Research on the Cultivation of High Yield Peanuts

Laboratory of Cultivation, Shantung Institute of Peanut   

Abstract: We have carried out experiments to produce high yield of peanuts in the way combining with the mass movement for four years, We established one hundred and twenty plots of high yield about 600–800 jin per mu. Number of plants per mu, number of pods per plant and number of pods per jin are factors constituting high yield. The index of each factor constituting high yield is different in different varieties. The most important among these three factors is the number of pods per fin. For the purpose of stabilizing the number of pods per jin, it is necessary to bring 2-seeded pods up to 60%–90% and full pods up to 50%–80%. The main techniques are to enhance the development of the first and second pairs of lateral branches of peanuts to the greatest extent and to hasten the earlier emergence of the secondary branches in order to increase the percentages of fruit setting and of full fruits. The main measures of high yield culture are as follows: lossen the soil through deep cultivation and soil improvement; regulate the ratio of nutrients in soil by phosphorus dressing; regulate the contradiction of light competition between individual plant and plant population by rational close planting and balance the contradiction between the vegetative growth and reproductive growth by proper cultural measures including stunting, promoting and regulating the growth of plants.
