Effect of Seed Invigouration on Yield Enhancement in Grain Cowpea Vigna unguiculata (L.) Walp

Abstract

Field experiment was conducted at Coconut Research Station, Balaramapuram with an objective to assess the effect of seed invigouration with zinc sulphate and borax on grain cowpea and to evaluate its effect along with Trichoderma viride on field emergence, growth, yield attributes and yield of the crop. Field emergence percentage was significantly influenced by seed invigouration and an enhancement in the germination percentage of 20.54 to 27.79 was observed compared to control. Seed priming with ZnSO4 @ 0.05 % for 4h recorded higher values of the growth attributes viz., green leaves per plant, branches per plant and dry matter production per plant. Yield attributes viz., pods per plant, pod weight per plant, pod length, pod girth and seed yield ha-1 were recorded the highest in seeds primed in ZnSO4 @ 0.05% for 4 h. Net returns and B: C ratio were also found to be the highest in the treatment, seed priming with ZnSO4@ 0.05 % for 4 h. Hence it can be concluded that, seed priming with ZnSO4 0.05% for 4 h can be recommended for better plant establishment, higher seed yield and net returns in grain cowpea.

Foliar Nutrition with Water Soluble Macro and Micro Nutrient Fertilizers for Yield Maximization in Bush Vegetable Cowpea

“…Addition of organic matter through FYM and decomposition of fallen leaves from the cowpea plant also paved for better availability of nutrients. Similar observations were also made by Raj (2019) in cowpea. Lower P uptake by the crop resulted in higher post-harvest P status in T 1 .…”

Zinc and boron nutrition in pulses: A review

“…Foliar application of ZnSO 4 0.05 per cent increased the Zn uptake from 18 to 37 per cent (Purushottam et al, 2018). Grain cowpea seeds primed in 0.05 per cent ZnSO 4 for 4 h recorded higher total uptake of N, P and K by crop (Raj, 2019).…”

“…Debnath et al (2018) who observed that application of B along with recommended dose of fertilizers increased the B uptake in grain cowpea. Raj (2019) observed that seed pelleting with borax significantly improved the B uptake in grain cowpea compared to control and it was also observed that compared to seed pelleting with 50 mg borax kg -1 seed, 100 mg borax kg -1 seed recorded higher uptake of B. Seema et al (2014) reported that N content in seeds significantly increased with the application of Zn in green gram.…”

“…Higher protein content was observed with soil application of Zn 5 kg ha -1 in cluster bean Kuniya et al (2018). Raj (2019) observed that among the various seed invigouration methods, seed priming with ZnSO 4 0.05 per cent for 4 h recorded higher crude protein content of grain. Debnath and Ghosh (2011) reported that B plays a major role in metabolism of protein and nucleic acids.…”

Influence of Nano Formulation on Augmenting the Seed Quality in Groundnut (Arachis hypogaea L.)

“…Jyothi and Hebsur (2017) reported that application of nano fertilizers may help in slow and steady release of nutrients and it also minimize the loss of nutrients and improves nutrient use efficiency. Also, Raj et al (2019) reported that application of Zinc sulphate nano particle as seed priming invigoration improved the seedling growth and establishment. The right seed coating plays a major role, wherein every coated seed has the opportunity to fulfil its Influence of Nano Formulation on Augmenting the Seed Quality in Groundnut (Arachis hypogaea L.) potential, which could be achieved through encapsulation of seeds with bioactive inputs incorporated nanoformulation.…”
