Wheat grain yield consists of three components: spikes per plant, grains per spike (i.e. head or ear), and grain weight; and the grains per spike can be dissected into two subcomponents: spikelets per spike and grains per spikelet. An increase in any of these components will directly contribute to grain yield. Wheat morphology biology tells that a wheat plant has no lateral meristem that forms ...

a field experiment was conducted in 2010, to evaluate the effects of plant density (d1, d2 and d3: 8, 14 and 20 plant/m2) on field performance of sorghum under different nitrogen application rates (n1, n2 and n3: application of 40, 80 and 120 kg/ha nitrogen, respectively). the experiment was arranged as factorial based on randomized complete block design in three replicates. results indicated t...

A field experiment entited “Effect of different sowing dates and varieties on growth yield barley (Hordeum vulgare L.) Under Prayagraj conditions” was conducted during the Rabi season 2021-2022. The set at forestry Sam Higginbottom University Agriculture Technology Science U.P. laid out Factorial RBD with three replications having two factors. First factor comprised 15oct. 30 Oct. 15 Nov. where...

Leaf developmental traits are an important component of crop breeding in small-grain cereals. Surprisingly, little is known about the genetic basis for the differences in barley (Hordeum vulgare L.) leaf development. The two barley row-type classes, i.e., twoand six-rowed, show clear-cut differences in leaf development. To quantify these differences and to measure the genetic component of the p...

Frequent and intense defoliation of grasses has been associated with the evolution of “grazing morphotypes” that exhibit a variety of vegetative traits correlated with improved grazing resistance. While recovery from a seed bank is not considered an important grazing resistance mechanism, relatively little is actually known regarding seed (caryopsis) production in grazing morphotypes of caespit...
