hoeing and weeding should be performed.

Fertilizer management

120:60:40 kg NPK dose per hectare is recommended. 30 kg N and full P and K are given at the time of sowing. 60 kg N at knee-height stage and remaining 30 kg N is given at flag leaf stage.

Irrigation

Six irrigations are given to the Rabi maize crop.
  • Two irrigations upto flowering
  • One at the time of flowering
  • Two after flowering
  • One at early grain filling stage

Cropping systems

Maize - Potato
Maize - Wheat
Maize - Potato - Wheat
Maize - Wheat - Sugarcane
Maize - Wheat - Jowar - Sugarcane
Maize - Potato - Sugarcane - Wheat

Harvesting and threshing

Maize is harvested when cob sheath turns brownish and grains become hard containing less than 20 per cent moisture. In hybrids and composites, sheath becomes brown, loose and silk dried completely. In most of the varieties, plants remain green even at full maturity. Maize is harvested either by plucking the cobs from the standing plant or by cutting the stalk and plucking the cobs from the plant. The cobs are dried in sun for 7-8 days. The threshing is done by bitting the cobs with sticks or with the help of corn shelter.

Yield

Under rain-fed situation maize yield 20-25 q/ha grains for hybrids and 15 - 20 q for composites. However, under irrigation, hybrids and composites yielded 50 - 60 and 45 - 50 q/ha respectively.

To ensure high yield-

  • Maintain optimum plant population
  • Better water management
  • Favourable temperature
  • Better response to nutrients
  • Less incidence of insect - pests and diseases
  • Less weed competition should be maintained

Soybean cultivation

Dear farmers,                          Soybean is cheapest, easiest and richest source of best quality proteins and fats with multipurpose uses as food and industrial product. It is therefore called as wonder crop. It is considered as highly nutritive crop containing 40% high quality protein and 20%  oil. Soybean protein is rich in amino acid and lycine (5%); which is deficient in most of the cereals. Climatic requirements for soybean cultivation Soybean is a warm season crop. Its cultivation is now extended to subtropics and temperate climates. It can grow well in areas receiving annual rainfall from 600 to 1000 mm. Soil temperature of 15.5°C or above favour rapid germination and vigorous seedling growth. The minimum temperature for effective growth is about 10°C. Lower temperature delays the flowering. Temperature of 26.5 to 30°C appears to be optimum for most of the varieties. Soybean is basically a short day plant. Day length is the key factor. They are sensitive to photoperiod. th

तूर लागवड आणि सुधारित पद्धत भाग 1

-
शेतकरी मित्रांनो तूर हा भारतीय आहारामधील एक महत्त्वाचा घटक आहे. तुरीला काही भागात अरहर सुद्धा म्हणतात. तुरीला प्रामुख्याने डाळीच्या स्वरूपात खाल्ले जाते. तुरीमध्ये प्रामुख्याने लोह, आयोडीन आणि महत्त्वाचे अमिनो ॲसिड्स आढळतात. तुरीचे कुटार गुरांना खाद्य म्हणून वापरले जाते. हवामान आणि जमीन हवामान:  तुर मुुुख्यत्वे उष्ण आणि समशीतोष्ण हवामानात वाढते. शाखीय वाढीसाठी तुरीला उष्ण व दमट हवामान गरजेचे असते. जमीन: तुर हे पीक रेताळ जमिनीपासून ते चिकणमाती पर्यंत वाढवल्या जाऊ शकते. जमीन पाण्याचा उत्तम निचरा होणारी असावी. जमिनीची मशागत: तुरीची मूळे खोलवर जात असल्याने जमीन 15 सेंमी इतकी खोलवर नांगरून घ्यावी. नंतर 2 ते 3 वाखराच्या पळ्या द्याव्या. पेरणीची वेळ: खरीपातील कोरडवाहू तुरीची पेरणी जून महिण्याच्या शेवटच्या आठव्यापासून ते जुलै च्या पहिल्या पंधरवड्यात करावी. बागायती तुरीची लागवड जून च्या सुरुवातीला करावी. दोन तासांतील अंतर हे तुरीमध्ये 6 ते 9 फूट इतके ठेवावे तर दोन झाडांतील अंतर हे किमान 1 ते  कमाल 2 फूट इतके ठेवावे.  बीजप्रक्रिया: बियाणे पेरण्यापूर्वी कार्बेन्डाझिम किंवा थायरम 3 ग्राम प्रती किलो
