The protein content of peanuts increases with increasing irrigation

The researchers found that the protein content of peanuts increased with increasing irrigation.
Arman Gilani, Master of Irrigation and Drainage, Faculty of Agriculture, Tarbiat Modares University, in order to investigate the effect of different managements on yield and quality of peanuts under drip irrigation system, conducted a research in a completely randomized design in 2009 in Astana Ashrafieh.

Explaining this research project, he said: Irrigation treatments included (TO) without irrigation, 75% of the plant’s water requirement (T75), 100% of the plant’s water requirement (T100) and 125% of the plant’s water requirement (T125).

Referring to the results of this study, Gilani added: The results showed that the highest grain yield and peanut pod were obtained in T100 treatment and the lowest grain and pod yield was obtained for T0 treatment. The percentage of peanut protein increased with increasing irrigation, the lowest of which was observed in the treatment of 20% (T0) and the highest in the treatment of T125 (24%). Increased irrigation was inversely related to oil percentage, so that the percentage of peanut oil in T0 treatment had the highest value and in T125 treatment had the lowest value.

He added: Economic results also show that the maximum profit is always achieved in terms of maximum yield, so that with the construction of irrigation systems in a peanut farm, irrigation should be done optimally to maximize production and thus maximum profit. Otherwise, due to the high initial costs of building the system, the costs will exceed the revenue and the net profit will decrease. In this study, the highest net profit has been obtained for T100 treatment.
