Lower nitrogen fixation generally affects not only the leghemoglobin in the nodules, but decreases also the number of nodules, nodule weight and nodule activity. Drought stress delays the nodule formation, thus depriving crop mineral nutrition during critical pre-flowering stages of crop development. Nitrogen assimilation is also decreased under drought stress due to reduction in the activity of nitrate reductase enzyme. Water is also essential for uptake of nutrients, the fertilizer use efficiency is lower under stress conditions and the response to fertilizer is limited. 

This is particularly true to Ca which is very critical for pod developing and has to be taken up by developing pegs and pod directly. Water is required for continuous supply of water soluble Ca. Effect on reproductive growth and yield - Time to flowering is not modified by drought stress. Only severe water deficits of 35% of field capacity would delay flowering by about 1-2 days. However, the total flower number decreases when drought stress is experienced during the pre- or post-flowering stage. 

Reproductive development from meiosis to seed set is highly vulnerable to drought stress, which can cause pollen sterility, spikelet death or embryo abortion of newly formed seeds in groundnut. Drought stress either reduces or stops peg and pod development based on the degree of stress. OZSTAR has the best roasters of various capacities to give you the perfectly roasted peanuts! We also provide additional equipment for flavouring and seasoning the nuts. OZSTAR also provides additional flavoring and seasoning equipment for nuts We manufacture different capacity to suit demand. This stainless steel is of high quality and can be controlled from the touch screen control panel.

 

The time of peg initiation, rate of peg elongation and pod initiation is delayed or inhibited by drought stress. Pod development is sensitive to drought stress, where it decreases the pod and seed growth. Adequate pod zone moisture is critical for developing pegs to pods; adequate water in the root zone cannot compensate for the lack of pod zone water for the 30 days of peg developing. However, after 30 days adequate pod zone moisture, the pods can continue normal growth even if the pod zone is dry as long as roots can access adequate moisture. 

A decrease in dry matter, flower, peg and pod number, and a delay in peg and pod initiation and pod growth under drought stress conditions individually and in combination contribute to reductions in pod and seed yields. Reductions in pod yield are more pronounced when stress is imposed at the pod development and flowering phases than during the vegetative phase. 

Pod yield decreases in a linear fashion as the intensity of drought increases. The partitioning coefficient decreases from 0.52 (100% irrigation) to 0.24 (33% irrigation) as environments become less favorable. Under drought, already established pods have priority for partitioning of assimilates.
