Ludhiana, Could 18
Specialists at Punjab Agricultural College (PAU), Ludhiana, have stated transplanting paddy near the onset of monsoon not solely conserves water, but additionally assist cut back the load on underground water.
PAU recommends 11 brief or medium period rice varieties which at the moment are grown on greater than 70 per cent space within the state. “Transplanting paddy round June 25 ends in the very best yield. The range PR 126 performs even higher when transplanted in July. Flowering interval of early transplanted crop coincides with excessive temperature, which ends up in decrease yield as a result of panicle sterility and low grain weight,” stated Dr Gurjit Singh Mangat, Extra Director Analysis (Crop Enchancment), PAU.

He additional stated transplanting early permits pests to have a larger variety of generations. These observations have been seen significantly for stem borers of rice (yellow, white, and pink) in numerous research carried out at PAU.
Dr Buta Singh Dhillon, Principal Scientist, Plant Breeding, stated the heavy build-up of pests, reminiscent of stem borers and plant hoppers, poses a severe menace to the basmati crop, which is extra susceptible and matures late. This compels farmers to resort to heavy sprays, inflicting residue points, thereby undermining export of Basmati. The build-up of the pest on the rice crop past a threshold can show to be a menace even to the succeeding wheat crop as occurred in case of pink stem borer after 2019 rice harvest. Furthermore, false smut and sheath blight illnesses of rice additionally present greater severity in early transplanted rice.
“In view of this farmers are suggested to transplant 30-35 days previous nursery of PR 121, PR 128, PR 129, and PR 130 after June 20. The 25-30 days previous nursery of PR 126 must be transplanted between June 25 and July 10 for greater paddy yields,” stated Dr Dhillon.
Resulting from adequate window between wheat harvest and transplanting of PR varieties inexperienced manuring turned possible which helped enhance bodily and chemical properties of soil, added Dr Mangat.
