  4. Nutrient management in vegetable crops
The results of demonstrations conducted are as follows

Demonstration of comparision of SRI with conventional paddy

Objective: To demonstrate water saving and high yielding in SRI cultivation compared to conventional paddy.

The results showed that SRI method of cultivation of paddy has given more yield (5010 kg/ha) compared to conventional paddy (4728.57 kg/ha) . The average number of tillers per plant were also high in SRI method with 42 tillers/plant where as only 25 tillers/plant were recorded in conventional paddy.

The quantity of water requirement recorded was less in SRI method of cultivation with 950 mm compared to 1200mm in conventional method.

Regarding pests & diseases, fewer pest and diseases problems were reported in SRI method. It was observed that sheath blight and BPH incidence is low under SRI method compared to conventional method.

Nutrient and water management in SRI cultivation

Objective : To study the effect of Inorganic fertilizers, Organic manures and integrated nutrient management practices in SRI cultivation and conventional paddy.

The demonstration conducted to study the effect of using organic fertilizers in combination with inorganic fertilizers in both SRI method and conventional method of paddy cultivation yielded the following results.

The use of organic fertilizers viz, FYM and Biofertilizers like Azospirillim, PSB,VAM using with inorganic fertilizers (INM) has given good yields in both SRI and conventional method with 6045.71 kg/ha and 5780.21 kg/ha respectiviely in comparision to inorganic and organic treatments.

The next best yields were recorded in Inorganic treatment in both SRI and conventional method of cultivation with 5418.18 kg/ha and 5120 kg/ha.

The organic treatment has recorded less yields with 4406.89 kg/ha in SRI method and 5495.68 kg/ha in conventional method of paddy cultivation.

The water requirement in organic treatment has been recorded less with 850 mm in SRI method and 1100 mm in conventional method compared to inorganic and INM treatments.

Nutrient and water management in Maize

Objective : To study the effect of Inorganic fertilizers , Organic manures and Integrated Nutrient Management practices under sprinkler irrigation in Maize crop.

The results demonstrated that Nutrient management through INMmethod has given higher yields with 5860 kg/ha followed by inorganic 4470 kg/ha and Organic 2550 kg/ha treatments.

The water requirement through sprinkler irrigation was recorded less in organic treatment with any 350mm compared to Inorganic and INM where the water requirement was 400 mm.

Nutrient and Water Management in vegetable crops:

Objective: To study the effect of Inorganic fertilizers, Organic manures and integrated nutrient management practices in Bhendi , French Beans, Tomato and Brinjal.

The Demonstration on Nutrient and Water Management in vegetable crops was conducted to study the effect of chemical, fertilizers (T1).Inorganic fertlizers using organic mannures and Bio Fertilizers in combination with Inorganic fertilizers (INM) (T2) and only organic mannures (T3) for 3 vegitable crops viz Bhendi (C1), Brinjal(C2) and Tomato(C3) has given the following results.

BHENDI CROP (C1)

The use of organic mannures viz FYM and Bio Fertilizers like PSB, and Azospirillum used with Inorganic fertilizers (INM) has given good results in terms of yields in Bhendi crop 12187.50 kgs/ha(T2) when compared to Inorganic treatment (T1) and Organic treatment (T3).

The water requirement in Organic treatment (T3) has been recorded less with 300 mm in Bhendi crop when compared to Inorganic(T1) and INM treatment(T2) where it is 400mm.

The incidence of pests and diseases like fruit borer and powdery mildew diseases were observed very low In organic treatment(T3)when compared to Inorganic(T1) where it was High and moderate in INM treatment (T3).

BRINJAL CROP(C2)

In case of Brinjal crop also the Treatment INM (T2) has given good yields i.e, 8687.5 kgs/ha compared to Inorganic treatment (T1) and Organic treatment (T3). The next best yields were recorded in Inorganic treatment (T1) 8350 kgs/ha. The organic treatment (T3) has recorded less yields i.e, 6400 kgs/ha among all the treatments. The water requirement in Organic treatment has been recorded less with 450mm in Brinjal crop when compared to Inorganic and INM treatment 550mm.The incidence of pests and diseases like fruit and shoot borer, sucking pests were observed very low for Organic treatment(T3) comared to Inorganic(T1) and INM treatments(T2) where it was observed high and moderate respectively.

TOMATO CROP(C3)

In case of Tomato crop the treatment INM (T2) has recorded good yield i.e, 14,275 kgs/ha compared to Inorganic treatment (T1) which recorded 12,800 kgs/ha and Organic treatment (T3) recorded 11,200 kgs/ha

The water requirement in Organic treatment (T3) has been recorded less with 400 mm in Tomato crop compared to Inorganic (T1)and INM (T2) treatment which has recorded 500mm. the incidence of pests like Fruit borer and diseases like leaf blight were observed very high in Inorganic (T1) and moderate in INM (T2) where as very less in Organic treatment (T3).

The following Demonstrations were conducted during Rabi 2007-08.

  1. Nutrient and water management in SRI method of cultivation
  2. Nutrient and water management in Maize
The results of demonstrations conducted are as follows

Nutrient and water management in SRI cultivation

Objective : To study the effect of Inorganic fertilizers, Organic manures and integrated nutrient management practices in SRI cultivation and conventional paddy.

The demonstration conducted to study the effect of using organic fertilizers in combination with inorganic fertilizers in SRI method of cultivation yielded the following results.

The use of organic fertilizers viz, FYM and Biofertilizers like Azospirillim, PSB,VAM using with inorganic fertilizers (INM) has given good yields. With 5428.57 kg/ha in comparision to inorganic and organic treatments with yields recorded 4914.29 kg/ha and 4571.43 kg/ha respectively.

The water requirement in organic treatment has been recorded less with 850 mm in comparision to inorganic and INM treatments with consumption of 950mm and 900mm.

Regarding pests & diseases, fewer pest and diseases problems were reported in SRI method. It was observed that sheath blight and BPH incidence is low in all the treatments.

Nutrient and water management in Maize

Objective : To study the effect of Inorganic fertilizers , Organic manures and Integrated Nutrient Management practices under sprinkler irrigation in Maize crop.n

The results demonstrated that Nutrient management through INMmethod has given higher yields with 2066 kg/ha followed by inorganic 1800 kg/ha and Organic 1600 kg/ha treatments.

The water requirement through sprinkler irrigation was recorded less in organic treatment with only 3000mm compared to Inorganic and INM whare the water treatment was 350 mm.
