An experiment entitled, “Studies on effect of different paddy cultivars with various cultivation methods of paddy in relation to weather parameters.” was carried out during kharif, 2018 at Agricultural Research Station Farm,Vadgaon Maval, Tal. Maval, Dist. Pune. The field experiment was laid out in split plot design with three replications. There were sixteen treatment combinations comprising of four varieties viz., VDN-3-51-18 (Indrayani), VDN-99-29 (PhuleSamruddhi), IET-13549 (Bhogawati) and RDN-99-1 (Phule Radha) and four cultivation methods viz., M1 : Four Point Agro Technique (Char Sutri Method), M2 : Drilling at 22.5 cm, M3: Saguna Rice Technique (SRT) and M4 : Modified Direct Seeded Rice Technique (MDSRT). The gross plot sizewas3.40 m x 3.40 m. From the data it was observed that sowing of paddy varieties with Modified Direct Seeded Rice Technique (MDSRT) favorably influenced all the yield components. This is due to positive correlation with minimum temperature, RH I and RH II. It would be, therefore, suggested to adopt sowing paddy variety Phule Samruddhi or Indrayani with Modified Direct Seeded Rice Technique (MDSRT) to obtain maximum yield.

“…The number of productive tillers showed no significant differences among the different sowing time (Table 3) conforming to the findings (Iwuagwu et al, 2017) who reported no statistical significant differences in number of tillers under four levels of planting dates. However, the number ranged from 8.58 to 10.27 corresponding to sowing done on 14 Jul and 29 Jul, respectively.…”

Generally, rice is sown late March-April in high altitudes, early May-June in mid altitudes and June-early July in low altitudes in Bhutan. Sowing times of rice in Bhutan are often driven by the monsoon and are frequently delayed with no specific varieties developed for delayed sowing. Thus, the research was conducted at ARDC-Samtenling research station in 2017 to study effect of sowing dates on performance of widely adopted Bhur Kambja1 rice variety to identify zonal specific optimum sowing window. Field experiment was laid out in a randomized complete block design with three replications having net plot size of 5×2 m. Experiment comprised of five different sowing dates that are 30 th May, 14 th June, 29 th June, 14 th July and 29 th July at an interval of 15 days. Some agronomical traits such as plant height, days to maturity, number of productive tillers per hill, panicle length at harvest and grain yield were measured and analyzed. The result indicated that effect of sowing dates on plant height, days to maturity, panicle length and grain yield were statistically significant at 0.05 probability level while number of productive tillers per hill showed no significant differences among different dates of sowing. Sowing at 30 th May and 14 th June resulted significantly higher yield of 3.53 t ha -1 and 3.40 t ha -1 respectively. The findings revealed that sowings at 29 th June, 14 th July and 29 th July yielded low of 2.37 t ha -1 , 2.97 t ha -1 and 2.83 t ha -1 respectively. This elucidates that late sowing and transplanting cause yield reduction which could not be recommended among farmers.

Rice is globally the most important food crop and there is a dire need to feed the ever-increasing population by improving its productivity. It has been realised that diseases are the major impediment towards enhancing the productivity of this crop. Despite the advent of modern effective disease control measures such as use of chemicals, bioagents and resistant varieties; agronomic practices still play a vital role in disease management in rice. Optimum use of different agro-techniques can be exploited for efficient control of various devastating diseases like rice blast, sheath blight, bakanae and many more by providing a favourable environment to better crop survival. Besides, appropriate selection of a variety, use of quality seed, method of establishment, planting time, nutrient, water and weed management practices can be well exploited to control various diseases. This manuscript entails to review the work pertaining to use of agronomic practices for exploiting the potential of crop environment interaction through reduced disease infection and to bridge the yield gap for ensuring sustained food security.
