“…Higher absorption of Zn is due to combined application of zinc through soil and foliar application which leads to higher absorption of zinc (Oseni, 2009). Our results of zinc uptake are in consonance with finding of Debnath et al (2018).…”

Background: Soils of North-Western Indo-Gangetic plains (IGP) are deficient in zinc content which may lead to lower forage yield of cowpea. Henceforth, the adequate supply of zinc either through soil or foliar spray and selection of suitable cultivar of cowpea could enhance the fodder productivity.Methods: A field experiment was laid out in factorial randomized block design during Kharif season, 2019 to assess the effect of different zinc management practices (control; 10 kg ZnSO4; 20 kg ZnSO4; 0.5% ZnSO4 foliar spray at 20 DAS; 0.5% ZnSO4 foliar spray at 20 and 40 DAS) on productivity and profitability of cowpea cultivars (C-152; MFC-08-14; MFC-09-1) and post-harvest fertility status of soil.Result: Cowpea cv. C-152 showed the highest growth attributes, green fodder yield, nutrient content as well as uptake and net returns. Among different zinc management practices, the application of 20 kg ZnSO4 as basal application or 0.5% ZnSO4 foliar spray at 20 and 40 DAS recorded significantly highest growth, green fodder yield, nutrient content as well as uptake and net returns. Significantly highest soil OC, available N, K and Zn were also noted under these treatments. It is inferred that cowpea cv. C-152 and application of either 20 kg ZnSO4 as basal or 0.5% ZnSO4 as foliar spray at 20 and 40 DAS were found the most productive and profitable approach and sustained the soil fertility status.

“…Borax pelleted seeds also recorded higher Zn uptake compared to control. The result is in conformity with the observation of Debnath et al (2018) who observed that application of B along with recommended dose of fertilizers increased the B uptake in grain cowpea. The B uptake by grain was the highest in ZnSO 4 primed seeds than in borax pelleted seeds.…”

Background: Cowpea [Vigna unguiculata (L.) Walp] is the most widely cultivated pulse crop of Kerala. Deficiencies of micronutrients viz., Zn and B are a common problem in cowpea. Foliar nutrition is very effective to correct the micronutrient deficiencies in pulses but it is too laborious. Seed pelleting and priming are two simple cost-effective methods to overcome the micronutrient deficiencies. The present study aimed to study the effect of seed invigouration with zinc sulphate and borax and to evaluate its effect along with Trichoderma viride on nutrient uptake and soil nutrient status of grain cowpea.Methods: The experiment was conducted at Coconut Research Station, Balaramapuram, Thiruvananthapuram, Kerala. The experiment was conducted in RBD with 8 seed invigouration treatments and a control during Rabi 2018.Result: Seed invigouration treatments had significant effect on nutrient uptake and nutrient availability. Seeds primed in ZnSO4 0.05 per cent for 4h recorded the highest NPK uptake by crop, the highest soil organic carbon content, available N and Zn status. Zinc uptake by crop and available soil K status were recorded the highest in seed primed in ZnSO4 0.05 per cent for 4h + Trichoderma viride seed treatment 10 g kg-1 seed. Boron uptake by crop and available soil B and P status were recorded the highest in seeds pelleted with borax 100 mg kg-1 seed. Hence it can be concluded that seed primed in ZnSO4 with 0.05 per cent for 4 h improved the Zn availability and uptake and seed pelleting with borax 100 mg kg-1 improved the B availability and uptake of grain cowpea.

“…Marsh and Waters (1985) reported that Zn deficiency in legumes reduces the size of nodules. Increase in nodule weight due to Zn fertilization was also reported by Desta et al (2015) and Debnath et al (2018).…”

The experiment was conducted at Coconut Research Station, Balaramapuram with an objective to assess the effect of seed invigouration with ZnSO 4 and borax alone and along with Trichoderma viride on physiological parameters and nodulation of grain cowpea. Seed invigouration treatments had significant effect on physiological parameters as well as nodulation parameters in grain cowpea. Leaf area index and total chlorophyll content were found to be higher in seeds primed in ZnSO 4 0.025 and 0.05 per cent for 4h at both 30 and 60 days after sowing (DAS). From 30 to 60 DAS, crop growth rate (CGR) and relative growth rate (RGR) were the highest in seeds pelleted with borax 50 mg kg -1 seed and from 60 DAS to harvest, seeds primed in ZnSO 4 0.05 per cent for 4h registered the highest CGR and RGR. Total number of nodules and effective nodules per plant were found to be higher in seeds pelleted with borax 50 and 100 mg kg -1 seed. However, the nodule fresh and dry weight were the highest in seeds primed in ZnSO 4 0.05 per cent for 4h. Hence it can be concluded that compared to seed pelleting with borax, seed priming with ZnSO 4 was found better for nodulation as well as better expression of physiological parameters in grain cowpea.
