Agro technology:
1 |
1985 |
Application of 120 kg N /ha to variety CR-138-928 in four equal splits at transplanting, tillering, panicle initiation and boot stages proved advantageous in enhancing the yield. Application of phosphorous and potash however did not prove beneficial. |
2 |
1992 |
The farmers of South Gujarat Heavy Rainfall Zone Situation-III following Paddy –Gram crop sequence are recommended to apply N and P @ 50 kg/ha and 25 kg/ha, respectively to Paddy GR-11 and @10 kg/ha and 20 kg/ha, respectively of N and P to gram Dahod yellow for getting economic return. |
3 |
1992 |
Farmers of South Gujarat Heavy Rainfall Zone are advised to practice green manuring with sunhamp before Kharif paddy and apply 100% recommended dose of N for higher production. Those who cannot offered to apply 100 % N can only 60 % N to get the same yield as 100 % N alone with out green manuring. |
4 |
1993 |
The farmer of Vyara area CAES-III of South Gujarat Heavy Rainfall Zone are advised to give two irrigations to the gram crop through sprinkler method to save 50 % irrigated water. The first irrigation should be applied of the time of sowing and the second irrigation after about 25 days i.e. at branching stage with 50 mm depth of irrigation. |
5 |
1993 |
The farmers of Vyara area (ARS-III) of South Gujarat Heavy rainfall Zone are advised to use sprinkler method of irrigation for summer groundnut crop to have 150 % more income with marginal saving of water. (The sprinkler system should be laid at 12 x 12 m spacing and should be operated at 2.75 kg/cm2 pressure. To get 0.67 cm/hr. application rate, the set should be operated for 2 hrs. 24 min. per irrigation for a total application of 40 mm) |
6 |
1994 |
Farmers of Middle (Zone -III) and south Gujarat (Zone-I) growing rice (Ambica) are advised to apply 180 kg/ha N and 30 kg/ha P205 for getting higher grain yield and net profit. Nitrogen may be applied in three splits at the stages of planting, tillering and panicle initiation in 2:2:1 proportion, respectively. Phosphorus should be applied as a basal dose. |
7 |
1994 |
The farmers growing transplanted paddy variety GR-11 during Kharif in the South Gujarat Heavy Rainfall Agro-climatic Zone (AES-III) are advised to apply 100 kgK2O/ha. in two equal split.

8 |
1994 |
The farmers growing transplanted paddy through hired labour in South Gujarat Heavy Rainfall Agro-climatic Zone (AES-III and IV) are advised to adopt the practice of direct seeding of sprouted seeds in line under paddled conditions. As compared to transplanting it gives 37 % higher net returns. Further by this the crop mature earlier by about one week in case of early variety (GR-3) and by about two weeks in case of late variety (GR-103). |
9 |
1995 |
The farmers of Agro-ecological Situation III of South Gujarat Heavy Rainfall Zone, practicing sprouted seeding are advised to adopt seed rate of 60 Kg/ha with a row distance of 22.5 cm in order to obtain 13 percent more yield. |
10 |
1995 |
The farmers of Agro-ecological Situation III of South Gujarat Heavy Rainfall Zone, cultivating variety GR-103 in summer season are advised to sow sprouted seeds after thorough puddling. This gives 32% more net return over transplanting method. |
11 |
1996 |
The farmers of Agro-ecological Situation III of South Gujarat Heavy Rainfall Zone, growing summer groundnut are advised to sow the crop from December to first fortnight of January. |
12 |
1997 |
Farmers cultivating rabi/summer crop after irrigated transplanting paddy in AES-III of South Gujarat Heavy Rainfall Zone are advocated to adopt paddy) – groundnut\\\'s) sequence in order to get about 167 Percent more net return over existing paddy – gram sequence. |
13 |
1997 |
Farmers of AES-III of South Gujarat Heavy Rainfall Zone growing summer groundnut are advocated to 30 cm spacing with a seed rate of 120 Kg/ha. |
14 |
1998 |
Phosphorus management in green manure paddy sequence Farmers of AES-III of South Gujarat Heavy Rainfall Zone following green manure-paddy (GR-3) sequence in soil of medium phosphorus are advised to apply 30 kg P2O5/ha to green manure instead of 60 kg P2O5/ha to paddy. |
15 |
1999 |
Farmers of South Gujarat Heavy Rainfall Zone (AES-III) are advised to fertilize kharif transplanted paddy with 100 kg N /ha in two equal splits i.e. 50 kg as basal and 50 kg at tillering stage (30 DAT) under Navsari (Jaya) and Vyara (GR-11) conditions. In case, the basal application is missed due to adverse conditions, the entire quantity may be applied at tillering stage. |
16 |
2000 |
Farmers of AES-III of South Gujarat Heavy Rainfall Zone-I growing paddy (GR-5) during kharif are advised to applied 120 kgN/ha. In soils containing high available P2O5, K2O and S these elements should not be applied. |
17 |

Plant pathology :
1 |
1978 |
Considering the importance of false smut disease in South Gujarat areas it is tentatively suggested to spray either Zineb @ 0.1 % a.i. + Copper Oxychloride @ 0.3 % a.i. or Captafol @ 0.1 % a.i. of the boot leaf and dough stage to control false smut. |
2 |

Spray of Disfotatan Captafol 0.1 % @ 1000 l/ha at boot leaf and dough stages is recommended for the control of false smut. |
3 |
