Nutrient use effeciency, yield attributes and comparative economics of potato crop (Solanum tuberosum L.) in response to zinc and boron nutrition in entisols of India

Abstract

A field experiment was conducted during the winter (rabi) seasons of 2015-16 and 2016-17 at C-unit research farm of Bidhan Chandra Krishi Viswavidyalaya, Kalyani, Nadia, West Bengal, India to determine the effect of boron and zinc on growth and yield of potato under lower Gangetic plains of West Bengal. The experiment was laid out in a randomized block design with four replications having seven treatments viz. T1 (RDF of NPK 200:150:150 kg N: P2O5:K2O/ha), T2 (T1+2.0 kg B/ha as soil application), T3 (T1+ 4.5 kg Zn/ha as soil application), T4 (T1+2.0 kg B/ha and 4.5 kg Zn/ha as soil application), T5 (T1+ 0.1% boron (boric acid) as foliar application in three times at 40, 50 and 60 DAP), T6 (T1+ 0.1% zinc (zinc sulphate) as foliar application in three times at 40, 50 and 60 DAP) and T7 (T1+ Foliar spray of 0.1% zinc (zinc sulphate) + 0.1% boron (boric acid) at 40, 50 and 60 DAP). The soil of the experimental field was sandy loam in texture and slightly alkaline in reaction (pH 7.35) having an organic carbon content of 0.57%, 183.26 Kg available N/ha, 16.80 kg available P/ha, 132.00 kg available K/ha. The available Zn and B content of initial soil were 1.48 mg/kg and 0.86 mg/kg respectively. The results revealed that the highest values of various nutrient use and uptake efficiency parameters were recorded with the foliar application of Zn and B. Also, the same trend was observed where the highest value of harvest index of 83.20% and returns per rupee invested above farmer"s practice of 28.5% was observed in T7 (T1+ Foliar spray of 0.1% zinc (zinc sulphate) + 0.1% boron (boric acid) at 40, 50 and 60 DAP).

Effect of zinc and boron on the performance of rainy season local potato variety “Sete” (Solanum tuberosum L.) at Rukumkot, Rukum East, Nepal

“…The lowest number of leaves were observed in Control i.e., 51.27. These results were also supported by Lenka and Das (2019) and El-Dissoky and Kadar (2013).…”

“…The lowest number of large sized tubers were observed in 0.1% Zinc spray. Lenka & Das (2019) observed that soil application of only boron, only zinc and boron + zinc increased the total number of tubers by 3.9, 3.5 and 12.0%, respectively over the control.…”

“…Zinc and boron are the important micronutrients used in improving tuber and total dry weight of potato (Lenka and Das, 2019). Zinc increases ascorbic acid, decreases tyrosine and phenol content which imparts good quality to potato.…”

Effect of Zinc Oxide Nanoparticles on Growth, Chemical Composition and Yield of Potato (Solanum tuberosum L.).

“…Foliar spray ZnO-NPs at 80 mgL-1 per plant increased the weight of tubers per plant by (69.89 and 41.72%) and tubers weight per ha by (73.65 and 41.69%) during two seasons respectively. Several studies have reported that the application of ZnO-NPs had a positive effect on the yields of plants as Lenka and Das (2019) and Neogi and Das (2022) on potato and Adil et al (2022) on wheat. For several metabolic processes, Zn serves as an important element that activates enzymes.…”

Impact of Zinc Sulphate and Boric Acid Spraying on Production and Quality Characteristics of Potato Plants

“…In addition to being necessary for the production of auxins and chlorophyll cytochrome pigment, it also plays a significant part in the control of enzymes and carbohydrates, as well as in the growth of roots that are suitable for the circumstances. Through the processes of light-harvesting (photosynthesis) and nitrogen, synthesis, it (iron) serves as a cofactor [6,7].As a result of its high solubility, zinc sulphate is the kind of zinc IOP Publishing doi:10.1088/1755-1315/1371/4/042035 2 fertiliser that is used more often than any other type [8]. Boron is a microelement that is involved in the pathway of structural proteins important for many growth processes [9].Root and shoot growth, as well as plant development, are all influenced by it.…”
