New Insights for Promoting the Plant Growth and Germination and Applications in Agriculture

Abstract

Drought is a generally prolonged period of dryness which creates significant damage to crops and prevents their effective growth. It can also refer to a prolonged period of extremely low precipitation, especially one that has a negative impact on growing or living conditions. Drought affects plants vary, depending on the various stages of the plant's growth and the duration, severity and frequency of the drought. During high concentration germination decreases with increasing level of drought. Water deficiency also reduces the dry biomass of seed and seedlings. Drought stress causes the decline in seedling of wheat. The field experiment was conducted by utilizing augmented block design. Augmented block design is used when a limited quantity of resources available for experiment. From upper position of the spike excluding awns to the soil surface in centimeter were noted before harvesting. Spikes from each plot were selected randomly and number of spikelets was counted starting from base of spike towards the spike end. Under drought, plant height, spikes, peduncle length of selected plants was affected and had significant differences during normal irrigation and rainfed conditions. Grain yield per plant had highly significant positive correlation spike length under water irrigation.
