Trend in linear manner has been observed for wheat production under irrigated timely and late sown along with rainfed timely sown trials of Northern Hills Zone of country. Production elevated to the level of 53, 30 and 36q/ha for irrigated timely, late sown and rainfed timely sown trials. By the end of considered period 0.81, 0.61 and 2.06 quintal per hectare could be added in subsequent trials. Low values of R2 for irrigated timely and late sown trials suggested marginal increase in linear fashion in production values. More over consistent improvement observed in rainfed timely sown trials as justified by highly significant value of R2.
