Abstract

A roving survey of Kaithal and Karnal district of Haryana was conducted during Kharif 2021 to assess the constraints in rice crop production. A total of 24 soil samples from the surveyed sites were collected in triplicate for further analysis. The pH(1:2) and EC(1:2) of the surveyed sites ranged from 7.5 to 9.2 and 0.15 to 0.74 dS/m, respectively. The surveyed soils were non saline in nature. Most of the surveyed sites (around 80%) were found medium in organic carbon status. Available nitrogen ranged from 135-198 kg N/ha, available phosphorus 29.31-53.59 kg P2O5/ha and available potassium 223.2-392 kg K2O/ha in the surveyed sites. The grain yield of rice varieties ranged from 11-99 q/ha whereas the straw yield of rice varieties ranged from 19-119.5 q/ha. The commonly grown rice varieties in scented group were PB 1121, PB 1509 and CSR 30 while the common high yielding non-scented varieties were PR114, PR 126, PR 121. The commonly grown hybrid was 27P-31. Application of sub-optimal doses of herbicides, pesticides and insecticides, raising of nursery in unpuddled fields and rice- wheat sequence were the common practices in all the surveyed districts. The soil related constraints mainly include low organic carbon (some sites) and low nitrogen status of soil, excessive nitrogen fertilizer dose, improper time of nitrogen fertilizer (urea) application and no use of organic source by most farmers

Keywords

Roving survey, grain yield, straw yield, available nitrogen, nitrogen fertilizer and varietal spectrum.

Conclusion

Based on the observations recorded and intensive interpretation of the results it can be concluded that nitrogen was the most limiting primary nutrient in the surveyed site soils. Low organic carbon (some sites) and low nitrogen status of soil, excessive nitrogen fertilizer dose, improper time of nitrogen fertilizer (urea) application and no use of organic source by most farmers were the major constraints in rice production. However, the famers were advised to apply recommended dose of fertilizers as per CCS Haryana Agricultural University for sustainable crop production. The use of organic manures was also suggested for maintaining organic carbon and soil health
