Effect of Micronutrients on Growth and Yield of Groundnut (Arachis hypogaea L.) Varieties

Abstract

During the summer season of 2022, a field experimental trail on groundnut was performed at Crop Research Farm (CRF), Department of Agronomy, SHUATS, Prayagraj (U.P.) to evaluate the impact of micronutrients on the growth and yield of groundnut (Arachis hypogea L.) varieties. The experimental plot's soil was sandy loam in texture, virtually neutral in soil reaction (pH 7.7), low in organic carbon (0.44%), available N (171.48 kg/ha), available P (27.00 kg/ha), and available K (291.20 kg/ha). The experiment was designed in the Randomized Block Design (RBD) method, with nine treatments repeated three times. According to this trial, the treatments are zinc (0.5%), boron (0.2%), zinc+ boron (0.5%+0.2%) as foliar spray, and varieties. (Kadiri 6, Kadiri 9, Kadiri Amaravati). The treatment combinations are, T1-0.5% Zinc (foliar) + Kadiri 6, T2- 0.5% Zinc (foliar) + Kadiri 9, T3- 0.5% Zinc (foliar) + Kadiri Amaravati, T4- 0.2% Boron (foliar) + Kadiri 6, T5- 0.2% Boron (foliar) + Kadiri 9, T6- 0.2% Boron (foliar) + Kadiri Amaravati, T7- (0.5% + 0.2%) Zn+ B (foliar) + Kadiri 6, T8- (0.5% + 0.2%) Zn+ B (foliar) + Kadiri 9, T9- (0.5% + 0.2%) Zn+ B (foliar) + Kadiri Amaravati. (0.5% + 0.2%) Zn + B (foliar) application with variety Kadiri 6 resulted in greater Plant height (26.60cm), Nodules/plant (49.14), and Plant dry weight (6.56 g/plant). Maximum number of pods per plant (27.87), kernels per pod (2.66), seed index (40.13 g), seed yield (2.48 t/ha), haulm yield (5.67 t/ha), and harvest index (30.44%). Thus, using (0.5% + 0.2%) Zn + B (foliar) in conjunction with the variety Kadiri 6 could be a promising choice for increasing groundnut yield.

Sustaining the Yield of Maize, Blackgram, Greengram, Groundnut, Cotton, Sugarcane, and Coconut through the Application of Nutrients and Plant Growth Regulator Mixture

“…TNAU groundnut-rich solution contains potassium which might improve the stomatal opening, resulting in an increased photosynthetic rate [ 41 ], and this was observed in the present study ( Table 10 ). Similarly, the application of inorganic fertilizers might have increased the availability of potassium, iron, magnesium and sulphur, resulting in increased chlorophyll content, photosynthetic rate, stomatal conductance, and transpiration rate [ 42 ], and a higher rate of translocation of photoassimilate from the source to its sink [ 43 ]. Chitdeshwari et al [ 44 ] demonstrated that in groundnut, the application of potassium during the flowering stage increased the number of flowers and pegs, and enhanced pod setting.…”
