Efficient use of fertilizers in Cotton crop. (Assessment)

 

No. of Location : 6
Area per Location: 0.375 ha

 

Results:- Use of fertilizers as per recommendation with foliar application of Urea phosphate, NPK and Potassium sulphate had realized a net return of Rs 56902/ha as compared to recommended practices with net return of Rs.50412-/ha (12.87% increase in net return per hectare).

 

Evaluation of chilli varieties . (Assessment)

 

Chilli, which is also known as hot pepper (Capsicum annum var. longum L.) is an important vegetable as well as spice crop grown extensively in tropical and subtropical area in India. All released varieties of chilli may not be cultivated successfully in every pot of the Country. So, the different varieties evaluated the specific area. Kranti variety gave higher yield and better in quality as compare to other varities. It is a long duration variety and gave the production almost throughout the year.

No. of Location: 5
Area per Location : 0.125 ha

Results:- Kranti variety gave higher yield and better in quality as compare to other varities. It is a long duration variety and gave the production almost throughout the year.

 

Evaluation of spacing in cauliflower. (Refinement)

 

Cauliflower (Brassica oleracea var. botrytis L) is one the most popular winter vegetable grown throughout the country. It is grown for its white tender curd, which is used as raw or cooked as vegetable. Among cole crops, cauliflower following cabbage is important with regard to area and production. Recommended spacing for cauliflower planting is 45 x 45 cm but the farmers normally apply closed spacing 30 x 20 cm. Therefore, there is need to evaluate the planting space in cauliflower.

No. of Location : 5 Area per Location : 0.075 ha

Results:- Wider and closed spacing effect size and compactness of curd. In optimum spacing 45 X 30 cm farmer get higher yield with compact and solid curd.

Citrus psylla management in Kinnow orchard. (Assessment)

• Citrus is the third major fruit of India after mango and banana. In northern part of Rajasthan, Kinnow mandarin is cultivated in larger area. In Hanumangarh district kinnow mandrain covered 1916 ha area. Kinnow is attacked by number of insect-pest throughout its life. Out of these, citrus psylla is an important pest, which cause sometime 30 per cent loses in Kinnow orchard alone. This pest also transmits huanglongbing (greening) disease in citrus fruits.
• Farmers of the area are generally using Difenthuron 50wp @ 1 gm per litre of water, which is not effective to control citrus psylla. Some new molecules are available in market, which may be found effective for the same. Therefore, there is a need to check the efficacy of new effective molecules.
• Kinnow is an important fruit crop of Hanumangarh district. This crop is suffered from high incidence of sucking pest like citrus Psylla throught the year. Due to the incidence of citrus Psylla, cause fruit dropping, check the plant photosynthesis and ultimately fruit yield loss. So that KVK, Sangaria design a on farm trial of new molecules for sucking pest management in Kinnow at six defferant locations in Hanumangarh district, Nearby 1 RTP, 3 RTP, 4 STP, 12 BGP and 11 MJD.

No. of Location : 6
Area per Location: 0.75 ha

Results:- The assessed technology (spray of Trizophos 40 EC @ 2.5 ml/lt – Imidachlorprid 17.8 SL @ 0.33 ml/lt - Thiomethoxam 25 WG @ 0.5 ml/lt) reduced percentage citrus psylla incidence from 18 to 4 and yield was increased by11.65 percent.

 

Yellow and brown rust management in wheat. (Assessment)

 

Wheat is an important cereal crop of northern Rajasthan. However, there is high incidence of yellow and brown rust in pactches resulting in yield losses. Eight locations namely Lambidhab, Jandwalasikhan, Basir, Sangaria and Pratapnagar villages conducted On- Farm trial to assess the control measuers. The assesed technology spray of Azoxystrobin 23 SC @ 1.00 ml/litre reduced the percentage of disease incidence from 14 to 5 and yield was increased by 7.65 percent.
