On Farm Trails are conducted on different crops after diagonising the problems in specific areas of the district. Various multilocational trials on farmer's field are laid for assesment of proven technology and its refinement to suit the local conditions.

1
Effect of weedicide on the productivity of wheat variety PBW 343.
Severe Infestation of weeds
 Results of the trials conducted at farmers’ field at two different locations revealed that there was 30.32 per cent increase in yield over farmers practice (Iso-proturon@750g/h) compared to Sencor@175-200g/h. The B:C ratio in case of Sencor was highest (4.30) as compared to Isoproturon (farmer practice) i.e. 3.21. Sencor@175-200g/ha may be used for effective control of weeds in wheat
2
 Performance of different varieties of Maize. Low production of Kanchan-612 in the area. Results of the trials conducted at farmers’ field at two different locations revealed that there was 15.38 per cent increase in yield(30.50qt/ha) with KH-517 as compared to 26.50 qt/ha with farmers practice (KH-612). KH-517 should be adopted for higher yield
3
 Evaluation of Mustard as Trap Crop for Diamond Back
Moth (DBM) and cabbage butterfly in Knol-khol
 Low production due to damage by the insect-pest Trials were conducted at two different locations on farmer’s field. The results revealed that maximum yield(211 qtls/ha) was harvested when one row of mustard was sown after every five rows of knol-
khol.
Knol-khol should be transplanted in rows at
recommended space and one row of mustard should be sown after every five rows of knol-khol.
4
 Management of brinjal fruit and shoot borer (Leucinodes orbonalis) Yield loss due to attack of brinjal fruit and shoot borer. Results of the trials conducted at farmers’ field at three different locations revealed that there is 20.15 % increase in yield when crop was sprayed with Hamla as compared to Farmer practice (Endosulphan). The B.C ratio in case Hamla was found 1.98 compared to farmer practice i.e. 1.62. Hamla (Cypermethrin + Chlorpyriphos) is more effective than endosulphan and Karate and should be used for management of brinjal fruit & shoot borer.
5
 Varietal Performance in Knol-Khol Low productivity Results of the trials conducted at farmers’ field at two different locations revealed that the variety Purple Vienna gave 15.21% more yield (265q/h) than white Vienna (F.P.) 230q/ha whereas the variety King of Market gave 17.85% more yield (280q/h) than white Vienna. The average knob weight of king of market appeared to be 300g compared to 225g in case of white Vienna (F.P.) and 268g in case of Purple Vienna. The B.C ratio for King of Market was highest (2.32) compared to 2.21 for purple Vienna and 1.60 for white Vienna. ‘King of Market’ variety may be encouraged for large scale production
6
 Nutritional Management on yield of strawberry Strawberry is not cultivated commercially in Poonch. For increasing production, the standardization of nutritional dose is required. Results of the trials conducted at farmers’ field at two different locations revealed that there is 46.91% increase in yield in case of Recommended dose (100-200-80)kg NPK along with 50 t FYM/ha compared to 214.2q/ha over farmer practice (FYM & improper Inorganic fertilizers) i.e. 145.8q/ha. The B.C ratio in case of recommended dose was found highest (2.70) compared to farmer practice i.e. 1.38 Recommended dose (100-200-80)kg NPK along with 50 t FYM/ha may be used for increasing production of strawberry
7
 Response of Tomato hybrid (Shivalik) in Poonch Low productivity Results of the trials conducted at farmers’ field at three different locations revealed that there is 60% increase in yield (240q/h) of tomato from Shivalik hybrid compared to the farmer practice of local variety. The B.C ratio in case of Shivalik hybrid was 4.45 whereas that of local was 3.16. Shivalik hybrid performed well under Poonch
8
 Effect of spacing on yield of cauliflower (Snowball-16) Low productivity Results of the trials conducted at farmers’ field at two different locations revealed that there is 21.95% increase in yield (250q/h) of cauliflower over farmer practice when planted 45 x 60 cm apart and 29.26% increase (265q/h) when planted 30 x 45 cm apart. The B.C ratio in case of 30 x 45 cm spacing was found highest (2.45) as compared to 45 x 60 cm (1.92) & farmer practice (1.30). Cauliflower may be planted at 30 x 45 cm spacing for getting higher yield and economic returns.
9
 Effect of Pruning & Thinning of fruits on yield of Plum: Low Productivity Results of the trials conducted at farmers’ field at three different locations revealed that there is 34.80 % increase in yield when plants were spaced at 45 x 60 cm apart compared to Farmer practice. The B.C ratio in case of 45 x 60 cm spacing was found 4.1 compared to farmer practice i.e. 2.90. 45 x 60 cm spacing may be used for higher yield
10
 Economics of High density planting in Knol-Khol (White
Vienna)
 Low productivity Results of the trials conducted at farmers’ field at two different locations revealed that the high density planting in knol-khol (15 x 30cm) gave 26.08% higher yield (290q/h) over farmer practice . The yield of knol-khol at 20 x 30cm spacing was 275q/ha. The B.C ratio with 15 x 30cm spacing was highest (2.45) as compared to 20 x 30cm spacing (2.28) & farmer practice (1.60) High density planting in knol-khol may be encouraged for increasing production
11
 Effect of nutritional doses on cost & return on cauliflower
(Snowball-16)
 Low productivity Results of the trials conducted at farmers’ field at two different locations revealed that there is 30.24 % increase in yield (267q/h) of cauliflower over farmers practice (205q/h) when NPK was applied @ 150:80:60 and 26.83 % increase (260q/h) when NPK applied at 120:60:60. The B.C ratio in case of 150-80-60 was highest (2.21) compared to 120-60-60 (2.01) & farmer practice (1.30). N P K may be applied @ 150-80-60 for increasing production.
12
 Effect of mulching on yield of Plum in Agri-horticulture based Agroforestry system Fodder scarcity. Results of the trials conducted at farmers’ field revealed that there is 75 % increase in yield of Robinia pseudocasia when 75% pruning of the side branches was done compared to no pruning at all 75% pruning of the side branches should be done.
